Also, custom mission carrier AI lurvs LCAs. Stick a few in there and its all LCAs all the time baby!
My other theory is that the Campaign mode carriers have very few fighters available and tend to try to conserve them. For the most part my carriers, starbases, and stations field squadrons of good size... but, still.
Also I have a starbase exhibiting weird behavior. It launches a single patrol, then like 2-3 other flights that take off and begin landing immediately. Sometomes one of the flights goes to orbit and immediately back down.
Station7's (the Mil-Lab) fusion reactor is very vulnerable to ship death explosions. Just a note.

Also it'd be nice if the AI packaged Heavy Ship Strike against Destroyers and Frigates. Mainly because the attack craft rarely turn to engage fighters hounding them anyway without player intervention. *g*
