Summary:Navy Instructional film on the role of the Medium-range Anti-submarine Torpedo Carrying Helicopter (MATCH) in co-ordinated anti-submarine warfare (ASW) operations. The film uses stock footage of German U-boat attacks on allied convoys during the Battle of the Atlantic, and various shots of Soviet submarines, to emphasise the importance of ASW. A Royal Navy Wasp helicopter, launched from the Leander Class frigate HMS Achilles (F.12) then carries out an attack on a submarine using air-dropped torpedoes, with direction from the parent ship's operations room, including computer plotting. The Wasp is then re-armed and scrambled to make another attack. The roles of the RAF's Nimrod long-range maritime patrol aircraft and the dipping-sonar equipped Sea King helicopter are also described.
