The Vickers Type 287 Wellesley was a general purpose bomber used by Great Britain during World War 2
The Type 287 was originally built by the company as a private venture, in order to replace the humdrum biplane they had originally submitted to meet Specification G.4/31, with the monoplane employing an alternative design of monoplane conﬁguration based on extensive use of light alloy geodetic construction developed by Barnes N. Wallis. When tested by the RAF, the monoplane proved far superior to the biplane and, as a result, in September 1935 an initial order was placed for 96 of these monoplanes with the name Type 281 Wellesley.
When production of the definitive Type 287 Wellesley Mk I ended in May 1938 a total of 176 had been built, and the type ﬁrst entered RAF service with No. 76 Sqn in April 1937. The Wellesley became well known in 1938 when, used by the RAF Long-Range Development Flight, two of three Type 292 aircraft (Pegasus XXII) led by Squadron Leader R. Kellett completed successfully a nonstop 7,158.40-mile (11520.40 km) flight from lsmailia, Egypt, to Darwin, Australia; this established a world absolute distance record that remained unbroken until 1945.
By the outbreak of World War ll some 100 Wellesleys remained in RAF service in the Middle East, being used operationally against Italian forces at a later stage and remaining in use for maritime patrol until 1941. Other Wellesley models were the Type 289 testbed for the Hercules HE15 radial, the Type 291 blind-flying model, the Type 294 with strengthened wing and Type 402 experimental three-seater.
