Giorgio's last task was to go round the hull exterior to check the bow tubes.

The submarine swung around and fired her bow tubes at another ship.

Three bow tubes fired at each target resulted in one hit on each.

To maximize the odds of a hit, Blanchard fired all six bow tubes.

The most significant difference was the addition of 4 more torpedoes and 2 additional bow tubes on the type 87.

Two torpedoes left the still functioning bow tubes double shot!

Another spread of three from the bow tubes produced two hits on a heavily-laden cargo ship.

"Do you want to finish reloading one of the bow tubes before we surface, Captain?"

The bow tube was retained, but also moved below the waterline; it had three torpedoes.

He fired all six bow tubes at one "battleship".
