The Naval aircraft factory at the Navy Yard, Philadelphia, was organized during the stress of the World War when naval officers were not available to recruit the organization and the work of airplane manufacture was a new departure for the Navy. The engineers and executives for the factory were procured almost entirely from civil life and the organization was so drawn as best to handle the factory’s peculiar mission. Naval precedent and tradition had little place in the structure of the organization and the selection of personnel. The present structure of the organization, although in some particulars similar to that of the standard Navy industrial organization, presents certain salient and unusual features which may be of interest to students of naval industrial management. The following organization chart shows the Naval aircraft factory lines of authority and the relations existing among the different offices and sub-divisions of the main departments. Special attention is invited to the position of inside superintendent, to which a member of the supply corps was assigned May 15, 1923.
