Imperial Navy
this was the space-going branch of the Imperial armed forces. It was formed from the naval divisions of the Grand Army of the Republic, in the wake of the Clone Wars. While the stormtroopers became the visible aspect of the Imperial military, it was the Imperial Navy that helped secure the early safety of the Galactic Empire. The huge shapes of Star Destroyers and the simple shapes of TIE Fighters became the identities of the Imperial Navy.
