However, she has a very low Dive Capacity reserve, at 120 units, allowing her to stay underwater for only 2 minutes. I-56’s Dive Capacity recharge time is improved at 2 units a second. This means diving after being spotted leaves a significant time for enemy capital ships and cruisers to drop depth charges accurately and deal damage. I-56 has very bad diving plane shift time, taking 26 seconds to fully dive and to surface. Careful positioning is vital in order to not be stuck in bad situations where her speed will not bail her out. The poor underwater speed means she is not fast enough to outrun destroyers and her hull can be vulnerable to depth charges. However, her underwater speed is slow at 13 knots. She has a good speed of 29 knots when surfaced. Her surface concealment, at 7.12km, is very bad for her tier (outspotted by almost every destroyer in her matchmaking spread). Her rudder shift and turning radius are comparable to that of a cruiser, at 9 seconds and 670 meters. I-56’s maneuverability and concealment are very poor for a submarine. Players should be careful not to be spotted on the surface for extended periods of time, as she will suffer heavy damage. Her armor is nonexistent, with her exterior hull covered in 16mm and 19mm plates. I-56’s survivability is high, with a high HP pool of 24,200. She is the first submarine introduced with a player controlled deck mounted gun. She is well equipped in terms of offense, having fast loading torpedoes and long range, high alpha conventional torpedoes. I-56 is the first Japanese premium submarine in the game.
