MacArthur

The MacArthur is TB Dockworks's first entry into large, militarized vessels. The design takes a more traditional view, eschewing many of the augments that distinguishes their designs and provides more options for captains and their crew.

Power Generation

To keep the power low and light, TB Dockworks broke with tradition and added some missile weapons to the MacArthur. This allowed using a Torndon Abysium augmented Gateway Light power core, the minimum that could power a ship of this size. Power margin is absolutely minimal and doesn't leave much room for error.

Propulsion

MacArthur has basic Dalkinian level 6 thrusters with no augmentation and an MMW Signal Basic drift engine.

Weapons & Armament

While one would expect a huge ship like the MacArthur to have seemingly overpowering firepower, but that doesn't seem to strike quite true. Early design requirements for passive and active defenses leave the ship a little lacking in overall firepower. While it can still acquit itself well in combat, it needs a combination of ships to help it defeat an aggressor and cannot go into combat on it's own.
The spinal mount is a capital class Quantum Missile Launcher, one of TB Dockworks's early partnerships with P&G Weapons. P&G, or more formally Power and Guidance, are a stalwart but mid-range producer of active targeting weapons. 
Port and starboard mounts feature short range protective Gatling Cannons from Woochinster Enterprises. Unfortunately, these are generally not helpful for broadsides as the MacArthur is not maneuverable enough to get into a good position tactically. 
A light plasma torpedo pod protects the aft arc from long range attacks when being chased and a counter-missile bank provides short range all arc fire, again a product of Woochinster.

Armor and defense

Moderate shields from Shield Force provide some passive protection along with very heavy adamantine armor (a remnant of the conservatively defensive design requirements) and moderate Horacalcum augmented active anti-targeting defenses round out the protection for the crew of MacArthur.

Communication Tools & Systems

TB Dockworks engaged HiCray to provide a Mk 7 Duonode computer to help balance the defensive design. This does help offset some offensive shortcomings when used to supplement the weapons targeting.

Sensors

In another nod at power reduction, the MacArthur is equipped with Santoni advanced medium range sensors, not long range sensors as one might expect on a ship of this size. The MacArthur needs a screening squadron to provide long range sensors for large action coordination. While this does distribute the load and allows rapid replacement of lost sensor vehicles rather than relying on the flagship to provide the fleet with targeting and other information, it is certainly not the typical way an admiral is used to receiving battle status.

Additional & auxiliary systems

As one might expect on a ship of this size, it has a medical bay, brig, luxurious guest quarters functioning as a flag bridge and staff quarters, gym and HAC recreation suites for the large crew, a hydroponic garden and breaching and drop pods for close quarter boarder actions.
