The v-180 Planet Defender represented a formidable planetary ion cannon of considerable size and power.
Constructed by Kuat Drive Yards, this planetary defensive ion cannon stood as the most potent ground-based artillery offering in the commercial market in the years leading up to the Battle of Yavin 4. It boasted almost double the destructive capability of the earlier v-150 model and incorporated its own independent power source.
A particular cannon of this type was destined for installation on Mytus VII, with the purpose of safeguarding the Corporate Sector Authority prison installation known as Stars' End. Nevertheless, the prison met its end before the defensive weapon could be put in place.
