Testing and deployment Nuclear weapons have only twice been used in warfare, both times by the United States against Japan at the end of World War II.On August 6, 1945, the United States Army Air Forces (USAAF) detonated a uranium gun-type fission bomb nicknamed "Little Boy" over the Japanese city of Hiroshima; three days later, on August 9, the USAAF detonated a plutonium implosion-type ...

In the mid-1950s, the United States had an unconditional superiority over the USSR in nuclear weapons, although thermonuclear charges had already been created in the USSR at this time. Also, there were no effective means of delivering nuclear warheads to the US, both in the 1950s and in 1961. The USSR was therefore not able to muster a possible rea...
The bomb was officially known as "product 602" (изделие 602) or "AN602", and codenamed "Ivan". The usage of different names can be a source of confusion. The Tsar Bomba, being a modification of the RN202, is sometimes mistakenly labelled as RDS-37, RDS-202 or PH202 (product 202). It has also been referred to as RDS-220 in a number of relatively rec...
The development of a super-powerful bomb began in 1956 and was carried out in two stages. At the first stage, from 1956 to 1958, it was "product 202", which was developed in the recently created NII-1011. The modern name of NII-1011 is the "Russian Federal Nuclear Center or the All-Russian Scientific Research Institute of Technical Physics" (RFNC-V...
The initial three-stage design of Tsar Bomba was capable of yielding approximately 100 Mt through fast fission (3,000 times the power of the Hiroshima and Nagasaki bombs); however, it was thought that this would have resulted in too much nuclear fallout, and the aircraft delivering the bomb would not have had enough time to escape the explosion. To...
The explosion of Tsar Bomba, according to the classification of nuclear explosions, was an ultra-high-power low-air nuclear explosion. 1. The flare was visible at a distance of more than 1,000 km (620 mi).It was observed in Norway, Greenland and Alaska. 2. The explosion's mushroom cloud rose to a height of 67 km (42 mi).The shape of the "hat" was t...
Immediately after the test, several United States politicians condemned the Soviet Union. Prime Minister of Sweden Tage Erlander saw the blast as the Soviets' answer to a personal appeal to halt nuclear testing that he had sent the Soviet leader in the week prior to the blast. The British Foreign Office, Prime Minister of Norway Einar Gerhardsen, P...
The creation and testing of a superbomb were of great political importance; the Soviet Union demonstrated its potential in creating a nuclear arsenal of great power (at that time, the most powerful thermonuclear charge tested by the United States, Castle Bravo, had been 15 Mt). After the Tsar Bomba test, the United States did not increase the power...
The Tsar Bomba is the single most physically powerful device ever deployed on Earth, the most powerful nuclear bomb tested and the largest human-made explosion in history. For comparison, the largest weapon ever produced by the US, the now-decommissioned B41, had a predicted maximum yield of 25 Mt (100 PJ). The largest nuclear device ever tested by...
Tsar Bomba was never a practical weapon; it was a single product, the design of which allowed reaching a power of 100 Mt TE. The test of a 50-Mt bomb was, among other things, a test of the performance of the product design for 100 Mt. Experts began to develop military missilesfor warheads (150 Mt and more) that have been redirected for space use: 1...
Footage from a Soviet documentary about the bomb is featured in Trinity and Beyond: The Atomic Bomb Movie (Visual Concept Entertainment, 1995), where it is referred to as the Russian monster bomb...."World's Biggest Bomb", a 2011 episode of the PBS documentary series Secrets of the Dead produced by Blink Films & WNET, chronicles the events leading to the detonations of Castle Bravoand the Tsar...In connection with the celebration of 75 years of nuclear industry, Rosatom released a declassified Russian language documentary video of the Tsar Bomba test on YouTubein August 2020.The Manhattan Project was a research and development program undertaken during World War II to produce the first nuclear weapons. It was led by the United States in collaboration with the United Kingdom and Canada. From 1942 to 1946, the project was directed by Major General Leslie Groves of the U.S. Army Corps of Engineers.
