HMSS Vulcan was a main shipyard and space station for the Royal Manticoran Navy, located in orbit above the planet Sphinx in the Manticore System.
The station was a RMN shipyard and refit facility, comparable to HMSS Hephaestus in the orbit of Manticore. (HH2)
In 1903 PD, the heavy cruiser HMS Fearless was heavily refitted at the shipyards after an anti-piracy patrol in the Silesian Confederacy. (HH2)
In February 1922 PD, Vulcan was completely destroyed by the Mesan Alignment Navy as part of Operation Oyster Bay. Debris from the station rained down onto the surface of Sphinx, destroying the city of Yawata Crossing, damaging many other habitats, and wiping out the Black Rock Clan of treecats. (HH12)
