Douglas B-66 Destroyer

The Douglas B-66 Destroyer was a Tactical Air Command light bomber based on the United States Navy A3D Skywarrior. It was intended to replace the Douglas A-26 Invader. An RB-66 photo-reconnaissance version was ordered simultaneously and their airframes became the basis for the EB-66 electronic-warfare variant. 

Deliveries to the United States Air Force (USAF) began in 1956 with 145 of this model were produced. RB-66s were used as the major night photo-reconnaissance aircraft of the USAF during this period. 72 of the B-66B bomber version were built, 69 fewer than originally planned. Thirteen B-66B aircraft later were modified into EB-66B electronic countermeasures aircraft for the Vietnam War. Unlike the US Navy A-3 Skywarrior, which performed some bombing missions, the Destroyer was not used as a bomber in Vietnam. 

The RB-66C was a specialized electronic reconnaissance and ECM aircraft with a crew of seven; 36 of these aircraft were built with the additional crewmembers housed in what was the camera/bomb bay of other variants. RB-66C aircraft had distinctive wingtip pods and were used in the vcinity of Cuba during the Cuban Missile Crisis and later over Vietnam. In 1966, they were redesignated EB-66C. 

The final B-66 variant was the WB-66D weather reconnaissance aircraft, 36 of which were constructed. 

The EB-66C/E was removed from USAF service by 1973 and most examples either scrapped in place or placed in storage for eventual scrapping.
