Mok Tuka's Lucrehulk-class Battleship

During the Clone Wars, a Lucrehulk-class Battleship served in the naval forces of the Confederacy of Independent Systems as the flagship of Commander Mok Tuka. During the Battle of Abrion Major, the battleship was stationed in the Abrion system, as the command ship of the blockade of the planet Abrion Major, which was attacked by the Galactic Republic fleet of Jedi General Del Morrigan. Following a brief stalemate, the Republic managed to defeat majority of the blockade. The Republic proceeded to fire at the ship's central control core, destroying the entire ship with Tuka failing to escape.

Description
The Lucrehulk-class Battleship was a 3,356.9-meter long, 3,009-meter wide, and 1,028.77-meter tall vessel that was equipped with three Rendili StarDrive manufactured Proton 2 sublight engines and four sensor rectennas. It also contained control signal transmission towers and sixteen droid signal receiver stations with signal pickup boost panels designed to squelch noise and interference. The battleship was additionally armed with its own weapon systems, as well as equipped with escape pods and communication systems capable of contacting a Munificent-class star frigate or Venator-class Star Destroyer.

Battle with Republic forces
In 20 BBY towards the end of the Clone Wars, the Confederacy of Independent Systems began the establishment of a massive droid manufacturing facility as well as a research facility on the planet Abrion Major. The droid factory contributed to the manufacturing of numerous battle droid units for the Separatist Droid Army, making the factory one of the most valuable during the final years of the war. Due to the value of the facilities, the Separatists established a blockade in orbit around the planet.

Commander Mok Tuka led the blockade from his Lucrehulk-class Battleship which was reinforced by a few various Separatist starships. The following year, the blockade was contested by a Galactic Republic fleet led by Jedi General Del Morrigan. Prior to the commencement of the battle, General Greez Findo doubted him on his ability to withstand the attack. Tuka reassured Findo of his confidence in the blockade. During the battle, there was a brief stalemate that occurred. Both sides sent squadrons of starfighters to attack, but eventually the Republic forces bested the Separatists.
