The U.S. wants to make a new nuclear bomb which will be 24 times more powerful than the one that levelled Hiroshima at the end of World War II.

It has a maximum yield of 360 kilotons. “The announcement is reflective of growing threats from potential adversaries,” Assistant Secretary of Defense for Space Policy John Plumb said in the release.
