Background (Wookieepedia)
The Xyston-class Star Destroyer, also known as the Sith Star Destroyer, was a model of Star Destroyer used by Darth Sidious' Final Order. The Sith fleet consisted entirely of these warships and engaged the Resistance in a battle within the atmosphere of Exegol. They were based on the design of the older Imperial I-class Star Destroyers, with key differences including a larger size, red accents along the hull of the vessel, and a large axial superlaser capable of destroying planets, which took the place of a standard Imperial-class Star Destroyer's main hangar space.

NOTES: 1 - Depleting the MDC of the main body will put the Carrier out of commission. All internal systems will shut down, including life support and internal gravity. The ship itself will be an unsalvageable floating wreck.
1B - Destroying the Command Tower will effectively render the ship inoperative and set the ships effectively adrift in space though the main hull will still have auxiliary power, life support and minimal maneuvering on docking thrusters.
2 - Destroying the sensor will deprive the ship of all forms of long range communications, radar and targeting. The range and targeting capabilities of the secondary systems are equal to that of a starfighter at best. The ship can still operate, but is at -3 on initiative, -3 to strike, and number of attacks per melee of the weapon systems are reduced by half.
3 - Destroying the hangers will greatly impair the carrier's ability to deploy and recover aircraft. Under normal operations the carrier can launch or recover up to starfighters or shuttles per turn. If the main hanger is destroyed this number drops to , and each hanger deck destroyed reduces this number by . If all hangers are destroyed the carrier cannot deploy any craft until at least one hanger is repaired.
4 - Depleting the MDC of the main engines will force the ship to rely on its secondary engines. Depleting the MDC of the main engines AND secondary engines will leave the ship adrift in space. If in an atmosphere, the ship will crash.
5 - Shields regenerate at 250 mdc per melee. Only if a generator is damaged will the ability for shields to regenerate be hampered in any way.
