Douglas
B-66 Destroyer

The Douglas B-66 Destroyer is a light bomber that was designed and produced by the American aviation manufacturer Douglas Aircraft Company. The B-66 was developed for the United States Air Force (USAF) and is derivative of the United States Navy's A-3 Skywarrior, a heavy carrier-based attack aircraft. Officials intended for the aircraft to be a simple development of the earlier A-3, taking advantage of being strictly land-based to dispense with unnecessary naval features. Due to the USAF producing extensive and substantially divergent requirements, it became necessary to make considerable alterations to the design, leading to a substantial proportion of the B-66 being original.

During 1956, deliveries to the USAF commenced. A total of 145 RB-66Bs would be produced. In service, the RB-66 would function as the primary night photo-reconnaissance aircraft of the USAF during this period; accordingly, many examples served with tactical reconnaissance squadrons based overseas, typically being stationed in the United Kingdom and West Germany. A total of 72 of the B-66B bomber version were built, 69 fewer aircraft than had been originally planned. A total of 13 B-66B aircraft later were modified into EB-66B electronic countermeasures (ECM) aircraft, which played a forward role in the Cold War between the United States and the Soviet Union, and were stationed at RAF Chelveston with the 42nd Tactical Reconnaissance Squadron, who performed the conversion during the early 1960s. They would rotate out of an alert pad in France during the time that the 42nd had them.
