The United States Air Force continues to operate a mix of modern and legacy aircraft, including the Lockheed U-2 'Dragon Lady.' This high-altitude reconnaissance aircraft has been in service since the 1950s and remains the oldest active aircraft in the Air Force's inventory. Developed by Lockheed’s Skunk Works division, the U-2 was designed to fly above enemy air defenses for intelligence gathering during the Cold War.
Initially met with skepticism from the Air Force, the Central Intelligence Agency recognized its potential. Under Director Allen Dulles, a covert project named AQUATONE approved its design. The first U-2 units were delivered in 1955, and by 1956, they were officially introduced into service. Its nickname 'Dragon Lady' emerged due to its demanding flight characteristics and operational secrecy.
The U-2 is unique for its ability to operate at altitudes exceeding 70,000 feet, keeping it out of reach of most air defenses at that time. It can cover over 7,000 miles without refueling and often conducts missions lasting more than ten hours. Over the years, it has been powered by various engines, with current models using General Electric F118 turbofans.
