Doonium/Legends

Doonium is a metal heavily used in starship hull construction. It gives ships such as those in the Imperial Starfleet their characteristic white-grey color.

Between the Battle of Yavin and the Battle of Hoth, the Empire experienced a raw materials shortage that included a shortage of doonium. As a result, many ships languished in spacedock without proper hull plating. To clear space in the Kuat drydocks, a flotilla of Victory-class Star Destroyers was equipped with red havod alloy hulls instead of the traditional doonium.
