<P> Tsar Bomba ( Russian : Царь - бомба ; `` Tsar - bomb '' ) was the Western nickname for the Soviet RDS - 220 hydrogen bomb ( code name Ivan or Vanya ) , the most powerful nuclear weapon ever detonated . 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>
