The automated droid cruisers functioned as combat units controlled by droids, and they were deployed to protect Tig Fromm's headquarters located on Ingo. During the year 15 BBY, these droid cruisers were employed in an attempt to stop Thall Joben, Jord Dusat, Kea Moll, R2-D2, and C-3PO from fleeing the base. Nevertheless, C-3PO managed to reactivate the Fromm Tower Droids, which then turned against the droid cruisers, creating a distraction that enabled the group's successful escape.
