===U-2R/S details===
The U-2R, first flown in 1967, is significantly larger and more capable than the original aircraft. 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. The [[17th Reconnaissance Wing]], [[RAF Alconbury]], England used operational TR-1As from 1983 until 1991. The last U-2 and TR-1 aircraft were delivered to USAF in October 1989. In 1992 all TR-1s were re-designated to U-2R for uniformity across the fleet. The two-seat trainer variant of the TR-1, the ''TR-1B'', was redesignated as the ''TU-2R''. After upgrading with the GE F118-101 engine, the former U-2Rs were designated the ''U-2S'' ''Senior Year''.
