AN-71

The AN-71 aircraft was developed for accomplishment of the tactical missions related to early radar detection, tracking and guidance. It was created on the basis of the AN-72 transport airplane, whose aerodynamic configuration was modified to assure optimal conditions for operation of EWS system radar antennas. Principal characteristic feature of the AN-71 is a large disc-shaped rotating radome on the vertical tail tip. The carrier aircraft and the EWS system together made up the airborne early warning and control system. Prime contractor for the aircraft development was Kyiv Mechanical Works facility and for the EWS system – VEGA Association of Moscow. In addition to the military application, the AN-71 could also be used as a data retransmitter for air traffic control in the remote regions. A total of two AN-71 flying prototypes were built. Their testing demonstrated a capability to improve combat effectiveness of fighter aviation 2.5 to 3 times. After 1990, the program was frozen and later shut down in view of the lack of governmental funding; it was never reopened.
