Submarines in the United States Navy : ウィキペディア英語版 | Submarines in the United States Navy
There are three major types of submarines in the United States Navy: ballistic missile submarines, attack submarines and cruise missile submarines. In the U.S. Navy, all combatant submarines are nuclear-powered. Ballistic subs have a single, strategic mission: carrying nuclear submarine-launched ballistic missiles. Attack submarines have several tactical missions, including sinking ships and subs, launching cruise missiles, and gathering intelligence. == History == The submarine has a long history in the United States, beginning with the ''Turtle'', the world's first submersible with a documented record of use in combat.〔 *〕
