Joktala beam kills Wraith Hive Ship

The Joktala-class energy weapon is a concentrated, yellow/green beam that fires from a capacitor that stores the massive amount of power needed to operate the weapon.

The Ancient Defense Satellite System utilized the same Joktala weapons system as Atlantis employs, with the major difference being available power. The Defense Satellite must charge its capacitors before battle, whereas Atlantis's Joktala charge directly off the city's potentia, requiring only a handful of seconds to fill each weapon's capacitor.
