I've installed NSM 4.0 by following orders:
TMO
RSRD v502
RSRD patch
NSM 4.0
When I test it in submarine school's torpedo attack tutorial I found that those torpedoes penetrated the Mogami's hull straightly like ghosts(not in the case of over-depth). I suspect that it may be caused by the alternative Mogami class of RSRD(5 main turrets)which may be incompatible with NSM 4.0 so I deactivated RSRD and took a test one more time then I found that it's no problem with stock's Mogami.
