AEGIS

AEGIS stands for Automated Energy-based computer-Guided Intercept System. (Keep in mind that AEGIS and its definition are the human terms for it, every race has their own term for it.) It is the point-defense system used on almost every ship in the galaxy. It is a network consisting of multiple mid-power laser turrets with the purpose of destroying incoming torpedoes and fighters.

AEGIS systems are usually run by a Class-1 AI, which reduces crew requirements. Human ships do have Class-1 AIs in control of the AEGIS system, but manual overrides are available.
