Wraith energy weapon

Wraith energy weapons are energy weapons used by the vessels of the Wraith Fleet. Wraith darts possess single fire weapons at the front of their ships, which, if well placed, can destroy a puddle jumper with one shot. The energy weapons on a Wraith hive ship are much more powerful, being able to quickly deplete the shields on a 304 in a matter of minutes. Twenty to thirty point blank shots from the energy weapons on a hive ship will destroy another hive.

The control systems of the Wraith energy weapons are possibly mental, due to the Wraith's telepathy capability, but this has never been proven true. Also, the power source is most likely something equivalent to a Zero Point Module because of the hive-ship's rather vast energy consumption of moving the hive and operating it's weapons. In Stargate, Wraith hive-ships are seen bombarding Atlantis from orbit using their energy weapons, in which their weapons can hit targets from long distances.
