III-a1a primary hypermatter-annihilation reactor

The III-a1a primary hypermatter-annihilation reactor was a model of reactor produced by Sienar-Jaemus Fleet Systems. Resurgent-class Star Destroyers were powered by a single, large SJFS III-a1a, housed within a dome-shaped reactor containment vessel on the ship's underbelly. The massive reactor was supported by a reinforced reactor superstructure and hull chassis.
