Anti-submarine Warfare is hard. Hard now and hard back in the late 60's when the Soviet sub force was big.
Shows the Navy's anti-submarine patrol in action during the late 1960s. Featuring flight operations off the aircraft carrier USS Wasp (CV-18), fixed wing and rotary wing aircraft perform sweeps of the sea in the vicinity of the fleet main body. They are joined by destroyers and other warships equipped with sonar, depth-charges and ASW torpedoes. The Grumman S-2 Tracker aircraft is especially featured.
