I would exchange one or two fire controls for more launchers, currently you have 2/fc, but you will probably need more like five of your AMMs for every targeted ASM of the same tech level.
The ranges of your missiles are a lot longer than your detection capabilities against the usual missiles, but I guess having a few longer ranged ones for emergency use against ships is ok.
10k km/s ASM = 52 % hit for one AMM
20k km/s ASM = 26 % hit for one AMM = 74 % miss for one AMM
0.74^4 = 0.299 = 30 % miss for 4 AMMs
0.74^5 = 0.222 = 22.2 % miss for 5 AMMs
If I am counting it right there is 30 % chance to miss when shooting at 20k km/s ASM with a flock of four Sonoras/Barandas of current level.
For 5 AMMs it goes down only to 22.2 %. Chmmm.
Yes, those AMMs need more work but first let's tweak the launcher ship. What about this?
Removed 2x shield and instead of 5-10 MFC/launchers used 4-16 ratio. HTK still at 99, with 4/6 magazines though 2/9 were possible too but 16 magazines seemed like too much for such big ship.

I have just noted I forgot to shield these engines but as I have already managed to put them into several designs... meh, will fix next time.
