The Lwhekk-class Manufacturing Ship, a creation of the Ssi-ruuk, functioned as a mobile factory. It produced a variety of war materials for the Ssi-ruuvi, including Swarm-class battle droids, laser weaponry, ion weaponry, various types of droids, hand-to-hand combat weapons, and other essential supplies.
Measuring 624 meters in length, the Lwhekk-class manufacturing ship typically operated well behind the front lines of combat. Raw materials, such as asteroids and space debris, were transported via cargo shunt systems to the refinement bays, where they underwent processing to become finished products.
A typical crew consisted of 300 Ssi-Ruuk and 1,000 P'w'eck slaves, although a reduced crew of half that size was also possible. In addition, these ships accommodated 7,500 P'w'eck slave laborers and possessed storage capacity for 2,000 battle droids. Offensively, they were equipped with 3 turbolaser batteries and 20 tractor beam projectors.
