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
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 XB-53 program was reinstated in February 1949 but only for a short while.
