| 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 US a Kuzka's mother (Kuzkina mat) at the 1960 UN General Assembly. The famous Russian idiom, which has been problematic for translators, equates roughly with the English "We'll show you!" in this usage meaning "something that has not been seen before".[1] Developed by the Soviet Union, the bomb was originally designed to have a yield of about 100 megatons of TNT (420 PJ), but the yield was reduced to 50 megatons in order to reduce nuclear fallout. This attempt was successful, as it was one of the cleanest (relative to its yield) nuclear bombs ever detonated. Only one bomb of this type was ever built and it was tested on October 30, 1961, in the Novaya Zemlya archipelago.[2][3] The remaining bomb casings are located at the Russian Atomic Weapon Museum, Sarov (Arzamas-16), and the Museum of Nuclear Weapons, All-Russian Research Institute of Technical Physics, Snezhinsk (Chelyabinsk-70). Neither of these casings has the same antenna configuration as the device that was tested. Many names are attributed to the Tsar Bomba in the literature: Project 7000; product code 202 (Izdeliye 202); article designations RDS-220 (РДС-220), RDS-202 (РДС-202), RN202 (PH202), AN602 (AH602); codename Vanya; nicknames Big Ivan ... |
