• The torpedo protection reduction skill is NOT mandatory and depends a lot on how much you use the torpedoes. Do keep in mind that even if you don't use them often, the 10% increase is pretty significant. You can swap this out for whatever you like better (for example the flak reduction if you are not as confident in dodging flak)
• Whether you use speed or HP in upgrade slot 6 is up to you.
• Using the legendary upgrade (slot 6) puts extra emphasis on your already incredibly powerful DBs at the cost of making other plane types slightly weaker, which is quite good in practice because Midway DBs are effective against all surface combat ships.
• Ovechkin is highly recommended because of his improved SE. See here for a ship priority list for this captain.
• Applies to Langley, Ranger, Lexington, Saipan, Sanzang, Enterprise and Midway.
