The Rampa Skywatch functioned as a space-based military division within the Corporate Sector Authority. Their mission was to stop smugglers traveling through the Rampa Rapids. The planet Rampa III's arid environment meant smugglers utilized this route to bring supplies from the neighboring world of R'alla. The CSA maintained tight control over this route using their gunships.
Some years prior to the outbreak of the Galactic Civil War, Han Solo, accompanied by Chewbacca, engaged in the transportation of R'alla mineral water to the inhabitants of Rampa III.
