Star Destroyer
The iconic "Imperial"-class Star Destroyer first appears in the opening scene of "Star Wars" (1977), where the Imperial Star Destroyer "Devastator", with Darth Vader on board, chases the CR90 Corvette "Tantive IV" (carrying Princess Leia) above Tatooine after have fled from Scarif. Background literature describes "Imperial"-class Star Destroyers as the chief warship of the Imperial Navy and symbol of Imperial might. These enormous capital ships are used to enforce the Emperor's will, bolster Imperial-backed governments, and act as mobile headquarters for senior Imperial commanders. In addition to their powerful armament, a Star Destroyer carries troops and vehicles for ground operations and a full wing of TIE Fighters (typically 48 fighters, 12 bombers and 12 boarding craft). A single Star Destroyer is considered sufficient to overwhelm a rebellious planet, though major industrialized worlds may be assaulted by a fleet of six Star Destroyers with support cruisers and supply craft. Deep-crust survival bunkers are regarded as a last refuge in the event of planetary bombardment by Imperial Star Destroyers.
