On February 24, 1947, the prototype XB-45 took its maiden flight from Muroc Army Air Field. 131 test flights in total were performed by three XB-45s; one was destroyed afterward and the other two were accepted by the United States Air Force on July 30 and August 31, 1948, respectively.

Compared to the XB-54, the B-45A version had upgraded ejector seats and improved communication equipment.
