In 1954 Lockheed received approval to produce a high-altitude reconnaissance aircraft. The creation of this aircraft went to Lockheeds Skunk Works and the famous Kelly Johnson. The aircraft, a single-engine jet that could provide images day or night over Soviet territory, was labeled U-2 (U=utility) and given the name Dragon Lady. The first test flight took place in 1955 and was used by the CIA and the USAF during the Cold War. The U-2 came to international notoriety in 1960 when one piloted by Gary Power was shot down over the Soviet Union.
