The Schwimmkörper was a device built by Gebr Sachsenberg which consisted of two large pontoons that attached to either side of a Panzerkampfwagen 38 (t) tank.
The tanks were specially sealed and some modification to the engine exhaust and cooling was needed. The pontoons were detachable. Water propulsion was transferred from the drive sprocket, and the floats were attached on extensions to the track support rollers.
Afloat, it was capable of 10km/hr.
