The Bell X-16 was a high altitude reconnaissance jet aircraft designed in the United States in the 1950s. A mock-up of the X-16 was built, but the project was cancelled in favor of the Martin RB-57 before any X-16 aircraft were completed. The designation of X-16 was a cover to try to hide the true nature of the aircraft mission from the Soviet Union during the Cold War.[1]
Development[]
During the second half of 1953, Fairchild, Bell, and Martin Aircraft conducted high altitude reconnaissance aircraft design studies for the United States Air Force under project MX-2147.[2] All three designs used Pratt & Whitney J57-19 engines. The Bell and Martin (B-57D) designs were chosen for further development. The Bell Model 67 design was designated the X-16. A full-scale X-16 mock-up was completed and one aircraft was partially completed. It was designed as a high altitude long-range reconnaissance aircraft. The X-16 design was breaking new ground with its design. Its wing was long (114.83 feet) with a high aspect ratio (11.9). It was significantly lighter and more flexible than usual jet aircraft wings. The entire aircraft was made as light as possible to fulfill its mission of a 3,000-mile unrefueled range at a 69,500 ft altitude.[2]
A total of 28 aircraft were ordered, but none were completed. The first X-16 was about 80 percent complete when the program was cancelled by the Air Force in favor of the Martin RB-57 in 1956. Although no X-16 was ever completed, it made contributions to aircraft design with its lightweight design. It was also a driving force behind the development of the high-altitude J57 jet engine that would later power the Lockheed U-2 and other aircraft.
