What are playing stock or modded? I will assume stock seeing as most mods give a nav mode button to learn of your max range at current speed.If you stay at ahead 1/3rd you should be o.k. to get to Midway if you are in Japan/Northern Pacific if you are based out of Pearl. If your running from Western Australia you should be o.k. as well so long as you go slow.

I'm pretty sure with 25% you should just be able to get back to a port from 1800 nm but it might be rather close.Try to avoid diving you'll want to avoid having to charge your batteries not sure what eers75 is thinking with his advice charging batteries consumes more fuel than staying on the surface even in Stock SH4 though I think that trick will work if you have a short hop to go like a few hours from port if you are trying to realistic that technique would 100% be cheating that would not work in a real life WWII submarine because you'd be consuming easily double the fuel that way vs. surface running so once the batteries where fully drained you'd consume all your fuel trying to recharge them.According to TMOs nav data your max range at given speed goes down drastically while recharging batts which is accurate.


I recall making it from off Okinawa and getting to Midway once with around 30% and that is around 2000 miles or more.This was with TMO though.By the way if your Running RFB or TMO
go to the map room page and one of the buttons will have the nav officer tell you your max range at current speed you'll get your answer for sure then stock its a wild guess but I think you can make it.

Anyway good luck I'd give you a few gallons but currently in the Asiatic Fleet so that is a no go.And it would cost you a lot of Pabst Blue Ribbon.
