Are you running any mods ? The escorts and aircraft aren't much challenge even modded, but if you're running stock they're even less so.
But even stock can be made much, much better. In fact, due to some minor escort changes I've added (but didn't do the actual work in creating the info.) to an install some of my most fun in terms of more challenging escorts, campaigns have been with a stock base including the current one.
The aircraft are a lost cause regardless.
