The Tsar Bomba was a three-stage bomb with a Trutnev-Babaev [28] second- and third-stage design, [29] with a yield of 50 Mt. [4] This is equivalent to about 1,570 times the combined energy of the bombs that destroyed Hiroshima and Nagasaki, [30] 10 times the combined energy of all the conventional explosives used in World War II, [31] one ...
1939 – September 1 – World War II begins after the invasion and subsequent partition of Poland between Nazi Germany and the Soviet Union. 1939 – October – U.S. President Franklin D. Roosevelt receives the Einstein–Szilárd letter and authorizes the creation of the Advisory Committee on Uranium.
RDS-37, November 22, 1955: first Soviet multi-megaton, true hydrogen bomb test using Andrei Sakharov's third idea, essentially a re-invention of the Teller-Ulam. Tsar Bomba, October 30, 1961: largest nuclear weapon ever detonated, with a design yield of 100 Mt, de-rated to 50 Mt for the test drop.
The Tsar Bomba (Царь-бомба) was the largest, most powerful thermonuclear weapon ever detonated. It was a three-stage hydrogen bomb with a yield of about 50 megatons. [58] This is equivalent to ten times the amount of all the explosives used in World War II combined. [59]
A similar chart focusing solely on quantity of warheads in the multi-megaton range is also available. [17] Moreover, total deployed US & "Russian" strategic weapons increased steadily from the 1980s until the Cold War ended. [18] The United States nuclear stockpile increased rapidly from 1945, peaked in 1966, and declined after that. [1]
Developed between 1956 and 1961 as the Soviet Union engaged in a nuclear arms race with the United States, the Tsar Bomba - the King of Bombs - was the largest hydrogen bomb ever and was claimed ...
France had been heavily involved in nuclear research before World War II through the work of the Joliot-Curies. This was discontinued after the war because of the instability of the Fourth Republic and lack of finances. [75] However, in the 1950s, France launched a civil nuclear research program, which produced plutonium as a byproduct.
This crash project was developed partially with information obtained via the atomic spies at the United States' Manhattan Project during and after World War II. The Soviet Union was the second nation to have developed and tested a nuclear weapon. It tested its first megaton-range hydrogen bomb ("RDS-37") in 1955.
