The Ryan XF2R Dark Shark was an American experimental aircraft built for the United States Navy that combined turboprop and turbojet propulsion. It was based on Ryan Aeronautical's earlier FR Fireball, but replaced the Fireball's piston engine with a turboprop engine.

Design and development

The XF2R Dark Shark was based on Ryan Aeronautical's earlier FR Fireball, but replaced the Fireball's piston engine with a General Electric T31 turboprop engine driving a 4-bladed Hamilton Standard propeller. The turboprop made for much improved performance over the Fireball, and Ryan proposed the XF2R-2 to use a Westinghouse J34 turbojet in place of the General Electric J31 used as the auxiliary turbojet for the XF2R-1. The XF2R-2 also had a squared-off vertical stabilizer and jet intakes moved to the sides of the forward fuselage with NACA ducts instead of the inlets in the wing leading edge for the XF2R-1.

Although the Dark Shark proved to be a capable aircraft, it never progressed beyond the prototype stage and the XF2R-2 was canceled without being built because the Navy had abandoned the idea of the combination fighter and was instead looking into all-jet fighters, which it considered superior.
