The B-57 was the U.S. version of the English Electric Canberra which first flew on 13 May 1949 and was produced for the Royal Air Force in large numbers. The first Martin-produced USAF B-57 made its initial flight on 20 July 1953. By the time production was completed in 1959, a total of 403 planes had been built for the USAF, 67 of which were RB-57As designed for night photo reconnaissance and day combat mapping. The 'A' model B-57 was the only variant to retain the 'goldfish bowl' style canopy identical to the RAF variants. The aircraft on display was acquired from the US Army Proving Grounds in Aberdeen, Maryland in 1983. Its last duty station was with the 190th Tactical Reconnaissance Group, Air National Guard at Forbes ANGB, Kansas before it was retired to Aberdeen in 1972. Full serial 52-1475 (incorrectly marked as '457' instead of '475'). c/n 058. On display at the Warner Robins Museum of Aviation. Georgia, USA. 18-4-2013
