RDS-37: The Soviet Hydrogen Bomb
The mushroom cloud from the Soviet's first hydrogen bomb
Yield: 1.6 megatons
Date: 11/ 22/ 1955
Location: Semipalatinsk
Type: Airdrop
This device, designated RDS-37, was the Soviet Union's first test of a two-stage radiation implosion ( Sakharov's "Third Idea", and Teller-Ulam) design. The bomb exploded underneath an inversion layer, which focused the shock back toward the ground unexpectedly, which caused a building to collapse and kill three people.
