During the Imperial period, the Mediterranean became a peaceful "Roman lake"; in the absence of a maritime enemy, the navy was reduced mostly to patrol and transport duties.

On the fringes of the Empire however, in new conquests or, increasingly, in defense against barbarian invasions, the Roman fleets were still engaged in warfare. The decline of the Empire in the 3rd century took a heavy toll on the navy, which was reduced to a shadow of its former self, both in size and in combat ability. As successive waves of the Völkerwanderung crashed on the land frontiers of the battered Empire, the navy could only play a secondary role. In the early 5th century, the Roman frontiers were breached, and barbarian kingdoms appeared on the shores of the western Mediterranean. One of them, the Vandal Kingdom

Although Rome had relied on her legions for the conquest of Italy, operations in Sicily had to be supported by a fleet, and the ships available by Rome's allies were clearly insufficient. Thus in 261 BC, the Roman Senate set out to construct a fleet of 100 quinquereme

The new fleets were commanded by the annually elected Roman magistrates, but naval expertise was provided by the lower officers, who continued to be provided by the socii, mostly Greeks. This practice was continued until well into the Empire, something also attested by the direct adoption of numerous Greek naval terms.

Crews

The bulk of a galley's crew was formed by the rowers, the remiges (sing. remex) or eretai (sing. eretēs) in Greek. Despite popular perceptions, the Roman fleet, and ancient fleets in general, relied throughout their existence on rowers of free status, and not on galley slave

ian rank. In the Punic Wars for instance, one consul would usually command the fleet, and another the army. In the subsequent wars in the Eastern Mediterranean, praetors would assume the command of the fleet. However, since these men were political appointees, the actual handling of the fleets and of separate squadrons was entrusted to their more experienced legates and subordinates. It was therefore during the Punic Wars that the separate position of praefectus classis ("fleet prefect") first appeared.

Initially subordinate to the magistrate in command, after the fleet's reorganization by Augustus, the praefectus classis became a procurator

, the status of the praefectura was raised, and only equestrians with military experience who had gone through the militia equestri were appointed. Nevertheless, the prefects remained largely political appointees, and despite their military experience, usually in command of army auxiliary units, their knowledge of naval matters was minimal, forcing them to rely on their professional subordinates. The difference in importance of the fleets they commanded was also reflected by the rank and the corresponding pay of the commanders. The prefects of the two praetorian fleets were ranked procuratores ducenarii, meaning they earned 200,000 sesterces annually, the prefects of the Classis Germanica, the Classis Britannica and later the Classis Pontica were centenarii (i.e. earning 100,000 sesterces), while the other fleet prefects were sexagenarii (i.e. they received 60,000 sesterces).

Ship types

The generic Roman term for an oar-driven galley warship was "long ship" (Latin: navis longa, Greek: naus makra), as opposed to the sail-driven navis oneraria, a merchant vessel, or the minor craft (navigia minora) like the scapha.

The navy consisted of a wide variety of different classes of warships, from heavy polyremes to light raiding and scouting vessels. Unlike the rich Hellenistic Successor kingdoms

 to draw upon, fielded a fleet also mostly composed of quinquiremes, but with a sizeable complement of heavier warships, ranging from "sixes" to "tens" (Gk. dekērēs). Later historical tradition made much of the prevalence of lighter and swifter vessels in Octavian's fleet, with Vegetius

 even explicitly ascribing Octavian's victory to the liburnians.

This prominence of lighter craft in the historical narrative is perhaps best explained in light of subsequent developments. After Actium, the operational landscape had changed: for the remainder of the Principate, no opponent existed to challenge Roman naval hegemony, and no massed naval confrontation was likely. The tasks at hand for the Roman navy were now the policing of the Mediterranean waterways and the border rivers, suppression of piracy, and escort duties for the grain shipments to Rome and for imperial army expeditions. Lighter ships were far better suited to these tasks, and after the reorganization of the fleet following Actium, the largest ship kept in service was a hexareme, the flagship of the Classis Misenensis

. The bulk of the fleets was composed of the lighter triremes and liburnians (Latin: liburna, Greek: libyrnis), with the latter apparently providing the majority of the provincial fleets. In time, the term "liburnian" came to mean "warship" in a generic sense.

In addition, there were smaller oared vessels, such as the navis actuaria, with 30 oars (15 on each bank), a ship primarily used for transport in coastal and fluvial operations, for which its shallow draught and flat keel were ideal. In late Antiquity, it was succeeded in this role by the navis lusoria

Armament and tactics

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 ballista

s. 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
Boarding (attack)
Boarding, in its simplest sense, refers to the insertion on to a ship's deck of individuals. However, when it is classified as an attack, in most contexts, it refers to the forcible insertion of personnel that are not members of the crew by another party without the consent of the captain or crew...

. 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

, 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.

After the end of the civil wars, Augustus reduced and reorganized the Roman armed forces, including the navy. A large part of the fleet of Mark Antony was burned, and the rest was withdrawn to a new base at Forum Iulii (modern Fréjus

, supplemented by a growing number of minor ones in the provinces, which were often created on an ad hoc basis for specific campaigns. This organizational structure was maintained almost unchanged until the 4th century.
Praetorian fleets

The two major fleets were stationed in Italy and acted as a central naval reserve, directly available to the Emperor (hence the designation "praetorian"). In the absence of any naval threat, their duties mostly involved patrolling and transport duties. These were not confined to the waters around Italy, but throughout the Mediterranean. There is epigraphic evidence for the presence of sailors of the two praetorian fleets at Piraeus and Syria. These two fleets were:
