COMMENT: From the logistical point of view the US Navy was most interested to have only one type of aircraft on board its carriers for all operational tasks. An excellent design for all these duties was the Boeing XF8B, a new class of “five-in-one fighter” (fighter, interceptor, dive bomber, torpedo bomber, or level bomber). Designed around a new designed “power egg”, the Pratt & Whitney XR-4360 with 3,000hp this aircraft embodied a number of innovative features in order to accomplish the various roles. Three prototypes were ordered, but despite its formidable capabilities, with the end of the hostilities in the Pacific area the XF8B-1 was fated to never enter series production.
