The Tsar Bomba, also known as the King of Bombs, was manufactured in the Soviet Union with a yield of 50 megatons, equivalent to 50 million tons of TNT. It was detonated on October 30, 1961, over Novaya Zemlya in the Arctic Circle. The bomb was transported by aircraft. A hydrogen bomb uses nuclear fusion reactions, with a destructive power many times greater than atomic bombs. The Tsar Bomba test was conducted while the United States was attempting to develop air-deliverable thermonuclear weapons and had conducted the Castle Bravo test in the Pacific Ocean in 1954. Castle Bravo was the code name for the most powerful hydrogen bomb tested by the United States, with a yield one-third that of the Tsar Bomba.

Among all three nuclear bomb tests by the Soviet Union, 173, 174, 147, they all took place in Novaya Zemlya, with the destructive power of all three events being 21 megatons, roughly 1000 times that of the explosion in Nagasaki, Japan.
These are respectively the third, fourth, and fifth most powerful nuclear explosions in human history. A bomb like this could potentially devastate everything within a 7.8km² area.

The Explosive Incident of Castle Bravo
Castle Bravo detonation occurred precisely on August 28, 1954, recognized as the most destructive bomb in the Castle series of nuclear tests. Initially estimated at 6 megatons, its actual yield reached 15 megatons, forming a towering mushroom cloud reaching 35km high. This miscalculation was a grave error by the United States, resulting in severe radiation exposure for 665 residents in the Marshall Islands.
The Castle Bravo detonationThe Novaya Zemlya 25 Explosion
Novaya Zemlya Explosion number 25 was conducted by the Soviet Union in April 1962, yielding a devastating force of 19.1 megatons. Currently, images of this explosion remain classified.
The Novaya Zemlya 25 ExplosionThe Novaya Zemlya 123 Incident
The Soviet Union conducted the test explosion known as Novaya Zemlya 123, with a yield of 12.5 megatons. Currently, there is no specific video footage of this explosion.
The Novaya Zemlya 123 IncidentOn the day of May 4th, 1954, the detonation of the Castle Yankee bomb occurred precisely, marking the second major blast for the United States within the Castle campaign, boasting a devastating yield of 13.5 megatons.
The radioactive fallout from this explosion reached as far as Mexico City, a distance of over 11,000 kilometers from the test site, in just 4 days. With such destructive power, this explosion could inflict third-degree burns within an area encompassing approximately 4,500 square kilometers.
The event known as Castle Yankee reverberated with profound impact.The Ivy Mike detonation, a pivotal moment in nuclear history, marked the inaugural test of a thermonuclear device, also known as a hydrogen bomb, with a yield approximately 700 times greater than the first atomic bomb dropped by the United States on Hiroshima.
This momentous explosion yielded an estimated 10.2 megatons, resulting in the destruction of a significant portion of Elugelab Island, leaving behind a crater 50 meters deep and a mushroom cloud towering up to 42 kilometers in height.
The event known as Ivy Mike heralded a new era in weapons development and geopolitical strategy.Behold Castle Romeo, a cornerstone of the Castle campaign in 1954, where the fiery embrace of thermonuclear power was tested with a yield of 11 megatons.
Rather than being confined to an island, Castle Romeo met its destiny atop the azure waters of the Bikini Atoll coral reef. Its detonation razed everything within a 5-kilometer radius.
The saga of Castle Romeo unfolds as a testament to the relentless pursuit of nuclear prowess amidst the vast expanse of the Pacific.Experience the detonations of Novaya Zemlya 158 and 168, where the Soviet Union unleashed nuclear tests on August 25, 1962, and September 19, 1962, respectively. Both events took place in the northern Soviet testing ground near the Arctic, in close proximity to the North Pole.
Each test yielded a destructive force estimated at nearly 10 megatons, incinerating everything within an area of approximately 4.6 square kilometers and causing third-degree burns within a region spanning 2800 square kilometers. To this day, no images or footage exist documenting these tests.
The saga of Novaya Zemlya 158 and 168 unfolds as a testament to the obscured annals of nuclear history, shrouded in secrecy and destruction.
