Well, nukes for us deal standard damage, so... uh...
Eh.
I believe you are accounting for the overhead of the ASF, but not for the overhead of the station.
Actually, just for the fighter vs. missile ammunition. A single missile is 8000, a fighter is 5m. The fighter costs maintenance, the missile doesn't (unless you shoot 50% of them every turn).
I actually think missiles are rather unsuited to battles, but if you manage to win, they are
very economical.Otherwise, I agree---naval weapons are the preferred choice for naval ships.
I don't actually have a problem with that, but that sounds a little too pointed for my tastes. ;)
To take a real world marine analogy, actual battleships had big guns that were unsuited to effectively fight small, nimble destroyers, torpedo boats, and obviously aircraft. Sure, they were devastating when they hit (unless the target was so light and small the shell just smashed through without detonating, which happened), but they were hard to train on target and hard to shoot in on something that could change course quickly.
So those ships had a secondary battery of smaller guns. And sometimes torpedoes and AA armament that we can ignore for our medium is different.
For role specialization, there were those lighter ships, with lighter guns, which could hit lighter ships.
But in our case, the best choice for pretty much every ship seems to be to increase the main gun battery, on all the ships, every time, and then just use some lighter guns to fill the remaining space on deck when the remaining displacement isn't sufficient to mount yet another gun.
Which does sound like some ships of past centuries. ;D
