both governments spent massive amounts to increase the quality and quantity of their nuclear arsenals. both nations quickly began the development of a hydrogen bomb and the united states detonated the first hydrogen bomb on november 1, 1952, on enewetak, an atoll in the pacific ocean. code-named "ivy mike", the project was led by edward teller, a hungarian-american nuclear physicist. it created a cloud 100 miles wide and 25 miles high, killing all life on the surrounding islands. again, the soviets surprised the world by exploding a deployable thermonuclear device in august 1953 although it was not a true multi-stage hydrogen bomb. however, it was small enough to be dropped from an airplane, making it ready for use. the development of these two soviet bombs was greatly aided by the russian spies harry gold and klaus fuchs.

bullet::::- the people's republic of china detonated its third nuclear weapon, and claimed that the bomb contained "thermonuclear material", suggesting that they had developed their own hydrogen bomb. however, meteorologists in japan said that there was no abnormal atmospheric pressure detected after the blast and that "we don't believe that the latest chinese device was a hydrogen bomb of a megaton class". china had exploded its first atomic bomb on october 16, 1964. two days later, however, japanese scientists noted that the radioactive fallout from the test was more than 30 times as great as that from either of the two earlier tests, and american officials concluded that the bomb, estimated to be 120 kilotons, was six times larger than previous weapons. the thermonuclear material in the bomb, which had been dropped from xian h-6 bomber over the test site, would be determined later to be the isotope lithium-6; china would successfully explode its first hydrogen bomb on june 17, 1967.
