A thermonuclear weapon, fusion weapon or hydrogen bomb (H bomb) is a second-generation nuclear weapon design. Its greater sophistication affords it vastly greater destructive power than first-generation nuclear bombs , a more compact size, a lower mass, or a combination of these benefits.
It was claimed at the time to be the first British test of a H-bomb. It was later revealed to be a fusion boosted fission nuclear weapon test, where the fusion boosting failed to increase the yield. It still yielding 720 kT of explosive power, probably the largest A-bomb test ever.
The Tsar Bomba far surpassed the largest explosion the United States has ever conducted - a 15-megaton "Castle Bravo" hydrogen bomb detonated on Bikini Atoll in 1954. (Reporting by Maria Vasilyeva ...
Orange Herald fireball and subsequent mushroom cloud, film reel captured from a trailing aircraft. Orange Herald was a British nuclear weapon, tested on 31 May 1957.At the time it was reported as an H-bomb, although in fact it was a large boosted fission weapon and remains to date, the largest fission device ever detonated.
But it was still below the 2 megatonnes of TNT (8.4 PJ) safety limit. This was the real hydrogen bomb Britain wanted, but it used a relatively large quantity of expensive highly enriched uranium. Due to the higher-than-expected yield of the explosion, there was some damage to buildings, the fuel storage tanks, and helicopters on the island. [150]
Bomb disposal personnel from the Japanese Ground Self Defense Force determined that the explosion was caused by an American 500-pound bomb that was likely dropped during a World War II air raid.

In the video game Sid Meier's Civilization VI, Operation Ivy is a late game project that the player can construct at one of their cities. Completing the project allows the player to construct thermonuclear devices, which are more powerful than nuclear devices (which are the game's version of an atomic bomb).
