Vickers Wellington
Conceived in the early 1930s to meet Air Ministry Specification B.9/32 (for what was then considered to be a heavy bomber) the Vickers Wellington formed the backbone of RAF Bomber Command until the 4 engined Lancasters and Halifaxes replaced it in that role in 1943. It was Wellingtons and Blenheims that made the first British bomber raids on German targets when 14 Wellingtons and 10 Blenheims attacked warships and Brunsbuttel; their crews encountered bad weather and heavy flak and two Wellingtons and four Blenheims failed to return. In 1942 the first of the 'thousand-bomber' raids occured, hitting Cologne on May 30th; and 599 of the bombers were Wellingtons. A Wellington Mk Ic was the first bomber to drop a 4,000lb 'blockbuster' or 'cookie' during a raid on Emden on April 1st, 1941. Wellingtons served in every theatre of the war, from the Atlantic, Coastal Command Wellington GR.Mk VIIIs, GR.Mk XIs and GR.Mk XIIs droping mines, depth charges and torpedoes on German targets from 1942 on, to the Far East where Wellington Mk Ics arrived in April 1942 and operated as the sole RAF 'heavy bomber' force in South East Asia until September 1944.
Wellington's suffered heavy losses in their initial daylight operations, but proved a success at night when night operations were approved. The Wellington would never operate over Europe in daylight after 1940.
Wellington crews liked the "Wimpy" because of its ablility to absorb tremendous damage and remain flying. It owed this capability to its unusual geodetic form of construction. Developed by Barnes Wallis, of bouncing bomb fame, for the Vickers Wellesley, the geodetic construction consisted of a diagonally fabricated lattice of alloy members to provide torsional and bending strength, the structure was fabric covered, thereby keeping weight to a minimum.
11,462 Wellingtons were produced, with the last Wellington trainers leaving RAF service in 1953.
