The Role Of Intelligence Agencies In The Soviet Union's First Atomic Bomb Developed

This paper mainly studies the significance of Soviet Intelligence Service in making Soviet Union's first atomic bomb. After the Great Patriotic War, the Soviet Union's nuclear fission research have no news. The Soviet Union government get the new development of foreign atomic bomb research by Soviet Intelligence Service, so they restart the plan of nuclear at the end of 1942. Later, many scientists headed by Kurchatov spare no effort to support the latest information of Britain and U.S.A by using Soviet Intelligence Service. In August 1945, America's atomic bomb is bombing in Japan, Soviet Union speed their steps to study, finally they succeed in bombing the first atomic bomb in 1949. The essay will try to discuss this problem by using the novel decoded files of Soviet Union history.The total paper includes five parts. The beginning discuss the reasons, the significance and summaries of the research status at home and abroad for choosing the topic.The first part talk about the development state of some countries in making atomic bomb and the focus on the nuclear fission of earlier Intelligence Body.The second part outlines the state of the atomic bomb developed by States before ofthe Great Patriotic War and Soviet Intelligence Service had known the nuclear fission.The third part is a core part of the paper, which mainly tells Soviet Intelligence Service promoted developing the atomic bomb during the war. It is divided into three parts.The first part describes the research of the Soviet nuclear stalled after the outbreak of the Great Patriotic War. The second part describes the role of intelligence agencies to restart atom bomb in the Soviet Union. Information obtained by Intelligence Service haven't received much attention for many factors. But with the increase of information, the Soviet leaders has gradually payed attention to the matter. In March 1942 Beria summarized the early information, and presented it to Stalin. When the war situation changed, the Soviet Union launched a series of policies to develop their own atomic bomb. The third part describes scientists start to research their own atomic bomb by using intelligence information to the Soviet Union after restarting the nuclear research. According to the Kurchatov summary and evaluation,we can see the vital guidance role in Soviet Union nuclear research: Information which covered choice of the method of uranium isotope separation, nuclear fuel,the style of bomb structure had a great impact on the development of the first atomic bomb in the SovietThe forth part describes Intelligence Service and the Soviet Union's atomic bomb development after World War II. Though Soviet Intelligence Service gradually losed many favorable conditions to conduct intelligence activities after the war, but it has laid a good foundation on the post-war development. After United States'success, Soviet Union tried her best to bulid an atomic bomb. Finally, a successful test was done in August 1949. United States, Britain and other countries were shocked. American, Britain and Canada began to stepp up the investigation in order to find the spies who stole the atomic bomb secret.The last part is the conclusion of the paper. It remarks on the role of the intelligence agencies in the Soviet Union's first atomic bomb development.
