The Supremacy, disparagingly nicknamed «Snoke’s Boudoir,» was a Mega-class Star Dreadnought that served as the flagship of Supreme Leader Snoke and the mobile headquarters of the First Order. It was split in two by the Resistance flagship Raddus while attempting to destroy the remnants of the Resistance fleet near the planet Crait.

The Supremacy was the sole Mega-class Star Dreadnought in the First Order‘s service with a colossal wingspan of 60 kilometers and a length of 13 kilometers. These proportions made the Supremacy the largest capital ship in galactic history. Its construction was undertaken on an unprecedented scale. As the First Order’s headquarters, the starship acted both as a command center and a battleship. Its size was gargantuan, easily outclassing all known ship sizes in galactic history, including the Star Dreadnoughts of the Galactic Empire, the trophy battlecruisers used by wealthy citizens of the waning days of the Old Republic, and even the various reconstructed versions of the flagship used by Xim the Despot.

The ship was first unveiled via the BB-9E App-Enabled Droid toy by Sphero by going through various areas and collecting data. The initial data erroneously claimed that the length of the Supremacy was over 60 km,^[2] although the confusion was rectified by Pablo Hidalgo on his Twitter feed where he clarified that the measurement was actually referring to the ship’s width via its wingspan.
