Excellent work. But soviet submarine need reworked. For example - sich conning tower was before WWII, but all boats SHCH class during WWII have standart conning towers only. And more. Submarine was have 2 45mm guns. In screenshot I saw 1 20mm Oerlicon in fore position only. 45mm guns have in Liliput library in link:

Sich conning tower Shch submarine was during 1933-1937 years.
