TSAR BOMB. Nuclear explosion

Tsar Bomba (Russian: Царь-бомба) is the nickname for the AN602 hydrogen bomb, the most powerful nuclear weapon ever detonated. It was also referred to as Kuz'kina Mat (Russian: Кузькина мать, Kuzka's mother), potentially referring to Nikita Khruschev's promise to show the U.S. a Kuzka's mother (Kuzkina mat) at the 1960 UN General Assembly.
