A hull-mounted turreted auto-weapon, drawing power from the ship's main ring to operate a short range particle weapon, the point defence turret interfaces with the ship's sensors and targets incoming missiles.
Once they come into arc and effective range (about 2 kilometers) the gun opens fire, attempting to destroy the missile.
Very fast rates of fire and excellent targeting AI mean that it is quite effective against normal seeker missiles.
This is a very useful last-chance anti-missile weapon, especially as it requires no ammunition, and does not replace counter-measure launchers.
