Atomic testing resumedIn 1961, the Soviet Union ended a moratorium on atomic bomb testing with an above-ground nuclear explosion in central Asia. The USSR had ended speculation the day before in a TASS broadcast that announced it had resumed atomic testing, and by 5 Sep, had conducted three nuclear weapons tests. President Kennedy ordered the resumption of U.S. underground weapons testing. The U.S. response began on 15 Sep 1961 with a series of nine low yield underground experiments at Yucca Flat with a further 62 tests there in 1962. The Soviet Union activity extended to a series of 50 detonations. On 5 Aug 1963 the Limited Test Ban Treaty was signed in Moscow prohibiting testing in outer space, underwater or in the atmosphere. |
