different letters in the alphabet

An "A-bomb" is usually a fission bomb (plutonium or Uranium fissions = splits into lighter elements)

An "H-bomb" is a fusion bomb wherein Hydrogen (or some isotope of it) "fuses" into heavier elements. Often an H-bomb needs the energy of an A-bomb to start its nuclear reaction but the output is SO much greater that the A-bombs energy output is dwarfed by the enormous fusion explosion.
