[edit] Milestone nuclear explosions

The following list is of milestone nuclear explosions. In addition to the atomic bombings of Hiroshima and Nagasaki, the first nuclear test of a given weapon type for a country is included, and tests which were otherwise notable (such as the largest test ever). All yields (explosive power) are given in their estimated energy equivalents in kilotons of TNT (see megaton).

Date Name Yield (kT) Country Significance
16 Jul 1945 Trinity 19 Flag of the United States USA First fission device test, first plutonium implosion detonation
6 Aug 1945 Little Boy 15 Flag of the United States USA Bombing of Hiroshima, Japan, first detonation of an enriched uranium gun-type device

29 Aug 1949 RDS-1 22 Flag of the Soviet Union USSR First fission weapon test by the USSR
3 Oct 1952 Hurricane 25 Flag of the United Kingdom UK First fission weapon test by the UK

31 Oct 1961 Tsar Bomba 50,000 Flag of the Soviet Union USSR Largest thermonuclear weapon ever tested
16 Oct 1964 596 22 Flag of the People's Republic of China PR China First fission weapon test by the People's Republic of China
17 Jun 1967 Test No. 6 3,300 Flag of the People's Republic of China PR China First "staged" thermonuclear weapon test by the People's Republic of China
24 Aug 1968 Canopus 2,600 Flag of France France First "staged" thermonuclear test by France
18 May 1974 Smiling Buddha 12 Flag of India India First fission nuclear explosive test by India
11 May 1998 Shakti I 43 Flag of India India First potential fusion/boosted weapon test by India
(exact yields disputed, between 25kt and 45kt)
11 May 1998 Shakti II 12 Flag of India India First deployable fission weapon test by India
28 May 1998 Chagai-I 9-12 Flag of Pakistan Pakistan First fission weapon test by Pakistan.
9 Oct 2006 Hwadae-ri <1 Flag of North Korea North Korea First fission device tested by North Korea; resulted as a fizzle

"Deployable" refers to whether the device tested could be hypothetically used in actual combat (in contrast with a proof-of-concept device). "Staging" refers to whether it was a "true" hydrogen bomb of the so-called Teller-Ulam configuration or simply a form of a boosted fission weapon. For a more complete list of nuclear test series, see List of nuclear tests. Some exact yield estimates, such as that of the Tsar Bomba and the tests by India and Pakistan in 1998, are somewhat contested among specialists.
