The Republic-class Star Destroyer is Walex Blissex's follow-up design to his Victory-class Star Destroyer. For this reason is it sometimes referred to as the Victory-class Star Destroyer Mark III. It is manufactured by Rendili StarDrive for the New Republic. The Republic-class is smaller than Lira Blissex's Imperial-class Star Destroyer, but considered to be a much more efficient design.
Although the Republic is only half the cost of an Imperial and requires a mere one-fifth the crew, it boasts 20 percent more firepower than an Imperial I model. However, it is still outmatched by the Imperial Mark II and the various Super Star Destroyers.
The vessel's armament consists of 40 heavy turbolaser batteries, 40 heavy turbolaser cannons, 20 ion cannons, and 10 tractor beam projectors. The Republic-class is only 1,250 meters long, significantly smaller than the 1,600-meter-long Imperial-class. Because the smaller ship retains a similar level of weaponry, it has to sacrifice cargo space and endurance. The Republic only holds enough consumables to operate without resupply for 2 years, one-third the running time of the Imperial.
In addition, only a single regiment of 3,200 ground troops can be carried aboard, as well as a single standard New Republic wing of 36 fighters (half the size of an Imperial wing).
