Imperator Mk III-class Star Destroyer

The Imperator Mk III subclass Star Destroyer was the result of serveral upgrades over years to the Imperator Mk II. It has improved armour and shields, and it features many more point defence weapons to make a Starbomber assault a nightmare, with much improved fast-tracking and sustained rapid-fire capacity lasers. It also has bow- and side-mounted double proton torpedo octet launchers and a cloaking device fitted as standard. It carries more support craft and typically third generation Imperial fighters such as Scimitar Starbombers and TIE Avengers.
Ref: Although never officially named, several subclasses of the Mk I and II existed. This ship reflects the upgraded ISDs under Thrawn's reign and subsequently under the Imperial Remnant.
