The Lockheed F-117 Nighthawk was a highly classified, single-seat stealth attack aircraft designed and operated by the United States Air Force (USAF). It was the first operational aircraft to be designed around stealth technology, which made it virtually invisible to radar detection. The F-117 was used extensively during the Gulf War, where it was used to target key enemy installations and disrupt enemy communication lines. The aircraft was retired from active service in 2008, but its groundbreaking design and innovative technology have had a lasting impact on modern military aviation.
