2021年10月29日 · Los Alamos researchers were doing calculations on theoretical fission-ignited fusion bombs with yields of 100 megatons by October 1944. But making the first hydrogen bombs took a bit more time than...

In the early hours of October 30, 1961, a bomber took off from an airstrip in northern Russia and began its flight through cloudy skies over the frigid Arctic island of Novaya Zemlya. Slung below the plane’s belly was a nuclear bomb the size of a small school bus—the largest and most powerful bomb ever created.

2024年11月21日 · The frantic race to build increasingly lethal bombs after the Cold War led the US, 70 years ago, to launch the Sundial project — the most powerful weapon ever conceived. On paper, Sundial has a power equivalent to 10 billion tons of TNT, a destructive power never seen before tells the.

2025年1月27日 · Initially, the Sundial bomb was planned to be capable of producing an unprecedented 10-gigaton yield. The theoretical design of the Sundial bomb required a multi-stage process, which was known as staged thermonuclear fusion. This process involved using a fission bomb, or primary stage, to compress and ignite a secondary stage containing fusion ...

2024年12月11日 · On October 30, 1961, the Soviet Union detonated the largest nuclear weapon ever created, the “Tsar Bomba,” over Mityushikha Bay in the Arctic Circle. With an estimated yield of 50 megatons...

2024年11月6日 · Known as Project Sundial, this doomsday device would have left a 400-km radius in flames and plunged the world into darkness. It was a bomb that would destroy everything – not a weapon, but an apocalypse. How close did we come to pressing the button?

2024年12月12日 · The largest nuclear weapon ever tested was Tsar Bomba, a 50-megaton device detonated by the Soviet Union in 1961. That made it “3,300 times as powerful” as the bomb dropped on Hiroshima — an almost unimaginable level of potential destructive

2024年11月13日 · The US's top-secret project 'Sundial' is still largely classified at the time of writing, and its goal was to create a nuclear bomb with the power to destroy human civilization in one shot.
