While the second sector of Astragon's Navy had most of the powerful fighter craft, a few were deemed necessary to defend and support capital ships. The TIE Devastator was one such ship. This ship had a total of ten weapon mounts. The outward four were heavy blaster cannons, while a pair of chin-mounted ion cannons made it more lethal. This combination of weapons allowed it to lead starfghter squadrons with surprising efficiency. The other four protrusions on the wings were actually advanced sensor antennas, not weapons. Most pilots could not tell the difference, however.
