Abbreviation for "Hydrogen Bomb". The hydrogen bomb is the big brother of the first nuclear bombs, Fat Man and Little Boy, which were dropped on Nagasaki and Heroshima in 1945.

The hydrogen bomb uses a hydrogen neutron, fired at high speed, into an atom of some unstable element, usually uranium. This causes the uranium particle to separate. This, in turn, releases alot of enegry. The two halfs then proceed to re-do the above steps in a Chain Reaction, which is called fission.

Usually with a blast diameter of 10+ miles, as opposed to 1 mile diameter for an A bomb.
