unireme

A unireme was an ancient galley characterized by a single bank of oars. These vessels were among the earliest warships, evolving from converted transport boats. They were typically undecked or partially decked and featured a high, curving stem and stern. Some uniremes were equipped with a ram at the bow, a standard feature in later warships.12

The unireme was eventually succeeded by the bireme, which had two banks of oars, and then the trireme. The trireme, with its three vertically superimposed banks of oars, became the dominant warship, particularly after the Greek victory at the Battle of Salamis in 480 BCE. Triremes were light, fast, and maneuverable, with a bronze-clad ram as their primary weapon, and were crucial in naval battles throughout the 5th century BCE.13
