The wing cannon, the primary weapons system of the death glider, is a larger version of the staff weapon. SG-1 created a makeshift weapon by cannibalizing the wing-mounted weapon from a downed death glider on P7S-441. The result was a shoulder mounted energy weapon with the power of a death glider and the mobility of a staff weapon. Teal'c used the wing cannon to shoot down the alkesh piloted by Tanith on P3X-116.
