Almost twice the length of the Old Empire's Imperial-class Star Destroyers, the Resurgent-class Star Destroyer (also known as Resurgent-class Battlecruiser) was 2,915.81 meters in length and emulated the dagger-shaped design of its former Imperial-class vessels. Eight Resurgent-class vessels could dock with a single Mega-class Star Dreadnought.

Designed for advanced ship-to-ship combat capabilities, it served as a symbol of the First Order's power, inspiring awe in the Order's enemies and pride within its ranks.  Improving on the design of Imperial Era vessels, the ship featured hull structural bracing in its midsection. Much of the bow was split in two along the side, housing open space, supported by a truss structure.
