Boeing's Model 400 was designed to U.S. Navy requirements for a long-range carrier-based fighter bomber and a contract for three prototypes was placed with the company on May 4, 1943. The XF8B-1 designation indicated the primary fighting role of the new aircraft, but it was designed from the outset to carry an internal bomb-load of more than 3,000 lb, plus a similar external load, and had production ensued, a change of designation to one in the attack category would probably have been made. The first of the prototypes flew on November 27, 1944, and the Boeing type proved to be the largest and heaviest single-piston-engined fighter developed in the U.S.A. As with other Navy fighters, the wing outer panels folded upwards for carrier storage. The second and third prototypes were completed after the end of the war, by which time the need for the XF8B-1 had disappeared, and further development was soon discontinued.
