AN/APS-20

The AN/APS-20 was an airborne early warning, anti-submarine, maritime surveillance and weather radar developed in the United States in the 1940s. Entering service in 1945, it served for nearly half a century, finally being retired in 1991. Initially developed at Massachusetts Institute of Technology (MIT) under Project Cadillac, the radar was developed to be carried by aircraft to extend the sensor range of ships by placing a radar at altitude. Although developed for carrier-borne operation, first being installed in the single-engine General Motors TBM-3W Avenger, it was also used in larger four-engine airframes, the last being a fleet of Avro Shackleton AEW.2 which were converted from maritime patrol aircraft.
