The submarine comprises an immersion cell that has an opening closed by a shut-off valve that is designed fluidically controllable. A sealant of the shut-off valve is movement-coupled with a piston rod of a hydraulic cylinder (20). The shut-off valve is pre stressed in closing direction. The hydraulic cylinder is a double acting cylinder (22) that has a primary cylinder chamber (36) and a secondary cylinder chamber, where the primary chamber is pressurized during extension stroke of the piston rod and the secondary chamber (38) is pressurized during unlock stroke of the piston rod.
