The gladius-class is the workhorse of the Confederate Central Military in my RP. 1050 meters or so in length, capable of atmosphere reentry for unloading troops, vehicles and supplies. The design in mind was for a spearhead, with substantial forward-firing and broadside weaponry, and great velocities in one general direction (as is with most human constructs, hah). Its weakness is, with the arrowhead design inspired by the Venator star destroyer, its stern. Yet it's still heavily defended. With the fall of the Nobles, the central military was re-outfitted with primary weapons that reflect from minor waves in subspace, to be cued on command to bend their directed-energy weapons to hit the enemy.
With substantial warp-drive capabilities as well, it can fare independently in case a Lighthouse network is down. Its primary role however is a support destroyer, with the majority of its forward mass filled with shuttlecraft and fighter bays. The immediate forward tip of the destroyer is a blast-door protected entrance to the landing bay that runs down hundreds of meters, connected to loading, repair and docking bays. Taking an ingenious tool from BSG, the destroyer utilizes modular launch-tubes for its carrier role, to deploy fighters swiftly and safely out the angled sides of the vessel.
I'm on a roll here, but I'm taking a break from paint. XD
A paint-make of the refitted Centurion battlecruiser of the Confederate Central Military. 1725 meters in length, it is a behemoth who's primary role is to protect planetary installations, engage in ship-to-ship combat and remain as command vessels behind the front. Forward and below the primary observation/command tower is an open-space repair dock for corvettes and frigates. It has vast holds for supplies. Incapable of atmosphere reentry however, it still bolsters a heavy supply of starfighters in its port and starboard 'fins'. On the ventral view of the vessel is an elongated scanning tower to map planets with great detail and efficiency, as well as provide a large sensor arc around the ship.
Armed to the teeth with large dorsal and ventral broadsides, the battleship also supports six long-range turrets which fire high-energy projectiles that, depending on yield, are capable of traversing the warp fields. Next to those are two forward-firing cannons that draw from the vessels capacitors, charged from an antimatter reactor tied into eco-point modules, which favorably draw from blue and yellow energies.
