It’s Thursday, and Lockheed Week continues.
Here’s the XF-90, a penetration fighter that took its maiden flight in 1949. That’s just four years after the end of WWII, and look how far we’ve come from straight-wing prop fighters. The idea behind the penetration fighter was basically that of an escort, designed for long range and to defend bombers against enemy interceptors. Only two XF-90s were built.
