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 an unshielded Puddle Jumper with two shots. The energy weapons on Hive ships are much more powerful, capable of depleting the Asgard shield of a Daedalus-class vessel in twenty minutes. These weapons are not a sustained beam like those on Ori warships or Asgard plasma weapons, instead firing in short bursts with much greater frequency. (SGA: "The Brotherhood", "The Siege, Part 3")
With the immense extra power provided by a ZPM, Hive Ships are capable of growing a far larger, incredibly powerful version of the standard energy weapon. These blasts are powerful enough to deplete the Asgard shielding on a Daedalus-class vessel with ten consecutive shots. Their power is so awesome that they are capable of actually depleting the shields on an Ancient City-ship, something which is virtually unheard-of. Since the Asgard and the Ancients possess the most powerful shielding and weaponry by far, this is truly remarkable. (SGA: "Enemy at the Gate")
