The YF-93A was originally the F-86C but was redesignated after extensive design changes needed to prepare the aircraft for the USAF "Penetration Fighter" competition. The McDonnell XF-88 and Lockheed XF-90 were also evaluated, but the USAF never acquired a Penetration Fighter. A contract for 118 production F-93As was signed, but it was canceled before any aircraft were built.
The standard F-86 engine air inlet was changed on the first prototype (S/N 48-317) to two flush mounted fuselage inlets to make room for avionics and to further streamline the aircraft for increased range. The second aircraft (S/N 48-318), however, was completed with conventional engine air intakes. Both aircraft had unusual two-wheel main landing gear struts to support the increased weight caused by the large fuel load carried. Both prototype aircraft were used as test platforms by NACA before being declared surplus and scrapped.
