I am sorry, i found what i need
in Data\Submarine\EnglishNames.cfg
But i have got another question - in game we can chose two types of battaries for a Type II - Standard "AFA 36 mak 580" 7160 AH and Improved "AFA 44 MAL 570" 8380 AH
So Type IIa, historically,can go 35nm with 4 knots submerged without any upgrades. Thats clear.
But Type IIb, historically, go 43nm with 4 knots submerged. Its because of THOSE IMPROVED battaries? or its "standard" and can be upgraded with AFA 44 MAL 570????
That's interesting
http://uboat.net/technical/batteries.htm Hmmmmm
Am i correct that Type II B can do 43nm on 4knots, because of NEW economic electric engines, not batteries?!

OR WHAT???!!
And the last question Type 2B goes 3100nm with cruising on 8 knots. What distance it will go on 12 knots? Beacuse all in game are in distance\12knots. 2066 nm ???? am i right?
Well i made a huge research about all Type 2 U-Boats
And made some serious decisions
First: our ingame Type IIa is TypeIIC (!!!!!!) or, maybe deep modification of type IIa.
Because Original Type IIA & B Didn't have the second PERI!!! And the radio interception antenna were installed in the center of turm only on C & D modifications.

So i start to full rework on Type IIa in the game, for adding all TypeII C params instead of original.
BTW i finnaly found ranges at 12 knots instead of 8.
