Please confirm or correct! S-18 on the surface can just attain 13 kt and while submerged with 4 50 cal deck gun is barely capable of 9kt. Don't know yet about S-18 with 3 50 cal or the S-42!
I'm currently driving Gar class. Would a stern 4 50 cal improve submerged speed??? Maybe from 8.75kt with bow position to 9:9.25kt.
