This color, Cold War era recruiting film is about the U.S. Navy and their tactics in locating enemy submarines. Anti-submarine warfare (ASW) is a branch of underwater warfare that uses surface warships, aircraft, submarines, or other platforms, to find, track, and deter, damage, and/or destroy enemy submarines. Copyright is 1969. Featured in the film is footage of P-3 Orion search aircraft, DASH drone helicopter, and the venerable aircraft carrier USS Yorktown (CV-10), as well as destroyers USS Leary (DD-879), USS Walker (DD-517), USS Bridger (DE-1024) and various submarines including USS Scorpion (SSN-589). Also features footage of Norfolk, Virginia and Pearl Harbor, Hawaii.
