Date The nuclear arms race that originated in the race for atomic weapons during World War II reached a culminating point on October 30, , with the detonation of the Tsar Bomba, the largest and most powerful nuclear weapon ever constructed.
The Soviet Union had made halting progress in its own nuclear weapons program during the war, and in Soviet Premier Joseph Stalin ordered an intensification of these efforts. Soviet penetration of the British and American atomic weapons programs thanks to the activities of spies such as Klaus Fuchs aided the efforts of Soviet scientists to design and construct their own weapons. The Soviets successfully tested their first atomic weapon on August 29, , after which both superpowers upped the ante by working furiously to develop the far more powerful thermonuclear weapons, or hydrogen bombs.
From there the United States and the Soviet Union carried out a further series of open-air tests of atomic weapons. Great Britain emulated these with open air atomic weapons tests in the late s France would follow with tests in Polynesia in the s and beyond. While the Americans focused on perfecting accurate delivery systems for small to medium size atomic devices, however, the Soviets concentrated on building larger and larger devices of almost unimaginable power.
The Tsar Bomba was the outcome. Sakharov also played a significant role in designing this weapon, which incorporated multiple inter-reacting stages and was 26 feet long, almost seven feet in diameter, and weighed almost 60, pounds. A Tupolev Tu strategic bomber was designated to deliver the device from 34, feet. The bomb would be attached to a parachute to slow its descent to detonation at 13, feet, giving the bomber and its escort additional time to escape at least thirty miles away before detonation.
Even so, the crewmen were told that they only had a 50 percent chance of survival they barely made it. The detonation was astronomically powerful—over 1, times more powerful, in fact, than the combined two bombs dropped on Hiroshima and Nagasaki.
The mushroom cloud was 25 miles wide at its base and almost 60 miles wide at its top. At 40 miles high, it penetrated the stratosphere. A mushroom cloud forms over Nagasaki, Japan after the dropping of the second atomic bomb.
