variants with their own articles =The Blackburn B-5 Baffin torpedo bomber was a development of the Blackburn Ripon, the chief change being that a 545 hp Bristol Pegasus I.MS radial replaced the Ripon's Napier Lion water-cooled inline engine.

The Baffin was designed by Major F A Bumpus to meet a Fleet Air Arm requirement as a conventional two-seat single-bay biplane of mixed metal and wooden construction with fabric covering. It had swept, staggered, equal-span wings, the lower having an inverse gull to provide clearance for the torpedo while retaining a short undercarriage. Armament comprised one fixed forward-firing 0.303-in (7.7-mm) Vickers machine gun and one free-mounted Lewis gun in rear cockpit, plus one 2,000-lb (908 kg) bomb, or 1,576-lb (716-kg) Mk VIII or Mk IX torpedo, or three 530-lb (241-kg) or six 250-lb (114-kg) bombs.

Development

The Baffin first flew on 30 September 1932, and production began in 1933. Initial orders were placed for 29 new-build aircraft and 42 conversions of Ripon airframes. A further 26 conversions of Ripons into Baffins were ordered in 1935 because of reliability problems associated with the Armstrong Siddeley Tiger engines powering Blackburn Sharks, and the desire to expand the strength of the Fleet Air Arm. The last three new production Baffins had the 580 hp Pegasus II.M3 engine and were termed the Baffin T8A.

The aircraft is said to have inspired the coining of the word "Boffin".

ervice

Two prototypes and 33 production Baffins went to a training flight at Gosport for dummy deck-landing and torpedo practice, with the first Squadron re-equipping with the Baffin No 812 Squadron, in January 1934. The type went to sea with 810 Squadron on HMS "Courageous", 811 on HMS "Furious", 812 on HMS "Glorious" and HMS "Eagle" and 820 Squadron on HMS "Courageous". In addition 14 were sent to Malta to serve on carriers in the Mediterranean. The Baffin served barely two years before being replaced by the Blackburn Shark and Fairey Swordfish, with 812 Squadron continuing to fly Baffins until December 1936. All British aircraft appear to have been withdrawn from service before the outbreak of World War II.

In 1937 New Zealand acquired 29 of the best condition Baffins from the UK to equip Territorial Air Force (reserve) squadrons in Auckland, Wellington and Christchurch. Twenty-four were operational on the outbreak of war, 16 in Wellington and eight in Christchurch. On the outbreak of war these aircraft were utilised as trainers. With the realisation of the threat posed by surface raiders, the RNZAF Baffin was returned to the active list, the survivors being merged in March 1940 as the NZ General Reconnaissance Squadron, renamed 1 GR Squadron in 1941 when half the strength was transferred to 3 GR Squadron. The Baffins were replaced by Lockheed Hudsons before the outbreak of war with Japan; the last Baffins were broken up at Rongotai in 1941.
