My carrier was hit with a 600lb bomb that went thru the flight deck, through the main deck and exploded below starting a fire. Nearly crippled my carrier. I also had a dud 1000lb bomb hit the deck of my cruiser, it didnt explode, but it penetrated and my cruiser sunk because of the hole it made. Granted, the cruiser was already severely damaged, but this was just the hit that sent it to the bottom.
The damage modeling in this game is detailed, complex, well thought out and I love it.
