Following an announcement last year by Russian President Vladimir Putin in his annual State of the Union address, Russia is now about to deploy at least 30 high-tech, underwater nuclear drones that, according to the Russian news agency Tass, would each be “capable of carrying a nuclear warhead with a yield of up to two megatons to destroy enemy naval bases.” A two-megaton nuclear device delivers more than 133 times the explosive force of the atomic bomb dropped on Hiroshima, Japan, by a United States aircraft on August 6, 1945.
The most powerful nuclear weapon currently in the United States arsenal, the B83 thermonuclear bomb, delivers 1.2 megatons of explosive force, according to The Brookings Institute. One megaton is the equivalent of 1 million tons of the explosive material TNT.
