I kind of agree with putting the shields in even if they are crappy ones, as it means you don't need to refigure the design to allow space for them once you get reasonable ones, just refit.
Comments on the ship.
You have a rediculously excessive ammount of engineering spaces, even by my standards. Strip out at least 2/3rds of them, aim for around 3-4 year maintainance life.
I'd up the deployment time to roughly match the new maintainance life, it means you don't need to keep track of them seperately.
Your magazine size is tiny for the number of launchers you are carrying, you only get 7 salvoes. Use some of the space freed up from stripping the engineering spaces for more magazines.
Your reactors seem really odd to me. It looks like you should be drawing a total of 36 power for your weapons, so if you are wanting two reactors to give you redundancy in case of combat damage, you will want them to be individually capable of powering the ship.
Why the two different sizes of lasers? You haven't optimised them to have one for anti shipping and the other for point defence, so it looks like a somewhat bizarre choice.
Fuel capacity is really low for a ship this size. It is sufficient for combat operations but it does mean that you will have to be returning for refueling frequently.
Your missile active sensor could do with being at least double the size if not 3-5 times the size. As it stands it will only be picking up missiles at around 140,000 km meaning an incoming salvo travelling at 30,000 km/s(and that is a pretty conservative speed for anti-ship missiles) could cross it's entire detection range without being picked up.
I'd suggest dropping the resolution on your missile firecontrol and your ship active sensor down to 60(3000 tons) possible increasing the size of your firecontrol slightly to bring it up to the same range. You at the least want the resolutions to match or you get situations where you can't spot targets that you would otherwise be able to shoot at.
Wow, you call that a frigate? Each to their own, I guess.
In my current campaign, I call a 10,000 ton ship a Cruiser. Some people do build multimillion ton super-dreadnaughts though, so it's definitely possible to have different design philosophies.
Indeed, it would be a light destroyer in my ship classification scheme.
