Boeing P-26
Maa	Yhdysvallat
Tyyppi	Takaa-ajo-ilma-alukset
Ensimmäinen lento	20. maaliskuuta 1932
Rakennettu	151

Nniiden Boeing P-26 "Peashooter" oli ensimmäinen amerikkalainen kokonaan metallinen hävittäjälentokone ja ensimmäinen takaa-ajava yksitaso, joka tuli laivueen palvelukseen Yhdysvaltain armeijan ilmavoimien kanssa. Boeingin suunnittelema ja rakentama prototyyppi lensi ensimmäisen kerran vuonna 1932, ja tyyppi oli edelleen käytössä Yhdysvaltain armeijan ilmavoimissa vielä vuonna 1941 Filippiineillä. Säilyneitä Peashootereita on vain kaksi, mutta näyttelyssä on kolme jäljennöstä ja kaksi muuta rakenteilla.

The End of the Biplane Era

Nniiden Boeing P-26, affectionately known as the “Peashooter” due to its blast tube for the guns, was a revolutionary aircraft for the U.S. Army Air Corps. Entering service in 1933, it was a “transitional” fighter: it ditched the traditional double wings for a modern, low-wing monoplane design and featured an all-metal semi-monocoque fuselage. However, it still clung to the past with its open cockpit, fixed landing gear, and external wire bracing. Though it was obsolete by the time WWII began, it was the fastest fighter in the world upon its debut and paved the way for the legendary fighters that followed.

Design Engineering: Old World Meets New

External Wire Bracing: Unlike later “cantilever” monoplanes (like the Spitfire) where the wing’s strength was internal, the P-26 relied on external wires attached to the fuselage and landing gear for support. This allowed for a thinner, faster wing but created significant drag. [Image diagram of the Boeing P-26 wing bracing and rigging system]
The “Tuna Can” Cowling: The P-26 used a narrow Townend ring or NACA cowling around its radial engine. This was a cutting-edge aerodynamic feature at the time, designed to reduce drag while still allowing the air-cooled engine to breathe.
Wheel Spats (Fairings): To eke out every bit of speed, the fixed landing gear was enclosed in large, streamlined fairings. While aerodynamic, these were prone to clogging with mud on unpaved airfields. [Image detail of the P-26 landing gear fairings and fixed struts]
Flap Integration: Due to its high landing speed (for the time), the P-26 was eventually fitted with wing flaps to help pilots touch down safely on shorter runways—a relatively new concept for American pursuit pilots in the early 30s.

Combat History and the Pacific Sunset

First Blood in China: The P-26 saw its first real combat not with the U.S., but with the Chinese Nationalist Air Force. Flying exported “Model 281” variants, Chinese pilots successfully intercepted Japanese Mitsubishi G3M bombers in 1937, scoring the first monoplane fighter victories.
Defense of the Philippines: When Japan attacked in December 1941, the Philippine Army Air Corps was still flying the P-26. Against all odds, Captain Jesus Villamor and his squadron used the aging Peashooters to knock down modern Japanese A6M Zeros, proving that pilot skill could occasionally overcome technological gaps.
The Headrest Safety: The P-26 featured a very high, prominent headrest. This was designed to protect the pilot in the event of a “nose-over” landing, a common accident given the plane’s light weight and high center of gravity. [Image detail of the P-26 cockpit and large protective headrest fairing]
Guatemalan Service: Long after the U.S. retired them, the P-26 lived on in Central America. Guatemala used the Peashooter as its primary fighter until 1954, making it one of the longest-serving frontline fighters of the 1930s era.
