List of submarines by upgraded maximum stats/New

Advantages and disadvantages:

• Submarines can only be attacked by destroyers, light cruisers, torpedo cruisers, aviation battleships/cruisers with seaplane bombers, and light aircraft carriers. In addition, they are prioritized to attack submarines first, meaning your other ships can get away with no damage done to them for free.
• Submarines are also the most resource-efficient class in the game, they cost almost nothing to deploy/repair and, in addition, make excellent, cheap additions towards multiple expeditions that utilize them.
• If you have Type A Ko-hyoteki, you can put it on a submarine for a pre-emptive torpedo strike before the shelling phase. After you get a submarine to level 10, they'll have that initial pre-emptive attack without any equipment at all. You can replace the equipment with regular torpedoes or turbines to increase their low evasion.

• You can equip SS(V) with SONAR equipment to boost the accuracy, make SS(V) more dangerous in night combat. However the bonus is some time too small comparing with torpedoes.
• But with the 53cm Submarine Bow Torpedo Mount (8 tubes), and SONAR, you can increase the hitchange of sub as well as allow them to preform cut in attack, this tactic is only viable for remodeled SSV as they can carry 2 equipment at a time.

Highlight note:

• Green: Outstanding
• Yellow: Above average
• Since the Luck Stat is difficult to modernize, it is listed as Base(Max).
