Important note: The “Nuclear” in “Nuclear attack submarine” means that it is powered by a nuclear reactor. It does not refer to its armament. An “attack” submarine means it is designed to attack ships and other submarines and these are typically not capable of carrying and launching ICBMs. Nuclear-armed deterrent submarines are called Ballistic Missile Submarines.
