The Boeing Model 15 was a United States open-cockpit biplane fighter aircraft of the 1920s, manufactured by the Boeing company. The Model 15 saw service with the United States Army Air Service (as the PW-9 series) and with the United States Navy as a carrier-based fighter (as the FB series).

Design and development

The design of the Model 15 was based on studies of the Fokker D.VII, 142 of which were brought back to the United States for evaluation as part of the Armistice Agreement ending World War I. Many of the features were similar. The Model 15 had a fuselage of welded steel tubing braced with piano wire, while the tapered single bay wings were fabric on a wooden frame, with spruce and mahogany wing spars and 3-ply wood ribs. Wing struts were changed from the normal wood used in Boeing designs to streamlined steel tubes. The landing gear had a straight axle. streamlined into a small 16inch wing

The original engine was a 300 hp Wright-Hispano, but when the 435 hp liquid-cooled Curtiss D-12 became available the aircraft was redesigned, moving the radiator from the nose to a "tunnel" under the engine. Along with some other minor design changes to the wings, the design was finalized on 10 January 1922.

The Army expressed interest in the new design, and agreed to provide armament, powerplants, and test the aircraft, while leaving Boeing the rights to the aircraft and design. The contract was signed on 4 April 1923 and the first prototype, designated XPW-9 for "Experimental Pursuit, Water-cooled engine", flew on 2 June 1923. The XPW-9 competed with the Curtiss Model 33 for contracts for a pursuit aircraft to replace the Thomas-Morse MB-3A in the U.S. Army Air Service.

Ultimately both models were accepted, with the Curtiss aircraft designated PW-8 and the Model 15 designated PW-9. The Air Service preferred the PW-9, which outperformed the PW-8 in all performance aspects except speed, and was built on a more rugged and easier to maintain design, ordering 113 aircraft (only 25 PW-8s were procured). A naval version was also developed, designated FB, and 42 aircraft produced.

Operational history

Deliveries of the first 25 PW-9s began on 30 October 1925. Boeing delivered a total of 113 PW-9s of all variants including prototypes to the United States Army Air Corps between 1925 and February 1931. Virtually all PW-9s served with overseas units, in Hawaii with the 5th Composite Group at Luke Field and later the 18th Pursuit Group at Wheeler Field, and in the Philippines with the 4th Composite Group at Clark Field, Luzon. PW-9s equipped the 3rd, 6th, and 19th Pursuit Squadrons between 1925 and 1931.

The FB-1, of which the Navy ordered 16 but received only 10 between 1 and 22 December 1924, was not modified for naval operations (for instance, no arresting hook), and was assigned to Marine Corps squadrons VF-1M, VF-2M, and VF-3M, being deployed to China in support of the Marine Expeditionary Force. Two additional planes, designated FB-2, were altered to operate on USS Langley (CV-1) with the addition of arresting gear and a straight-across axle for the landing gear. These went into service with VF-2 in December 1925. Generally satisfactory results led to an order for 27 FB-5s, which became the Navy's first fighters intended specifically for carrier operation. They were upgraded to 525 hp Packard 2A-1500 engines, and sported a row of hooks on the bottom of the axle, used to guide the plane via cables on the deck. The FB-5 first flew October 7, 1926 and was delivered to the Navy beginning in the following January, carried on barges in Puget Sound from Boeing's factory to the Langley anchored in Seattle's harbor. Hoisted aboard, their first official flights were from the carrier's deck.


Three prototypes built for Air Service evaluation. First aircraft scrapped at McCook Field on 21 February, 1925, second static tested in October 1928 and the third was still flying in December 1928.
