Imperatrix-class Star Destroyer

Designed to combat anything a standard ISD couldn't handle, the Imperatrix-class Star Destroyer was a beast ship. The ship's development started shortly before the destruction of the First Death Star, and was designed to use as many parts from the Imperial-class Star Destroyers. As such the ship resembles a bundle of Star Destroyers smashed together.

Around ABY 2, a trio of prototypes were being tested when the Allegiance-class Star Destroyer became more popular and swiftly replaced the Imperatrix-class. Never the less three prototypes were used by an Imperial Remnant Cell for some years after the Battle of Endor.
