Remarks: Begun as a development of the Navy A3D Skywarrior in 1952 and bearing a superficial resemblance to the Skywarrior, the B-66 is actually a very different aircraft. The Destroyer was eventually built in several versions; bomber, photographic reconnaissance, weather reconnaissance, and electronic warfare. The WB-66 weather reconnaissance version was intended to gather weather data over battlefields and had the bomb bay replaced by a pressurized compartment for two weather equipment operations and their equipment. The WB-66D was the last version of the Destroyer built with 36 constructed between June 1957 and June 1958.
Remarks: The B-57 is one of only two major combat aircraft of foreign design adopted for use by the United States military since the end of World War II. The first British built Canberra arrived in the United States in 1951 and U.S. built aircraft began flying two years later. The B-57E version of the plane was the first aircraft in the U.S. inventory specifically built for towing aerial targets. All combat equipment was replaced with the cables and reels needed to tow the large targets used in aerial gunnery practice. The B-57E could be converted to a bomber and a number of them were converted to replace combat loses in Vietnam. Two aircraft were also converted to act as airborne relays for real-time video reconnaissance over Vietnam. While the system, code named, "Compass Site" was successful it was never deployed to Vietnam
