The US’s last ultra powerful nuclear bomb has been dismantled. A weapon a hundreds of times stronger than the bomb dropped on Hiroshima is being disassembled nearly half a century after it was put into service at the height of the Cold War. The final components of the B53 bomb will be taken apart Tuesday at the Pantex Plant near Amarillo Texas, the nation's only nuclear weapons assembly and disassembly facility. The completion of the dismantling program is a year ahead of schedule, according to the U.S. Department of Energy's National Nuclear Security Administration, and aligns with President Barack Obama's goal of reducing the number of nuclear weapons in the US.
Thomas D'Agostino, the nuclear administration's chief, called the bomb's elimination a "significant milestone."
Put into service in 1962, when Cold War tensions peaked during the Cuban Missile Crisis, the B53 weighed 10,000 pounds and was the size of a minivan. According to the American Federation of Scientists, it was 600 times more powerful than the atomic bomb dropped on Hiroshima, Japan, killing as many as 140,000 people and helping end World War II.
Since the B53 was made using older technology by engineers who have since retired or died, developing a disassembly process took time. Engineers had to develop complex tools and new procedures to ensure safety.
"We knew going in that this was going to be a challenging project, and we put together an outstanding team with all of our partners to develop a way to achieve this objective safely and efficiently," said John Woolery, the plant's general manager.
The plant will play a large role in similar projects as older weapons are retired from the U.S.'s nuclear arsenal.
