A total of 560 N-9s were manufactured for the Navy during the First World War. Most of them were the Hispano-Suiza-powered N-9H model. Of these, only 100 were built by Curtiss. The majority were produced under license by the Burgess Company of Marblehead, Massachusetts. An additional 50 were assembled after the war by the Navy at the Pensacola Naval Air Station from spare components and engines.
