A floating tank? Yep! DD “Flotation Screens” for amphibious tanks were first developed by the British in 1941 and soon adapted for Valentines. This film shows a U.S. A4 Sherman version as it was deployed on D-Day, June 6th 1944. “DD’ stands for ”Duplex Drive” meaning both propeller and track drive capable. DD Tanks could swim at up to 4 knots. This fascinating in depth report shows in detail how the flotation screens and twin propellers were deployed and how the tank operated in water. Very detailed. A gearheads delight!
