I was doing a solitaire CG battle that eventually saw Askold pouring port broadsides into the starboard side of Ikitsushima from about 4500 yards while the 2 of them were all alone. At this point in time, Ikitsushima's starboard battery was totally out of action so she could only bang away (at very low ROF) with her massive forward gun. This isn't much of a threat, at least at this range, due to its long reload time making it hard to maintain a plot on a moving target. The big shells periodically came Askold's way, but landed 2 or 3 ship lengths away. Nothing else was shooting at Askold except this 1 gun. However, the blind sow finally found an acorn and that's when I saw the damage model do something really cool.
I paused the game as soon as I heard the hit sound so got to look at it quite well. The shell hit way forward on Askold's port bow, near the anchors. When it hit, it made the huge hemisphere shockwave, which as best I could determine, when looking down the length of the ship, was centered on the port side of the hull. However, the shell apparently went completely through the ship and out the starboard side right at the waterline, because it also made it's big splash on the starboard side of the ship. The splash graphic rose up right against the hull, partially covered by it, like a torpedo hit. The shell obviously didn't go over the hull to get there, so it had to have gone through.
This is the 1st time I've ever seen this well-documented shell pass-through effect modelled in a game. Always before, projectiles have stopped on the 1st surface they've met. But that's just part of the coolness. I quickly checked Askold's ship info screen to view the damage, and was amazed again. On the port side, the shell had knocked out the forward anti-TB gun in passing, and had then caused 15% flooding on the starboard side. Before this hit, Askold had only been engaged to port so had no starboard flooding. And the starboard flooding was a lot for just a shell hole, so I'm thinking the damage model threw in some near miss blast damage from the adjacent splash. Askold also lost 2 knots of top speed from this hit, which on the surface is a lot for a hit with not much flooding and so far from the engineering spaces. However, that's cool, too. Maybe the shell burst in exiting, leaving a lot of twisted metal dragging in the water. Or maybe the because the hit was so far forward, the ship was really whipsawed from the shock and that bent the prop shafts a little. Or maybe some of each. Either way, it was an awesome display of the damage model in action. I'm very impressed .
