The United States Navy, United States Coast Guard, and United States National Oceanic and Atmospheric Administration (NOAA) use a hull classification symbol to identify their ships by type and by individual ship within a type. The system is analogous to the pennant number system that the Royal Navy and other European and Commonwealth navies use.
The Los Angeles class of submarines are nuclear-powered fast attack submarines (SSN) in service with the United States Navy. Also known as the 688 class after the hull number of lead vessel USS Los Angeles (SSN-688), 62 were built from 1972 to 1996, the latter 23 to an improved 688i standard. As of 2022, 26 of the Los Angeles class remain in commission—more than any other class in the world—and they account for more than half of the U.S. Navy's 50 fast attack submarines.
The Ship-Submarine Recycling Program (SRP) is the process that the United States Navy uses to dispose of decommissioned nuclear vessels. SRP takes place only at the Puget Sound Naval Shipyard (PSNS) in Bremerton, Washington, but the preparations can begin elsewhere.
USS Glenard P. Lipscomb (SSN-685) was a unique nuclear-powered attack submarine of the United States Navy.
The Virginia class, or the SSN-774 class, is the latest class of nuclear-powered cruise missile fast-attack submarines in service with the United States Navy. Designed by General Dynamics Electric Boat (EB) and Huntington Ingalls Industries, the Virginia class incorporates the latest in stealth, intelligence gathering, and weapons systems.
The Gato class of submarines were built for the United States Navy and launched in 1941–1943. Named after the lead ship of the class, USS Gato, they were the first mass-production U.S. submarine class of World War II.
An attack submarine or hunter-killer submarine is a submarine specifically designed for the purpose of attacking and sinking other submarines, surface combatants and merchant vessels. In the Soviet and Russian navies they were and are called "multi-purpose submarines". They are also used to protect friendly surface combatants and missile submarines. Some attack subs are also armed with cruise missiles, increasing the scope of their potential missions to include land targets.
USS Barracuda (SSK-1/SST-3/SS-550), the lead ship of her class, was a submarine that was the third ship of the United States Navy to be named for the barracuda, a voracious, pike-like fish. Her keel was laid down on 1 July 1949 by the Electric Boat Division of General Dynamics Corporation in Groton, Connecticut. She was launched on 2 March 1951 as K-1, sponsored by Mrs. Willis Manning Thomas, and commissioned on 10 November 1951. Notably, future President of the United States Jimmy Carter served as an officer on K-1 as part of its pre-commissioning crew and during its first year of active service until he was reassigned on 16 October 1952.
A cruise missile submarine is a submarine that carries and launches cruise missiles as its primary armament. Missiles greatly enhance a vessel's ability to attack surface combatants and strike land targets, and although torpedoes are a more stealthy option, missiles give a much longer stand-off range, as well as the ability to engage multiple targets on different headings at the same time. Many cruise missile submarines retain the capability to deploy nuclear warheads on their missiles, but they are considered distinct from ballistic missile submarines due to the substantial differences between the two weapons systems' characteristics.
USS Tullibee (SSN-597), a unique submarine, was the second ship of the United States Navy to be named for the tullibee, any of several whitefishes of central and northern North America.
USS Bonita (SSK-3/SS-552), a Barracuda-class submarine, was the fourth ship of the United States Navy to be named for the bonito, a name applied to several types of fish, including the skipjack tuna,, the Atlantic bonito, the lesser amberjack, or the cobia. She was originally named USS K-3 (SSK-3).
USS Bass (SSK-2/SS-551), a Barracuda-class submarine, was the second ship of the United States Navy to be named for the bass, an edible, spiny-finned fish. She was originally named USS K-2 (SSK-2).
The Permit-class submarine was a class of nuclear-powered fast attack submarines in service with the United States Navy from the early 1960s until 1996. They were a significant improvement on the Skipjack class, with greatly improved sonar, diving depth, and silencing. They were the forerunners of all subsequent US Navy SSN designs. They served from the 1960s through to the early 1990s, when they were decommissioned due to age. They were followed by the Sturgeon and Los Angeles classes.
The Skipjack class was a class of United States Navy nuclear submarines (SSNs) that entered service in 1959-61. This class was named after its lead boat, USS Skipjack. The new class introduced the teardrop hull and the S5W reactor to U.S. nuclear submarines. The Skipjacks were the fastest U.S. nuclear submarines until the Los Angeles-class submarines, the first of which entered service in 1974.
A nuclear submarine is a submarine powered by a nuclear reactor, but not necessarily nuclear-armed. Nuclear submarines have considerable performance advantages over "conventional" submarines. Nuclear propulsion, being completely independent of air, frees the submarine from the need to surface frequently, as is necessary for conventional submarines. The large amount of power generated by a nuclear reactor allows nuclear submarines to operate at high speed for long periods, and the long interval between refuelings grants a range virtually unlimited, making the only limits on voyage times being imposed by such factors as the need to restock food or other consumables.
The Barracuda-class submarines were the product of Project Kayo, a research and development effort begun immediately after World War II by the United States Navy to "solve the problem of using submarines to attack and destroy enemy submarines." They originally had the hull classification symbol SSK, for "hunter-killer submarine".
An SSN is a nuclear-powered general-purpose attack submarine. SSN is the US Navy hull classification symbol for such vessels; the SS denotes a submarine and the N denotes nuclear power. The designation SSN is used for interoperability throughout NATO under STANAG 1166, though navies use other terms.
