The ABM Treaty limited the United States and the U.S.S.R. to two anti-ballistic-missile sites apiece, with no more than 100 interceptors at each one. A 1974 accord, signed at Vladivistok by Brezhnev and Gerald Ford, reduced this to one site each. The Soviets never built more than 68 interceptors, all around Moscow, and abandoned them after the '74 accord. The United States deployed a handful of missiles at one site and dismantled them.
