Here's a thing for you to try... Mount some missile turrets on your gunboat. I have a Rhinland one with three Britonian missile turrets, and they can take just about any fighter down in one salvo. Plus, using some weapons exclusivly conserves power (Such as only activating the missile turrets, or only activating your forward cannon) so you can fire indefinately or at least a longer ammount of time.
The missile turrets are a life-saver for the capital ships against fighters. The other energy turrets are for other cap ships and such (In my opinion, anyways).
This is the real true story of rock and roll; it was not about anything more then, how to live your life, as a gangster, in sartorial splendor, and turning the world into a place where normality would never return again...- Malcolm McLaren
