The utility sub, an aquatic vehicle produced by Urukabb, found its purpose on Mon Calamari.
Crafted to perform diverse functions, utility subs came equipped with a range of instruments and mechanisms. These tools facilitated both minor underwater construction work and the upkeep of the numerous floating metropolises of Mon Calamari. Furthermore, they played a role in scientific investigations and archeological endeavors.
While primarily observed on the Mon Calamari home planet, Urukaab extended the reach of utility subs through exports to other aquatic planets populated by different species. These exported models featured control systems tailored to suit the requirements of their respective users.
