WEFT is AircraftIQ's four-point recognition method — how it works.

Spot it by:

Essentially identical to the PW-9A in outline; slight differences in engine cowling and detail fittings; the inline engine and sesquiplane layout identify the type within the Boeing pursuit family.

History

Ordered by the US Army Air Corps in 1927, the PW-9C represented the most refined version of the PW-9 design before the transition to radial engines in pursuit aviation. It served alongside earlier PW-9 variants at US Army pursuit squadrons. The experience gained with the PW-9 series fed directly into Boeing's P-12 design.

Variants

Part of the PW-9 family; the next development was the P-12 series with a Pratt & Whitney Wasp radial engine.

Where you'll see it

Operated by the US Army Air Corps in the late 1920s; quickly replaced by radial-engine types.
