Amphibien-Panzer: Had trials at the wars end on Sylt but was never completed. It had a fixed periscope of 1 metre in length.

Wargel: Amphibious tractor similar to the amphibious panzer. Had trials on Sylt but never completed.

Seeteufel: Two-man amphibious U-boat with its hull on a tracked chassis. It was fitted with a diesel engine with a maximum speed of 10 nautical miles per hour in the water and 8 nautical miles per hour on land. It was armed with 2 torpedoes and 1 machine gun or flamethrower. Its advantage was that no slipway or auxiliary troops were needed. Mass production was due to start after the war ended.
