"The long range bombardment weapon known as the secret weapon "Type 91 Armor-Piercing Shell". This type of ammunition will spin rapidly after exiting the the gun's barrel, enters the water, and penetrate the target's armor below the waterline like a torpedo, crushing the hull of the ships. The shell's shape enhances underwater penetration while also improving the range by decreasing air resistance. Available for Battleship (BB), Aviation Battleship (BBV) etc."
