Now we got those comments out of the way, a genuine criticism.
Royal Dragon Arc;
It does not have enough firepower for something of this size. While that tracking speed of 100k km/s is nice on those 80cm guns, I suggest moving down to 50k km/s as that is a lot of wasted space on turret gears. Also, those gauss should be in turrets as they are currently tracking with a speed of 803 km/s. If you have sorium harvesters, you should have enough to fill your tanks within a year or its not really worth it. For something of this size, you realy could save some space by setting deployment to .5 or .1 months and adding a recreation module. While engines should be smaller in ratio compared to "small" ships, you should still have 20% of the mass as engines at a bare minimum. You lack missile detection sensors, and while CIWS and shields will halt most missile attacks I've seen waves of hundreds of missiles that do 12+ damage each spaced about 30 seconds or so apart, so any extra defense against them is wise. If you are using a certain size missile launcher, there is no reason you should't be using a missile that could fill those launchers (shooting a size 5 missile from a size 100 launcher is just a waste and not a good idea). Despite the size difference of the launcher and missile, they can only ever shoot one at once. Also, that missile sucks and any tech level enemy can swat down even the largest of waves of them. Missiles at this tech level should be going at least half the speed of light (150,000 km/s), and you should easily reach near light (280,000 km/s or so). You need a fire control for every type/system of weapon, one for the laser turrets, one for the spinal, one for the meson, etc or else they simply will not function. You should also tailor the fire control to the weapon system as at this tech level they are stupidly expensive (ie 4x speed 1x range for gauss, 1x speed 4x range for the big guns).
King George V;
Far to slow. Not enough firepower. Set deployment to 0.1 months. Why did you limit the range of the guns by using such a small fire control? Also, that tracking speed is wasted as again, its way to slow. Swap the FC out for an actual one (suggestion is 1x range, 2x speed, fighter only), add more engines to make the engine tonnage equal 150 or 200 tons (max power engines of course), add at least 2 more guns (or swap them with a reduced size 10cm/15cm laser), remove the engineering space, and adjust everything else to neatly fit the 500 ton limit for fighters.
