Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The Lockheed XF-90 was built in response to a United States Air Force requirement for a long-range penetration fighter and bomber escort. The same requirement produced the McDonnell XF-88 Voodoo. Lockheed received a contract for two prototype XP-90s. The design was developed by Willis Hawkins and the Skunk Works team under Kelly Johnson. Two prototypes were built. Developmental and political difficulties delayed the first flight until 3 June 1949, with Chief Test Pilot Tony LeVier at the controls. Performance of the design was considered inadequate due to being underpowered, and the XF-90 never entered production. After a redesign from its original delta planform, the Lockheed Model 90 was built as a mock-up in 1947. The final design featured 35° sweptback wings, a sharply-pointed nose and two Westinghouse J34-WE-11 axial-flow turbojet engines, providing a total thrust of 6,200 lbf,mounted side-by-side in the rear fuselage and fed by side-mounted air intakes. The wings had leading-edge slats, Fowler flaps and ailerons on the trailing edge. The pressurized cockpit was fitted with an ejector seat and a bubble canopy.
