Asteroid Defense System cannon (Earth-2124)

Asteroid Defense System cannons (abbreviated as ADS cannons), are mass driver-operated delivery systems, used to eliminate asteroids and hazardous objects before they can do damage to space stations.

History
In December 2553, Isaac Clarke used the Ishimura's Asteroid Defense System cannons to fire at debris coming from Aegis VII while the ship regained orbit. Clarke later used another cannon to destroy a xenomorphs coming into the direction of the ship.

Specifications
ADS cannons are made of two separated barrels, commonly found on planet cracker ships and space stations. The weapon's goal is to automatically track down and destroy debris, mainly asteroids as the name applies, in order to prevent damage and collision with the ship or the station. Despite being automated, ADs can be manually manned, however, at the cost of the hull integrity. Multiple consecutive shots risk overheating the weapon and putting it to rest for six seconds.
