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". [ 1 ]
The Virginia class, or the SSN-774 class, is the newest class of nuclear-powered cruise missile fast attack submarines in service with the United States Navy.The class is designed for a broad spectrum of open-ocean and littoral missions, including anti-submarine warfare and intelligence gathering operations. [10]
Submarines of this class are named after American towns and cities, such as Albany, New York; Los Angeles, California; and Tucson, Arizona, with the exception of USS Hyman G. Rickover, named for the "father of the nuclear Navy." This was a change from traditionally naming attack submarines after marine animals, such as USS Seawolf or USS Shark ...
There are three major types of submarines in the United States Navy: ballistic missile submarines, attack submarines, and cruise missile submarines. All submarines currently in the U.S. Navy are nuclear-powered. Ballistic missile submarines have a single strategic mission of carrying nuclear submarine-launched ballistic missiles.
Prototype "fleet submarines"—submarines fast enough (21 knots (11 m/s)) to travel with battleships. Twice the size of any concurrent or past U.S. submarine. A poor tandem engine design caused the boats to be decommissioned by 1923 and scrapped in 1930.
The Alfa class, Soviet designation Project 705 Lira (Russian: Лира, meaning "Lyre", NATO reporting name Alfa), was a class of nuclear-powered attack submarines in service with the Soviet Navy from 1971 into the early 1990s, with one serving in the Russian Navy until 1996.
The SSN(X) or Next-Generation Attack Submarine program of the United States Navy aims to develop a new class of nuclear-powered attack submarines to succeed the Virginia and Seawolf classes. The SSN(X) program remains in the early stages of development and no official details have been released about its design or capabilities.
The Attack-class submarine was a planned class of French-designed submarines for the Royal Australian Navy (RAN), expected to enter service in the early 2030s with construction extending until 2050. [4] The project, which would have replaced the Collins-class submarines, began in 2007 as the Future Submarine program.
