5 Confederacy of Independent Systems Star Destroyers. A mixture of Mark I and Mark II vessels appear in The Empire Strikes Back and Return of the Jedi. The Mark I was the only ISD type featured in A New Hope. More permanent variations include differences in weaponry (discussed below), and three small baffles arranged 60° apart around the main exhaust nozzles at the stern of the ISD-I. At other times the Mark I array appears in repose, as in the Battles of Hoth and Endor. There are two subtypes of Imperial-class Star Destroyers, the Mark I and Mark II designs-a distinction that seems to reflect the two distinct VFX models used in the Star Wars films visually, the main difference between these is the tractor-beam array on the very top of the superstructure - on a Mark I ship, the tractor beam array sometimes stands up to look like a tall, X-shaped structure, while the Mark II has the same array on its side to look flat. Although some Mon Calamari Cruisers are considered equivalent to the Imperial Star Destroyers in space combat, the latter has no documented equal in its multiple roles for support and planetary assault. In service with the New Republic (forged by the heroes of the Rebel Alliance after the end of the movie saga) the crews were reduced to about 28,000 men. These vessels also carry a full complement of 9,700 stormtroopers ("Imperial Marines") which brings the overall total to 46,700 men. This would include officers, technicians and computer operators, fighter pilots, and support-craft crew.
Imperial-class Star Destroyers have a complement of at least 37,000 officers and crew. When the term "Star Destroyer" is used without further qualification, it usually refers to ships of this class.Īll Imperial-class variants are said to be 1,600 meters long (approximately one mile), with three large, and four small engines capable of accelerating the ship with a force of several thousand g and a hyperdrive capable of carrying them across the galaxy in a matter of weeks. Within wider Star Wars lore, including the expanded universe, these "Imperial-class Star Destroyers" are likewise regarded as the most common class of Star Destroyer, and one of the most important symbols of the Galactic Empire, serving the Imperial fleet for at least five decades. Their official designation is Imperial-class (see section below) as of a short time after the declaration of the newly formed Empire, but during the earliest weeks of Imperial regime and the latter days of the Clone Wars, it was known as the Imperator-class.
These ships are commonly referred to as Imperial-class Star Destroyers. The term "Star Destroyer" most often refers to the common dagger-hulled combat vessels used by the Empire in the three films of the original Star Wars trilogy.
