The Mk/B53 was a high-yield bunker buster thermonuclear weapon developed by the United States during the Cold War with a yield of 9 megatons, which results in a fireball with an approximate 2.9 to 3.4 mi diameter and the radiated heat causes lethal burns to any unprotected person within a 20-mile radius. It was the most powerful weapon in the U.S. nuclear arsenal. This weapon is no longer used actively. Manufacturer of this bomb was  The United States Atomic Energy Commission, commonly known as the AEC. That was an agency of the United States government established after World War II by U.S. Congress to foster and control the peacetime development of atomic science and technology.
