Help! How to destroy SAM?

[superd]

Just killed it 3 minutes ago on 1st try. All my pilots die after firing all missiles and torpedos towards Sam, which had little effect. Fortunately its shield was depolorized for a few seconds and my MS did it some harm. then it regained all shield and armor and MS must give it another round of bombardment. Luckily some of my allied fired some missiles to it. So before it destroyed my station it was killed by a last missile fired by my allies and the game ended.
