This report summarizes the investigation conducted at the Watertown Arsenal during the period 1940-1945 in connection with the development and manufacture of helmets for the American army. After the standardization of the M1 helmet numerous production problems arose that required extensive laboratory research and experimentation for their solutions. A Helmet Industry Integration Committee was organized to focus the attention of all interested Ordnance and industry personnel upon the solution of specific problems. The Watertown Arsenal Laboratory was responsible for the development of a specification to control the quality of the Hadfield manganese steel purchased for the helmet application and aided in the development of the edge annealing process which was successfully applied to stress relieve helmets after the deep drawing operation. Metallurgical and ballistic programs associated with the development of a superior helmet and with the investigation of helmets employed by the armies of foreign nations are also summarized.
