Impervium Plating

Impervium plating.

Impervium was a tremendously resilient alloy frequently used for the armor on capital ships. It was stronger than duranium, another type of protective metal.[1]

Behind the scenesEdit

Impervium was first mentioned in the Star Wars Legends article Soldiers of the Empire! in 1978.[2] Its first known canonical appearance was in the mobile-game Star Wars: Galactic Defense after a 2015 update.[1]
