The American Boeing P-26, nicknamed the "Peashooter", was the first all-metal production fighter aircraft and the first pursuit monoplane used by the United States Army Air Corps. The prototype first flew in 1932, and were used by the Air Corps as late as 1941 in the Philippines.

Design and development

The Boeing-funded project to produce the Boeing Model 248 began in September 1931, with the Army Air Corps supplying engines and instruments. The design included an open cockpit, fixed landing gear and externally braced wings, the last such design procured by the USAAC as a fighter plane. It also saw the introduction of flaps to reduce speeds for landings. The Army Air Corps contracted for three prototypes, designated XP-936, with the first flight on 20 March 1932.

The Boeing XP-936 had a landing problem. Sometimes when landing it would flip forward and because of the short nose it would roll onto its back. This injured many pilots until the unarmored back canopy was replaced with an armored headrest. An additional 25 aircraft were completed as P-26Bs, with Pratt & Whitney R-1340-33 Wasp engines, and 23 P-26Cs had minor changes to carburation and the fuel system. Both Spain (one fighter) and China (11 fighters) ordered the Model 281 export version of the P-26C in 1936.

The diminutive "Peashooter" as it became affectionately known by service pilots, was faster than previous American combat aircraft, but it was also an anachronism. Although the P-26 introduced a modern monoplane design, worldwide fighter aircraft developments soon outstripped the P-26. The Messerschmitt Bf 109 which had its maiden flight in 1935 was much more representative of contemporary monoplane fighter designs. However, the P-26 was easy to fly and remained in active service for many years until the United States entered World War II.

Deliveries to USAAC pursuit squadrons began in December 1933 with the last production aircraft in the series coming off the assembly line in 1936, designated the P-26C. Ultimately 22 squadrons flew the Peashooter, with peak service being six squadrons in 1936. P-26s were the front-line fighters of the USAAC until 1938, when Seversky P-35s and Curtiss P-36s began to replace it. 20 P-26s were lost in accidents between 1934 and the start of World War II, but only five before 1940.

USAAC units assigned the P-26 were the:

• 20th Pursuit Group (55th, 77th, and 79th PS), Barksdale Field, Louisiana;
• 1st Pursuit Group (17th, 27th, and 94th PS), Selfridge Field, Michigan; and
• 17th Pursuit Group (34th, 73rd, and 95th PS), March Field, California.

Overseas deployments

Between 1938 and 1940, P-26s were assigned overseas to supplement Seversky P-35s in two defense units based at Wheeler Field, Territory of Hawaii:

• 18th Pursuit Group (6th, 19th, 73rd, and 78th PS)
• 15th Pursuit Group (45th and 47th PS).

The 17th PG became the 17th Attack Group in 1935, and its P-26s were transferred in 1938 to the 16th Pursuit Group (24th, 29th, and 78th PS) at Albrook Field in the Panama Canal Zone. These planes were transferred in 1940 to the 37th Pursuit Group (28th, 30th, and 31st PS) which flew them until they were replaced by P-40s in May 1941. Some continued service with the 32nd Pursuit Group (51st and 53rd PS), but only nine P-26s remained operational in Central America at the start of World War II.

P-26As were also flown by the 3rd Pursuit Squadron of the 4th Composite Group, based in the Philippines. Between 1937 and 1941, 31 were sold to the fledgling Philippine Army Air Corps.

Combat service

The first Boeing P-26 to experience major combat operation was the Chinese Model 281 in what was the world's first air-interception and destruction of raiding monoplane aircraft by monoplane aircraft. On 15 August 1937, eight of the Boeing fighters from the Chinese Air Force 3rd Pursuit Group 17th Squadron based at Chuyung airfield, engaged eight out of 20 Mitsubishi G3M Japanese bombers from the Kisarazu Air Group sent to attack Nanking. The Chinese Boeing fighters helped shoot down two of the four Japanese bombers destroyed that day without suffering any losses. Subsequent engagements between the Chinese "Peashooter" pilots and pilots of the Imperial Japanese Navy flying the Mitsubishi A5M "Claudes" were the first ever aerial dogfights and kills between monoplane fighter aircraft.A single P-26 was in service during the Spanish Civil War of 1936-39, but no aerial kills were recorded with this aircraft.

By December 1941, U.S. fighter strength in the Philippines included 28 P-26s, most in the service of the Philippine Army Air Corps. Most of these were destroyed on the ground in the first Japanese attacks following Pearl Harbor, but two flown by Filipino pilots scored victories over Japanese airplanes. In 1942, in a desperate defense of their homeland, the few surviving P-26s which the Filipino 6th Fighter Squadron still had at its disposal were completely overwhelmed by Japanese Zero fighters.

Following Pearl Harbor, only nine P-26s remained airworthy in the Panama Canal Zone. In 1942-1943, the Fuerza Aerea de Guatemala acquired seven P-26s ostensibly by the US government smuggling them in as "Boeing PT-26A" trainers to get around restrictions of sales to Latin American countries.The last P-26 in service was still flying until 1957 with Guatemala's Air Force. The P-26's last combat operation was with Guatemala's Air Force during a 1954 coup.

The P-26 was the last Boeing fighter to enter service until Boeing acquired McDonnell-Douglas with production and continuing support contracts for the F/A-18E/F Super Hornet in 2002. Between those aircraft, Boeing did produce the experimental XF8B in 1944 as well as the prototype YF-22 in 1991.

Survivors

Two original P-26s are known to exist. One is in the collection of the National Air and Space Museum, while the other has been owned for many years by the Planes of Fame Museum located in Chino, California. Once flown regularly, the museum's P-26 was placed on static display in the mid 1980s to protect it. In 2004, the decision was made to again fly the P-26, and a restoration was begun to return the plane to flying condition. This was completed in spring 2006, with the aircraft having made its first appearances at the museum's May 2006 air show. A Replica P-26 is also on display at the National Museum of the United States Air Force in Dayton, Ohio. In addition, Mayocraft Inc., completed final assembly in September 2006 and has now begun taxi-testing anear-100 percent scale tribute to the Boeing P-26.
