Well, the Caspar system also had actual warship drones. I think they could also theoretically follow remote orders?
So, pretty decent, all things considered. Low maintenance if just lying around, too - no internal atmosphere, no ageing crews, no need for food supplies, no training exercises.
I think the game is just not focused on naval engagements. You also have silly construction rules, including those ****** cost multipliers (Fasa-nomics), and you also never get naval versions of the new ground weaponry. Plasma, TSEMP...
It's really just a backdrop for the scenario. But then again, in the fluff there's not many warships anyways, so where would those new, more modern weapons come from?
Sides, we do get bracketing, so accuracy bonuses on the weapon would be overdoing it.
