Variants
XF9F-2
Prototypes, two built
F9F-2
First production version, powered by Pratt & Whitney J42 engine.

F9F-4
Version with longer fuselage with greater fuel load and powered by J33 engine.
F9F-4s were the first aircraft to successfully employ pressurized bleed air, tapped from the engine’s compressor stages, and blown across the surface of the slot flaps, simulating a higher airspeed across the control surface, and thus achieving a decrease in stalling speed of 9 kn for take-off and 7 kn on power approach for landing; re-designated F-9C in 1962, 109 ordered, all completed as F9F-5s.

Variant of F9F-4, but powered by Pratt & Whitney J48 engine.
Re-designated F-9D in 1962.
