* F-35A (conventional takeoff and landing): Mach 1.6 (1,200 mph, 1,931 km/h)
* F-35B (short takeoff/vertical landing): Mach 1.6 (1,200 mph, 1,931 km/h)
* F-35C (carrier-based): Mach 1.8 (1,350 mph, 2,173 km/h)
These figures are for supersonic flight at high altitude. At sea level, the F-35's maximum speed is limited by the speed of sound, which is approximately 767 mph (1,235 km/h).
