 Despite the creation of the Tu-95V bomb-carrier aircraft, the actual test of the Tsar Bomba was postponed for political reasons; namely Khrushchev's visit to the United States and a pause in the Cold War.The Tu-95V during this period was flown to Uzin (situated in today's Ukraine) and was used as a training aircraft, therefore it was no longer listed as a combat aircraft.With the beginning of a new round of the Cold War in 1961 the test was resumed.
