The YC-14 was Boeing's entrant into the USAF's Advanced Medium STOL Transport (AMST) competition, which aimed to replace the C-130 Hercules as the USAF's standard STOL tactical transport. Although both the YC-14 and the competing McDonnell Douglas YC-15 were successful, neither aircraft entered production, and the AMST project was eventually shut down in 1979.

After the commercial success of the L-049 Constellation, Lockheed produced a slightly improved version designated L-749. This aircraft attracted the attention of the U.S. Air Force, which bought ten of them for long-range VIP transports and designated them VC-121A. The new transports proved to be very popular and regularly carried high-ranking Generals and Presidents.
The U.S. Army Air Forces issued its first requirement for a jet bomber in 1943. However, it was not until after the war, when German research on high-speed aircraft became available that the design of the B-47 was finalized. The B-47 became the first all jet bomber produced anywhere in the world. Over two thousand Stratojets were built between 1947 and 1957.
The B-36 is the largest bomber and the last piston engine powered bomber produced by the United States. First designed to meet a World War II requirement for a plane capable of hitting targets in Germany from bases in the United States the prototype did not fly until August 8, 1946.
The B-52 "A" built only 3 pieces. None of the B-52As ever entered operational service with the USAF. 52-0003 was modified to NB-52A standard and used as a "mother ship" for the X-15.
