B53 nuclear bomb
Closing a Cold War chapter, technicians Tuesday dismantled the last of the most powerful U.S. Nuclear bombs ever built.
An inert non-nuclear B53 training weapon is displayed during an event commemorating the dismantling of the final B53 nuclear bomb Tuesday at the Pantex Plant in Amarillo, Texas. The B53 nuclear bomb was made to deliver a 9-megaton blast about 600 times more powerful than the one that destroyed Hiroshima in 1945. Ref. Source 2
