The most mass produced bomber of the Second World War.

The twin engine Vickers Wellington medium bomber was designed against specification B.9/32 with the first prototype (K4049) being flown at Brooklands on 15th June 1936.
Designed by Vickers-Armstrongs Chief Designer Rex Pierson, utilising the geodetic construction methods devised by Barnes Wallace and used in the earlier Wellesley, the twin-engine Wellington continued to serve with distinction throughout World War II despite eventually being superseded in its primary role by the much larger, 'heavy bombers' such as the Avro Lancaster and the Vickers Warwick.

'The Wellie' was to bear the brunt of the Bomber Command offensive against Germany making up some 60% of the numbers in the first 1,000 bomber raid on 30th May 1942. The type also served with distinction with Coastal and Overseas Commands throughout the War on marine reconnaissance and anti-submarine duties.
The robust nature of its revolutionary construction paid real dividends in terms of both aircraft and lives saved throughout the night bombing campaigns.  one Vickers Wellington (LN514) became the subject of a Ministry of Aviation propaganda newsreel in October 1943 when it was constructed in just 23 hours 50 minutes by workers at the Broughton Factory which now produces wings for Airbus.

11,461 Wellingtons were built at Weybridge (Brooklands), Chester (Broughton) and Blackpool (Fylde).
The type also made a notable contribution post-war during the flight testing of new turbojet and turboprop engines as well as being the basis of the initial design of the VC-1 Viking of which the first 19 Viking 1A retaining the fabric covered geodetic wings of its illustrious parent.
The Wellington was finally retired in March 1953.
