Another update. I'm moving onto the main superstructure now.
Also, some thoughs about armanents if I were to HP it.
The sheilds recharge very fast, and are capable of withstanding a bombardment by four lances simultaneously without much trouble. Five will drop the shields. This will be achieved through high recharge rates.
The gun batteries will fire bolts as damaging as a lance strike, but eight or so times as fast. They'll miss most of the time at long range, making them less powerful than lances, and hit more frequently than lances at short range, making them more powerful.
This will make it very difficult for one ship to damage another of the same class except at point blank range.
Once the shields are overwhelmed, the ship will be very vulnerable to. One hit from a Lance or Gun Battery will disable a system, a second will destroy it. It will only take about 30 hits to destroy a ship with no shields.
If a ship with its shields down gets out of the line of fire, its shields will be restored pretty immediately.
The sort of Starfleet firepower required to down a shield would be of the order of ten quantum torpedos simultaneously. The Lunar class would then only be vulnerable for a short period of time before restoring its shields.
The strength of a Lance would be equivalent to two quantum torpedos, and much more rapid firing.
A Lunar class has next to zero rear firepower, and handles like a Super Star Destroyer, but Imperial doctrine is to field them in pairs or more at least.
That would provide a very toned down version of the sort of combat found in the table top game Battlefleet Gothic, but I think it work quite well for BC. (assuming BC can cope with 45k polygons per ship). Given that it would probably take 60 quantum torpedos to destroy not counting the ones neccessary to lower the shields, it could probably take on a fleet of 15 sovys and win.
I'm going to have to make some Cobra Destroyers now, they're about warbird sized, would be a better match for a sovy or two.
