Well...that pretty much sums it up. But think about it like this:
1. Build a massive fleet of small fighter+bombers and send them out towards the enemy, the fighters keep the gunners distracted and the bombers blows them to dust.
2. Build corvettes/gunships/frigates that are easy to maneuver, don't turn that bad and can pack a bunch + if they are guarded by fighters its hard to take them down.
3. Battleships, what's better then a big ass ship firing lazers and photon at you?

add that if you have 50+ (I had like that in X3, almost made my game crash xD) then you got yourself a free light show (Disco! Disco!

)
