747 CMCA - Cruise Missile Carrier Aircraft
The 747 CMCA was a proposed cruise missile carrier considered during B-1 development.
This variant was considered by the U.S. Air Force as a Cruise Missile Carrier Aircraft during the development of the B-1 Lancer strategic bomber. It would have been equipped with 50 to 100 AGM-86 ALCM cruise missiles on rotary launchers. This plan was abandoned in favor of more conventional strategic bombers.
