Following the war, the Yard continued to be the scene of technological advances. In 1886, the Yard was designated the manufacturing center for all ordnance in the Navy. Commander Theodore F. Jewell was Superintendent of the Naval Gun Factory from January 1893 to February 1896. Ordnance production continued as the Yard manufactured armament for the Great White Fleet and the World War I navy. The naval railway guns used in France during World War I were manufactured at the Yard.
