Your missile seem awfully weak in terms of payload and also rather slow, which means quite a few will be shot down by PD, if your enemy mounts any.
On the other hand, your missile control system is able to engage other FACs, which my own usually can´t do. I am using them more like the PT boats of WW2, trying to hit larger ships.
This is a design I have thrown together rather fast, but it reflects the way, I usually build my FACs

I am allways torn between giving each FAC its own active sensor, or building a dedicated scout FAC.
Without the active sensors, I could squeeze 22 missile launchers in.
On the other hand, I usually form 6 unit FAC-Squadrons, so with the one above, I have a total of 96 launchers all together.
If I go with the "blind" FACs and include one scout FAC, I have 110 launchers in the squadron, but if the scout is taken out early, the whole squadron goes blind.
The miniaturized launchers have a ROF of 6000 (I am useing loading rate 1, as even a ROF of 2000 with loading rate 3 is pretty much useless IMO) so reloading during a battle is not an option. I am going for a big one-time-salvo instead.
There is neither active nor passive defenses present, as those FACs are designed to get in, hit the enemy and get the hell out of dodge.
