Victory I-class Star Destroyer

The Victory-class Star Destroyer was a destroyer designed for planetary defense, planetary assault and ground troop support, and ship-to-ship combat.

General Characteristics
Victory-class ships are 900 meters long, making them some of the largest capital ships capable of atmospheric operations. A single Victory-class Star Destroyer requires 4,798 crewmembers and 402 gunners for optimal operation, and can transport up to 2,040 troops, 8,100 metric tons of cargo, several ground vehicles like the AT-AT and 2 squadrons of starfighters. Despite being several decades old, the shields and hull plating of Victory-class ships are still quiet heavy. They are equipped with 10 quad turbolaser batteries, 40 double turbolaser batteries, 80 concussion missiles (high yield, arranged in 20 tubes of 4 missiles each), 10 tractor beam projectors and 2 defector shield generators.

History
Designed by Walex Blissex and produced by Rendili StarDrive, the Victory-class was a direct challenge to Kuat Drive Yards’ Venator-class Star Destroyer. The Galactic Republic’s military saw a need for heavier starships as fighting intensified towards the end of the Clone Wars. The majority of the initial commission group was not deployed until Palpatine had already dissolved the Galactic Republic and established his Imperial rule.

Within the Imperial Starfleet, Victory-class Star Destroyers are considered second only to Imperial-class Star Destroyers. Heavy squadrons featured a Victory class ship as their primary unit, and at the systems force level, they support Imperial-class Star Destroyers in major assaults. The abundant number of Imperial-class ships, and the growing popularity of the Imperial-class amongst the Imperial Navy, led to many being decommissioned or sold to groups like the Corporate Sector Authority, which purchased 250 of these. Most of the Victory-class Star Destroyers still seeing Imperial service are often assigned to planetary defense roles.

The Victory-class Star Destroyer's biggest disadvantage is in ship to ship combat because it's LF9 Ion Engines can't produce enough sufficient speed to pursue the newer and faster ships that outrun it. When Grand Admiral Thrawn came into power the Victory-class found itself being used more often by the Imperial Remnant because of a lack of Imperial-class Star Destroyers.

Behind the Scenes
The Victory-class Star Destroyer was created from rejected concept art for A New Hope. Roleplaying game statistics published by West End Games originally gave the Victory-class 80 concussion missile tubes, with an unknown number of missiles. This was later retconned to 80 missiles in 4 tubes by the book Starships of the Galaxy, published by Wizards of the Coast.
