I just want to point out that World War II submarines had great capabilities for surviving depth charges that exploded nearby while submerged.There is close to a zero percent chance that it’s not damaged, now wether the damage is repairable or not we don’t really know and in this photo they don’t show the stern where the damage would probably be
That said, I believe these survivability capabilities have been retained, perhaps even enhanced, on modern submarines.
Therefore, my position is to wait and see and not make assumptions today about possible damage, certain damage, or no damage at all.
