Kuat Drive Yards is the largest military shipbuilding corporation in the Star Wars universe and owns several subsidiary corporations including Kuat Systems Engineering and Rothana Heavy Engineering (the latter of which provided armament and ships for Supreme Chancellor Palpatine's clone army during Clone Wars). KDY is one of the few major corporations which sided with the Galactic government during the Clone Wars, against the Confederacy of Independent Systems. Kuat Drive Yards' major competitors for major military contracts during the Imperial reign included Sienar Fleet Systems and Corellian Engineering Corporation.

After the Galactic Civil War, New Republic took control of Kuat Drive Yards and the company began production of spaceships for the Republic, however, some factories of Kuat Drive Yards continued building Star Destroyers and Walkers for the Imperial Remnant.

Kuat Drive Yards' rough parallel in the real world is Northrop Grumman Newport News, which is the only shipbuilding company in the United States which has the expertise and dockyards necessary to build the U.S. Navy's mighty nuclear aircraft carriers. The main shipyards at the Kuat system actually ring the entirety of the system and in terms of sheer manufacturing ability it was first among equals.

KDY also sells planetary turbolasers, which, according to their catalog, is the "first, last, and only line of defense" for a planet.
