M4 Sherman Duplex Drive

Recreate one of the most ingenious armoured engineering solutions of World War II with the American M4 Sherman Duplex Drive. Developed to support opposed amphibious landings, this specialised Sherman combined conventional tank capabilities with equipment that allowed it to float and propel itself through water before fighting ashore.

Historical Role

The Duplex Drive Sherman was intended to provide immediate armoured support during amphibious assaults. Launched from landing craft offshore, it could travel through the water under its own power, reach the beach and then continue inland on its tracks. Once ashore, the flotation screen was lowered so the crew could operate the vehicle as a conventional medium tank.

Distinctive Appearance

The defining feature is the collapsible flotation screen surrounding the hull, supported by a framework that transformed the tank’s silhouette when raised. Marine propulsion equipment, including rear-mounted propellers, further distinguishes the vehicle from a standard Sherman. These practical yet unconventional additions earn this model its ENGINEERING badge, recognising the inventive combination of a flotation system and powered water propulsion created for amphibious landings.

Variant Differences

Developed from the M4 Sherman family, the Duplex Drive conversion retained the tank’s established armament while adding a collapsible canvas flotation screen, supporting framework and propellers driven by the vehicle’s powertrain. The bulky screen installation and associated rear equipment are the most visible modelling differences. The conversion existed to bring tanks ashore under their own power and provide fire support during the critical opening stages of a landing.

Modelling Uses

This model is ideal for World War II beach dioramas, amphibious assault scenes and engineering-themed collections. Smaller scales suit model railways and compact wargaming displays, while larger versions provide greater presence for detailed painting, weathering and collectors’ displays.

Fun Fact

The name “Duplex Drive” referred to the tank’s two methods of movement: tracks on land and propellers in the water. It did not mean that the vehicle had two drivers.

Available Scales

Available in 1:87, 1:76, 1:72, 1:48 and 1:35 scales.

Finish Options

Choose from Cleaned Resin Grey, Grey Primed - Ready for Painting, or Historical Base Colour. Very small details may vary slightly depending on the scale selected.
