Played quite a bit with your mod, and as old starsector and 40k enjoyer i like it a lot and much!
Ships FEELS and looks orky, without copying them from existing models of og 40k, it IS how orkz stuff probably would look if they sunnedly warped themselfs in persean sector of DAoT. The ships, weapons nad systems descriptions are "cheffs kiss" and PROPA ORKY AND GREEN. Just love it.
Just a little balance rant, sorry. Some of their kroozers and weapons feels a bit op, but in a heavily modded run other slightly op stuff balances it. Still, 20 dp cruiser with Large ballistic, numerous lesser ones and enough speed to get colse and dakka enemy to death is still a bit op. Weapons have better damage (thats actually ok) and flux stats (that is perhaps not), and their *** poor accuracy (which is orky and good) kinda not helping, beacuse their ships waags themselfs in close range, where accuracy is not that relevant.
And Space Hulk should be much, much bigger. Please replace Big Capital Ship with some canon orky battleship, slow (but with Big Red Button), prow-mounted Biggest Kannon (or Rokkitz. or Megazzappa) and other bitz and gibboz size of a Onslaugt. But Spacy Hulk, imo, should be at least twice bigger supercapital. Even slower, maybe shieldless, asymmetrical as warp kitbash of a dozen of ships, and overall something in a spirit of HMI Locomotive of SWP Cathedral or what was that UAF Modular supercrap, well, BIGGA AND BETTA AND PROPA ORKY, ZOG!
