In 1966, the U.S. Air Force began studies for a successor to the LGM-30 Minuteman ICBM. In April 1966, the new ICBM program was officially started as Weapons System 120A AICBM (Advanced Intercontinental Ballistic Missile), and in July that year the designation ZBGM-75A was allocated to the missile. The BGM-75 was to be a solid-rocket powered missile, to be used with both hardended (silo) and mobile (train) basing schemes. However, the AICBM program was not approved by the Secretary of Defense and cancelled in 1967. It was not until 1972 that the Air Force began another ICBM program, the then planned to be mobile MX (later LGM-118 Peacekeeper). Specifications

The BGM-75 program was cancelled before any design work was done.
