HC Deb 31 July 1981 vol 9 c541W
Mr. Shore

asked the Secretary of State for Defence when the first SS20 was deployed in Western Russia; what is the present total; and how many were deployed in 1979 and in 1980.

Mr. Blaker

The first SS20 missile, with three independently targetable warheads, was deployed in Western Russia in 1977; the Soviet Union currently has about 250 SS20 missiles deployed, of which approximately two-thirds are facing Western Europe; the mid-year totals of SS20 missile deployments in 1979 and 1980 were, respectively, 120 and 160, of which again approximately two-thirds were facing Western Europe.
