Does PLAN have any small subs or submersible fast transport/attack boats?
Just never heard of any in Chinese service which is odd as many navies have something.
Well, in world war two British and Italian midget subs had huge strategic impact. So history isn't entirely against them.
North Korea and Iran are prime examples of midget sub operators, and have submersible fast attack/infiltration boats also. But off the top of my head midget subs are also operated by Pakistan, Croatia, Columbia.
Some midget submarines are used as swimmer delivery vehicles whilst others lay mines or carry torpedoes.
