The Boeing F4B could out perform all existing pursuit aircraft in service at the time. It was the last wooden U.S. biplane fighter. It served throughout the U. S. Navy during the early 1930's. The U.S. Army variant was designated the P-12

The Boeing F4B was innovative in that its fuselage frames were constructed of bolted aluminum tubing, except for the engine mounts and mid-fuselage areas. Previous Boeing aircraft employed welded steel tubing throughout the aircraft. Other differences from prior models were straight rather than tapered wings.

Boeing F4B aircraft were armed with either two .30 cal. or one .50 cal. machine guns. They were located in the top of the nose, firing through the propeller.

The biplane fighters were originally equipped with a 450 h.p. Pratt and Whitney R-1340-7 radial engine. The propeller was metal, two bladed. The pitch of the propeller could be adjusted on the ground. For increased range, a 55 gallon fuel tank was fitted between the landing gear legs. Up to 700 lbs. of bombs could be carried under the wings and fuselage of the aircraft.

Soon after the Boeing F4B entered service, Boeing introduced an aircraft designated the XP-12A. It incorporated improvements for trial based on suggestions by service pilots.

The model B first flew on May 12, 1930. It featured the ailerons tested on the experimental aircraft, revised elevators, and slightly larger wheels. The engine and struts were unchanged. Later, ring cowlings were incorporated into the design. The new airplane didn't perform as well as the original Boeing F4B due to an increase in weight.

The model D first flew on Sept. 15, 1931. The most significant change over the C model was a more powerful 525 hp. Pratt and Whitney R-1340-17 engine.

The final version, designated the model E, first flew as the company owned aircraft Model 218 on Sept. 29, 1930. It was intended as a test aircraft for improvements over the Boeing F4B. model E had a new, high-altitude rated R-1340-D engine.

A total of 586 Boeing F4B aircraft of all types were built. Some remained in service until 1941.
