As a hedge, the development of liquid deuterium weapons continued in parallel. Even though they were much less practical because of the logistical problems dealing with the transport, handling, and storage of a cryogenic device, the Cold War arms race drove the demand for a viable fusion weapon.

Many fusion or thermonuclear weapons generate much, or even most, of their yields from fission. Although the U-238 isotope of uranium will not sustain a chain reaction, it still fissions when irradiated by the intense fast neutron flux of a fusion explosion. Because U-238 is plentiful and has no
