Kuat Drive Yards weapons platform

"The Emperor has commandeered other, more sophisticated space construction centers in other systems, notably the Kuat Drive Yards and the Rendili and Loronar space construction facilities, for assembling his largest battleships and special weapons platforms."

- Pollux Hax

The Kuat Drive Yards weapons platform was a class of military space station produced for the Imperial Navy at the Kuat Drive Yards. It required sophisticated shipyards for its production, beyond the capabilities of facilities like those near Coruscant which could produce Imperial I-class Star Destroyers.

Behind the scenes
This weapons platform is only mentioned in The Illustrated Star Wars Universe, as an aside during Imperial propagandist Pollux Hax's description of the shipyards of Coruscant. The broadest interpretation of the only passage which describes this platform, as well as the Loronar and Rendili battleships, is that all three facilities produced large battleships and weapons platforms.

However, the passage could also be interpreted in a more narrow fashion. Since various other sources show that Kuat Drive Yards produced large capital ships such as the Executor-class Star Dreadnought, and Loronar and Rendili produced armed space station designs (such as Loronar Corporation's Torpedo Sphere and Rendili StarDrive's Bavos-II military space platform), Pollux Hax's statement could still be correct if Kuat was responsible for the "largest battleships", while Rendili and Loronar built "special weapons platforms."
