The 193 operational Manchesters flew 1,269 sorties with Bomber Command, dropping 1,826 tons (1,657 tonnes) of bombs and lost 78 aircraft in action, flying its last operation against Bremen on 25 June 1942. A further 45 were non-operational losses of which 30 involved engine failure. The Manchester was withdrawn from operations in mid-1942 in favour of more capable aircraft. Its final role in RAF service was as instructional trainers for converting crews to the RAF's new Lancaster bombers; the Manchester and Lancaster shared nearly identical crew positions and fuselages. The type persisted in use for training purposes into 1943 before being completely retired.
