Boeing Skyfox Flight Concepts Skyfox
![]()
Skyfox N221SF first flew on August 23, 1983, piloted by Skip Holm or Tony LeVier, and has two externally mounted 16.4kN thrust Garrett TFE731 engines in place of the T-33’s single 20.5kN J33 turbojet. The forward fuselage is reprofiled in the absence of air intakes and faired into enlarged leading edge root extensions. Winglets are fitted in place of the T-33’s tip tanks, and internal fuel capacity is increased to compensate. A redesigned, enlarged empennage is fitted. The tandem cockpit is updated with modern avionics, equipment, and Stencel ejection seats. The resulting aircraft retains 70 per cent of the T-33’s original structure, including the wing and landing gear.
The rights to the Skyfox transferred to Boeing as Boeing Skyfox. The registration was cancelled in 1997.
