It seams carrier op is not covered in any way on latest beta patch. Corect me please if Im wrong.
I have myself enjoyed the presentation of fighters.
If you are looking SW style fighters, they DID have some independant capability, and this does not match. [But then even the Empire's T.I.E. fighters did not have much capability beyond fleet defense]
If you are looking for Star Fleet Battles style fighters, I think Distant Worlds are on track... that is just my opinion.
SFB had a fast attack craft called a PF which has roughly the capabilities that you may seek. You might be able to accomplish that by taking your escorts and then REALLY downsizing them with a minimum of weapons and fuel, and you would have that rough capability. I did that myself.
[Thank God for IGARD and his idea of designating one extra ship set as extra hulls for these classes. That is how I am able to keep all these ships with different capabilities straight.]
