NYT: "New Video Shows Largest Hydrogen Bomb Ever Exploded"

Last week, the Russian nuclear energy agency, Rosatom, released a 30-minute, formerly secret documentary video about the world’s largest hydrogen bomb detonation. The explosive force of the device — nicknamed Tsar Bomba, or the Tsar’s bomb, and set off on Oct. 30, 1961 — was 50 megatons, or the equivalent of 50 million tons of conventional explosive. That made it 3,333 times as destructive as the weapon used on Hiroshima, Japan, and also far more powerful than the 15 megaton weapon set off by the United States in 1954 in its largest hydrogen bomb blast.
