[1], The second major change to the RB-57D was the addition of Pratt & Whitney J57 engines in place of the Wright J65 engines used on all earlier B-57 models.
The pilot and navigator who flew these missions never even got to view the film they shot.

In 1959, two RB-57Ds were delivered to replace the A-types; one of them was shot down over China by a SA-2 Guideline missile, marking the very first successful operational engagement of surface-to-air missiles.
The primary mission of these aircraft was high-altitude photo reconnaissance. This page was last edited on 20 September 2020, at 23:15. The definitive B-57B, which introduced numerous improvements, made its first flight on 18 June 1954.
Even with the spoilers out and landing gear extended, the plane had a very low sink rate and pilots resorted to holding the RB-57Ds into a series of slight stalls to get the aircraft down to the runway. [1], On 16 September 1950, the USAF formally issued a request for a jet-powered bomber; the sought aircraft had to possess a top speed of 630 mph (1,020 km/h), ceiling of 40,000 feet (12,190 m), and range of 1,150 miles (1,850 km).
[4] The Canberra was used extensively during the Vietnam War in a bombing capacity; dedicated versions of the type were also produced and served as high-altitude aerial reconnaissance platforms (the Martin RB-57D Canberra), and as electronic warfare aircraft.
Although initially conducted by active duty Air Force units, the EB-57 mission eventually migrated to selected units of the Air National Guard. [6], Due to the great urgency placed on delivering the B-57A Canberra, the initial phase of manufacturing performed by Martin used a minimum-change formula to expedite production; thus the first B-57As to be produced were largely identical to the Canberra B.2. The Martin B-57 Canberra is an American-built, twinjet tactical bomber and reconnaissance aircraft that entered service with the United States Air Force (USAF) in 1953.
[3], RB-57D "5643", piloted by Capt Ying-Chin Wang, was shot down and killed on 7 October 1959 by a People's Liberation Army SA-2 surface-to-air missile, which was the first successful shoot-down of an aircraft ever achieved by a SAM.
[12], The substantial design changes between the B-57A and B-57B models resulted in delays to the overall program, as well as incurring substantial costs on the fixed-price contract. 7 – RB-57D Model 744 (53-3970 to 53-3976) – (Group B) Basic configuration with in-flight refuelling.
