Imperial Roman Warships 27 BC–193 AD (New Vanguard, 230)

The Roman Empire was not only built by the strength of the legions but also by a Navy that was the most powerful maritime force ever to have existed. It was only the existence of the fleet that secured the trade routes and maintained the communications within the huge Empire. At the height of its power the Roman Navy employed tens of thousands of sailors, marines and craftsmen, coming from every corner of the three continents under the rule of the Caesars.
