The Sherman DD (duplex drive) was devised as an amphibious tank that didn't need to be brought to shore in a landing craft, reducing the risk of vital landing ships becoming easy targets during the initial phase of the landing. The swimming tanks could arrive at the beachhead before or with the first infantry wave offering essential fire support against the defender's positions.
