Personally, I dislike it. For my money, if you have 18,000 tons of warship you can fit more than four lasers on it. I won't argue about the speed, because while I personally would not use quite so much space for engines (1) I know many players prefer it to guarantee superior speed against the NPRs, and (2) if we're coming from behind in a conventional start it probably makes sense. I always play TN roleplay starts so my priorities are a little different.
However the fuel is simply excessive, you probably don't even need 1/3 of that range for a good warship. If you want longer range I say use tankers, this is a warship and that tonnage should be going into weapons. Personally I would also probably settle for maybe 8 layers of armor but that is to taste.
In addition to more guns I think an AUX would be good to put on, it's only 1 HS, costs merely 2000 RP to develop, gives our low-rank officers something to do, and helps with crew training quite a bit. Otherwise the design looks reasonable for the job.
I actually prefer to put at least one PD turret or a couple 10cm railguns on every ship for redundancy, you don't want to lose your PD escorts in a JP assault and then be stuck waiting for new construction because your battleships can't defend against the NPR missile salvos.
Otherwise same general thoughts about all three ships. Main thing to change is cut off a bunch of fuel and add more weapons of both offensive and PD types. We could get more firepower per ton using non-turret lasers but that's a question of taste I think.
