That was a warship designed largely based on the Bavarian-class battleships, designed by Tang Country designers, so the performance was well understood by the Tang side.
At this moment, this behemoth with a full load displacement of nearly 40,000 tons was turning, with even more warships moving in the distance.
"Two torpedoes! Aim at the target! Adjust the bow!" Having spotted the distant warship through the periscope, the submarine captain excitedly began issuing attack orders.
Due to the great distance, they had to launch the torpedoes early, calculating angles accurately to hit the target.
As for closing the distance, it was actually impossible; if the submarine tried to get closer, it couldn't approach the target directly, because even a single periscope tube during the day at sea could easily be spotted.
