GDA Super Dreadnought

The GDA Super-Dreadnought is a terrifyingly massive warship, serving as both a flagship and the seat of power for The Controller, the leader of the Green Drone Armada. It was only used in the final days of the Green Drone War, when the Controller transported the Artifact, the symbol of the GDA's power, to the edge of a black hole and began charging the Artifact to unleash its powers on the galaxy, until the Super-Dreadnought was destroyed during the subsequent battle after which it was pulled into the black hole.

History
During the Invasion of P3-X2, the massive attack on the GDA's capital world by Red Wood Industries (RWI) and Crazy North Logistics (CNL), the Controller and the Commander, his second-in-command, retreated from their headquarters to avoid capture by RWI forces led by Captain Jack Roberts. Soon after eluding capture, a massive warship was detected emerging from the surface of P3-X2 by the RWI Apollo, which was revealed to be the Super-Dreadnought. Initial scans showed that it was twice the size of an RWI Daedalus-class Battleship and most RWI weaponry wouldn't even scratch the hull. The Super-Dreadnought, along with multiple GDA Destroyers, were engaged by the Apollo and the rest of the RWI/CNL fleet in orbit, who were soon joined by the "Ghost Fleet" of the Royal Coalition of Spatial Protection (RCSP), but the massive Super-Dreadnought and its escorts were able to break orbit and eventually escape.

The Super-Dreadnought jumped into the vicinity of a black hole, where it began charging the Artifact. Soon after, a massive fleet of RWI, CNL, and RCSP ships jumped into the system and engaged the GDA flotilla. Heavy casualties were taken on both sides until it was just the Super-Dreadnought remaining. Captain Roberts, along with his crew, infiltrated the Super-Dreadnought, fighting through security, planting charges along the inside of its hull, and eventually killing both the Commander and the Controller, as well as disrupting the Artifact's charge sequence. Though the Super-Dreadnought had managed to destroy several RWI ships during the infiltration mission, including Roberts' starship, the RWI Eclipse, before the crippling blow was dealt. The strike team was able to escape, detonating the charges and leaving the remains of the Super Dreadnought, along with the Artifact, to drift into the black hole, never to be seen again. With the Super-Dreadnought's destruction, the Green Drone War came to an end.
