Lockheed U-2S

24 aircraft

The Lockheed U-2, America's most enduring spy plane, revolutionized high-altitude reconnaissance during the Cold War and remains operational today. First flown on July 29, 1955, it is a single-engine, high-wing monoplane designed to carry one pilot and sophisticated surveillance equipment to extreme altitudes. With its distinctive glider-like 103-foot wingspan and ability to reach altitudes exceeding 80,000 feet, the U-2 was manufactured by Lockheed's legendary Skunk Works division.
