Fifth Soviet Nuclear Test, First Hydrogen Bomb
Joe-4 was the fifth Soviet nuclear test and demonstrated the use of fusion in a weaponizable design known as the Sloika or "Layer Cake" design. The device obtained nearly all of its yield from fission and was limited for practical purposes to yields of less than 1Mt. The RDS-6s warhead used a U-235 fissile core surrounded by alternating layers of lithium-6 deuteride spiked with tritium, and a uranium fusion tamper inside a high explosive implosion syst -
RDS-37: The First Soviet Superbomb
InfoThis device, designated RDS-37, was the Soviet Union's first test of a two-stage radiation implosion design.This was also the world's first air-dropped fusion bomb test (and the 24th Soviet test overall). After this test the Soviet Union used radiation implosion exclusively. The bomb weighed 1.6 megatons. -
Raduga

Test 219
Test 219 was a nuclear test conducted by the Soviet Union in the atmosphere via ICBM. The test was performed on December 24, 1962 over at the Novaya Zemlya test range. The yield was 24.2 Mt making it the second largest thermonuclear explosion in history. -
Test Ban Treaty
InfoRepresentatives of the United States, Soviet Union and Great Britain signed the Limited Nuclear Test Ban Treaty. -
Chagan Nuclear Test
Chagan was the first and largest of the 124 detonations in the Nuclear Explosions for the National Economy program, designed to produce peaceful nuclear explosions for earth-moving purposes. The concept of using larger bombs to create artificial lakes, harbors and canals. Lake Chagan, Kazakhstan, is a lake created by the Chagan nuclear test. It -
Last Test
The last Soviet test took place on October 24, 1990. After the dissolution of the USSR in 1992, Russia inherited their former nuclear stockpile, but has not conducted any nuclear tests.
