Its test on 30 October 1961 remains the most powerful man - made explosion in history . It was also referred to as Kuzkina mat (Russian: Кузькина мать; "Kuzma's mother"), possibly referring to Nikita Khrushchev's promise to show the United States a Kuzkina mat (an idiom roughly translating to "We'll show you!") at a 1960 session of United Nations General Assembly . </P> <P> The bomb had a yield of 50 megaton TNT (210 PJ). In theory, it had a maximum yield of 100 megatons if it were to have included a U-238 tamper, but because only one bomb was built, this was never demonstrated . The single bomb was detonated at the Sukhoy Nos cape of Severny Island, part of Novaya Zemlya . </P>
