The Lockheed F-117 Nighthawk was the world's first operational aircraft designed around low observability, turning the Skunk Works' experimental stealth work into a single-seat, twin-engine precision attack aircraft. Developed in secrecy for the United States Air Force, the F-117A entered service in 1983, was publicly acknowledged in 1988, and became an enduring milestone in the history of aircraft design, flight testing, and operational stealth.
