Point defense is the practice of actively defending a single ship against attack from a specific vector, as opposed to fleet defense, which seeks to defend all friendly ships in the vicinity, or area defense, which intends to counter all threats in a given area. The most common expression of point defense in Nova is an automated, turreted weapon system that tracks and attempts to destroy incoming fighters and missiles. Examples of point defense systems include: * Storm chaingun * Quad light-blaster turret
