There is a HUGE difference betwwen original and remodeled submarine. A fact that the SS becomes SSV after remodeling does not matter much. Unless your trying something specific like submarines vs submarines with autogryo and ASW plane, your SS will most likely be equippped with torpedoes.

A single torpedo alone can't trigger cut-in, and 2 or more torpedoes will let your subs to cut-in. And these torpedo cut-in is what makes submarines and most of destroyers DEADLY in night battle. Even the strongest, toughest ship like Yamato class or some boss ship from Abyssal fleet with their health gauge full will be knocked out by shot from torpedo cut-in attack.

So far, I've never seen a torpedo cut-in attack missing its target. I dare say a torpedo cut-in attack is a 99% guaranteed 'one more enemy sunken ship'.
