Maj. Andrei Durnovtsev, a Soviet air force pilot and commander of a Tu-95 Bear bomber, holds a dubious honor in the history of the Cold War.

Durnovtsev flew the aircraft that dropped the most powerful nuclear bomb ever. It had an explosive force of 50 megatons, or more than 3,000 times more powerful than the Hiroshima weapon.

Over the years, historians identified many names for the test bomb.

Andrei Sakharov, one of the physicists who helped design it, simply called it “the Big Bomb.” Soviet Premier Nikita Khrushchev called it “Kuzka’s mother,” a reference to an old Russian saying that means you are about to teach someone a harsh, unforgettable lesson.

The Central Intelligence Agency blandly dubbed the test “Joe 111.” But a more popular name born out of Russian pride and a sheer awe sums it all up —the Tsar Bomba, or “the King of Bombs.”

“As far as I can tell the term did not surface until after the end of the Cold War,” Alex Wellerstein, a historian at the Stevens Institute of Technology and blogger, told War Is Boring. “Before that it was just called the 50 megaton or 100 megaton bomb.”

“I think we make a lot more of the Tsar Bomba today than anytime other than the immediate period in which it was tested.”

“Americans like to point to it as an example of how crazy the Cold War was, and how crazy the Russians are and were,” Wellerstein added. “Russians seem to take pride in it.”

On Oct. 30, 1961, Durnovtsev and his crew took off from an airfield on the Kola Peninsula and headed to the Soviet nuclear test area above the Arctic Circle at Mityushikha Bay, located in the Novaya Zemlya archipelago.

The test project’s scientists painted the Bear bomber and its Tu-16 Badger chase plane white to limit heat damage from the bomb’s thermal pulse. That’s at least what the scientists hoped the paint would do.

The bomb also had a parachute to slow its drop, giving both planes time to fly about 30 miles from ground zero before the nuke detonated. This gave Durnovtsev and his comrades a chance to escape.

When the planes reached their destination at the predetermined altitude of 34,000 feet, he ordered the bomb dropped. The chute opened, and the bomb started its three-minute descent to its detonation altitude two-and-a-half miles above the earth.

Durnovtsev pushed the throttles to the max.

Then the bomb exploded.
