3 new Soviet SS-20 bases could be finished by fall

The Soviet Union is completing work on three more SS-20 missile bases, and is expected to conclude its deployment program by the fall, NATO sources said.

Two of the bases are sited west of the Ural Mountains and one in the Asian part of the country, the sources said. The missiles have a 3,000-mile range. Richard Burt, US assistant secretary of state-designate for European affairs, said last month that Soviet statements about a unilateral freeze were misleading.
