Soviet intelligence had information about the work on the creation of the atomic bomb in the United States comes from nuclear physicist who sympathize with the Soviet Union, in particular Klaus Fuchs. These data were presented Beria to Stalin. However, the crucial believed to have addressed to him in early 1943, a letter of the Soviet physicist Flerov, who was able to explain the essence of the problem is popular. As a result, February 11, 1943 adopted a resolution on the GKO beginning work on the atomic bomb. General management was entrusted to the deputy chairman of the GKO Molotov, who, in turn, appointed the head of the atomic project Ivan Kurchatov (his appointment was signed on March 10).

November 6, 1947 the Soviet Foreign Minister Vyacheslav Molotov made a statement regarding the secret of the atomic bomb , saying that " this secret for a long time no longer exists. " This statement meant that the Soviet Union has discovered the secret of atomic weapons , and he has at his disposal a weapon. The scientific community of the United States made this statement Molotov as a bluff , considering that the Russian can not acquire nuclear weapons before 1952. US spy satellites have discovered the exact location of Russian tactical nuclear weapons in the Kaliningrad region , which is contrary to the assertions of Moscow, which denies transfer to tactical nuclear weapons.
