The Boeing P-12 or Boeing F4B is an American pursuit aircraft that was operated by the United States Army Air Corps, United States Marine Corps, and United States Navy. It was the chief fighter aircraft in American service during the early 1930s but also used internationally. By the late 1930s it was replaced in front-line duty by newer designs, but it was still used for training into the early 1940s. Many variants of the aircraft were developed. In the 21st century a handful of surviving air frames are on display in museums.

Developed as a private venture to replace the Boeing F2B and F3B with the United States Navy, the Boeing Model 99 first flew on 25 June 1928. The new aircraft was smaller, lighter and more agile than the ones it replaced but still used the Wasp engine of the F3B. This resulted in a higher top speed and overall better performance. As result of Navy evaluation 27 were ordered as the F4B-1; later evaluation by the United States Army Air Corps resulted in orders with the designation P-12. Boeing supplied the USAAC with 366 P-12s between 1929 and 1932. Production of all variants totaled 586 (read more).
