Drone Command LACs are (insert latest or near latest LAC type preferably from Manticore) LACs that are just a plain LAC, but with way more EWAR capability, way more Point Defense, and thicker Sidewalls, Bow Walls, and Stern Walls. They may even have their GRASER stripped out of them to replace it with more point defense and EWAR emitters. Drone Control LACs (DCLAC) are built to control Drone LACs. They have high powered Gravitic FTL communications systems, and way more command and control links, providing a real time long range missile, energy weapon, and drone controller at a great distance form the mothership. They are designed to hold up to 25 crew members and are built to be more survivable than any other LAC. Their EWAR suite and Point Defense systems would be heavier than even some Destroyers and Cruisers. They would have no missile launchers on them, but instead would replace any missile launchers a combat LAC would wield with Counter Missile launchers galore and more Point Defense. These would be strictly designed to survive a relatively tough engagement at ranges that were closer to the enemy, and command and control Drone LACs. They are not designed to attack directly, but be a command node for multiple combat attack systems. This would extend the range of the CLAC’s attack capability, and also give the CLAC commander an ability to station massive EWAR and Attack Salvos in multiple directions around a given area. These ships and their Drone LACs could also be used to “hide” their Carrier in the shadow of all their Wedges, like a massive smoke screen, at greater ranges, without sacrificing Destroyers. They could also be used to shore up small missile sized gaps in an Anti-Missile Defense Formation’s Wedge “Wall”.
Drone LACs are what they say they are… Drones. Take out ALL of the life support, take out all of the crew spaces, take out everything that a human needs to survive inside a LAC… and then fill that space with more weapons, point defense, and/or EWAR equipment. Shove a nice powerful computer into it, and pack it to the gills with attack and defense stuff. In fact… once could build 2 variants. One is basically a normal LAC minus the crew areas and plus more of everything stated above, and the other is basically a Missile Pod with a Grazer mounted in the middle of it, Node Rings bolted onto the outside of it, and some Side, Bow, and Stern Wall generators and Point Defense strapped onto it. The second one is more that that, but basically it’s that. Take a LAC hull, and gut it of all LAC sized missiles. Keep the GRAZER in the middle, rip out all Crew spaces, and fill every available space with EWAR and Point Defense systems. Now… where the LAC missiles typically sit… replace that with the missile tubes found in Missile Pods, and point them along the same axis as the Grazer, as they’ll probably be about the same length… now wrap as many of those tubes around the Grazer array as is physically possible. Viola, mobile Missile Pods, with on-board protection against proximity soft-kills, that can be used to attack ships at close range like a LAC, swung around and rolled to protect other ships behind them with a wall of Wedges, and that have the added nasty surprise of actually just BEING a LAC with giant Grazer in the middle, and all controlled at a distance by individual Drone Command LACs. They could also be automated somewhat as well, so that they can carry out programmed attack runs on their own automatically when a certain parameter is met… like their Command LAC being destroyed, so they acquire the enemy ship they were being targeted on anyway, and they go and attack it without further orders. These ships could also reduce the needs for Grav Plates, as they no longer have humans aboard them, so all Grav Plates would be necessary for is to reduce inertial strain on the equipment and the ship.
One could even strap the Ghost Rider stealth systems into both of these ships, borrow the systems from the Recon Drones and make them for a LAC hull, to improve their survivability.
The final revitalization of drones as reality IMO are Torpedo Grasers just hanging out for months at a time waiting.
