The Lockheed F-117 Nighthawk is a retired American single-seat, subsonic, twin-engined, stealth attack aircraft developed by Lockheed's secretive Skunk Works division and operated by the United States Air Force (USAF).

The Pratt & Whitney PW2000, also known by the military designation F117 and initially referred to as the JT10D, is a series of high-bypass turbofan aircraft engines with a thrust range from 37,000 to 43,000 lbf (160 to 190 kN).

Today’s F117 engine—the reduced temperature configuration (RTC)—uses technical and material advancements such as second-generation single-crystal turbine materials, improved cooling management and thermal barrier coatings to lower operating temperatures.

•The USAF officially retires the F-117 Nighthawk with a special flyover ceremony at Holloman AFB. (April 2008) Operational Missions Specs Length: 65 ft 11 in (20.09 m) Wingspan: 43 ft 4 in (13.21 m) Max Takeoff Weight: 52,500 lb (23,814 kg) Power Plant: 2 × General Electric F404 Engines Range: Unlimited with Aerial Refueling Wing Area: 780 ...

By the 1970s, new materials and techniques allowed engineers to design an aircraft with radar-evading or "stealth" qualities. The result was the F-117A, the world's first operational stealth aircraft.

2025年3月30日 · F-117, single-seat, twin-engine jet fighter-bomber built by the Lockheed Corporation (now part of the Lockheed Martin Corporation) for the U.S. Air Force. It was the first stealth aircraft—i.e., an aircraft designed entirely around the concept of evading detection by radar and other sensors.

2023年7月12日 · Pratt & Whitney's F117 engines have accumulated more than 17 million flight hours in support of military and humanitarian missions around the globe, be it airlift missions or overnight combat airdrops in unsecured locations.
