Well , German company HDW have accomplished concept design of bigger submarine that based on the design of U-214/212 , it's called U-216 with 4000 ton Displacement and it will have Vertical Launch System
this is why i'm asking , RATSHIP AND MOSHIP have the same primary mission which is rescuing submarines
so, what you saying , MOSHIP IS dedicated submarine rescue and RATSHIP can rescue submarines and surface ships ... right ?
