The BSX-5 Dreadnaught represented a unique iteration of the Harrower-class dreadnought, seeing service within the ranks of the re-established Sith Empire throughout the duration of the Cold War.
The most well-known BSX-5 type ship was the Dominator, which functioned as the command vessel for Darth Jadus. Its destruction occurred while the Sith Lord was aboard, leading to the widespread assumption of Jadus's death in the resulting blast. During the pursuit of Vyord Yanol, a subordinate of Darth Jadus, an Imperial Agent uncovered a restricted file on Yanol's computer, which contained the schematics for the Dominator.
