 Projectile Tower - NSwiki   (Site not responding. Last check: 2007-11-07)
The Projectile Tower is an armored rectangular weapons emplacement for large warships, designed to be largely self-sufficient with regards to power, and sturdy enough to resist attacks, while providing facilities and equipment for a large projectile-based weapons platform carrying kinetic, guided/unguided, and strategic missiles.
The main weapon is a "driver" or Multi-CASCG with nine standard-26cm 'barrels,' fed by no less than 3 MMATS connecting to the external missile bays.
As a high priority target, the projectile tower is heavily armored with the most advanced materials in a closely-guarded secret composition of layers totalling 1.5 meters thick in most places.
