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 cancelled 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.
