The Atomic Technology of War:

Nuclear technology in war: spread of nuclear weapons During the Second World War, scientists from several countries conducted experiments related to nuclear reactors and fissile weapons, but the separation of uranium 235 or the production of -239 Except for other countries. At the beginning of the war on September 1, 1939, the Axis countries had special offices for military applications of fission; it plans to conduct uranium and carbon chain reaction experiments, and uranium peers I am studying how to separate the body.

The atomic bomb and nuclear bomb are powerful weapons that use nuclear reaction as an explosive energy source. Scientists first developed nuclear weapons technology during the Second World War. At the end of the Second World War, the United States used only two atomic bombs in two wars against Japan. During the proliferation after the war, during the Cold War, the United States and the Soviets competed for advantage in the global nuclear weapons competition. Many of the studies were conducted under the direction of the theoretical physicist J. Robert Oppenheimer of Los Alamos, New Mexico. On July 16, 1945, in the remote desert area near Alamogordo, New Mexico, the first atomic bomb exploded successfully - Trinity test. It created a huge mushroom cloud, about 40,000 feet tall, and told us the arrival of the atomic era.

August 29, 1949, the Soviet Union exploded the first atomic bomb at the semi-paratinsk test site in Kazakhstan. The case ended US monopoly on nuclear weapons and promoted the Cold War. In the 1950s, arms race competition became the focus of the Cold War. The United States tested the first hydrogen (or thermonuclear) bomb in 1952 and defeated the "super bomb" made by Russians. When the US Secretary of State John Foster Dulles announced this policy called "collective retaliation" in January 1954, the political situation of the Cold War became clearer - any major Soviet attack would be massive nuclear Due to the reaction "mass retaliation", the most important byproduct of the Cold War - intercontinental ballistic missile (ICBM) has emerged
