When World War I began the United States also had what it referred to as the "Ehrhardt high-explosive shrapnel" in its inventory. It appears to be similar to the German design, with bullets embedded in TNT rather than resin, together with a quantity of explosive in the shell nose. Douglas Hamilton mentions this shell type in passing, as "not as common as other types" in his comprehensive treatises on manufacturing shrapnel and high explosive shells of 1915 and 1916, but gives no manufacturing details. Nor does Ethan Viall in 1917. Hence the US appears to have ceased its manufacture early in the war, presumably based on the experience of other combatants.
