The 6023d Radar Evaluation Squadron is an inactive United States Air Force unit. It was last assigned to the 41st Air Division, stationed at Naha Air Base, Okinawa. The unit was inactivated on 31 July 1960. History The unit's mission was to fly evaluation flights against new ground surveillance air defense radar installations. It also evaluated proposed radar (fixed and mobile) and perform intruder tests against operating Aircraft Control and Warning (AC&W) sites. It also provided training to ground radar sites. It was the last USAF operator of B-29 Superfortresses, and the unit at times had to curtail flights due to high out-of-commission rate of aircraft, which were supported by cannibalization of spare parts from non-flying aircraft kept in storage in the United States. Squadron inactivated in July 1960 after last USAF B-29 flight on 21 June 1960. Aircraft could no longer be reliably supported due to lack of logistics support.
