The Castle-class Drone Dreadnought is a true *behemoth* of a ship, as big as two Onslaughts put together, this titan of the Domain's secret automated warfleets was designed with agression in mind, with it's myriad high rate-of-fire weapons and burn drive, the Castle is meant to ram into enemy formations and unleash countless munitions in every direction while they are disorganized.
The Garrison-class Carrier Drone is something of a filgap ship made to compensate for the lack of carrier support within the Domain's drone armadas, being basically just a Rampart drone with it's missile systems gutted and replaced with internal manufactories for producing expendable drone fighters, it's not the most impressive carrier, but it's relatively fast and can quickly replace losses from it's two drone wings.
The Barracks-class Carrier Drone, however, is a much more permenant solution to the Drone Armada's carrier problems. Being based on a fully-automated version of the Mora hull, the Barracks can carry a full fighter wings- thanks to not having to worry about pesky things like 'crew quarters' or 'life support', however, much like the hull it is based on, it is rather slow, and thus functions as a dedicated support carrier to the Garrison's light strike carrier.
The Crenelation-class Fighter Drone isn't much by itself, but it's dirt-cheap to replace and they come in massive numbers, and can easily carve a careless ship to peices for underestimating them.
The Embrasure-class Bomber Drone is a slow, clumsy and not all too durable thing, but it's torpedo payload is devastating, letting a horde of these things get close to your ship- reguardless of size- is a surefire way to find your hull full of holes in short order.
The Stockpile-class Logistics drone is a simple, automated logistics ship designed to keep the rest of the armada flying and as such is an all but unarmed wallowing sow that requires defense from it's fellow drones if attacked. Generally kept well away from the battle.
The Seige Tower-class Assault Lander Drone is perhaps the greatest symbol of the Domain's iron fisted grip over humanity. A fully automated planetary assault vehicle loaded to the brim with ancient tank drones, mech drones and aerospace drones, this monsterously illegal war machine is capable of landing and commanding an entire four batallions of combat drones in a planetary invasion... albeit, in a very pre-programmed and uncreative manner. Best used in vast numbers.
The Ram-class Phase Drone is a rarity among the Domain's secret armadas, with the far-less developed phase technology of the time, phase ships were far from the monsters that they are today, and thus the Ram was relegated to a role of disruption, phasing into enemy formations and causing chaos before- hopefully- phasing out again.
