A line of capital ships manufactured by Kuat Drive Yards.
Imperial-Class Star Destroyers are the arm of the Galactic Empire's military might and the peak of Imperial engineering, each one coming in a different class ranging from star dreadnoughts, battlecruisers, cruisers, and Victory-Class Star Destroyers, each with unique functions.
The standard is the Imperial Class Type I, which is 1,600 meters long and has a width of 900 meters and is able to go 60 mGLT per hour comfortably and 975 km/h in the atmosphere. Each star destroyer was outfitted with shielding and 60 Taim & Bak XX-9 heavy turbolaser batteries, 60 Borstel NK-7 ion cannons, 6 dual heavy turbolaser turrets, 2 dual heavy ion cannon turrets, 40 point-defense laser cannons, Heavy Phylon Q7, and 10 tractor beam projectors, along with a complement of 72 tie fighters of varying sizes and makes. The main weapons outfitted on this specific star destroyer are able to glass cities with one bridge of cannon fire, but it would take multiple death stars numbering in the dozens in order to glass an entire planet, while the secondary weapons are only capable of destroying asteroids and are meant for short range and clearing room to go into hyperspace.
While this Object of Power uses Imperial Class Type I as a base, you can opt to acquire any Star Destroyer variant.
