SX - Seeteufel

German experimental mini-submarine called SEETEUFEL (Sea Devil) or also ELEFANT (Elephant). The interesting feature of this craft was its ability to move under its own power on land, so it was able to get in and out of the water without any assistance. I don't know if my assumption is correct, but probably the basis of the chassis was based on the Borgward B IV.
There was one prototype with a 58,8kW (80k) petrol engine and the production machines were to get a 250k engine. Armament consisted of two torpedoes or mines. When moving on land, the submarine could be armed with a machine gun or flamethrower. Tests of the prototype went satisfactorily and serial production was ordered just before the end of the war.

the submarine was a bit smaller and the B4 chassis probably wouldn't have taken it here are the TTDs I managed to find (most sources agree on them.

Weight : 18 t empty, 20 t rigged
Propulsion
1x petrol engine 80pcs
1x electric motor 30pcs
Speed 10 knots on the surface, 8 knots below the surface.
30 km/h on land.
Range 600 nautical miles at 6 knots on the surface, 12 nautical miles underwater.
Depth of dive : 20m (serial machines were to have up to 50m)
Armament : 2 x 533mm torpedoes or 2 mines.

Only one prototype built, at the time from March 1944, which was captured near Lübeck at the Borgward factory. The designer was Dipl.-Ing. Alois Lödige, the project was called besides Seeteufel also Elefant or Project Lödige.
The ground motion was only to allow the submarine to drive out and into the sea, it was just an accessory to allow easier handling of the machine (no combat deployment on land was envisaged).
