Just a thought I had when destroying a pirate base. You should be able to attack installations planetside with your ship's weapons as well as send missiles (nuclear or otherwise) raining down upon your foe.
Your pilot would need to be skilled enough to keep a stable, geosynchronous orbit without any major drift
Your science officer would need to operate the scanners effectively to pinpoint a precise strike point
Your gunner would need to be skilled enough to send the payload where it needs to go
If you do a strafing run on your target, you will have to worry about any defense systems groundside as well as crashing into the ground at a thousand miles an hour and going up in a glorious inferno of death.
