Bombers with limited ammo?

[RogerBacon]

I was thinking of ways to make bombers have limited ammo so they act more like WW2 bombers or even strike aircraft today. Right now fighters just feel like little satellites that fly around pew pewing the target. I want bombers that hit hard once or twice and then return to re-arm.
I was thinking it might be possible to do this by modding weapon damage, weapon energy required and energy recharge rate. If we set energy recharge to zero then the bomber would probably return to its carrier when it was out of energy. This thought just occurred to me while at work so I don't have the fighters file in front of me. Off the top of my head I don't recall exactly which fighter stats are moddable.

[Edit]
Looking at Fighters.txt energy recharge rate is not one of the settings. I was thinking of shield recharge rate. So, forget it.
