Nebula-class Star Destroyer - Built by the Republic Engineering Corporation for the New Republic. The Nebula Star Destroyer (also known as the Defender-class Star Destroyer) was the largest and most powerful warship in the New Republic’s New Class Modernization Program. Despite being 1,040 meters long (65% of the length of an Imperial-class star destroyer), Nebulas were tough. Nebula Star Destroyers were armed with 40 heavy turbolaser batteries, 40 turbolaser cannons, 20 ion cannons, 8 tractor beam projectors, and 8 assault concussion missile tubes (each equipped with 30 missiles). These “pocket star destroyers” (nicknamed that for their small size) saw massive use in the Yuuzhan Vong War, and fought well against the extra-galactic warships. By the time of Darth Krayt’s Galactic Empire, at least one Nebula Star Destroyer (now called the Defender-class Star Destroyer) was still in service at the time.
Endurance-class Fleet Carrier - Built by the Republic Engineering Corporation for the New Republic. Like the Nebula, the Endurance-class Fleet Carrier was built as part of the New Republic Modernization Program. And Speaking of Nebula, the Endurance was built with the basic hull and systems of the Nebula. The Endurance Carriers served as parts of modern New Republic fleets. The Endurance can carry squadrons of K-Wings, E-Wings, A-Wings, X-Wings, and Defender Starfighters. However, weapons had to be sacrificed to make room for that many fighters. Endurance Carriers only had secondary armament of 12 turbolaser cannons, 20 laser cannons, 8 ion cannons, and 4 tractor beam projectors. With a high fighter capacity and low amount of heavy weapons, the Endurance Carriers had some sort of resemblance to the Venator-class Star Destroyers (that were used by the Galactic Republic during the Clone Wars).
