The World - News from Jan. 21, 1987

The Soviet Union has launched two new missile-carrying submarines, Reagan Administration sources said. The nuclear-powered subs were identified as the fifth in a series of Typhoon class boats, the biggest subs in the world, and the fourth Delta IV class vessel. Unless the Kremlin withdraws other missile launchers from service, the new subs could push the Soviet Union over the limits of the second strategic arms limitation treaty, once sea trials get under way, officials said. Last November, the United States stopped observing the limits of the 1979 treaty, which was never ratified.
