abbreviationStandard termMaritime

The ship prefix for vessels of the historic Italian Royal Navy.

Regia Nave translates to Royal Ship and served as the official designation for warships operating under the Italian monarchy. The prefix appeared before the vessel's name on naval registries, dispatch logs, and hull markings. It functioned exactly like HMS for British vessels, distinguishing commissioned military units from civilian merchant craft.
