I´d go for either a quad turret with one firecon, or keep your two twin turrets but add another firecon. As it is, both turrets can only shoot at the same target anyway (a quad turret has more hits-to-kill (HTK) than a twin, so it is harder to take out).
I agree with Thiosk on the CIWS. Ripping those two out will likely free up enough space to add a second firecon and upgrade the turrets to tripple ones.
The range of that res-1 sensor against size-6 or smaller missiles seems to be around 90.000km. If this is correct, it is way too short-ranged. An enemy missile moving at just 20.000 km/s would cross your sensor coverage within a single 5-second increment, leaving you without any chance to shoot at it. You´d want the sensor to detect size-6 missiles out to at least 250 to 300 k.
Note: If your guns are properly set-up for PD purpose, they will probably shoot anyway, still, I´d like to have some warning of incoming missiles before they impact.
Also agree with Thiosk on the anti-ship active. Range is way too short if working independantly.
On the missiles:
Now, having a MFC with a larger range than the missiles can fly is not a bad thing, as this can counteract enemy ECM, but 37mkm IS rather short ranged. You might want to put some research into fuel efficiency (Power and Propulsion) as this also increases range for missiles with a given amount of fuel.
Alternatively, reduce warhead to 7 and put the space into fuel. You don´t have to go for the full 70 mkm of your MFC, but something around 50+ mkm would be nice.
The shields are not of much use. Strength 8 means, they can stop a single missile of yours. Personally, I consider anything below 20 as pretty useless. Shields come into their own when they get strong, as they start to recharge during combat.
Example:
A shield strenght of 100 with a recharge time of 300 secs means, you are recharging 0.33 points of shield each second. If the enemy launches every 30 seconds, your shields will recharge about 9.9 points of strength between salvos, which would be enough to keep the occational leaker from depleating your shields.
On maintenance:
What you should be looking at is NOT the Annual Failure Rate, but the Est. Time
I am aiming for something between 2 and 3 years, personally, except for survey ships, which will be build to last a lot longer.
