context_page_description: The Roman navy comprised the naval forces of the ancient Roman state. The navy was instrumental in the Roman conquest of the Mediterranean Basin, but it never enjoyed the prestige of the Roman legions. Throughout their history, the Romans remained a primarily land-based people and relied partially on their more nautically inclined subjects, such as the Greeks and the Egyptians, to build their ships. Because of that, the navy was never completely embraced by the Roman state, and deemed somewhat "un-Roman".
  In antiquity, navies and trading fleets did not have the logistical autonomy that modern ships and fleets possess, and unlike modern naval forces, the Roman navy even at its height never existed as an autonomous service but operated as an adjunct to the Roman army.
  During the course of the First Punic War, the Roman navy was massively expanded and played a vital role in the Roman victory and the Roman Republic's eventual ascension to hegemony in the Mediterranean Sea.
context_section_description: In classical antiquity, a ship's main weapon was the ram (rostra, hence the name navis rostrata for a warship), which was used to sink or immobilize an enemy ship by holing its hull. Its use, however, required a skilled and experienced crew and a fast and agile ship like a trireme or quinquereme. In the Hellenistic period, the larger navies came instead to rely on greater vessels. This had several advantages: the heavier and sturdier construction lessened the effects of ramming, and the greater space and stability of the vessels allowed the transport not only of more marines, but also the placement of deck-mounted ballistae and catapults.
  Although the ram continued to be a standard feature of all warships and ramming the standard mode of attack, these developments transformed the role of a warship: from the old "manned missile", designed to sink enemy ships, they became mobile artillery platforms, which engaged in missile exchange and boarding actions. The Romans in particular, being initially inexperienced at sea combat, relied upon boarding actions through the use of the Corvus. Although it brought them some decisive victories, it was discontinued because it tended to unbalance the quinqueremes in high seas; two Roman fleets are recorded to have been lost during storms in the First Punic War.
  During the Civil Wars, a number of technical innovations, which are attributed to Agrippa, took place: the harpax, a catapult-fired grappling hook, which was used to clamp onto an enemy ship, reel it in and board it, in a much more efficient way than with the old corvus, and the use of collapsible fighting towers placed one apiece bow and stern, which were used to provide the boarders with supporting fire.
