List of submarines by upgraded maximum stats

• Submarines can only be attacked by destroyers, light cruisers, torpedo cruisers, aviation battleships/cruisers with seaplane bombers, and some light aircraft carriers. In addition, they are prioritized to attack submarines first, meaning other ships can get away with no damage done to them.
• Submarines are the most resource-efficient class in the game; they cost almost nothing to deploy or repair.  Furthermore, they constitute cheap additions towards multiple expeditions that can utilize them.
• Submarines equipped with Type A Ko-hyoteki will perform a preemptive torpedo strike before the shelling phase. After reaching level 10, they'll be able to preemptively attack without any equipment at all.

Highlight notes:

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