Task Force 7, a mostly Naval group assigned to all US pacific nuclear testing.
The US program began in 1950 and tested its first device in 1952 and tested a deliverable bomb in 1954. The USSR program began in 1950 and tested a deliverable but limited bomb in 1953 and tested a full scale deliverable bomb in 1955.
Ivy Mike shot in 1952.
1952
The first staged hydrogen bomb was developed by a team at Los Alamos, NM in 1952. It was not a practical bomb as it used cryogenic liquid deuterium-tritium and required a refrigeration system larger than itself to keep it cold.The first practical "hydrogen" bomb was developed by a team at Arzamas-16 in the USSR in 1953. It used dry lithium deuteride, however did not use staging like the 1952 US bomb did so its yield was limited. It was likely done mostly for propaganda purposes. In modern terminology it would be considered a dry boosted fission bomb, not a fusion (hydrogen) bomb.The first practical staged hydrogen bomb was developed by a team at Los Alamos, NM in 1954. It used dry lithium deuteride.The second practical staged hydrogen bomb was developed by a team at Arzamas-16 in the USSR in 1955. It used dry lithium deuteride.In the US the key central concepts of the hydrogen bomb were developed by Stanislaw Ulam and Edward Teller, in the USSR the same concepts were developed by Andre Sakharov.
Phenylcyclohexylpiperidine (PCP) was first synthesized in 1926, then patented in 1952 by Parke-Davis and marketed under the name Sernyl, a surgical anesthetic.PCP's formula is C17H25N (17 parts Carbon, 25 parts Hydrogen and 1 part Nitrogen).PCP is made synthetically from several chemicals, most of them derived from petroleum products. As the medicinal use of PCP has ceased in most places, the product on the street is made in clandestine labs.
The first hydrogen bomb "Ivy Mike" was tested in 1952.
hbomb (hydrogen bomb)
1952 Ivy Mike. Tested on Eugelab island of Eniwetok Atoll. Erased the island.
The US program began in 1950 and tested its first device in 1952 and tested a deliverable bomb in 1954. The USSR program began in 1950 and tested a deliverable but limited bomb in 1953 and tested a full scale deliverable bomb in 1955.
The 50 Megaton "Tsar Bomba" hydrogen bomb tested by the USSR in 1961 is the strongest hydrogen bomb ever detonated. The 10 Megaton "Ivy Mike" hydrogen bomb tested by the U.S. in 1952 is the physically largest hydrogen bomb ever detonated.
The first Hydrogen bomb in 1952.
1952
The bomb based on the design by Edward Teller and Stanilaw Ulam was first proposed in 1951, and tested in 1952. The first practical H-bomb (thermonuclear explosive) was built in 1954.
Ivy Mike shot in 1952.
Some 43 nuclear tests were detonated at Enewetak from 1948 to 1958. The first hydrogen bomb test, code-named Mike, was tested on November 1, 1952. The explosion vaporized the island of Elugelab. This was done for testing.
The first atomic bomb was made in 1945, the first hydrogen bomb was made in 1952.
The first successful hydrogen bomb was detonated (not launched or dropped--it was a 62-ton fixed structure) on November 1, 1952.
