BV256 was converted to a transport by BOAC and allocated the civil registration of G-AGFK in November 1942. It operated with the airline out of Asmara in modern day Eritrea. In August 1943 BV256 was returned to the RAF which operated it for a year with 525 Sqn. The Warwicks were replaced by Douglas Dakotas and scrapped. Photo from: Imperial War Museums

First production aircraft. 150 B.1 bombers were initially ordered but ongoing problems resulted in only 16 being built as bombers, all of which were used for testing. Of the rest of the order, some were delivered as transports or others for air-sea rescue. Photo from: Imperial War Museums

HF971 joined the Air Sea Rescue Training Unit at Thornaby, Yorkshire, after which it served successively with No. 292 Squadron RAF, No. 1 Air Sea Rescue Flight (Far East) and No. 1346 Air Sea Rescue Flight in Ceylon. Imperial War Museums

The Warwick C3's were used by the RAF as transport aircraft. 100 C3 frames were built. In 1946, this particular aircraft was fitted with Sabre VI engines and serving as an engine test-bed. Photo from Vickers

Another shot of this maritime patrol Warwick. The large Leigh searchlight had been made retractable, necessitating the removal of the dorsal gun turret. As in the Wellington, the windows revealed the geodetic framework which was already obsolete. Photo from: Nederlands Instituut voor Militaire Historie

The Warwick was developed from the Wellington, retaining the geodetic construction. It never saw action as a bomber but was used in maritime roles. The GR Mk V had a retractable Leigh Light in the rear fuselage. This aircraft, LM818, had its radar dome moved from the belly into a chin position.
