Looks like I will soon be involved in land combat in a big way. I have found an NPR worth subjugating. Will you guys critique these designs before I build them to make sure I don't make any huge blunders. They will not enter the systems until enemy fleets and PDCs have been neutralized.

First, I want to say that there doesn´t seem to be something inherently wrong with your designs, and they will do the job you want them to do, I just don´t think they are a very _efficient_ way of doing that job.
Your Chatham are incredible fuel-hogs :)
I modified a Battlecruiser of mine to carry what your Chatham has:

The main difference to your engines is that mine have a fuel use of 44.8%, whereas yours have one of a whooping 322% - Outch!
4.5 million liters to move your carrier less than 10 billion km? You _do_ have a crapload of fuel harvesters hanging around gas giants, I suppose :)
As for the concept of an assault carrier with FAC landing crafts:
While I see the appeal from a RP perspective (but then a lot more armor/passives should be on the FACs) I did away with the whole concept and just build 2 assault transports (6 to 8000 tons, heavy armor, space for a brigade) for each divisional transport and be done with it. No need to carry FACs around, twice the drop capacity, less fuel/maintenance needed,...
I mean look at it: You build a 26.000 ton ship, just to carry around 5 FACs with just one mission: To put 1 battalion on the ground each per run.
You build 31.000 tons of ships to do this.
You could just build a single 6.000 ton assault transport, that does exactely the same thing.

Same speed as your Chatham, heavy armor, some shields, ECM and the capability to land a brigade on a planet, all in one packet at a fraction of the cost of your Chatham.
If you realy want to stick with your assault carrier, I would at least do away with the troop transport bays on the Chatham and make it a true assault carrier, i.e. it carries the FACs and nothing else. The FACs take the troops from the Liberty and ferry them to the ground. This would allow you to either make the Chatham a lot smaller or carry a lot more FACs, so you can drop more troops in one go.
The Oil Company is a military design. Just pointing it out. You will need a 92.000 ton military shipyard to build it.
Not sure why you need troop transport bays on this one. Everything else seem commercial, so if you drop those, it should become a commercial vessel
I´d also reduce the deployment time on the Agincourts as I don´t think they will hang around outside the hangar bay for a quarter of a year ;) two weeks should be plenty.
That´s it for now :)

Thanks for the input. Actually, my fuel harvesters outnumber the rest of my fleet combined. I guess I need to seriously look at fuel efficiency.
I did not realize that FACs could load troops from my Liberty ships directly. If I don't need troop transport bays, I don't need the Chatham at all. My hive class FAC carriers can carry 12 FACs and they are faster with good defenses.
Anyway, I took your advice and came up with this as a close analog to your shuttle.
