Whitby: A “New Look” at Cold War Maritime Defense—The Royal Canadian Navy A “NEW LOOK” AT COLD WAR MARITIME DEFENSE The Royal Canadian Navy’s Seaward Defence Report and the Threat of the Missile-Firing Submarine, 1955 Michael Whitby ntisubmarine warfare (ASW) during the First and Second World Wars featured a relentless struggle of measure versus countermeasure as op- Aposing forces sought a decisive edge. Examples abound from both world wars: unrestricted submarine warfare bred convoys; surface attacks by submarines spawned Q-ships; hull-mounted sonar triggered night surface attacks by U-boats; the so-called Black Pit in the North Atlantic demanded very-long-range (VLR) patrol aircraft; acoustic homing torpedoes begot towed decoy noisemakers; and so forth.
