Keep your ships all grouped together close to the station and let them come to you.
Your ship is carrying long range Artillery, the Battleship is very slow, so send out fighters to distract the AA beams and slip as many missiles through as you can, your partners can keep the other ships busy. The base is loaded with Fighters, which also helps you somewhat.
Be sure to target subsystems, that's vital in this game, you can paralyse a ship long before you destroy it, aim particularly for heavy gun points, and try to keep a unit of fighters in case he tries to do the same to you, though that isn't always possible.
Once your in close combat, select all large ships (Except the Angelwing) and pound the Battleship into submissions, the base and it's fighters will cope.
The next problem you have is the commando transport launched by the Ming, the best trick is to just ignore it, with you all clustered round the Angelwing (which you should have sent to the base at the start) It's highly unlikely to get through, but just in case, send any fighters you have left on 'guard' around it.
Hope that helps. And yes, I agree about the weapons.
Edit : This is a 'fine detail' game, remember you can do stuff whilst paused, particuarly, target certain ships with certain turrets.
