- Historical event:
- 12 August 1953
- The Soviet bomb tested on this day was as many as 25 times more powerful than the American bomb dropped on Hiroshima in 1945. The Soviets made a total of 456 nuclear explosions at the Semipalatinsk Test Site.
On this day in 1953 the USSR detonated its first thermonuclear bomb.
Of course, thermonuclear weapons produce much more powerful (up to 1,000 times) explosions than standard nuclear (fission) bombs. The Soviet bomb detonated on this day had an explosive force of 400 kilotons, 25 times more than the American bomb dropped on Hiroshima in 1945.
The bomb was tested at the Semipalatinsk Test Site. The site is located on the territory of what is now eastern Kazakhstan, towards China and Mongolia. It is interesting that the Soviets conducted a total of 456 nuclear tests on this site.
