The Early Successors of Alexander gave a boost in the use and the development of the polyeres-type warships (multimeremes), using them widely in their wars (321 BC – early 3rd century BC). The Successors have built fleets comprised of numerous large warships, reaching the building of colossal vessels such as the ‘eikoseres’ (20reme, with twenty oarsmen on each vertical group of oars) and the enormous ‘tessarakonteres’ (40reme, with forty oarsmen on each vertical group of oars). These warships resembled to floating fortresses, very similar in size to the modern large battleships and aircraft carriers. The tessarakonteres had a crew of 6.000 men (officers, oarsmen, sailors, marines and others), as many as a modern aircraft carrier.
