Hades (; or , Háides) was the ancient Greek chthonic god of the underworld, which eventually took his name.

The Hadès system was a short-range ballistic pre-strategic nuclear weapon system designed by France, as a last warning before use of strategic nuclear weapons, in the perspective of a Soviet invasion of Western Europe. It was designed from July 1984 as a replacement for the tactical road-mobile Pluton missile. Initially 120 missiles were planned to be deployed.
