Since the performance of the first prototype was satisfactory it was decided to start production before the evaluation of either of the other prototypes. On 26 March 1918 the first production contract, for 150 aircraft, was issued; these were built at Vickers' works in Crayford in the Bexley. Production of the type by additional manufacturers was envisaged early on; in May 1918 follow-up contracts were issued to Clayton & Shuttleworth, Morgan & Co, and the Royal Aircraft Establishment (RAE), in addition to a separate production line at Vickers' Weybridge complex. At one point over 1,000 aircraft had been ordered under wartime contracts. The type had received the official name of "Vimy", after the Battle of Vimy Ridge.
