Locations of U-2s


*Note: TR-1A and B(Trainer) were redesignated in Oct 1991 to U-2R and U-2RT(Trainer); There is no outward appearance difference between a TR-1A and a U-2R, the difference lies in the sensor capability. The U-2R can carry more varied sensors. All aircraft built as TR-1s will be modified to U-2R capabilities.

*All U-2s will be converted to "S" specifications by 1998
