The destruction the B-83 would unleash would be on a scale never seen before - with the 1.2 megatonne payload making it some 75 times more powerful than the nuke detonated over Hiroshima.
Donald Trump warned that the US could deploy its most powerful nuclear weapon, the B-83 (a 1.2 megatonne bomb), "tomorrow," capable of obliterating enemy capital cities. Detonation would cause widespread destruction, millions of fatalities, severe radiation, and long-term injuries. A strike on Moscow could kill 1.3 million, destroying landmarks like the Kremlin. Similar death tolls are projected for Pyongyang (1.3 million) and Beijing (1.5 million), while Tehran could see 2.6 million fatalities. The B-83, in service since 1983, has faced repeated attempts at decommissioning.
