In 1975, the Air Force Considered Turning the A-10 Warthog Into a Nuclear Bomber

Security,

In December 1975, Secretary of Defense Bill Clements wanted to know how much it would cost to modify F-15 and F-16 fighter jets so they could carry atomic weapons. Two months later, the Air Force sent back data on what it would take to upgrade those two types of aircraft—or the A-10—with nukes.

Needless to say, the Air Force didn’t recommend strapping atomic weapons to the A-10s. Nor is there any record that the Air Force considered the idea ever again.

Despite what the Pentagon and senior Air Force leaders might say, the A-10 Warthog is far from a “single-purpose airplane.” But dropping nuclear bombs might be one of the things the low- and slow-flying attackers actually can’t do.

But the Air Force once briefly considered the idea.

In December 1975, Secretary of Defense Bill Clements wanted to know how much it would cost to modify F-15 and F-16 fighter jets so they could carry atomic weapons. Two months later, the Air Force sent back data on what it would take to upgrade those two types of aircraft—or the A-10—with nukes.

“For your information, we have also provided similar cost data on the A-10 aircraft,” states an unclassified memo War Is Boring obtained from the Air Force Historical Research Agency. “The estimated cost to make 275 A-10s nuclear-capable is $15.9 million.”

The total amount—equivalent to more than $65 million today—would cover developing and testing the required equipment, and installing it on the Warthog fleet.

The flying branch’s calculations included systems needed to support B-43, B-57 and B-61 bombs.

At the time, these three bombs were the standard nuclear weapons for aircraft in the U.S. military. If a shooting war broke out in Europe, America’s NATO allies would have gotten access to these weapons, too. Newer versions of the B-61 remain in service today.

Obviously, the Air Force never ended up arming the A-10s with nukes.

But Clement’s desire for more nuclear-armed aircraft is hardly surprising. During the Cold War, the Pentagon expected to use nuclear bombs, artillery shells and missiles to fend off a Soviet invasion of Europe.

“As new aircraft are coming online in the 1970s, their use as nuclear delivery aircraft would have been discussed,” Air Force historian Brian Laslie says. “Tactical delivery of nuclear weapons was surely to be in planning documents for a European theater conflict.”
