Nice one. The Mysteres are not very useful, to few and too shortlegged, by the time they arrive at the scene the bandits are gone. I think Guns only, Long range loadout would work better here. Even so too few for a CAP, but i guess it is intended that way.
Yes...they might be some use, if you got lucky and had them on station at the right time to tackle some bad guys, but the French ships are meant to be mostly on their own. The Neptune, of course, can stay up for quite a while, and gives you another set of eyes to look for things, etc.
