Germany's Panzerkampfwagen IV als Tauchpanzer

Design

42 (402) PzKpfw IV Ausf Ds converted for underwater operations in Operation Sealion.3 The engine air intakes and the exhaust were fitted with non-return valves in place of the mufflers. The cupola, mantlet, and MG mountings were covered by waterproof fabric. The driver's visor was altered by using a metal cover with a vision block that was water tight. A rubber tube that was inflated went around the turret ring.

With the modifications the Tauchpanzers could operate in water up to 13' in depth.3

Usage

Used by the 18th Panzer Regiment at River Bug in 19412,3. Also issued to the 6th Panzer Regiment of the 3rd Panzer Division.
