I just did this mission and I am making a video today. The key is when you begin your mission leave the area to lessen the warships detected, using silent running until only 2 warships or less are left that you detect. Fire your moss to distract the rest and fire torpedoes at the 2 (or 3) warships that are still lit. when you take them out fire your Tlams and complete the mission. As long as the remaining warships can't see you no aircraft or helos will attack you.
Problem is with this mission you can complete it but there isn't a results screen to say you did so successfully.
