Jeff if one hit the ship we are seeing it was topside and went through the deck. That alone would do significant damage to a limited area accounting for the stained discharged ports. If it didn't detonate it still could have wreaked a few hours havoc on support systems. The could have taken a hit that still left them mission capable. If they used hull numbers this would help a lot LOL. I know what water Discharge ports look like and what Ventilation ports look like. That one is for water or sewage etc. Ships use sea water for many operations as they eliminate the need for air cooled radiators, Condensers, and other equipment that would be air cooled. Heat on a ship especially one with electronics is not a welcomed thing. We even used water cooled condensers on our ice makers.
I am doubting that these particular pics are post battle damage at this point...but we shall see. I believe good pics will be forthcoming from Haifa during daylight hours over there.
