Placing the cooling radiator section in seawater rather than ambient air allows for the radiator to be smaller. The engine's cooling water may be used directly or indirectly for heating and cooling purposes of the ship. The Stirling engine has potential for surface-ship propulsion, as the engine's larger physical size is less of a concern.

A submarine torpedo tube is a more complex mechanism than a torpedo tube on a surface ship, because the tube has to accomplish the function of moving the torpedo from the normal atmospheric pressure within the submarine into the sea at the ambient pressure of the water around the submarine. Thus a submarine torpedo tube operates on the principle of an airlock.

Immediately investigations were started by the French authorities in Quimper. Several explanations were advanced to explain the capsizing including a fishing accident, collision with a surface ship, rock or wreck, the presence of a sandbank, and an accident involving a submarine. In June 2004 the ship was raised for forensic examinations. The fish hold showed a compression due to the water pressure.

U.S. Navy submarines are manned solely by volunteers from within the Navy. Because of the stressful environment aboard submarines, personnel are accepted only after rigorous testing and observation, as a consequence submariners have significantly lower mental hospitalization rates than surface ship personnel. Furthermore, submariners receive submarine duty incentive pay (SUBPAY) in addition to sea pay. Some 5,000 officers and 55,000 enlisted sailors make up the submarine force.

Following her year of routine training, Pintado deployed to the Western Pacific in August 1977. She was operating with Republic of Korea Navy vessels on 6 December 1977 when a South Korean surface ship abruptly turned toward her. She executed a crash dive, but the two ships collided, and Pintado sustained damage to the top of her rudder. She returned to San Diego in February 1978.

"Stealth" low-observability aircraft have gotten much attention, and new surface ship designs feature observability reduction. Operating in the confusing littoral environment produces a great deal of concealing interference. Of course, submariners feel they invented low observability, and others are simply learning from them. They know that going deep or at least ultraquiet, and hiding among natural features, makes them very hard to detect.

A ship's acoustic signature is not the only emission a torpedo can home in on: to engage U.S. supercarriers, the Soviet Union developed the 53–65 wake-homing torpedo. As standard acoustic lures can't distract a wake homing torpedo, the US Navy has installed the Surface Ship Torpedo Defense on aircraft carriers that uses a Countermeasure Anti-Torpedo to home in on and destroy the attacking torpedo.

NS Lenin was the world's first nuclear-powered surface ship as well as the first nuclear-powered civilian vessel, and NS Arktika became the first surface ship to reach the North Pole. A number of prominent Soviet aerospace engineers, inspired by the theoretical works of Nikolai Zhukovsky, supervised the creation of many dozens of models of military and civilian aircraft and founded a number of KBs (Construction Bureaus) that now constitute the bulk of Russian United Aircraft Corporation. Famous Russian airplanes include the first supersonic passenger jet Tupolev Tu-144 by Alexei Tupolev, MiG fighter aircraft series by Artem Mikoyan and Mikhail Gurevich, and Su series by Pavel Sukhoi and his followers. MiG-15 is the world's most produced jet aircraft in history, while MiG-21 is most produced supersonic aircraft. During World War II era Bereznyak-Isayev BI-1 was introduced as the first rocket-powered fighter aircraft, and Ilyushin Il-2 bomber became the most produced military aircraft in history.

The main failure of the SDV is its poor mobility. The SDV can only be effectively deployed from specially modified submarines and surface ships. Although it can be transported by C-130 airplanes, the relative scarcity of vessels capable of deploying an SDV limits its usage. Submarines are the preferred means of deployment, as enemies can see a surface ship deploying an SDV with a crane, further limiting the SDV's mobility and usage.

Though Luppis' original design had been rope guided, torpedoes were not wire-guided until the 1960s. During the First World War the U.S. Navy evaluated a radio controlled torpedo launched from a surface ship called the Hammond Torpedo. A later version tested in the 1930s was claimed to have an effective range of . Modern torpedoes use an umbilical wire, which nowadays allows the computer processing-power of the submarine or ship to be used.

The Project 1155 dates to the 1970s when it was concluded that it was too costly to build large-displacement, multi-role combatants. The concept of a specialized surface ship was developed by Soviet designers. Two different types of warships were laid down which were designed by the Severnoye Design Bureau: Project 956 destroyer and Project 1155 large anti-submarine ship. The Udaloy class are generally considered the Soviet equivalent of the American s.

With the Japanese fleet on the edge of victory, Admiral Hosogaya — not realizing the heavy damage his ships had inflicted and fearing American war planes would appear — retired without destroying his enemy. This amounted to a strategic defeat, as it ended Japanese attempts to resupply the Aleutian garrisons by surface ship, leaving only submarines to conduct supply runs. Hosogaya was accordingly retired from active service after the battle and assigned to govern a group of South Pacific islands.

Cruise missiles can be categorized by size, speed (subsonic or supersonic), and range, and whether launched from land, air, surface ship, or submarine. Often versions of the same missile are produced for different launch platforms; sometimes air- and submarine-launched versions are a little lighter and smaller than land- and ship-launched versions. Guidance systems can vary across missiles. Some missiles can be fitted with any of a variety of navigation systems (Inertial navigation, TERCOM, or satellite navigation).

At this time, Raeder and other senior officers began submitting memos to invade (among others) Shetland, Iceland, the Azores, Iran, Madagascar, Kuwait, Egypt and the Dutch East Indies. In January 1941, the battlecruisers Scharnhorst and Gneisenau were sent on a successful commerce raiding mission in the Atlantic. On 18 March, Raeder wanted to start firing on US warships even if unprovoked. He declined to invade the Azores on the grounds of the surface ship losses the previous year.

The colors blue and gold are traditionally associated with the U.S. Navy. The three interlaced chevronels represent the Crommelin brothers after whom the ship is named. The two winged chevronels refer to the air exploits of Lieutenant Commander Richard and Commander Charles Crommelin who served and died as Naval aviators. The central chevronel over which an anchor is placed alludes to the surface ship career of Vice Admiral Henry Crommelin, the second-oldest and first to serve of the brothers.

Other speeds include one-third, two-thirds, standard and full. One-third and two- thirds are the respective fractions of standard speed. Full is greater than standard but not as great as flank. In surface ship nuclear marine propulsion, the difference between full speed and flank speed is of lesser significance, because vessels can be run at or very near their true maximum speed for a long time with little regard for fuel expended, an important consideration for oil fuelled ships.

The design was originally intended to be used on destroyers in an anti-surface ship role. When it was first released, it was a highly advanced torpedo, but when it was actually deployed into service during World War II it was showing its age and unable to compete with modern torpedo technology. The low speed of the torpedo was one of the complaints; its Japanese counterpart, the Type 93 torpedo, was significantly faster and more difficult to spot in the water.

On 5 February 2003, Stethem returned to Puerto Vallarta, Mexico, for another port visit. Working with the San Diego and Puerto Vallarta Navy League Chapters, Stethem delivered medical equipment for distribution to handicapped residents of Puerto Vallarta. The crew also painted the local library frequented by many of Puerto Vallarta's school children. On 5 April 2003, Stethem successfully performed the first ever surface ship launch of a Block IV Tactical Tomahawk cruise missile, bringing it one step closer to fleet introduction.

The Whitehead Mark 1B torpedo, designated as a Torpedo Type B, was a variant of the Whitehead Mark 1 torpedo adopted by the United States Navy for use in an anti-surface ship role after the E. W. Bliss Company of Brooklyn, New York secured manufacturing rights in 1892. The primary differences between the Mark 1 and the Mark 1B were that the Mark 1B was longer, carried a heavier guncotton charge in the warhead and included an improved guidance system.

Madeline was the second of two storms during the season that originated in the upper air and surfaced over the western edge of the Pacific high cel. A surface ship on 2 September first gave indications of a relatively weak storm in the vicinity of 21 N and 151 E. The storm was discovered while in the process of recurvature; the track thereafter moving northward while missing Iwo Jima by 450 miles. Madeline dissipated into polar trough five days after it was detected.

The intensity of the lamps was adjusted to match the background sky as seen from an observer in a surface ship. Aircraft with Yehudi lights were not detected until away under conditions where aircraft without the lights were detected away. Though successful, the system was not put into production because of improved radar detection. During the Vietnam War, Yehudi lights were again tried, this time mounted to an F-4 Phantom painted in a dull blue- and-white camouflage pattern.

Bernard Lige Austin (15 December 1902 – 21 September 1979) was a Vice Admiral of the United States Navy. His career included service in World War II, the Korean War, and the Cold War and command of submarines and surface ship forces, during which he became a distinguished combat commander of destroyers. He also commanded the United States Second Fleet, held numerous diplomatic, educational, and administrative staff positions, and a served a lengthy tour of duty as President of the Naval War College.

PLAN destroyer conducting maritime interdiction operations at RIMPAC 2016 Until the early 1990s, the navy performed a subordinate role to the PLA Land Forces. Since then it has undergone rapid modernisation. The 240,000 strong People's Liberation Army Navy (PLAN) is organised into three major fleets: the North Sea Fleet headquartered at Qingdao, the East Sea Fleet headquartered at Ningbo, and the South Sea Fleet headquartered in Zhanjiang. Each fleet consists of a number of surface ship, submarine, naval air force, coastal defence, and marine units.

Agerholm tests an ASROC anti-submarine rocket armed with a nuclear depth bomb in 1962 On 11 May 1962, Agerholm participated in nuclear weapon testing in the Pacific in the "Swordfish" test, part of Operation Dominic. During this exercise the destroyer became the first surface ship to fire an antisubmarine nuclear weapon; the nuclear explosion occurring only about 4,000 yards from the ship. The submarine participated in the test, at the same distance as Agerholm. A video of this test is available from the Department of Energy.

The fjord's creation was documented by satellite images and the feature was first visited by surface ship in April 2006 during the U.S. Antarctic Program NBP06-03 cruise, when the extent, depth and dimension were determined by swath bathymetry. Named by US-ACAN in 2007 after Joshua Spillane who served the USAP as a marine technician aboard L.M. Gould and N.B. Palmer. He lost his life in Drake Passage, April 16, 2006, while L.M. Gould was transiting from Palmer Station to Punta Arenas, Chile.

This system also has potential for surface-ship propulsion, as the engine's size is less of a concern, and placing the radiator section in seawater rather than open air (as a land-based engine would be) allows for it to be smaller. Swedish shipbuilder Kockums has built 8 successful Stirling powered submarines since the late 1980s.Kockums (a) They carry compressed oxygen to allow fuel combustion submerged, providing heat for the Stirling engine. They are currently used on submarines of the Gotland and Södermanland classes.

It was, in fact, a hard and fast design criterion long before the SL-1, from the beginning of the Naval Reactors program, under the leadership of Admiral Hyman Rickover. This design criterion started with the , and continued throughout subsequent submarine and surface ship designs, and with the Shippingport civilian nuclear plant. It continues to be a requirement for all U.S. reactor designs to this day. Although portions of the center of the reactor core had been vaporized briefly, very little corium was recovered.

The AN/UYK-43 was the standard 32-bit computer of the United States Navy for surface ship and submarine platforms, starting in 1984. Some 1250 units had been delivered through 2000. The size of a refrigerator, it replaced the older AN/UYK-7, both built by UNISYS and shared the same instruction set. An enhancement to the UYK-43, the Open Systems Module (OSM), allows up to six VMEbus Type 6U commercial off-the-shelf (COTS) cards to be installed in a UYK-43 enclosure.

Promoted to the rank of commander on 30 June 1983, he assumed command of the frigate HMS Phoebe. The frigate operated in NATO waters, at the time of the RN’s first operational experience with surface ship towed passive sonar. In 1985 he attended the Joint Services Defence College and was soon appointed to the Defence Staff in the Ministry of Defence in the Directorate of Defence Policy. Promoted to captain on 30 June 1988, he left the Directorate of Policy and commanded HMS Norfolk.

Moving east, she patrolled initially off Meinderts Reef, off the northeast coast of Java; then headed north to round the eastern end of Madoera Island en route to Bawean Island. On 26 February, she shelled Japanese facilities at Sangkapura; then patrolled between Bawean and the western approach to Soerabaja. On 28 February, she picked up 58lair, p.186. survivors from destroyer , sunk the day before at the Battle of the Java Sea; and, on 1 March, transferred the British sailors to a surface ship in Madoera Strait.

On 14 August 2000, as vice-premier, President Putin put him in charge of the Kursk rescue operation following its disastrous sinking. On 29 or 20 August, he announced that the likely cause of the sinking was a "strong 'dynamic external impact' corresponding with 'first event'", probably a collision with a foreign submarine or a large surface ship, or striking a World War II mine. This later proved to be completely unfounded. In February 2002, Putin designated Klebanov as Minister of Industry, Science and Technology.

On the way home, Asheville conducted an Operational Reactor Safeguard Examination (ORSE). The ORSE team was brought on board 1 July. After a night of successful "Drilling and Spilling", the ORSE Board gave Asheville a high score. She returned to Pearl Harbor in time for Fourth of July celebrations, to the sound of the submarine and surface ship whistles, on 2 July. During this deployment, Asheville reported to; COMSUBRON III, COMSUBGRU 7, CTF-74, CTF-54, as well as the Commander of Carrier Strike Group Seven.

On 17 October, surface ship reports from the Truk area gave the first indication of the tropical disturbance later named Patricia. As it moved slowly northwestward it began to intensify such that a definite closed circulation was apparent with the passage-southwest of Guam on 20 October. At this time, the storm' was in the process, of recurvature and continued thereafter on a northeasterly track which skirted all U.S. Military installations. Patricia traversed over 3,000 miles in the eleven days it was under surveillance.

With a complete repair department on board, she could repair any surface ship that did not need a dry dock for hull repairs. A dive shop allowed for underwater repairs to be made, however such repairs were limited. Outfitted with two stationary center-mast main cranes, she could move heavy equipment to and from other ships or docks to be repaired and then reinstalled. Two smaller traveling cranes could move up and down each side of the aft portion of the ship's upper deck, which allowed equipment to be moved virtually anywhere needed.

The Hoot (; Whale) is an Iranian supercavitation torpedo claimed to travel at approximately , several times faster than a conventional torpedo. It was claimed to have been successfully test-fired from a surface ship against a dummy submarine during the Iranian military exercise "Great Prophet" () on 2 April 2006 and 3 April 2006. Iran test-fired the torpedo within its territorial waters in the Strait of Hormuz in May 2017. The official Iranian news agency IRNA claims the torpedo was produced and developed by the Islamic Revolutionary Guard Corps ().

During this survey, the deepest part of the trench was recorded when the Challenger II measured a depth of at , known as the Challenger Deep. In 1957, the Soviet vessel reported a depth of at a location dubbed the Mariana Hollow. In 1962, the surface ship M.V. Spencer F. Baird recorded a maximum depth of using precision depth gauges. In 1984, the Japanese survey vessel Takuyō (拓洋) collected data from the Mariana Trench using a narrow, multi-beam echo sounder; it reported a maximum depth of , also reported as ±.

The DEstroyer Life EXtension (DELEX) refit was born out of the need to extend the life of the steam-powered destroyer escorts of the Canadian Navy in the 1980s until the next generation of surface ship was built. Encompassing all the classes based on the initial St. Laurent (the remaining St. Laurent, Restigouche, Mackenzie, and Annapolis- class vessels), the DELEX upgrades were meant to improve their ability to combat modern Soviet submarines,Milner, pp. 277–278 and to allow them to continue to operate as part of NATO task forces.Gimblett, p.

In 1966 Glover was modified in the Boston Naval Shipyard with electronic testing and data recording hardware and one of the first digital computers on a surface ship, a Digital Equipment Corporation PDP-8. She was also outfitted with a prototype naval tactical data system for a time. In 1968 she re-entered the Boston Naval Shipyard for more modifications and the addition of a variable depth sonar device. In 1970, she made her first Atlantic crossing and Mediterranean cruise visiting ports in Spain, France, Italy, and Greece.

Thales will provide an integrated mine countermeasure combat system, including the mine information system, a hull- mounted sonar, a towed synthetic aperture sonar and expendable mine disposal systems. The towed synthetic sonar array is the DUBM 44, an unmanned underwater vehicle that uses onboard processing of digital signals to provide high-resolution imagery. The DUBM 44 is not autonomous and is connected by cable to the surface ship. Thales will also be in charge of making any structural alterations to the vessels in relation to the integration of new systems and equipment.

The introduction of the Grumman WF-2 Tracer (later the E-1 Tracer) carrier-based airborne early warning aircraft in 1958 doomed the radar picket as a carrier escort. Airborne radar had evolved to the point where it could warn of an incoming attack more efficiently than a surface ship. In 1961 the DDRs and SSRs were withdrawn. All but six DDRs received anti-submarine warfare conversions under the FRAM I and FRAM II programs and were redesignated as DDs; the remaining six were somewhat modernized under FRAM II and retained in the DDR role.

The crew prepared the ship for the most demanding and complex surface ship shock trial test in the history of the Navy. The ship has completed four deployments to the Persian Gulf. On 7 October 2001, John Paul Jones launched the first Tomahawk missiles into Afghanistan as part of Operation Enduring Freedom. In June 2010 she began a ten-month yard period during which her machinery control system and many HM&E; systems were upgraded. This was a first in class effort, similar to the CG-47 mid life upgrade undertaken on the hull.

The more senior the officer, the larger the ship. Others may hold command as commodores of destroyer squadrons (DESRON) consisting of multiple destroyers and frigates. Surface Warfare Officers may also command large deck amphibious warfare ships or combat support ships and also serve as commodores of amphibious squadrons (PHIBRON) or other type of surface ship squadrons. In the submarine community, a captain typically commanded a nuclear-powered ballistic missile submarine (SSBN) until the early 21st century when the requisite rank for the position was downgraded to that of a commander.

The ship participated in the Battle of Jutland, where she was sunk with heavy loss of life. The circumstances under which she sank were mysterious for some years after. As the British had lost contact and did not see the ship destroyed, they were unsure as to whether a submarine or surface ship was responsible for sinking Black Prince.Jellicoe 1919, p. 477. During the battle, the 1st Cruiser Squadron was deployed as part of a screening force several miles ahead of the main force of the Grand Fleet,Campbell 1998, p. 36.

The first ASROC system using the MK-112 "Matchbox" launcher was developed in the 1950s and installed in the 1960s. This system was phased out in the 1990s and replaced with the RUM-139 Vertical Launch ASROC, or "VLA". After a surface ship, patrol plane or anti- submarine helicopter detects an enemy submarine by using sonar or other sensors, it could relay the sub's position to an ASROC-equipped ship for attack. The attacking ship would then fire an ASROC missile carrying an acoustic homing torpedo"Asroc" in The New Encyclopædia Britannica.

After witnessing firsthand the dangers of deploying and retrieving BTs, James M. Snodgrass began developing the expendable bathythermograph (XBT). Snodgrass' description of the XBT: > Briefly, the unit would break down in two components, as follows: the ship > to surface unit, and surface to expendable unit. I have in mind a package > which could be jettisoned, either by the “Armstrong” method, or some simple > mechanical device, which would at all times be connected to the surface > vessel. The wire would be paid out from the surface ship and not from the > surface float unit.

In 1958 an American nuclear submarine, the Nautilus was the first ship to reach the North Pole. In the decades that followed submarines regularly roamed under the Arctic sea ice, collecting sonar observations of the ice thickness and extent as they went. These data became available after the Cold War, and have provided evidence of thinning of the Arctic sea ice. The Soviet navy also operated in the Arctic, including a sailing of the nuclear-powered ice breaker Arktika to the North Pole in 1977, the first time a surface ship reached the pole.

When representing frequencies generated by propeller blades or machinery those could form a submarine or surface ship signature that could be recognized and used to locate and identify the source. The frequency against time line can show frequency variations from a specific source and thus changes in behavior of the source. With regard to vessels that could be speed or other changes, including a Doppler shift indicating direction changes, having an effect of frequencies received.The lofargram illustration at the top illustrates such a distinctive frequency shift in a line.

The Bliss-Leavitt Mark 2 torpedo was a Bliss-Leavitt torpedo adopted by the United States Navy for use in an anti-surface ship role after the E. W. Bliss Company of Brooklyn, New York, which had been building Whitehead torpedoes for the US Navy, began designing and manufacturing their own torpedoes in 1904. It was the first American-built torpedo to feature counter-rotating turbines, each driving a propeller. This design eliminated the unbalanced torque that contributed to the tendency of its predecessor (the Bliss-Leavitt Mark 1 torpedo) to roll.

Quiet Electric Drive (QED)—sometimes called by the misnomer Quiet Electronic Drive—is an ONR-sponsored program to develop technologies for silent maritime propulsion for the United States Navy. According to the ONR, QED's role is to "address the Navy's operational gaps in surface ship and submarine maneuverability and acoustic signature. Quiet Electric Drives, or QEDs, are quiet, efficient and power dense. The primary objective of QED is demonstrating the utility of the motor as an actuator to obtain signature reduction performance while increasing tactical speed and maneuverability".

It is the first time that a Royal Navy or British Government vessel has operated in the waters south of Australia and New Zealand since 1936. In addition to the ship's usual equipment, three unmanned aerial vehicles (designed and 3D printed by the University of Southampton) were embarked. Sailing from Devonport, Protector visited the Seychelles and Diego Garcia en route (in the latter instance, becoming the first Royal Navy surface ship to visit in eight years) before proceeding to Tasmania, Australia. At the start of December, Protector departed from Hobart, Tasmania to commence fisheries patrols.

In the Eastern Mediterranean, British and French ships would patrol up to the Dardanelles, but not in the Adriatic Sea. In this area, signatory countries would patrol their own territorial waters, and would provide any reasonable assistance to the French and British patrols. The future revision of these provisions, including the way the area had been divided into zones, was specifically allowed. Submarine activity would be banned, subject to two exemptions: travel on the surface accompanied by a surface ship, and activity in certain areas for training purposes.

On 23 December, the Admiralty endorsed the conclusions of the meeting due to the effect of submarines and mines on surface ship operations. Scheer was unimpressed by the Zeppelin reconnaissance, only three had spotted anything and of their seven reports four had been wrong. This was the last occasion on which the German fleet travelled so far west into the North Sea. On 6 October, the German government resumed attacks against merchant vessels by submarine, which meant the U-boat fleet was no longer available for combined attacks against surface vessels.

Her sail was streamlined and enlarged to house the snorkel, a device added to allow her to operate on diesel power at periscope depth and to recharge her batteries while running submerged. All of these changes helped to convert Tusk from simply a submersible surface ship into a truer submarine. They increased her submerged range; and, though she lost about two knots in surface speed, her submerged speed increased from just under to about . The newly converted submarine returned to active duty early in the summer of 1948.

The Mark 20 torpedo was a US torpedo designed in 1943 but never used in service. Design was by Naval Torpedo Station Newport, the Electric Storage Battery Company and General Electric. This project was a continuation of the development of a submarine-launched, anti-surface ship torpedo originally designated Mark 2 in 1941 which was the second attempt to develop a torpedo of this type. The earlier effort, designated Mark 1, in post-World War I years (1919–1931), was terminated after the torpedo produced proved unsatisfactory in speed and range.

While Ballard had been interested in the sea since an early age, his work at Woods Hole and his scuba diving experiences off Massachusetts spurred his interest in shipwrecks and their exploration. His work in the Navy had involved assisting in the development of small, unmanned submersibles that could be tethered to and controlled from a surface ship, and were outfitted with lighting, cameras, and manipulator arms. As early as 1973, he saw this as way of searching for the wreck of the Titanic. In 1977, he led his first expedition, which was unsuccessful.

"LPD-21 New York". Retrieved: 18 June 2016 In his letter, the Governor said he understood state names were reserved for submarines but asked for special consideration so the name could be given to a surface ship.

She made Kataoka Bay at Paramushiro on 22 June 1943. I-2 departed Paramushiro again at 16:00 on 29 June 1943 in company with the submarines and , tasked this time with supporting the Kiska evacuation by providing weather reports from an area north of Adak Island. While she was entering Amchitka Pass on 5 July 1943, an Allied surface ship detected her at 03:45 and pursued her for 18 hours, depth- charging her twice. She finally arrived in her patrol area on 10 July 1943 and transmitted her first weather report that day.

La Motte-Picquet (D 645). A towed array sonar is a system of hydrophones towed behind a submarine or a surface ship on a cable. Trailing the hydrophones behind the vessel, on a cable that can be kilometres long, keeps the array's sensors away from the ship's own noise sources, greatly improving its signal-to-noise ratio, and hence the effectiveness of detecting and tracking faint contacts, such as quiet, low noise-emitting submarine threats, or seismic signals. A towed array offers superior resolution and range compared with hull mounted sonar.

However, the only weapon that had been integrated and test- fired on the ships was still the Bofors 57 Mk3 gun. The FMV calls this version 4, which aims to get the ships into service and start training crews. HSwMS Visby Version 5 is due in 2012 and is intended to supplement the ships with mine clearance systems, helicopter landing capability (only K31 is certified to date), anti-surface ship missiles, and additional stealth adaptation. Visby was the first of the corvettes to be upgraded to Version 5.

The AN/UYK-7 was the standard 32-bit computer of the United States Navy for surface ship and submarine platforms, starting in 1970. It was used in the Navy's Aegis combat system and U.S. Coast Guard,AN/UYK-7 MAINTENANCE ASSIST MODULE (MAM) KITS and the navies of U.S. allies. It was also used by the U.S. Army. Built by UNIVAC, it used integrated circuits, had 18-bit addressing and could support multiple CPUs and I/O controllers (three CPUs and two I/O controllers were a common configuration).

They displayed prominent "surface-ship" characteristics, notably high freeboard and an expansive deck structure. Each was powered by two 10-cylinder, two-stroke, MAN diesel engines (designed by the German firm that built engines that powered many German U-boats of World War I, the rights to which the U.S. Navy purchased to build domestically for their own submarines). They also had a pair of smaller diesel-powered generators for charging batteries or augmenting the main propulsion engines on the surface. On trials, the two boats achieved nearly surfaced and submerged, and their claimed endurance was at .

When the Nazis came to power in 1933, Adolf Hitler soon began to more brazenly ignore many of the Treaty restrictions and accelerated German naval rearmament. The Anglo- German Naval Agreement of 18 June 1935 allowed Germany to build a navy equivalent to 35% of the British surface ship tonnage and 45% of British submarine tonnage; battleships were to be limited to no more than 35,000 tons. That same year the Reichsmarine was renamed as the Kriegsmarine. In April 1939, as tensions escalated between the United Kingdom and Germany over Poland, Hitler unilaterally rescinded the restrictions of the Anglo-German Naval Agreement.

Jack Hardy is the only surviving member of the original crew, having been found floating and rescued in 1943 by members of Nazi Germany's Kriegsmarine; but he has no memory of the last days of the 1943 mission. He and Alan Cassidy, one of the vessel's designers, join a Royal Navy crew on a mission to retrace Scorpion's last days before it went missing. Commander Travis, a naval intelligence officer, is in charge of the mission while Captain Byrnes captains the submarine. The mission will take the submarine into Soviet waters, and a surface ship, HMS Oakland, escorts the boat.

She conducted ASW and anti-surface ship exercises during this period, highlighted by a successful Standard missile shot in early May. Back in Pearl Harbor on 12 May, Benjamin Stoddert did not leave Hawaii until 18 June when she set out for Central America and another Coast Guard law enforcement deployment. The warship began patrol operations off Baja California on the 27th and remained there — save for a single port visit to San Diego — through 11 August. After rendezvousing with Badger (FF-1071) and Kawishiwi (AO-146), the guided-missile destroyer sailed south for a drug interdiction patrol off Panama.

They were widely used in World War I and World War II. They remained part of the anti- submarine arsenals of many navies during the Cold War. Depth charges have now largely been replaced by anti-submarine homing torpedoes. The Mk 101 Lulu was a US nuclear depth bomb operational from 1958-1972 A depth charge fitted with a nuclear warhead is also known as a "nuclear depth bomb". These were designed to be dropped from a patrol plane or deployed by an anti-submarine missile from a surface ship, or another submarine, located a safe distance away.

After 33 years of reliable icebreaking, having become the first surface ship to reach the North Pole in 1977, and the first civilian ship to spend more than a year at sea without making port in 2000, and covering more than a million nautical miles by 2005, Arktika was retired in October 2008."Arktika rests after 33 years of icebreaking", world-nuclear- news.org, October 7, 2008. She is docked at Atomflot, the nuclear base and dock in Murmansk, away from the main docks, where she will remain until policies can be drawn up to dismantle her.

Only six bodies were recovered, one of which couldn't be identified. Goorangai and her ship's company were the RAN's first loss in World War II, and the first RAN surface ship ever to be sunk while in service. News of the accident quickly spread in Melbourne, as the media outlets decided that as the loss of life was due to an accident and not military action, censorship restrictions did not reply. The Australian Commonwealth Naval Board disagreed, and the War Cabinet later issued supplementary instructions preventing the publishing of any loss of Australian personnel or equipment without approval.

A semi-submersible naval vessel is a hybrid warship, that combines the properties of a surface ship and submarine by using water ballast to partially immerse and minimize its above-waterline profile, thereby improving its stealth characteristics when in hostile waters. The was an antecedent to such craft with its low-profile deck and gun turret. Russian and North Korean semi- submersible naval vessels evolved from torpedo boats and special forces boats that could partially submerge (sometimes to snorkel depth) to perform their missions. The US Navy SEALs use such vessels for clandestine special forces actions.

Because the decisive moment of the battle occurred when the Austrian flagship Erzherzog Ferdinand Max successfully sank the Italian flagship Re d'Italia by ramming, in subsequent decade every navy in the world largely focused on ramming as the main tactic. The last known use of ramming in a naval battle was in 1915, when rammed the (surfaced) German submarine, U-29. The last surface ship sunk by ramming happened in 1879 when the Peruvian ship Huáscar rammed the Chilean ship Esmeralda. The last known warship equipped with a ram was launched in 1908, the German light cruiser .

The Greek destroyer Vasilefs Georgios was captured in damaged condition after the fall of Greece, then repaired in Greece with assistance from the Germaniawerft and commissioned by the Kriegsmarine as the ZG3 or the Hermes. She was the only major Kriegsmarine surface ship in the Mediterranean Sea during World War II, and she was involved in escorting convoys to North Africa and the Aegean Islands. Hermes detected and depth charged the Royal Navy submarine HMS Splendid off Capri, Italy, on 21 April 1943, forcing it to surrender; Splendid was scuttled by her crew. Hermes was damaged by air attacks off Tunisia.

The long-hull ships also carry the RAST (Recovery Assist Securing and Traversing) system (also known as a Beartrap (hauldown device)) for the Seahawk, a hook, cable, and winch system that can reel in a Seahawk from a hovering flight, expanding the ship's pitch-and-roll range in which flight operations are permitted. The FFG 8, 29, 32, and 33 were built as "short-hull" warships but were later modified into "long-hull" warships. Oliver Hazard Perry-class frigates were the second class of surface ship (after the s) in the US Navy to be built with gas turbine propulsion.

An anti-submarine school HMS Osprey and a training flotilla of four vessels were established on Portland in 1924. By the outbreak of World War II, the Royal Navy had five sets for different surface ship classes, and others for submarines, incorporated into a complete anti-submarine system. The effectiveness of early ASDIC was hampered by the use of the depth charge as an anti-submarine weapon. This required an attacking vessel to pass over a submerged contact before dropping charges over the stern, resulting in a loss of ASDIC contact in the moments leading up to attack.

In 2003 however the company was split into BAE Systems Submarines and BAE Systems Naval Ships, with Barrow ceasing surface ship construction. Since its completion in 1986, submarines at Barrow are constructed inside the Devonshire Dock Hall (DDH). The company is currently constructing the s, a new generation nuclear attack submarine (SSN) for the Royal Navy, the first of which was launched on 8 June 2007.New UK nuclear submarine launched The order for the initial batch of three ships was placed in 1997, with Marconi Marine (VSEL), which was absorbed into BAE Systems in 1999.

Late on 24 June, Van Valkenburgh finally left the forward areas, bound for the Philippines. For the ensuing fortnight, the ship rested at San Pedro Bay, Leyte, enjoying a breather from the hectic pace of operations that had lasted for over two months. Early in July, she put to sea as part of a surface force consisting of the new large cruisers and , four light cruisers, and seven destroyers. Assigned to operate along the China coast between Formosa and Shanghai, the force searched for any signs of Japanese surface ship activity in that area but found no opposition of any kind.

In April 1968, Soviet Pacific Fleet surface and air assets were observed conducting a surge deployment to the North Pacific Ocean that involved some unusual search operations. The activity was evaluated by the United States Office of Naval Intelligence (ONI) as a possible reaction to the loss of a Soviet submarine. Soviet surface ship searches were centered on a location known to be associated with Soviet Golf II-class strategic ballistic missile (SSB) diesel submarine patrol routes. These submarines carried three nuclear missiles in an extended sail/conning tower, and routinely deployed within missile range of the US west coast.

Soon after the bomber attack, U-156 resumes her hunting duties, leaving behind the lifeboats with the British survivors to be picked up by a Vichy naval surface ship sent by Admiral Dönitz. While admiring Hartenstein's actions, Dönitz also reluctantly composes the Laconia Order to other U-boat commanders not to rescue survivors in future. The French ship arrives; one lifeboat leaves the others to make for the coast of west Africa, which it eventually reaches. One British merchant officer is injured in the American attack and remains with U-156 until it reaches port, where he is taken prisoner.

In June 1998, she returned to La Maddalena, Italy. Simon Lakes performance during her last two years of service was particularly noteworthy. Not only did she receive the awards associated with the Persian Gulf but she was nominated for the Secretary of Defense Maintenance Award, received the 1997 and 1998 Battle Efficiency 'E' award the 1998 Chief of Naval Operations Safety Award, the 1998 Golden Anchor award, and she became the first surface ship to receive both the Enlisted Surface Warfare and the Surface Warfare Officer pennants. After being relieved by , Simon Lake departed La Maddalena on 11 May 1999 and crossed the Atlantic for Norfolk, Virginia to be decommissioned.

The ship is in length, displaces fully loaded and can exceed . The design incorporates a large reconfigurable seaframe to allow rapidly interchangeable mission modules, a flight deck with integrated helicopter launch, recovery and handling system and the capability to launch and recover boats (manned and unmanned) from both the stern and side. The flight deck is 1.5 times the size of that of a standard surface ship, and uses a Trigon traversing system to move helicopters in and out of the hangar. The ship has two ways to launch and recover various mission packages: a stern ramp and a starboard side door near the waterline.

NROTC students who are on scholarship participate in a summer cruise in the fleet, to get hands-on training with real Navy personnel and equipment. After their freshman year, Midshipmen (both Navy and Marine) travel to either San Diego or Norfolk for CORTRAMID (Career Orientation and Training of Midshipmen). The Midshipmen spend a week in each of the three primary Unrestricted Line communities (Surface, Submarine, and Aviation) as well as a week with the Marine Corps to help them decide which community to join when commissioned. In the next two summers, Navy Option scholarship midshipmen spend time with either a surface ship, submarine, or aviation squadron.

Map of known Kaiten base locations at the end of World War II A Kaiten Type 1 being trial-launched from the light cruiser Kitakami Kaiten were designed to be launched from the deck of a submarine or surface ship, or from coastal installations as a coastal defence weapon. The cruiser Kitakami was equipped to launch Kaiten and took part in sea launch trials of Type 1s. In addition, several destroyers of the Matsu class were also adapted to launch the weapon.Whitley, M.J., "Destroyers of World War II", page 207 In practice, only the Type 1 craft, using the submarine delivery method, were ever used in combat.

This was followed up on 8 May with the first surface ship launch of a Block IV Tactical Tomahawk cruise missile with a live warhead. After the missile left the launcher, Stethems strike team became the first to demonstrate Tactical Tomahawk's post launch execution capability when they redirected the missile in flight. Both the team and the missile performed without error, destroying the intended target on San Clemente Island after over 2 hours and 700 miles of missile flight. Stethem launches a Tomahawk, May 2003 On 14 May 2003, after a two-week intermediate maintenance availability, Stethem sailed in support of a different kind of missile-firing exercise.

In 1994, the USS Cowpens (CG 63) was awarded the coveted U.S. Pacific Fleet Spokane Trophy for the top operational combat systems readiness performance in the fleet for a surface ship. Captain Edward Moore Jr. was the first commanding officer of Cowpens. Vice Admiral Moore was Commander of Naval Surface Force, U.S. Pacific Fleet, from August 1998 to May 2001. Captain W. Dallas Bethea was the second commanding officer of Cowpens. He relieved Captain Moore, who had just been promoted to rear admiral, on February 2, 1993 in Bahrain and was on board when the ship took part in the Tomahawk strike on January 17.

As with Polaris, starting a rocket motor when the missile was still in the submarine was considered very dangerous. Therefore, the missile was ejected from its launch tube using high pressure steam produced by a solid- fueled boiler. The main rocket motor ignited automatically when the missile had risen approximately above the submarine. The first test launch took place on 16 August 1968, the first successful at-sea launch was from a surface ship, the (from July 1 to December 16, 1969), earning the ship the Meritorious Unit Commendation, and the first test launch from a submarine took place on the on 3 August 1970.

The Mark 25 torpedo was an aircraft-launched anti-surface ship torpedo designed by the Division of War Research of Columbia University in 1943 as a replacement for the Mark 13 torpedo. It was designed for higher speed, greater strength and more ease of manufacture compared to the Mark 13. Naval Ordnance Station Forest Park built twenty-five units in 1946 for test and evaluation, however, this torpedo was never mass-produced due to the large inventory of Mark 13s left over at the end of World War II. Moreover, the role of Naval aircraft changed from a torpedo strike platform to an antisubmarine warfare platform.

She arrived at her destination on 1 August 1990. Barbey and her crew transitioned from a peacetime deployment in a moderate threat environment, to a wartime deployment when the forces of Iraq, under the orders of Saddam Hussein, invaded the Emirate of Kuwait.e Barbey, and her sailing mate for the transit, USS England, were immediately employed in Naval Operations to enforce the sanctions specified by UN Resolutions. During her deployment in the AG, Barbey and her embarked helicopter detachment, HSL-35 "Magus 32" provided support for the UN Resolutions and performed more surface ship interdiction intercepts than any other fleet unit in the AG during the period.

As a result, the Japanese Navy had to relocate the Combined Fleet's forward base to the Palau Islands, and eventually to Indonesia, and the Fleet had begun clearing its major warships out of Truk before the Hailstone attack struck. Nevertheless, the Hailstone attack on Truk caught a good number of Japanese auxiliary ships and cargo ships in the harbor, as well as some warships. Between the air attacks and surface ship attacks over the two days of Operation Hailstone, the worst blow against the Japanese was about 250 warplanes destroyed, with the concurrent irreplaceable loss of experienced pilots. Also, about forty ships — two light cruisers, four destroyers, nine auxiliary ships, and about two dozen cargo vessels — were sunk.

Most naval vessels today are equipped with long range anti- surface missiles such as Harpoon and Exocet which are capable of crippling or destroying enemy ships with a single hit. These can be fired from vertical launch systems or from stand alone launch tubes and are designed to attack other warships. Smaller ships such as the US Navy's littoral combat ship make use of smaller missiles, such as the AGM-114 Hellfire, in the surface-to- surface role that are less suited to attack warships but are still dangerous against fast attack craft or smugglers and pirates as well as land targets. A surface ship has several key disadvantages as ship to ship missile platform compared to other combatants.

The temperature in the cabin was a mere at the time. While on the bottom at maximum depth, Piccard and Walsh unexpectedly regained the ability to communicate with Wandank using a sonar/hydrophone voice communications system. At a speed of almost (about five times the speed of sound in air), it took about seven seconds for a voice message to travel from the craft to the surface ship and another seven seconds for answers to return. While on the bottom, Piccard and Walsh reported they observed a number of small sole and flounder swimming away, indicating that at least some vertebrate life might withstand the extremes of pressure in any of the Earth's oceans.

An advantage of a hot-launch system is that the missile propels itself out of the launching cell using its own engine, which eliminates the need for a separate system to eject the missile from the launching tube. This potentially makes a hot-launch system relatively light, small, and economical to develop and produce, particularly when designed around smaller missiles. A potential disadvantage is that a malfunctioning missile could destroy the launch tube. American surface-ship VLSs have the missile cells arranged in a grid with one lid per cell and are "hot launch" systems; the engine ignites within the cell during the launch, and thus it requires exhaust piping for the missile flames and gasses.

Introduction to Naval Special Warfare For military use, the operator will sometimes use a rebreather device so as not to leave a trail of bubbles. Military wet subs are deployed from a larger submarine or from a surface ship. The SEAL Delivery Vehicle (SDV) used by the United States Navy SEALs and British Special Boat Service is an example that is in use today. The SDV is used to insert Navy SEALs in shallow coastal waters or attack surface ships SEAL Delivery Vehicle Team Two launch a wet sub from Los Angeles-class submarine The Motorised Submersible Canoe, developed by the British Special Operations Executive during World War II, is another example.

S-117 was a Soviet Shchuka class submarine that was lost on or about December 15, 1952, due to unknown causes in the Strait of Tartary in the Sea of Japan. The boat may have collided with a surface ship or struck a mine. All forty-seven crewmen died in the incident. The southeastern part of the Strait of Tartary was the site of one of the tensest incidents of the Cold War, when on September 1, 1983, Korean Air Lines Flight 007, carrying 269 people including a sitting U.S. congressman, Larry McDonald, strayed into the Soviet air space and was attacked by a Soviet Su-15 interceptor just west of Sakhalin Island.

Rear Admiral Richard Brown was named to lead an internal investigation of the accident. Brown is a former commander of another sister ship, and currently serves as commander of Naval Personnel Command and deputy chief of Naval Personnel. On 18 September 2017, the new U.S. 7th Fleet commander, Vice Admiral Phillip Sawyer, as part of the investigations into four surface ship incidents involving Navy ships in the Western Pacific in 2017, including the collision involving John S. McCain, ordered that Rear Admiral Charles Williams, Commander Task Force 70, and Captain Jeffrey Bennett, commodore of Destroyer Squadron 15, be removed from their positions due to a loss of confidence in their ability to command.

McLaughlin, pp. 380–82 The design of KB-4, the surface ship design bureau of the Baltic Shipyard, was selected for further development although the lead designers were convinced that only a larger ship could fulfill the ambitious requirements. They did manage to get agreement on 22 November 1936 for a thickening of the deck armor that raised the displacement to about 47,000 tons. Design work continued on this basis and technical work was completed for a ship of 47,700 tons in April 1937, but the designers continued to press their case for larger ships. The issue was resolved by Premier Stalin at a meeting on 4 July when he agreed to increase displacement to about 56,000 tons.

In October 2009 the group signed a MOU with ThyssenKrupp Marine Systems (TKMS) that involved the establishment of a 50/50 joint venture for the construction of naval surface ships. As per the partnership agreement signed by the two companies, the 50/50 joint venture would see TKMS retain a lead role and know-how in all projects with the German Navy and NATO partners; while Abu Dhabi MAR Group was responsible for the Middle East and North Africa (MENA). It was also agreed that Abu Dhabi MAR would be acquiring 80% of TKMS' key three surface ship firms: Blohm + Voss Shipyards, Blohm + Voss Repair GmbH, and Blohm + Voss Industries. In September 2010 Abu Dhabi MAR purchased 75.1% of TKMS's Greek subsidiary Hellenic Shipyards Co. at Skaramangas.

The Battle of the North Cape took place only a few months after the successful Operation Source, which had severely damaged the German battleship Tirpitz as she lay at anchor in Norway. With Scharnhorst destroyed and Germany's other battleships out of service, the Allies were now for the first time in the war free from the threat of German battleships raiding their convoys in the Arctic and Atlantic. This would allow the Allies to reallocate their naval resources that had been previously tied up to counter the threat of the German 'fleet in being'. This would prove to be the final battle of battleships in European waters and was one of few major surface ship-on-ship battles in the Second World War without air support.

ALVIN submersible of Woods Hole Oceanographic Institution in 1978 A significant obstacle in marine surveys was the use of echo sounders with a wide transmit beam, which smeared-out details of the sea floor features. The crustal accretion or creation process was thought to take place over a few kilometers width of sea floor, which was below the resolution of ship echo sounders. Thus, near-bottom and on-bottom approaches were employed along with new sonar mapping tools. Investigations included airborne magnetics, advanced surface ship sonar,Renard, V., Schrumpf, B., and Sibuet, J.

In the First World War, Britain, as an island nation, was heavily dependent on foreign trade and imported resources. Germany found that their submarines, or U-boats, while of limited effectiveness against surface warships on their guard, were greatly effective against merchant ships, and could easily patrol the Atlantic even when Allied ships dominated the surface. By 1915, Germany was attempting to use submarines to maintain a naval blockade of Britain by sinking cargo ships, including many passenger vessels. Submarines, however, depending on stealth and incapable of withstanding a direct attack by a surface ship (possibly a Q-ship disguised as a merchant ship), found it difficult to give warning before attacking or to rescue survivors, which meant that civilian death tolls were high.

The Whitehead Mark 3 torpedo was a Whitehead torpedo adopted by the United States Navy for use in an anti-surface ship role after the E. W. Bliss Company of Brooklyn, New York secured manufacturing rights in 1892. The primary difference between the Mark 3 and the previous versions of the 3.55-meter Whiteheads was the inclusion of the Obry steering gyro for azimuth control. This device reduced the maximum deviation right or left of the target from 24 to 8 yards. About 100 Mark 3s were purchased from the E. W. Bliss Company; in 1913, these were redesignated Torpedo Type A. These were withdrawn from service use in 1922 when all torpedoes designed before the Bliss-Leavitt Mark 7 torpedo were condemned.

A keen yachtsman before the war, Young was appointed to the RNVR as a probationary sub-lieutenant on 12 April 1940 and underwent initial training at , the main RNVR shore establishment at Hove in Sussex. Volunteers were sought from suitable RNVR officers to join the submarine branch, Young volunteered with two others and after an interview and familiarisation trip on was accepted for service into submarines. Before reporting for submarine officer training at he was required to undertake a period of service on a surface ship, so Young joined on patrol in the North Sea. He was lucky in that both the commanding officer and First Lieutenant of Atherstone had served in submarines and were able to impart a lot of knowledge to Young.

It was expected that the Soviet Union would have its own SSN within a few years, as it had produced its own atomic bomb, hydrogen bomb, and advanced conventional submarines only a few years behind their development in other countries. As it turned out, the Soviet Navy was only three years behind the USN with their first nuclear-powered submarine. Various ASW technologies and weapons, including new surface ship and submarine sonars, SOSUS, ASROC, the Mark 45 nuclear torpedo, and "Stinger" (later SUBROC) were in development. Columbus Iselin II, director of WHOI, suggested to Admiral Burke that an inter-agency study was necessary to determine the best approach in each area, and probably also to improve coordination among the numerous offices pursuing the problem.

Paige and Odell discover that Tiger Shark mistook Fort James for the German submarine tender and sank the British ship; they also learn that Brice, Loomis, and Coors believed they could not afford this drastic mistake to appear on their records and conspired to suppress the story, killing Winters on the deck as he tried to save the survivors of Fort James. Tiger Shark is crippled by mounting accidents, and only five survivors remain: Brice, Odell, Paige, Stumbo (Jason Flemyng), and "Weird" Wally (Zach Galifianakis). Wally concludes the submarine is haunted by a "malediction" that must be satisfied to escape its netherworld between heaven and hell. After Tiger Shark arrives at the location of the sinking of Fort James and surfaces in a disabled condition, those aboard detect a surface ship nearby.

Especially when active capabilities are included, the array can be treated as a bistatic or multistatic sensor, and act as a synthetic aperture sonar (SAS) For ships that cooperate with aircraft, they will need a data link to sonobuoys and a sonobuoy signal processor, unless the aircraft has extensive processing capability and can send information that can be accepted directly by tactical computers and displays. Signal processors not only analyze the signals, but constantly track propagation conditions. The former is usually considered part of a particular sonar, but the US Navy has a separate propagation predictor called the AN/UYQ-25B(V) Sonar in situ Mode Assessment System (SIMAS) Echo Tracker Classifiers (ETC) are adjuncts, with a clear MASINT flavor, to existing surface ship sonars . ETC is an application of synthetic aperture sonar (SAS).

In the absence of this cooling effect, the dominant effect of changes to Arctic clouds is an increased trapping of infrared radiation from the surface. Ship emissions, mercury, aluminium, vanadium, manganese, and aerosol and ozone pollutants are many examples of the pollution that is affecting this atmosphere, but the smoke from forest fires is not a significant contributor."Previously some scientists had speculated that the sooty carbon in the arctic air was the product of natural forest fires, rather than industrial combustion. But a clever application of carbon isotope dating rules out that possibility," observes John Harte, The Green Fuse: an ecological odyssey 1993:19; fossil fuels are comparatively depleted in rare heavy carbon, which decays slowly to nitrogen, so that wildfire carbon is identifiable by its carbon fingerprint.

5 days for purposes of counting qualifying days. Qualifying days applied to the Navy Reserve Sea Service Deployment Ribbon may not be credited towards the Sea Service Deployment Ribbon or the Navy and Marine Corps Overseas Service Ribbon. For service prior to January 1, 2014, the former requirements still apply. Under those rules, the Naval Reserve Sea Service Ribbon was awarded to any member of the U.S. Navy Reserve (formerly U.S. Naval Reserve) who, while serving as a drilling Selected Reservist (SELRES) or a Training and Administration of the Reserve/Full Time Support (TAR/FTS) officer or sailor, completed twenty-four cumulative months of duty on board a U.S. Navy Reserve Force surface ship or assigned to a deployable/regularly deploying U.S. Navy Reserve Force Aviation Squadron (RESFORON).

The Type 1945 destroyer was designed in 1945, based upon the design of the Type 1936D and E destroyers, the plans for which were later accidentally destroyed by fire. They were designed during a time when Germany was prioritizing construction of submarines, with little to no effort going into her surface fleet, making the odds of the Type 1945 destroyers, or any other type of ship which was designed after 1942, being constructed, near zero. However, the Konstruktionsamt (Construction Department) continued to create designs for surface ships until the end of the war. Before the design was even created, Germany was restricting the use of her surface fleet; after the sinking of the German battleship Bismarck on 27 May 1941, heavy restrictions were placed upon surface ship commanders' tactical freedom.

The 3M-54 Kalibr, (Калибр, caliber), also referred to it as 3M54-1 Kalibr, 3M14 Biryuza (Бирюза, turqoise), (NATO codenames SS-N-27 Sizzler and SS-N-30A), 91R1, 91RT2 is a group of Russian surface ship-, submarine-launched and airborne anti-ship and coastal anti ship (AShM), land attack cruise missiles (LACM) and anti-submarine missiles developed by the Novator Design Bureau (OKB-8). Derived export versions are the 3M54E, 3M54E1, 3M14E, 91RE1, 91RTE2. The 3M54T, 3M54K, 3M54A, 3M54E (3M54TE), 3M54KE and 3M54AE have a second stage that performs a supersonic sprint in the terminal approach to the target, reducing the time that target's defense systems have to react. The 3M54T1, 3M54K1, 3M54A1, 3M54E1 (3M54T/K/AE1) only travel at subsonic speeds, although their range is accordingly greater than those of the supersonic versions.

After the war, all surviving Group One and Two boats were scrapped and the remainder fitted with snorts. In the late 1940s and 1950s, most were streamlined for quiet and higher-speed underwater operation against Soviet submarines, in place of the anti-surface-ship role that they had been designed for. In January 1948, it was formally acknowledged that the main operational function of the British submarine fleet would now be to intercept Soviet submarines slipping out of their bases in Northern Russia to attack British and Allied merchant vessels. The following April, the Assistant Chief of Naval Staff, Rear-Admiral Geoffrey Oliver, circulated a paper in which he proposed that British submarines take a more offensive role by attacking Soviet submarines off the Northern Russian coast and mining the waters in the area.

The Navy said the world threat picture had changed in such a way that it made more sense to build at least eight more Burkes, rather than DDG-1000s. The Navy concluded from fifteen classified intelligence reports that the DDG-1000s would be vulnerable to forms of missile attacks. Many Congressional subcommittee members questioned that the Navy completed such a sweeping re-evaluation of the world threat picture in just a few weeks, after spending some 13 years and $10 billion on the development of the surface ship program known as DD-21, then DD(X), and finally DDG-1000. Subsequently, Chief of Naval Operations Gary Roughead cited the need to provide area air defense and specific new threats such as ballistic missiles and the possession of anti-ship missiles by groups such as Hezbollah.

When first conceived in the late 1970s, the Type 23 was intended to be a light anti-submarine frigate to counter Soviet nuclear submarines operating in the North Atlantic. The Type 23 would be replacing the frigates (which had entered service in the 1960s) and the Type 21 frigate (a general purpose design that had recently entered service) as "the backbone of the Royal Navy's surface ship anti-submarine force". Although not intended to replace the Type 22 frigate, reductions in the size of the Navy due to the 1998 Strategic Defence Review led to HMS St Albans replacing , a Type 22 frigate. Overhead view of HMS Richmond in August 2013 The ships were intended to carry a towed array sonar to detect Soviet submarines in the North Atlantic and carry a Westland Lynx or EHI Merlin helicopter to attack them.

The ship's main gun armament was removed and replaced by a single QF 4-inch naval gun Mk XVI mount directed by a Simple Tachymetric Director, while close-in anti-aircraft armament consisted of five 40mm Bofors, with one twin Mk 5 mount amidships, and three single Mk 7 mounts on the bridge wings and on the ship's quarterdeck. Anti submarine armament consisted of two Squid ASW mortars, while a single quadruple 21-inch torpedo- tube mount was retained, giving an anti-surface ship capability, although the hoped for anti-submarine homing torpedoes failed to become available. A Type 293Q surface/air search radar and Type 974 navigation sonar was fitted, while the sonar outfit consisted of Type 146B search, Type 147P depth finder, Type 162 target classification and Type 174 Squid control. After completion of this refit, Paladin returned to reserve.

The DDAM simulates the interaction between the shock-loaded component and its fixed structure as the free motion of a naval vessel in water produces a higher shock spectrum than a heavy structure would when mounted to a terrestrial surface. The DDAM takes interaction into account in relation to the mass of the equipment, its mounting location, and the orientation of the equipment on the vessel. Engineers use finite element method analysis software to verify designs using DDAM computer simulations that model the known characteristics of underwater explosion phenomena as well as the surface ship or submarine body responses to shock loading and application of a shock spectra in order to apply the appropriate shock responses at the mountings of shipboard equipment (e.g., masts, propulsion shafts, rudders, rudderstocks, bearings, exhaust uptakes and other critical structures) due to underwater explosions.

"NEWPORT AND NAVY TORPEDOES - AN ENDURING LEGACY" It was succeeded by the problematic Mark 14 torpedo, but remained in service in S-boats and fleet submarines through the Pacific War.Blair, Clay, Jr. Silent Victory (Philadelphia: Lippincott, 1975). The Mark 10 featured the largest warhead ( of TNT) of any U.S. torpedo developed at that time. Stockpiles of Mark 10 Mod 3 torpedoes were used extensively during the first part of World War II due to short supply of the newer and longer ( Mark 14s, with some fleet submarines carrying a mixture of both types on patrol.United States Submarine Operations in World War II Mark 10 torpedoes, and those developed at the same time (Mark 9 air- and Mark 8 surface ship- launched) used essentially the same control package (the Ulan gear) as the newer Mark 14 for depth and direction.

During the 1982 Falklands War, Arrow was the first British ship to see action when she shelled Argentine positions around Port Stanley airfield on 1 May and the first to be hit by an Argentine Air Force aircraft, sustaining several cannon shell hits to her funnel uptake and one casualty from shell splinters.British ships lost or damaged - Battle Atlas of the Falklands War 1982 by Land, Sea and Air. NavalHistory.net On 2 May Arrow was assigned to a three-ship Surface Action Group against what was thought to be an Argentine surface ship south of East Falkland. The mission was aborted when the ship's navigator identified the target as a small island. On 4 May she assisted in extinguishing the fires and evacuating the crew of the Type 42 destroyer HMS Sheffield, which had been struck by an Exocet missile, rescuing 225 of the 261 surviving crew.

On 17 August 1977, NS Arktika ("Arctic") became the first surface ship ever to reach the North Pole. Arktika was withdrawn from service in 2008 after clocking up 175,000 hours of reactor operation time and covering more than 1 million nautical miles.Arktika rests after 33 years of icebreaking, World Nuclear News, 07 October 2008 Rather than be scrapped, there are calls for her to be converted to a museum ship, like her predecessor Lenin.“Arktika” could become museum, Barents Observer, August 17, 2012 NS Sibir ("Siberia") ceased operation in 1992 and is awaiting scrapping.Russia scraps three nuclear icebreakers, Barents Observer, January 26, 2012 The NS Rossiya ("Russia") carries two helicopters.

BRIDGE had purchased for the UK research fleet a Simrad multibeam echosounder for mapping the seafloor from a surface ship. To increase detail in any geographical areas of interest it also funded upgrades to the existing UK Towed Ocean Bottom Instrument (TOBI), which made 3D images of the seabed as it was towed 300m above the ocean floor. TOBI was modified to increase its resolution, to add a gyrocompass and to add a three component magnetometer for measuring the magnetic field of the seafloor rock over which it was towed. The BRIDGE Towed instrument (BRIDGET), was developed for hunting and studying the plumes of warm, mineral rich fluids rising into the water column from vent fields. This “hot-spring sniffer” was towed at depth behind a ship in areas where vent fields were suspected to occur and fed geochemical data back to the ship in real time.

At the verge of 1960, the U.S. Navy commissioned the George Washington as its first Ballistic Missile Submarine, making it the first VLS submarine in the world to use nuclear rather than diesel propulsion The Kara-class cruiser Azov was the first surface ship to be fitted with a VLS. The system in question contained 48 cells for 5V55RM missiles The VLS cells on board A Tomahawk missile canister being loaded into a VLS aboard the Arleigh Burke-class destroyer A vertical launching system (VLS) is an advanced system for holding and firing missiles on mobile naval platforms, such as surface ships and submarines. Each vertical launch system consists of a number of cells, which can hold one or more missiles ready for firing. Typically, each cell can hold a number of different types of missiles, allowing the ship flexibility to load the best set for any given mission.

With her training cycle complete, Crommelin departed Pearl Harbor on 24 August 1999 for a three- month deployment to the Eastern Pacific in support of counter narcotics operations. During this deployment, Crommelin steamed 77 of 92 days, flew more than 350 mishap-free SH-60B flight hours, and was a key player in four major cocaine seizures. Upon her return to Pearl Harbor on 24 November 1999, Crommelin immediately began the work up cycle for her next deployment with the battle group in August 2000. In February 2000, Crommelin was awarded the Battle "E" for Destroyer Squadron 31 as well as each of the four command excellence awards. Other accomplishments included the 1999 Commander in Chief, Pacific Fleet Retention Excellence Award, 1999, Commander, Naval Surface Forces Pacific (COMNAVSURFPAC) Surface Ship Safety Award, COMNAVSURFPAC Self- Sufficient Ship of the Quarter Award (Q4 FY99 and Q2 FY00), and the distinction of being the first Pearl Harbor ship to hoist the Enlisted Surface Warfare Specialist Pennant.

The depth charges caused serious flooding aboard the German submarine, , under the command of Joachim Schepke, and Schepke, fearing the submarine would sink, and hoping that he could torpedo the British destroyer, ordered U-100 to the surface. Vanoc spotted U-100 on the recently fitted but primitive Type 286M radar, the first confirmed British surface ship radar sighting of a U-boat, and rammed the German submarine, sinking her. Only six of U-100s crew, not including Schepke, survived. Shortly afterwards, U-99, which was trying to slip out of the convoy on the surface, spotted Walker and dived. Walker picked up U-99 on her sonar and attacked with depth charges, forcing the submarine to the surface. Vanoc spotted the surfaced U-99, and both destroyers opened fire on the stricken U-boat, which was scuttled by her crew as they abandoned ship.Blair Hitler's U-Boat War: The Hunters 1939–1942 1990, pp. 256–258.Brown 2007, pp. 76–77.

The types and controls over the collection of information, the communications systems may vary, but the task or mission of providing clarification of the situation and options to the commander remain the same whether the CIC is located on a submarine, surface ship, or airplane. Some control, assistance, and coordination functions may be delegated to the CIC staff or directly to the CIC officer, such as overseeing the mode and prioritization of sensor resources such as radar monitoring, targeting, or sonar activities; communications to external sources and assets. On US aircraft carriers this area is called the combat direction center (CDC). The United States developed their Command Information Center concept circa the winter of 1942-1943 and implemented it in a surge of refitting and retraining during 1943 after post- battle action analyses of battles in 1942 from the battle of the Coral Sea through the losses at Ironbottom Sound during the protracted Solomon Islands campaign.

Then from 13 January to 13 February, she took part in FLEETEX 2–92; followed by Exercise Fabric Falcon Brave form 26 February to 3 March. Comte de Grasse's superior performance was again recognized in March 1992 when she was awarded a second consecutive Battle Efficiency Award, representative of the best destroyer in Cruiser – Destroyer Group Eight. This prestigious award encompassed Mission Area Excellence Awards in Navigation and Deck Seamanship, Anti-Submarine Warfare (ASW), Anti-Surface Warfare (ASUW), Electronic Warfare (EW), Anti-Aircraft Warfare (AAW), Engineering, Damage Control, Surface Ship Safety, and Command Control and Communications. In preparation for her next deployment, Comte de Grasse completed Refresher Training in Guantánamo Bay, Cuba, conducted various battle group exercises in the Caribbean Sea, such as FLEETEX 2–92, and successfully passed a myriad of pre-deployment inspections and exercises, including a Combat Systems Assessment (CSA), in which Comte de Grasse received the highest grade of any unit in the entire U.S. Atlantic Fleet during 1991.

In a section from this 2014 book titled "The Danger of Culture," retired U.S. Navy Rear Admiral Dave Oliver offers the theory based on his own experiences that it was possibly a hydrogen explosion, either during or immediately following a battery charge, that destroyed USS Scorpion and killed her crew. The proximate cause in that scenario would have been the procedural carryover from diesel boat days wherein the boat was effectively rigged for collision—with subsequent changes in ventilation flow and watertight condition—before proceeding to periscope depth by way of setting "Condition Baker". Oliver had personally witnessed dangerously high percent-hydrogen spikes under such conditions aboard a nuclear submarine, specifically while going to periscope depth and setting Condition Baker during a battery charge. Diesel boats, in contrast, were not capable of doing a battery charge while deeply submerged, but were instead dealing with the risk of collision while on anti-surface ship operations when proceeding to periscope depth while in or near shipping lanes.

U-boat reports gave the impression that much shipping was moving between Lerwick and Bergen in Norway and the commander of the High Seas Fleet, () Admiral Reinhard Scheer, ordered an attack by surface ships. German bases to the south of the route made a surprise attack at the east end of the convoy route feasible; that the short days and stormy weather in the autumn and winter increased the possibility that a sortie could go unobserved was as obvious to the Imperial German Navy () as to the British. By forcing the British to reinforce the escorts of the Scandinavian convoy, a surface ship attack could help the wider U-boat campaign. The new, fast, minelaying light cruisers Brummer ( Max Leonhardi) and Bremse ( Siegfried Westerkamp), with a speed of , each armed with four naval guns and two (22-pounder) anti-aircraft guns, were chosen for an operation against the Scandinavian convoy and disguised to look like British C-class cruisers.

On 2 August 2013, the US Navy announced it was awarding a $212 million contract to General Dynamics Bath Iron Works to build a steel deckhouse for destroyer Lyndon B. Johnson (DDG-1002). The U.S. Naval Institute stated "the original design of the ship would have had a much smaller RCS, but cost considerations prompted the Navy over the last several years to make the trades in increasing RCS to save money..." To improve detection in non-combat situations by other vessels, such as traversing busy shipping channels or operating in inclement weather, the Navy is testing adding onboard reflectors to improve the design's radar visibility. The usefulness of the stealth features has been questioned. The class's role was to provide Naval Surface Fire Support, which requires the ship to be in typically crowded near-shore waters, where such large and distinctive ships can be tracked visually, and any surface ship becomes non- stealthy when it begins firing guns or missiles.

Though that laboratory had closed with the end of that war the same criteria and some of the same people advising made New London the logical place to site the East Coast laboratory in response to the Chief, Bureau of Ships, now Naval Sea Systems Command (NAVSEA), April 10, 1941 request to the National Defense Research Committee to establish both an East and West coast antisubmarine warfare research laboratory. On July 1, 1941 the New London laboratory's establishment got approval with management by Columbia University for a wide range of antisubmarine warfare work including, passive sonar, ocean acoustics and recording of underwater sounds for that work. In 1944 the Naval Research Laboratory (NRL) directed reorganization of the Underwater Sound Laboratory at New London for peacetime operation consolidating the Harvard Underwater Sound Laboratory, which had focused on physics of underwater sound, surface ship sonar and weapons systems, in Cambridge, Massachusetts with the New London laboratory. After recruiting scientists from both efforts the new Navy Underwater Sound Laboratory was established on March 1, 1945.

A Swedish source (A2) in Stockholm had told the British naval attaché that a surface ship operation would be mounted against the next convoy and by 8 September, the Admiralty could provide the escort commander a report on the positions of the twenty U-boats expected to attack the convoy and forecast that 65 torpedo- bombers (true figure 92) and 120 bombers were preparing the biggest torpedo attack on an Arctic convoy so far. On 8 September the convoy was joined by Scylla, with the FDE and the Avenger carrier group, which had waited until before sailing, to conserve fuel and took post around the convoy at the same time on 9 September; the Germans sent new search positions to the U-boats and this was passed to the convoy the next day. The Cruiser Covering Force had sailed independently to a position west of Bear Island and the group carrying supplies bound for the Norwegian weather station at Barentsburg was off Svalbard, using PQ 18 to divert the Luftwaffe. The battleships of the distant covering force had sailed from Seidisfiord towards Jan Mayen Island.

Sibir under construction at Baltic Shipyard, December 2018 The construction of the first Project22220 icebreaker began with a steel cutting ceremony on 1 November 2012. The keel of the lead ship of the class was laid on the slipway on 5 November 2013 and the vessel was launched on 16 June 2016. The vessel was named Arktika () after the first surface ship to reach the North Pole that was in service in 1975–2008. While initially scheduled for delivery by December 2017, the construction of the lead Project22220 icebreaker has fallen behind schedule due to problems related to the delivery of domestically-sourced components. Arktika began the first stage of sea trials in Gulf of Finland under diesel power on 12 December 2019 and returned to Saint Petersburg two days later. The final phase of sea trials, during which the vessel will be tested under nuclear power, commenced on 23 June. The keel of the second Project22220 icebreaker (which the Russians refer to as the "first serial ship" of the class) was laid on 26 May 2015. The icebreaker was launched as Sibir () on 22 September 2017.

After World War II, the main naval threat to most Western nations was confrontation with the Soviet Union. The Soviets ended the war with a small navy and took the route of asymmetric confrontation against Western surface ship superiority by investing heavily in submarines both for attack and later fielding submarine-launched missiles. Several nations who purchased British and US surplus light carriers were most easily able to accommodate slow-moving, less expensive, and easy-to-land anti- submarine aircraft from the 1960s forward, such as the S-2 Tracker, which flew from the decks of US, Canadian, Australian, Dutch, Argentine, and Brazilian carriers, or Alizé, which flew from French and Indian ships, allowing these ships to still remain useful especially in the framework of NATO even as newer fighter and strike aircraft were becoming too heavy for the equipment designed for World War II aircraft. Improvement in long-range shore-based patrol and conventional ship-based ASW helicopter capability combined with the increasing difficulty maintaining surplus WWII carriers led to most of these ships being retired or docked by smaller nations from the 1970s to the mid-1980s.

During the exercise, an improved surface ship sonar system that was installed in both of the destroyers attached to Carrier Strike Group Seven was used for the first time. Carrier Strike Group Seven entered the U.S. Fifth Fleet's area of responsibility (AOR) on 18 February 2006, and fleet commander Vice Admiral Patrick M. Walsh visited the strike group's flagship, the carrier Reagan, on 27 February 2006. VFA-115 (22 Feb 2006) Ronald Reagan and Charles de Gaulle (27 April 2006) On 22 February 2006, F/A-18E Super Hornets (pictured) assigned to Strike Fighter Attack Squadron 115 (VFA-115) became the first aircraft launched from the flight deck of USS Ronald Reagan to drop ordnance on enemy targets in support of Operation Iraqi Freedom. Carrier Air Wing Fourteen squadrons VFA-22, VFA-25, VFA-113, and VFA-115 were the first to deploy with F/A-18 Hornet strike fighters equipped with the Remotely Operated Video Enhanced Receiver (ROVER) system that allows ground forces, such as Joint terminal attack controllers (JTAC), to see what an aircraft or unmanned aerial vehicle (UAV) is seeing in real time by receiving images acquired by the aircraft's sensors on a laptop on the ground via video transfer with little time delay.
