What is the most poweful nuclear weapon of all time?

I have read reports of the peacekeeper icbm and the soviet ss-18 both holding 10 warheads each about 20 times as powerful as hiroshima. does anyone know for a fact what the world's most powerful nuclear weapon is?

    Tsar Bomba (Russian: Царь-бомба, literally "Tsar-bomb") is the Western name for the largest, most powerful nuclear weapon ever detonated or built. Developed by the Soviet Union, the bomb of about 50 megatons was codenamed Ivan by its developers.

    The bomb was tested on October 30, 1961 in Novaya Zemlya, an island in the Arctic Sea. The device was scaled down from its original design of 100 megatons to reduce the resulting nuclear fallout...

    Codenamed "Ivan" during its development, the Tsar Bomba was not intended for use in warfare, but should be seen as an instance of the Cold War-era saber-rattling indulged in by the USSR and the USA.

    The Tsar Bomba was a multi-stage hydrogen bomb with a yield of about 50 megatons (Mt). The initial three-stage (fission-fusion-fission) design was capable of approximately 100 Mt, but at a cost of too much radioactive fallout. To limit fallout, the third stage, consisting of a uranium-238 fission tamper (which greatly amplifies the reaction by fissioning uranium atoms with fast neutrons from the fusion reaction), was replaced with one made of lead. This eliminated fast fission by the fusion-stage neutrons, so that approximately 97% of the total energy resulted from the fusion stage alone (as such, it was one of the "cleanest" nuclear bombs ever created, generating a very low amount of fallout relative to its yield). There was a strong incentive for this feature regression, as most of the fallout from a test of the bomb would fall on populated Soviet territory.

    The bomb, weighing 27 tonnes, was so large (8 meters long by 2 m in diameter) that the Tu-95 had to have its bomb bay doors and wing fuel tanks removed. The bomb was attached to an 800 kg fall retardation parachute, which gave the release and observer planes time to fly about 45 km from ground zero. Failing such retardation, the bomb would have either reached its planned detonation altitude so fast it would have turned the test into a suicide mission, or crashed into the ground at high speed, with unpredictable results.

    The Tsar Bomba detonated at 11:32 a.m., located approximately at 73.85° N 54.50° E [2], over the Mityushikha Bay nuclear testing range (Sukhoy Nos Zone C), north of the Arctic Circle on Novaya Zemlya Island in the Arctic Sea. The bomb was dropped from an altitude of 10,500 m, and designed to detonate at a height of 4,000 m over the land surface (4,200 m over sea level) by barometric sensors.

    The original USA estimate of the yield was 57 Mt, but since 1991 all Russian sources have stated its yield as "only" 50 Mt. Nonetheless, Khrushchev warned in a filmed speech to the Communist parliament of the existence of a 100 Mt bomb (technically the design was capable of this yield). The fireball touched the ground, reached nearly as high as the altitude of the release plane, and was seen 1,000 km away. The heat could have caused third degree burns at a distance of 100 km. The subsequent mushroom cloud was about 60 km high and 30–40 km wide. The explosion could be seen and felt in Finland, even breaking windows there.[citation needed] Atmospheric focusing caused blast damage up to 1,000 km away. The seismic shock created by the detonation was measurable even on its third passage around the earth.

    Since 50 Mt is 2.1×1017 joules, the average power produced during the entire fission-fusion process, lasting around 3.9×10-8 seconds or 39 nanoseconds, was a power of about 5.3×1024 watts or 5.3 yottawatts. This is equivalent to approximately 1% of the power output of the Sun. The detonation of Tsar Bomba therefore qualifies, even to this day, as being the single most powerful device ever utilized throughout the history of humanity. By contrast, the largest weapon ever produced by the United States, the now-decommissioned B41, had a predicted maximum yield of 25 Mt, and the largest nuclear device ever tested by the USA (Castle Bravo) yielded 15 Mt...

    You seem to have missed one little goody: the neutron bomb. it somewhat is the little attractiveness that wipes out each little thing this is controlled via desktops international huge via scrambling up their digital circuits and turning their "brains" into mush, so as that each little thing they administration grinds to a halt. Oh particular, there is likewise the "cobalt bomb." it somewhat is the only which does not destroy something while it explodes. It only spreads a great dose of radioactivity over an extremely great section, to that end sentencing each residing factor in that section to a sluggish, agonizing dying from huge radioactive poisoning.

    The Soviets once built and detonated a huge nuclear bomb-I can't recall how many kilotons. It was too bulky to be weaponized however-they just wanted the biggest bang.

    67Impala is absolutely correct, that thing is today still known as the biggy...it simply set a bar very high as well as American stakes in the arms race. No more to be said, but the Triton is considered very formiddable today. Not sure on this, but I believe the British may have some real big nasties too these days.

    The yield of the B-83 bomb is 71 times larger than that used at

    Hiroshima and 47 times larger than Nagasaki.

    tsar bomba

    50or 51kiloton bomb radius of 110 mile include radiation

    it was more of a propaganda bomb because in real wars it was too heavy to fly with
