Hoersch-Kessel Drive, Inc. functioned as a company that built starships. The Confederacy of Independent Systems utilized vessels made by them throughout the Clone Wars, notably the Lucrehulk-class LH-3210 cargo freighter, the Lucrehulk-class Battleship, as well as the Munificent-class star frigate.
The initial reference to Hoersch-Kessel Drive, Inc. occurred in The Star Wars Sourcebook, a Star Wars Legends supplement from 1987 authored by Bill Slavicsek and Curtis Smith for Star Wars: The Roleplaying Game. Its integration into canon happened with its mention in Ultimate Star Wars, a reference work collaboratively written by Patricia Barr, Adam Bray, Daniel Wallace, and Ryder Windham, which saw release on April 28, 2015.
