On October 30, 1961, the Soviet Union conducted a nuclear test that was a turning point in the military atomic arms race.<\/p>\n

That day, a modified Tupolev Tu-95V bomber, serial number 5800302, took off from the Soviet Navy air base at Olenya<\/strong>, on the Kola Peninsula, with a crew of nine. The aircraft was coated with reflective white paint<\/strong>, intended to protect the airmen from the effects of the nuclear explosion.<\/p>\n

The aircraft flew toward Novaya Zemlya<\/strong>, a Russian archipelago located within the Arctic Circle. The Tu-95V carried an RDS-220 atomic bomb, also known as the Tsar Bomba, mounted on its underside<\/strong>. The name was a reference to the 200-ton Tsar Kolokol bell displayed in the Kremlin, which is the largest bell in the world.<\/p>\n

The device had a yield of 50 megatons<\/strong>, weighed 27 tons, and measured 8 meters long by 2 meters wide. To give you an idea, it was 3,800 times more powerful than the Little Boy bomb dropped by the US on Hiroshima<\/strong> on August 6, 1945. The Tsar Bomba was twice as powerful as the largest nuclear bomb ever created by the US, the B41.<\/p>\n

The bomb was dropped at 11:30 a.m. from an altitude of 10,500 meters.<\/strong> The bomb's descent was delayed by the deployment of a series of parachutes to give the Tu-95V time to move away from the blast zone. The Tsar Bomba detonated its nuclear warhead at 11:33 a.m. at an altitude of 4,200 meters above sea level.<\/strong> It was the largest explosion ever created by humankind. The mushroom cloud reached an altitude of 65 kilometers. The colossal explosion was visible from 1,000 kilometers away<\/strong>, despite the cloudy sky, and could have caused third-degree burns within a 100-kilometer radius of the detonation point.<\/p>\n

The Tsar Bomba was designed to destroy large cities, but its detonation caused a global shock<\/strong>, leading to the signing of the first agreements banning atmospheric nuclear testing by the United States. Severny Island was flattened, the ground leveled by the explosion.<\/strong> It should be noted that the USSR tested a total of 130 nuclear weapons in Novaya Zemlya, the radioactivity of which affected not only Soviet territory but also parts of Alaska, northern Canada, and Norway.<\/p>\n

Yesterday, Blue Paw Print<\/a> (a YouTube channel I recommend you subscribe to) published an excellent video explaining the design of the Tsar Bomba and how it was detonated<\/strong>, as well as its repercussions:<\/p>\n
