The Convair XB-53 was a proposed jet-powered medium bomber aircraft, designed by Convair for the United States Army Air Forces.[1] With a radical tailless, forward-swept wing design, the aircraft appeared futuristic; however, the project was canceled before either of the two prototypes were completed.[1]

Design and development

The project was originally designated XA-44 in 1945 under the old "attack" category. An unusual forward-swept wing-design powered by three J35-GE turbojets, the project was developed in parallel with Convair's XB-46. It would have a wing with a 30° forward-sweep and 8° dihedral that was borrowed from German wartime research. The swept-forward configuration would give the aircraft a greater climb rate and maneuverability. It looked promising enough at one point for the Army Air Force to consider canceling the XB-46 in favor of the XA-44, since there was not enough funding for both.[1]

Classified as a medium bomber, the XB-53 would have carried up to 12,000 pounds of bombs as well as 40 High Velocity Aerial Rockets (HVAR) mounted on underwing pylons.[1]

Convair argued for completion of the XB-46 prototype as a flying testbed, without armament and other equipment, and with the substitution of two XA-44s for the other two B-46 airframes on contract. The Air Force ratified this in June 1946 but the project did not progress, nor were additional B-46s built. The XA-44 was redesignated XB-53 in 1948 when the "attack" category was dropped, but the project was canceled before the two prototypes were completed. The XA-44 program was reinstated in February 1949 but only for a short while.
