F9F-2

F9F-3

Allison J33 powered version produced as insurance against the failure of the J42, 54 built. All converted to J42 power later.

XF9F-4

F9F-4

Version with longer fuselage with greater fuel load and powered by J33 engine. Most re-engined with J42s. F9F-4s were the first aircraft to successfully employ blown air, extracted from between the engine's compressor and combustion chambers, to energize the slot flaps, thus achieving a decrease in stalling speed of 9 kn for takeoff and 7 kn on power approach for landing.

F9F-5P

Unarmed photo-reconnaissance version, 36 built, longer nose.

F9F-5K

After the F9F Panther was withdrawn operational service, a number of F9F-5s were converted into unmanned target drone aircraft.
