Last Nuclear 'Monster Weapon' Gets Dismantled

In the 1960s, the skies above the United States were patrolled by agents of the apocalypse. Air Force B-52 Stratofortresses circled the North American continent, 24 hours a day, cradling two megabombs in their bellies. Those B-53 bombs each weighed 10,000 pounds. Were one to drop on the White House, a nine-megaton yield would destroy all life out into suburban Maryland and Virginia.

It was the ultimate Cold War weapon, the one that Major Kong would have ridden into Armageddon at the end of Dr. Strangelove. And on Tuesday, it will no longer exist.

Out at the Energy Department’s Pantex Plant near Amarillo, Texas, the last of America’s B-53s is in storage. Come Tuesday, it will be dissected: The 300 pounds of high explosives will be separated from its enriched uranium heart, known as a “pit.” The pit will be placed into a storage locker at Pantex, where it will await a final, highly supervised termination.

“It’s the end of the era of monster weapons, if you will,” says Hans Kristensen, who directs the Nuclear Information Project at the Federation of the American Scientists.

First brought into the U.S. nuclear stockpile in 1962, the B-53 was so big because it was so dumb. With poor precision mechanisms for finding a target — “Its accuracy was horrendous,” Kristensen says — what it lacked in smarts it made up in strength. The nukes that vaporized Hiroshima were a mere 12 kilotons; the B53 provided nine megatons — 9,000 kilotons — of destructive power.

And it was designed to burrow deep. The B53 wasn’t just any old megabomb. It was the first bunker buster. U.S. nuclear doctrine called for it to be delivered over suspected underground Soviet command-and-control facilities. The dumb bomb wouldn’t destroy them so much as it would destroy everything remotely near it, leaving — literally — a smoldering crater. That was the U.S. plan for “victory” in a nuclear war right up until the implosion of the Soviet Empire.

At its height, the U.S. had 400 of the mega-gravity bombs. But it was decommissioned in 1997, so it’s not as if the U.S. suddenly finds itself without its massive gravity bomb. It’s been a slow process of destruction ever since, although Pantex spokesman Greg Cunningham says that he can’t say how long it takes to destroy one of the bombs.

The America’s nuclear arsenal remains enormous; the U.S. will still have 1,500 atomic weapons, by the time the latest U.S.-Russia nuke treaty runs its course. But with the end of the B-53 comes a belated end to a Cold War relic.

“It was one heck of a whopper,” Kristensen says. “We have nothing that comes close to it in the stockpile anymore, and neither does Russia. It’s the end of an era.”
