Nebula-class Star Destroyer

The Nebula-class Star Destroyer, also known as the Defender-class Star Destroyer, was the largest, most powerful warship design in the New Republic's New Class Modernization Program.

Characteristics
Although it was only 1,040 meters long (65% of the length of an Imperial-class Star Destroyer), the Nebula-class was built to be a match for an Imperial II.[1] Even with a structure that was a significant departure from the Imperial-class, especially the lack of a command tower, the Nebula was often mistaken for an Imperial design due to its angular lines.[3] Its small size often lead to it being referred to as a "pocket Star Destroyer"[1], much as the later Turbulent-class would be as well.[6]

It was designed to be able to defeat any one enemy Star Destroyer, two heavy cruisers, or an entire line of smaller Imperial support ships.[1] It mounted defenses strong enough to resist even some of the smaller Super Star Destroyers or analog warships.

The armament of the Nebula-class Star Destroyer consisted of 40 heavy dual turbolaser cannons, 40 turbolaser cannons, 20 ion cannons, 8 tractor beam projectors, and 8 assault concussion missile tubes, each equipped with 30 missiles.[1] Despite the touting of far superior firepower over the Republic-class, the two had nearly similar armaments: the difference was eight concussion missile launchers for the Nebula, and two additional tractor beams for the Republic. The power generation and model of guns was different enough to make the Nebula a far superior design to the Republic. In addition, the hull armor and shield systems of the Nebula outclassed most other ships in the galaxy, including the Republic. [1]

The ships could carry up to sixty starfighters, normally including one assault wing made up of a mixture of K-wing bombers for precision strikes and Defender starfighter for close support. Nebulas could also host a space superiority wing consisting of hyperdrive-equipped E-wings, A-wings, or upgraded X-wings.[1] They also carried 1,600 troops and enough consumables for five to six months, depending on configuration.[1]

Nebula-class Star Destroyers were equipped with a Class 1 hyperdrive for faster then light travel.[1] The design also incorporated a system of lateral thrust vents to increase the ship's maneuverability, giving it far greater agility then most large capital ships.[3]

Following the New Class practice of using the same hull for multiple configurations, the Nebula-class Star Destroyers shared their basic spaceframe design with the Endurance-class fleet carriers.
