The Ultima-class Super Star Destroyer was the most powerful warship ever built by the Sith Order of Decreto, and the direct descendant of the Decreto-class Super Star Destroyer. They served in much the same role as their predecessors – as command & control vessels; being the flagships of various Sith Lords. Although warship bore no physical resemblance to its forerunner save the spear tipped nose, they were basically the same. The Ultima-class however had much stronger defenses and weapons, but had a substantially slower speed.
