FAIREY SWORDFISH - The prototype of the Fairey Swordfish torpedo-spotter-reconnaissance aircraft for the Fleet Air Arm was developed under the direction of Marcel Lobelle to meet the requirements of Specification S.I5/33. Known as the Fairey TSR.II, it was a derivative of the earlier TSR.I and, first flown on April 17, 1934, was powered by a 690 hp Pegasus IIIM3. Three develop-ment aircraft were ordered in May 1935 to Specification S.38/34 and production was authorised at the same time. The Fairey Swordfish carried three crew for reconnaissance or two for torpedo duties, could operate as a floatplane and carried one 18 -in (46-cm), 1,610-lb (731-kg) torpedo or 1,500-lb (681-kg) mine under the fuselage or up to 1,500-lb (681-kg) of assorted bombs under fuselage and wings; other armament comprised one forward-firing and one free-mounted aft 0.303-in (7.7-mm) gun. First flight of a development aircraft was on December 31, 1935, the other two following in 1936, one on floats.
   Fairey Swordfish I: Initial production contract placed April 1935 for 86 aircraft, increased by subsequent contracts to 989 of which 300 were built by Blackburn at Sherburn-in-Elmet (sometimes i. own colloquially as 'Blackfish') and the remainder by Fairey. Deliveries bigan mid-1936 to No 825 Squadron, and 12 more squadrons equipped by September 1939; 13 more front-line FAA units were equipped by June 1943, and more than 20 second-line units used Fairey Swordfish for training and other duties. Operational use included gun-spotting, minelaying and torpedo attacks (notably at Taranto, when a complete Italian fleet was virtually eliminated, and on the battleships Schamhorst, Gneisenau and Prinz Eugen in the English Channel).
   Fairey Swordfish II: Improved version of Mk I with Pegasus IIIM3 or 775 hp Pegasus 30 engine, introduced 1943, with metal covered undersurfaces of lower wings to permit carriage and launching of eight 60-lb (27-kg) rocket projectiles. 1,080 built by Blackburn, of which 99 to Canada (some post-war) for RCAF and RCN. First successful operational use of RPs from Fairey Swordfish on May 23, 1943, by No 819 Sqn, sinking a U-boat. Also used by two RAF squadrons until May 1945.
   Fairey Swordfish III: As Mk II with ASV Mk X air-to-surface-vessel radar in large radome between undercarriage legs. 320 built by Blackburn, final delivery August 18, 1944. Operational, alongside Fairey Swordfish Us, with several FAA front-line squadrons up to May 1945, aboard mer-chant aircraft carriers, escort carriers and from shore bases.
   Fairey Swordfish IV: Some Fairey Swordfish IIs converted in Canada to have enclosed and heated cockpits. The designation was not officially confirmed.
   Addition from James Dickson, Corbeil, Ontario, Canada at January 06, 2005: it was a Swordfish torpedo attack which hit the Bismark and damaged her steering to the point where the British warships were able to move in and finish her off.
