Curtiss H-16

The Curtiss H-16 was a large twin-engine biplane flying boat, the final and most refined of Curtiss's 'America' patrol flying boats developed during World War I. Built by the Curtiss Aeroplane and Motor Company, with many produced under license by the U.S. Naval Aircraft Factory, it entered service in 1918 and was flown by both the U.S. Navy and Britain's Royal Air Force. Powered by two Liberty engines and armed with multiple machine guns and depth bombs, the H-16 conducted long-range maritime reconnaissance and anti-submarine patrols, notably over the North Sea against German U-boats.

Roughly 334 were built, 184 by Curtiss and 150 by the Naval Aircraft Factory. It remained in U.S. Navy service into the 1920s and was a direct ancestor of the closely related Felixstowe F.5L. The existing label misspells 'Curtiss'; wingspan is more reliably about 95-96 ft.
