Soviet Atomic Bomb Project

Soviet Atomic Bomb Project

The Soviet project to develop an atomic bomb (Russian: Создание советской атомной бомбы) was a clandestine research and development program begun during and post-World War II, in the wake of the Soviet Union's discovery of the United States' nuclear project. This scientific research was directed by Soviet nuclear physicist Igor Kurchatov, while the military logistics and intelligence efforts were undertaken and managed by NKVD director Lavrentiy Beria. The Soviet Union benefited from highly successful espionage efforts on the part of the Soviet military intelligence (GRU). During the midst of World War II, the program was started by Joseph Stalin who received a letter from physicist Georgy Flyorov urging him to start the research, as Flyorov had long suspected that many of the Allied powers were already secretly advancing after the discovery of nuclear fission in 1939. However, because of the bloody and intensified war with Germany on the Eastern Front, the large scale efforts prevented Soviets from developing the atomic bomb, but accelerated the program after the American atomic bombings of Hiroshima and Nagasaki, thus putting an end to World War II. The Soviet atomic project was charged with gathering intelligence efforts on German nuclear program as well as the American nuclear efforts. After the atomic raids on Japan and the subsequent Japanese surrender in 1945, the Soviet Union expanded its research facilities, military reactors, and employed a number of scientists, including its atomic spies who successfully penetrated the American nuclear weapons efforts.

Greatly aided by its successful Russian Alsos and the atomic spy ring, the Soviet Union's research and espionage ultimately led them to conduct the first test of its implosion-type nuclear device, codename First Lightning on 29 August 1949, at Semipalatinsk, Kazakh SSR. With the success of this test, the Soviet Union became the second nation after the United States to have successfully developed and conducted nuclear tests.
