The Convair XB-53 was a stillborn jet bomber project by Convair for the United States Army Air Force. Originally, it was designated XA-44 in 1945 under the old "attack" category. An unusual forward-swept wing-design powered by three J35 turbojets, the project was developed in parallel with Convair's XB-46. It would have a German-derived wing with a 30° forward sweep and 8° dihedral. It looked promising enough at one point for the Army Air Force to consider cancelling the XB-46 in favor of the XA-44 since there was not enough funding for both. Convair argued for completion of the XB-46 prototype as a flying testbed and 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 cancelled before the two prototypes were completed. The XA-44 program was reinstated in February 1949 but only for a short while.
