The Lockheed U-2, nicknamed Dragon Lady, is a single-engine, high-altitude aircraft flown by the United States Air Force and previously flown by the Central Intelligence Agency. It provides day and night, high-altitude (70,000 ft, 21,000 m plus), all-weather surveillance. The aircraft is also used for electronic sensor research and development, satellite calibration, and satellite data validation.
A tactical reconnaissance version, the TR-1A, first flew in August 1981. A distinguishing feature of these aircraft is the addition of a large instrumentation "superpod" under each wing. Designed for standoff tactical reconnaissance in Europe, the TR-1A was structurally identical to the U-2R.
