Boeing XP-15 / XF5B-1
|FIGHTER||Virtual Aircraft Museum / USA / Boeing|
During the course of 1929, work began as a private venture on two prototypes of a single-seat parasol fighter monoplane, one of these prototypes (Model 202) being intended for offer to the USAAC and the other (Model 205) having arrester gear for US Navy evaluation. The Models 202 and 205 featured a semi-monocoque metal fuselage and metal wings, with smooth, non-stressed metal skinning. Provision was made for the standard twin 7.62mm gun armament and the Model 205 could carry a single 227kg bomb or five 13kg bombs. The Model 202 had a Pratt & Whitney SR-1340D Wasp rated at 450hp at 2438m and the Model 205 had an SR-1340C rated at 480hp at sea level. The Model 202 was flown in January 1930, and was unofficially assigned the designation XP-15 when evaluated by the USAAC. During evaluation it was fitted with a ring cowling and revised vertical tail surfaces, but was rejected by the USAAC and eventually crashed on 7 February 1931. The similar Model 205 was assigned the designation XF5B-1, and underwent modifications identical to those applied to the Model 202. Flown in February 1930, the XF5B-1 was used for experimental purposes for three years, no production being undertaken.
