The BDS Rustolium served primarily as a scout and patrol boat in the coastal waters of Brookshire. It's age limits the utility of the craft, seeing it consigned mostly to coastal work such as intercepting small craft and the laying of minefields. The Rustolium was modelled after the Gotzborger Montin-class U-Boat. One peculiar quirk of the Rustolium was that it had been outfitted in such a way that its engines could be made to sound like a commercial fishing trawler, when running on the surface. Although spared the fate of much of the historic fleet of Brookshire.
