1969-1976: US Anti-Ballistic Missile Program Scaled Back, Eventually Terminated

After Richard Nixon wins the presidency (see November 5, 1968), he orders a review of the Sentinel anti-ballistic missile program (see September 18, 1967). It is suspended and later reintroduced in a more modest form under the moniker “Safeguard.” Nixon says the program will protect “our land-based retaliatory forces against a direct attack by the Soviet Union.” Safeguard has serious conception and design flaws, and is never completely deployed; when the 1972 Anti-Ballistic Missile Treaty is signed with the Soviet Union (see May 26, 1972), the program is scaled back and eventually terminated by Congress. Author Stephen Schwartz will later write that the Sentinel/Safeguard program is “the only time that Congress has successfully voted down a major strategic nuclear weapons program supported by the executive branch.” [Schwartz, 1998, pp. 286-288; Federation of American Scientists, 1/15/2008]
