The Pantex Plant, located 17 miles northeast of Amarillo, has dismantled the last B53 atomic bomb still intact in the United States.
The bomb was fist manufactured in 1962 at the height of the Cold War with Russia, and was retired in 1997. At the time of its retirement, the B53 was the oldest, the largest, and the most destructive weapon in the U.S. nuclear arsenal. The device weighed 10,000 lbs and carried 300 lbs of high-end explosives.
Pantex is the nation's only facility for building, maintaining, and disassembling nuclear weapons.
