The Endurance-class fleet carrier served as the centerpiece of modern Allied fleets composed of Alliance warships.
The Endurance had a Class 1 hyperdrive and could carry 1,600 troops and enough consumables for five months. However, weapons had to be sacrificed to make room for extra fighters. Endurance-class fleet carriers were only armed with a secondary armament of twelve turbolaser cannons, twenty laser cannons, eight ion cannons, and four tractor beam projectors.
While they boasted improved hull integrity, their shields were markedly less powerful. Although they were equipped with a formidable anti-starfighter weapon system, the fleet carriers were usually protected by screening ships and starfighters. They were not designed to enter the savage heart of battle, but to deploy and coordinate smaller ships.
The main fighting punch of an Endurance-class ship consisted of almost four wings of starfighters. One wing was a short-range assault wing composed of bombers and starfighters for close support. Another wing was a long-range superiority wing composed of hyperdrive-equipped fighters.
Introduced circa 2102 N.E and sharing a space frame with the Nebula Star Destroyer, the Endurance Fleet Carrier was a key component of the Alliance of Civilization’s New Class Modernization Program. Sacrificing much of the Nebula’s heavy weaponry in exchange for additional hangar space, and featuring an enlarged bridge superstructure, the Endurance could field almost four complete starfighter wings into battle while also functioning as primary command ship for Allied forces.
