How fast is the F-117 Nighthawk?

The F-117 is a high-subsonic aircraft, not a supersonic fighter. Lockheed Martin’s 2019 fact sheet gives that speed category without an exact Mach maximum. The USAF museum lists a maximum cruise speed of 684 mph (about 1,101 km/h). That cruise specification is not a certified top-speed record; a Mach-to-speed conversion also requires an atmospheric condition.

Overview and design

The F-117 was the first operational stealth aircraft, designed for precision attack. Its faceted shape and radar-absorbing materials reduced radar returns; stealth does not make an aircraft undetectable. Lockheed’s program history identifies Have Blue as the earlier demonstrator that led to the F-117, rather than another name for the production aircraft.

Operational history

The first F-117 flew in June 1981. Initial operational capability followed in October 1983, and the program was publicly acknowledged in 1988. Its combat debut came in Panama in December 1989; it later flew in the Gulf War and Operation Allied Force. One aircraft was lost in combat in 1999. The USAF retired the fleet from operational service in 2008.

Retirement did not end every flight. The 144th Fighter Wing’s September 2021 report records two F-117s visiting Fresno for training and describes limited research and training use. This dated report does not establish today’s active fleet size.

Armament

The F-117 carried weapons internally for precision ground attack. The USAF museum lists up to 5,000 lb of internal stores; the exact load depends on the mission.

Frequently Asked Questions

Can an F-117 fly faster than sound?

Its published speed category is high subsonic. The museum’s 684 mph figure is labelled maximum cruise speed; an exact maximum Mach number is not established by these sources.

How many F-117s were built?

Lockheed Martin records 64 aircraft: 59 production aircraft and five developmental prototypes. The earlier Have Blue demonstrators are a separate program.

Is the F-117 still in service?

It retired from operational service in 2008. Official reporting documents later research and training flights, including the September 2021 Fresno visit.
