Navy/Legends

A Navy was a military unit composed of various vessels and was commonly known as a Starfleet or a Defense Fleet. Though several worlds and civilizations used the word "Navy" as traditionally associated with a fleet of sea vessels, the majority of the the Galaxy primarily used it to define a fleet of starships.

Space Navies
. Numerous worlds built space navies for their own defense as well as for use by Galactic governments in times of peril. Prominent civilizations that were known for their contributions to the advancement of starfleets were the Mon Calamari and Bothans.

A Naval taskforce would normally include:
 * Flag Ship - This ship was the formal head of a naval taskforce, and usually the seat of power for the admiral in command of the fleet.
 * Capital Ships - These were normally some of the largest star ships and were often used as warships.
 * Support Ships - These vessels were commonly used to support and protect key areas of the navy.
 * Transports - These were used primarily as cargo or personnel carriers.
 * Starfighters - Fighters were small one- or two-man (sometimes three as in the case of the ARC-170) vessels used for the protection of the fleet.

Maritime Navies
The first type of ships were used to transport people or objects between lands. During wars, attack ships, called destroyers, were invented in order to attack the transports and weaken the enemy's army. The existence of the destroyer required the countermeasure of the frigates that would protect transport convoys. The next implementation were cruisers that attacked ground units, followed by anti-aircraft vessels that protected the navy from aerial attacks. The Gungans and the Selkath were among the most notable species to utilize a seaborne navy.
