The '''Hadès''' system was a [[short-range ballistic missile|short-range ballistic]] [[tactical nuclear weapon|pre-strategic nuclear weapon]] system designed by France as a last warning before the use of strategic nuclear weapons in a prospective Soviet invasion of Western Europe. It was designed from July 1984 as a replacement for the tactical road-mobile [[Pluton (missile)|Pluton]] missile.<ref name=":0">{{Cite book |last1=Laird |first1=Robbin F. |url=https://books.google.com/books?id=AAaiDwAAQBAJ |title=The Future Of Deterrence: Nato Nuclear Forces After Inf |last2=Jacobs |first2=Betsy |date=2019-07-11 |publisher=Routledge |isbn=978-1-000-30163-2 |pages=80 |language=en}}</ref><ref>{{Cite book |last1=Rummel |first1=Reinhard |url=https://books.google.com/books?id=EK2bDwAAQBAJ |title=The Evolution Of An International Actor: Western Europe's New Assertiveness |last2=Erdmann-Keefer |first2=Vera |date=2019-06-04 |publisher=Routledge |isbn=978-1-000-30120-5 |pages=129, 136 |language=en}}</ref> Initially 120 missiles were planned to be deployed.<ref name="bb1">{{cite news |last1=Barrillot |first1=Bruno |title=Audit atomique - Le coût de l’arsenal nucléaire français (1945-2010) |url=https://www.obsarm.info/spip.php?article28 |publisher=Éditions Observatoire des armements/CDRPC}}</ref>

A [[Transporter erector launcher|wheeled trailer and launcher]], each carrying two missiles in containers, was planned for deploying the Hadès. The original design had a range of 350&nbsp;km, which was later increased to 450&nbsp;km. The guidance system was an [[Inertial navigation system|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 [[Global Positioning System|GPS-based]] digital system, resulting in a [[Circular error probable|Circular Error Probable]] of only 5 m, compared to a CEP of 100 m for the standard version.
