Sorry for the delay. I've been busy installing Halloween decorations, actually. But anyway, here's my answer to the military starbase. Which I just realized contains some actual military starbase parts.
The tried-and-true Redoubt-class interstellar artillery station is an indespensable part of the PHC's military backbone, serving to support both large-scale naval engagements and planetary defense operations since the early days of the Arbiters' Crusade. Large enough to support approximately 150 Human Navy personnel and yet small enough to avoid the exorbinate costs and logistical entanglements that excluded more formidable feats of engineering such as the Shruiken complex from widespread deployment, the Redoubt is designed to operate somewhat removed from direct combat engagements, relying on the front-line forces it supports for protection. The outer ring itself contains shield generators, munitions depositores, and mechanical equipment that services the station's large weapons batteries. The eight large resupply hangars are incompatible with newer, large-scale cargo ships, forcing the station and its servicers to rely on shuttles and airtight container launches. Each node is equipped with two omnidirectional swivel turrets- RA9 Tri Quantum Rail Cannons on the dorsal surface, and Rayomax quad pulse blasters below. A dedicated fire-control center is equipped with a long-range communications transciever to manage targetting requests and one of the few weapons emplacements for use by the station itself, an omnidirectional repeating gravity gun. Connected to each weapons node by armored umbilicals is a central control section. The apex of this structure is occupied by a master command and operations center, while the ventral surface is dominated by a quadripartite reactor core- each chamber provides one weapons node with the energy needed to sling ultradense projectiles several thousand times the speed of light. In addition to barracks and crew facilities, the core provides hangar space for a squadron of single-person fightercraft, usually Nalex- or Quartzite-class. These are generally used to defend the station itself, but FTL=capable models are sometimes deployed as supplemental attack craft in nearby engagements.
