A nuclear submarine is a submarine powered by a nuclear reactor, but not necessarily nuclear-armed.In the US classification, nuclear-powered submarines are designated as SSxN, where the SS denotes submarine, x=G means that the submarine is equipped with guided missiles (usually cruise missiles), x=B means that the submarine is equipped with ballistic missiles (usually intercontinental) and the ...
Nuclear power would allow submarines to have greater accuracy and the ability to use torpedoes against ships, other submarines, and land targets. [11] In response to this the attack submarine became more important, particularly in regard to its postulated role as a hunter-killer. The US also used nuclear submarines as radar pickets for a while ...

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.
In the 67 years since the Navy launched the world's first nuclear-powered sub, USS Nautilus, its boats have only gotten more capable and more deadly.
The nuclear submarine is part of America’s so-called “nuclear triad” of atomic weapons — which also includes land-based ballistic missiles and nuclear bombs aboard strategic bombers.
Only the United States Navy, the Royal Navy of the United Kingdom, and France's Marine Nationale field an all-nuclear submarine force. By 1989, there were over 400 nuclear-powered submarines operational or being built. [6] Some 250 of these submarines have now been scrapped and some on order cancelled, due to weapons reduction programs.
U.S. Navy Submarine Force Pacific describes the nuclear-powered Ohio-class SSGNs and the USS Ohio as a critical tool to "project power and provide forward presence" and a "key component of our ...
