You have to admit the ships exploding are done very well in this game. I sunk a large freighter. One torp in the stern and another in bow. I surfaced to finish it off with the deck gun. There was one small explosion and then a large explosion. The whole aft section lifted out of the water in unison with the second larger explosion, she broke in two and settled in the water. Down she went. Quite believable explosion and sinking
The devs get a great big

for this part of the sim!
