Soviet Atmospheric Tests

Last updated 7 October 1997

This is a complete list of all Soviet nuclear tests conducted during the era of atmospheric testing. Not included are "hydronuclear tests", what are tests involving fissile material with yields (by design) of less than 1 ton. Explosive device fizzles with yields of less than 1 ton are included however.

Abbreviations

When the exact yield of a test is known, the enti=ries in the minimum and maximum yield columns are identical.
