Go to a 21 space battles on the orbital. The key to success is always get an enemy ship further from other ships (the ship will lose all protection of other ships) and until right now to destroy it. The advantage also is, that even during very close fights you cannot crash into another ship, you just simply fly in a layer above. Have fun.
