In 1919 he was promoted to Admiral and commanded the Asiatic Fleet. While serving at the Naval Ordnance Proving Ground, Admiral Gleaves made outstanding contributions in the field of gunnery and torpedoes. While carrying out some tests on torpedo steering devices he changed these weapons from instruments of luck into instruments of precision. The gear which he tested in Cushing provided the imprints which made the torpedo the "terrible weapon" of World War I.
