History

The PW-9 series was developed in the early 1920s as Boeing's entry into the US Army Air Service pursuit category. The PW-9A was a refined variant with detail improvements over the original PW-9. These aircraft served as a foundation for Boeing's subsequent pursuit designs and helped establish the company's reputation with the US military. Total production of all PW-9 variants was around 30 aircraft.

Variants

The PW-9 series comprised the PW-9, PW-9A, PW-9B, PW-9C, and PW-9D, each with progressive refinements. The related FB series served with the US Navy.
