How many times stronger are nuclear weapons now than the ones used in WW2?
Fat man (the one detonated over Nagasaki and the more powerful of the two bombs) was 21 KILO tons – equivolant to 21 thousand tons of TNT exploding. A conventional modern bunker buster is about 1 ton, meaning fat man was the equivolant of 21 thousand of them. The Tsar bomb – the most powerful nuclear weapon ever produced, had an explosion of 50 MILLION tons of TNT (50 megatons) – but which had the potential to possibly be 100 megatons. This weapon was therefore more than 2300 times as powerful at 50mtons and about 5000 times if it really did explode at 100 mtons.
Hiroshima’s “Little Boy” gravity bomb: 12–15 kt; the first of the two nuclear weapons that have been used in warfare Nagasaki’s “Fat Man” gravity bomb: 20–22 kt; the second of the two nuclear weapons used in warfare B83 nuclear bomb: variable, up to 1.2 Mt; most powerful U.S. weapon in active service. B53 nuclear bomb: 9Mt, most powerful US warhead; no longer in active service Tsar Bomba device: 50 Mt: USSR, most powerful explosive device ever Fireball Diameters (full blast effects would extend many times beyond the fireball itself): “Little Boy”: <0.2km "Fat Man": 0.2km Tsar Bomba: 4.
