Type UC III minelaying submarines were used by the Imperial German Navy (Kaiserliche Marine) during World War I. They displaced 474 tonnes (467 long tons) at the surface and 571 t (562 long tons) submerged, carried guns, 7 torpedoes and up to 14 mines. The ships were double-hulled with improved range and sea-keeping compared to the UC II type. The type had better seagoing, maneuvering and turning capabilities than its predecessor, while underwater stability was reduced.[1]
