Since there is no photo available of the XB-53, the informa-
tion from Wright Patterson Air Force Museum offers a short
history of the bomber.
Quote:
"The Convair XB-53 was originally designed as an attack aircraft with the designation XA-44. The
aircraft was to have a 30 forward swept wing with an 8 dihedral. Convair engineers used forward
swept wing research data captured from Germany in WWII as the basis for the design. The wing
was mounted at the far aft portion of the fuselage and also served as the horizontal stabilizer. The
design had a conventional vertical stabilizer and rudder, but changes in pitch and roll were
accomplished with wing mounted control surfaces. The elevators were on the inboard wing while the
ailerons were outboard. The wingtips were also designed as variable incidence control surfaces.
The design called for three General Electric J35 turbojets of 4,000 lbs. thrust each mounted within the
fuselage. Estimates indicated as top speed of approximately 580 mph. Classified as a medium
bomber, the XB-53 would have carried up to 12,000 lbs. of bombs. It was also designed for 40 High
Velocity Aerial Rockets (HVAR) mounted on underwing pylons.

Convair diverted funding initially allotted to the XB-46 program to work on the XA-44/XB-53 project.
Two aircraft were ordered (S/N 45-59583/4) but neither aircraft were completed before the XB-53
program was canceled.
