Point Defense Cannon
A Point Defense Cannon, also known as a PDC, is a rapid-fire projectile weapon used by all military-grade spaceships for defense against small ships and missiles.
PDCs are turreted rotary autocannons, utilizing a set of six spinning barrels to spew out thousands of rounds per minute to intercept incoming ordnance. PDCs are laid out on a ship's hull to cover all angles with overlapping fields of fire, providing a point defense network "curtain of steel" to more easily and effectively take out missiles. They also utilize thrusters on their rear to counteract the recoil of the firing cannon, that would otherwise knock the ship off course.
PDCs are computer-controlled, as even juiced-up human gunners would find it nearly impossible to effectively track and destroy fast targets like torpedoes. Human gunners do, however, select targets for the guns. The cannon turrets can also be retracted into the hull and can extend outwards in mere seconds.
PDCs are mainly used against guided ordinance, but they also perform fairly well as close range ship-to-ship weapons and can be used for direct space-to-surface strikes on personnel. The rounds seem able to penetrate the armor on most smaller ships.
