Yes, I have seen many a hit below waterline with HE in my games. But does anyone know if it actually was possible IRL for a HE round to penetrate 2-3 meters of rock hard water (at the speed we are talking here...) and successfully explode upon impact with the hull? :hmm: My gut tells me that it won´t work as it does in game. However; it is still a game, so it doesn´t really matter. Any naval ordanance experts here? If my suspicions are true I will bring AP rounds for waterline shots as flavour.
