Family: Miscellany. Country: USA. Status: Study 1961. Other Designations: Space Launch System BC-2720.

In 1961 the Air Force completed several years of studies for a family of advanced heavy-lift launch vehicles for use in the late 1960's and on. Development of solid and liquid rocket engines was already begun to support this effort. One member of this family, selected to boost the Air Force Lunex lunar lander on a direct lunar trajectory, was the BC-2720. This would have used four 180 inch solid rocket boosters strapped around an the 'C' Lox/LH2 core vehicle. The core would have required either 12 J-2 engines or 2 M-1 engines. The translunar injection third stage was the 'B', with a single J-2 engine.

NASA, not the Air Force, received the task of going to the moon and building large boosters. But the Saturn series was abandoned, while the BC-2720 resembles very much the Shuttle configuration. Perhaps if things had been different...
