Acoustic (Homing) torpedoes - more consistent hits, but less damage.Subs still can choose at which depth they want to be. Submarines can now choose between 3 depths (surface, periscope, and maximum depth), thus making the decision simpler for the sub commander and easier to interpret for opponents.Surfaced submarines have the ability to detect a ship that is firing in/behind smoke, but submarines at periscope depth can only detect this ship at the assured acquisition range.However, submarines can only have 1 active flood at a time, so a large number of airstrikes at the same time will not be very effective against a submarine.Depth Charges from Airstrike now have a 100% chance to cause flooding on submarines, thus dealing major damage to submarines.

The Depth Charge Airstrike now reloads faster, allowing ships to quickly and effectively react to the above two mechanics.
