Tauchpanzer, meaning "Diving Tank". Designed for "Operation Sea Lion", it was meant to be dropped offshore and travel on the seabed to the beach. They were Panzer IIIs, totally waterproofed. They had an endurance of 20 mins. and could travel to a depth of 50'(15 meters), the length of the air hose. Though never used to invade England, they were used for their intended role in the Russian invasion, crossing the Bug River. They were then used as normal tanks. More than 150 were built.

They worked okay on a river bed but the 6 to 8 knot currents of the English Channel and difficulties of navigation would have meant near certain depth for the poor crew.
