The Naval Aircraft Factory PN series were biplane flying boats designed for open-ocean patrol duties with the US Navy during the 1920s. They represented the USN's standard patrol flying boat before monoplane designs took over.

History

Developed from Felixstowe F-5L technology, the PN-7 through PN-12 series progressively refined the patrol flying boat design through the late 1920s. Various engine and airframe combinations were tested across the series. The Consolidated P2Y and Martin PM eventually supplanted the type in the early 1930s.

Variants

PN-7 through PN-12, each with different engines — Packard, Wright Cyclone, and Pratt & Whitney variants were all trialled across the series.

Where you'll see it

Operated by the US Navy on patrol duties from east and west coast naval air stations through the late 1920s into the early 1930s.
