After the appearance of nuclear strategic submarines, it seemed that only other nuclear submarines could maneuver in three dimensions and maintain contact long enough to destroy them. Surface ships were at a clear disadvantage, since their sonar systems could not be operated as freely as submarines. This situation changed somewhat when surface warships began to tow passive sonar systems to submarine -like depths, giving homing torpedoes launched from ships and helicopters a better chance to lock on to targets and destroy them. Thus, both submarines and surface ships became effective anti-submarine weapons, but only submarines could operate close to enemy bases, where they could easily detect enemy submarines and ambush them, with little chance of being detected. For these reasons, it became inevitable that a navy with strategic nuclear submarines would also build attack nuclear submarines. Almost all modern nuclear attack submarines perform two basic functions: attacking enemy surface ...
