F-90 (Blackhawk Comics) - F-90"B"

The F-90"B" was a fictional development of the Lockheed XF-90. Only two XF-90 prototypes were built, but the aircraft enjoyed an extensive (though fictional) operational life in the pages of Blackhawk comics. In the comics, however, the planes were always drawn as single-engined aircraft while the real XF-90 had two engines. To explain this difference and the obviously superior performance of the Blackhawks' jets in the comics, it has been proposed that the airplane in the comics was an upgraded model, the F-90B. The F-90B had the notoriously weak engines of the XF-90 replaced with a single, much more powerful engine designed by the Blackhawks.
