The first turrets to have a shield capability, these defences are regarded, at least in the earlier stages of the game, to be a strong deterrent from attackers. Many players also cite their efficiency at luring fighters into attacking them instead of fleet ships as a reason to keep them up even after much higher level defences have been built. However, there are reports that the fighter luring capability no longer exists due to game mechanic changes to the combat formulas. Even though classified as an Ion weapon, these turrets DO NOT gain a 50% bypass to enemy shields.
