In the early-1970s, the U.S. Air Force issued an Advanced Medium STOL Transport requirement for a new jet-powered tactical airlifter to replace the Lockheed C-130 Hercules. |
 |
In 1972, two proposals were accepted for construction as the Boeing YC-14 and McDonnell Douglas YC-15 prototypes. |
 |
The Boeing Model 953 design for STOL performance was based on the use of a supercritical wing which provides highly efficient performance from the wing at high subsonic speeds. To this wing Boeing added an advanced wing upper-surface blowing concept, mounting the twin turbofan engines forward and above the wing so that their efflux was exhausted over the wing (this location also gave the airplane a quieter noise footprint). |
 |
With the wing's leading-edge flaps and Coanda-type trailing-edge flaps extended, the high-speed airflow from the engines tended to cling to the upper surface of the wing/flap system and was thus directed downward to provide powered lift. It was the most efficient powered-lift system ever developed. |
 |
The YC-14's basic mission was to carry large, bulky payloads into and out of short, rough dirt fields that were less than 2,000 ft. long, even if an engine failed. It had a large fuselage to accommodate most tanks, trucks and armored personnel carriers used by the U.S. Army |
 |
At the completion of testing in the late summer of 1977, the YC-14 prototypes were returned to Boeing for continuing development if the company so wished. Due to budget restrictions, no further government funding for development or procurement was made. |
