The Boeing XP-8 (Boeing Model 66) was a prototype American biplane fighter of the 1920s, notable for its unusual design incorporating the engine radiator into the lower wing. [1]
Boeing developed the prototype in 1926 as a private venture, with the goal of winning the Army Air Corps competition announced in 1925. Designated by Boeing as its Model 66, the airframe was basically a PW-9 with an experimental 600 hp Packard 2A-1500 engine. In order to streamline around the engine, the radiator was moved back so that the opening coincided with the front edge of the lower wing, resulting in an unusually narrow profile around the engine.
Army testing of the aircraft began in January 1928, and it handled well, but performance was lacking, achieving only a maximum speed of 173.2 mph. Even so, the prototype continued in Air Corps service until June 1929, after which it was scrapped. The airframe design lived on in the Navy's Boeing F2B.

The McDonnell XF-88 Voodoo was a long-range, twin-engine jet fighter aircraft with swept wings designed for the United States Air Force. Although it never entered production, its design was adapted for the subsequent supersonic F-101 Voodoo.
The Curtiss XP-46 was a 1940s United States prototype fighter aircraft. It was a development of the Curtiss-Wright Corporation in an effort to introduce the best features found in European fighter aircraft in 1939 into a fighter aircraft which could succeed the Curtiss P-40, then in production.
The Curtiss P-60 was a 1940s American single-engine single-seat, low-wing monoplane fighter aircraft developed by the Curtiss-Wright company as a successor to their P-40. It went through a lengthy series of prototype versions, eventually evolving into a design that bore little resemblance to the P-40. None of these versions reached production.
The Grumman XP-50 was a land-based development of the shipboard XF5F-1 Skyrocket fighter, entered into a United States Army Air Corps (USAAC) contest for a twin-engine heavy interceptor aircraft. The USAAC placed an order for a prototype on 25 November 1939, designating it XP-50, but it lost the competition to the Lockheed XP-49.
The Republic XP-69 was an American fighter aircraft proposed by Republic Aviation in response to a requirement by the USAAC for a high speed fighter. Manufacturers were encouraged to consider unorthodox designs; although the design was ordered as a prototype it was cancelled because of delays with the engine that was to power it.
The Curtiss P-6 Hawk is an American single-engine biplane fighter introduced into service in the late 1920s with the United States Army Air Corps and operated until the late 1930s prior to the outbreak of World War II.
The P-1 Hawk was a 1920s open-cockpit biplane fighter aircraft of the United States Army Air Corps. An earlier variant of the same aircraft had been designated PW-8 prior to 1925.
The Bell P-76 was the proposed designation for a production model derivative of the XP-39E, a single-engine American fighter aircraft prototype of World War II.
The Curtiss XP-71 was a 1941 proposal for an American advanced heavy escort fighter aircraft.
The Thomas-Morse MB-3 was an open-cockpit biplane fighter primarily manufactured by the Boeing Company for the U.S. Army Air Service in 1922. The MB-3A was the mainstay fighter for the Air Service between 1922 and 1925.
The Consolidated P-30 (PB-2) was a 1930s United States two-seat fighter aircraft. An attack version called the A-11 was also built, along with two Y1P-25 prototypes and YP-27, Y1P-28, and XP-33 proposals. The P-30 is significant for being the first fighter in United States Army Air Corps service to have retractable landing gear, an enclosed and heated cockpit for the pilot, and an exhaust-driven turbo-supercharger for altitude operation.
The Boeing XP-9 was the first monoplane fighter aircraft produced by the United States aircraft manufacturing company Boeing. It incorporated sophisticated structural refinements that were influential in later Boeing designs. The sole prototype exhibited unsatisfactory characteristics with its lack of pilot visibility directly leading to its cancellation.
The Boeing Model 15 was a United States single-seat 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 and with the United States Navy as a carrier-based fighter.
The Boeing XP-4 was a prototype United States biplane fighter of the 1920s that was grounded permanently after just 4.5 hours of flight testing.
The XP-13 Viper was a prototype biplane fighter aircraft designed by the American company Thomas-Morse Aircraft Corporation. The airplane was delivered to the United States Army in 1929, but they did not adopt it.
