Thatcher warns UN not to trust Soviets pledge and Nott says U.K. will stress A-sub force

Declaring the Soviet Union its main threat, Britain said it will reduce its surface naval fleet, which proved vital in the Falklands war, and build a Trident nuclear submarine force for the 1990s.

Defense Secretary John Nott said the four warships lost in the South Atlantic war with Argentina will be replaced, but he did not relent on plans to reduce from 59 to 50 the total number of British destroyers and frigates.
