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.

A wheeled trailer and launcher, each carrying two missiles in containers, was planned for deploying the Hadès. The original design had a range of 250 km, which was later increased to 480 km. The guidance system was an inertial platform which could be programmed to execute evasive maneuvers before hitting the target. A version designed to hit hardened underground targets also had a final guidance system which used a GPS-based digital system, resulting in a Circular Error Probable of only 5 m, compared to a CEP of 100 m for the standard version.
