The two mines (1) are fixed to the front. They are held onto the SLC by metalbuckles (4). The mines are hung under enemy ships by wires trough the screw eyes (2) and the detonator mechanism (3) activator. (5) Tiller (steering rod), which are connected through wires (6) to rudder (7) and and stabilisor (8) controlling the SLC. Console (9) with compass, depth gauge and libelle (measuring angle) Also in same console there is a voltmeter and ampmeter indicating the engines load and consumption. (10) Lever by which the pump (13) is operated controlling the buoyancy and trim by moving water between ballast tanks (11) and (12). The revolutions of the engine (14) can controlled by a wheel over the regulator (15) which controls the supply from the batteries (16). Between the frogmen there is a container of air for buoyancy while sailing at the surface (17). In case of a rapid descent is desired a valve (18) is opened whereby the SLC dives. For surfacing the buoyancy can be restored with air from from the tank of pressurised air (19). The frogmen who are subject to a considerable force from the water while sailing are protected by a “windshield” and their legs are held into position by stirrups (20). At the rear there is another buoyancy tank (21) compensating for the weight of the engine and a toolbox (22) with wirecutters, clamps etc.
