My trick for the ST final mission is to fly a Zeus armed with Interceptors, Phoenix, and Tsumanis, then PromS & Banshee as primaries. As the station is going down, make sure to give either the "Ignore my target" command, or "form on my wing" to try to get them clear of the explosion. Order all bombers to attack the Hades, while you order all the fighters to cover the Orff when it jumps in. Prioritize the Zeus bombers heading for it. As the number of friendly fighters goes down, you may have to divide your time between covering the bombers and covering the Orff. Keep this up and eventually the Hades should go down. When you get moment, use your Tsunamis on the Hades' nearby turrets.
