During the strategic modernization program that the Soviet Union undertook in the 1970s, it deployed a large number of multiple-warhead ballistic missiles. This deployment raised concerns in the United States about vulnerability of its land-based missile force and was one of the factors that contributed to the military buildup that the United States undertook in the late 1970s-early 1980s. The newly available documents that contain evidence of the Soviet missile programs demonstrate that the "window of vulnerability" did not exist and provide some insight into the Soviet modernization program.
