I remember playing a game called 'AEGIS' (IIRC) and I'm fairly sure there was at least one other game based on the CG-47 class.
I had a ball run-and-gunning the Tico to defend the British Task Force off the Falklands. Did pretty good until I ran out of Standards and couldn't leave to restock that required me to defend Falklands Sound with Seacat and Sea Dart.
'Realistically' (frustrating as hell) I couldn't set deeplane missile traps to the West of the Islands and my SHAR support was very shortterm pitiful however so I ended up getting hosed by and airforce that must have been closer to the Russians than the Argies in size...
Had to go to the 5" and CIWS far too often (don't think they modelled Slick-32 or RBOC?) and that got me dead because it had so many flip-to-on safety and command tracking cue settings and not much accuracy (IMO).
The game's two biggest problems were it's agonizing diskaccess and it's lack of decent graphics.
It played like an ACMI screen with 3D vector-trace graphics highlighted with the odd bit of colorized dirtscape but things like SAM intercepts were a SINGLE sequence of (airframe type doesn't matter) missile-range cine photography that could literally slow a 386-33 or 486-25 (duuuh, I think) to a crawl for minutes at a time while this tiny (by todays standards) clip loaded. Two or more at the same time and you would likely crash the machine.
Added to this, the thing had limited precontact maneuver options and only really proceeded in 'realtime' with with upwards of 3-4 minutes of this-formation-that-formation delay (when the attacks did come, they came fast and furious however and Canberras seemed to close nearly as quick as Daggers...).
About every other extended engagement, the beast would dump my machine completely and so once I finally beat the Falklands scenario (and went to some naval yard for a refit with Mk.41 VLS prior to the next campaign) I got mad and took it back.
The thing I'd like to see more of however is the 'triple threat' with ASW, ASUW, AAW all integrated and coming at you at once, possibly to include TBM and cruise 'theatre wide'.
That would let you use the AEGIS system as-intended: via datalink as a battlecoordinator for AAW.
Also the ASW/AAW elements of modern helo warfare just aren't really well replicated (drop a line of active/passive buoys, get a bearing line, and 'L' the bracket with a new line until you could triangulate (an 'expert mode' would also include at least a semidynamic thermocline '3D' effect) and then MADman him and drop a flare so a P-3 can come in and lay down a Mk.46/55 or B-57 KABOOM!.
Or have the helos scuttle about forming false targets and giving the real vessels time to turn-off the expected bearing dump a decoy or chaff cloud and then come back to course from-under to unmask their terminal defense weapons...
In that way, you could do say a whole /class/ of light-vessels: Arleigh Burke, Spruance/OHP, maybe an ASST/ASW airframe (Atlantic, V-22, Nimrod, P-3, S-3). AND the 'bad guys' with PCI/FAC/PHM/Hovercraft/DDG of their own (replay of Vincennes with you as the Iranian gunning for the U.S. Navy...;-).
Again, the AEGIS system serves as your primary datalink handler and 'skipping out' to the outer pickets for certain mission segments, as needed, (kill the SSK/SSN or shortstop the PCI/FAC or whatever) you have AI warfare officers (on different ships) of varying skill control the battles you're too busy too.
