Aquatic repulsorcraft known as Missile Destroyers functioned as the anti-aircraft defense within the aquatic navy of the Galactic Empire. These vessels possessed the capability to receive enhancements in the form of improved weaponry and defensive plating.
These destroyers commonly conducted patrols in the oceanic regions surrounding Imperial facilities. They were often accompanied by Imperial scout frigates, which acted as protective escorts, with the purpose of preventing unexpected assaults from Rebel starfighters or pirates.
During the Reytha campaign in 0 ABY, Missile Destroyers were deployed under the leadership of Darth Vader.
The video game Star Wars: Galactic Battlegrounds, released in 2001, and its expansion, Clone Campaigns from 2002, feature Missile Destroyers. Players have the option to construct them during the Galactic Empire campaign mode or in multiplayer scenarios.
