What was the mission 11? The naval mission?
If so, anti-ship missiles, and possibly fast standard missile reload (since you'll run out of anti-ship missiles well before you run out of targets, though you can resupply but IMO that takes too much time to fly back and forth).
Alternatively, standard unguided bombs, with blast radius increasing mod, though those are less effective against ships so damage boost mod might be useful as well.
Either way, don't waste special weapons on frigates, two standard missiles on the frigate proper (not its gun) will sink it instantly.
There is just enough air combat that you'll want a multi-role plane probably, if only for the maneuverability. The Super Hornet and Su-33 are pretty good options (or maybe F-2, i've never flown that though) if you're still early in the aircraft tree, those have LASMs available. Mirage-2000 is another option.
You could also use land-attack cruise missiles (Gripen, Rafale) but if they get intercepted by CIWS, you'll be frustrated due to limited amount you can carry them.
EDIT I forgot that UGBs aren't common in early game, except for A-10 which isn't too useful in this mission (long distances, air combat). If you have the F-4 Phantom pre-order DLC, it is reasonable option.
Guided bombs should work as well but LASMs are better guided weapon option probably.
