The Advanced Intercontinental Ballistic Missile, also known as Weapons System 120A (WS-120A) and ZBGM-75, was a program to develop an intercontinental ballistic missile (ICBM), proposed by the United States Air Force in the 1960s as a replacement for the LGM-30 Minuteman as the Air Force's standard ICBM. Funding was not allocated for the program and the project was cancelled in 1967.
