The B-29B was a lightened, late-war version of the B-29 Superfortress, all 311 of which were built by the Bell factory in Atlanta. The type had only a tail turret for self-defence, as the other turrets were found to be redundant in the later stages of the war. The weight reduction allowed either a higher speed or a greater bomb load. This example was recovered in 1983 from the Army Proving Grounds in Aberdeen, Maryland. Sadly all records relating to its history were lost when it transferred to Army control in 1956 and as yet no information has been found on which units the aircraft served with, although most B-29B's served with the 315th Bombardment Wing in the Marianas in 1945. On display in the WW2 Hangar at Warner Robins Museum of Aviation. Georgia, USA.
