Boeing's diminutive P-26 fighter bridged the gap between stick-and-wire biplanes and modern, all-metal monoplane fighters. Boeing's P-26 was a milestone in three respects. It was the first U.S. Army Air Corps fighter to incorporate several important design features that would become standard on aircraft subsequently used in World War II. To placate conservative elements in the Air Corps, however, the P-26's designers were constrained to include several anachronistic features in the airplane that hampered its development potential. The Peashooter was also to be the last fighter aircraft mass-produced by Boeing before the company went on to bigger things, in both the figurative and the literal sense. The company that would later become Boeing Aviation was founded in 1916 by William Edward Boeing. He was a prominent Seattle businessman who found little difficulty in making a transition of his own, from the lumber business to speedboat building to seaplane construction. Considering the company's long-standing reputation for building large aircraft, it is often forgotten that Boeing was ever in the fighter business. During the 1920s, however, the Seattle-based company was in close competition with its eastern rival, Curtiss, for a dominant place in the American fighter arsenal. Boeing's first large aviation contract, secured in 1919, was for the construction of 200 Thomas-Morse MB-3 fighters for the U.S. Army Air Service. Known as the MB-3A, Boeing's version incorporated a number of improvements over the Thomas-Morse original, including redesigned tail surfaces, improved radiators and a welded steel-tube fuselage in place of the original's wooden structure. As a result of the quality of the MB-3A, Boeing went on to become one of the giants of the aviation industry while Thomas-Morse faded into obscurity. The P-26A of 1934 changed pursuit styling.Inspite of it's exposed landing gear it could still fly 230 miles an hour. Boeing's next fighter project, the Model 15, was an original design employing a steel-tube fuselage, wooden wings and a 435-hp Curtiss D-12 liquid-cooled engine. Submitted in direct competition with a design from the much larger Curtiss Company, Boeing took a big chance on the new fighter by building the prototype airframe at the company's own expense. The gamble paid off when the Army awarded Boeing a contract for 30 production versions in 1923, which they called the PW-9 (pursuit, water-cooled). The Navy also bought 14 examples under the designation FB-1 (fighter, Boeing). The Model 15 was the first in an unbroken series of production Boeing fighters that would culminate in the P-26. Boeing biplane fighter development reached its pinnacle with the introduction of the Model 83 in 1928. Constructed of bolted aluminum instead of welded steel, the Model 83 was more compact than its predecessors. Powered by a 450-hp Pratt and Whitney Wasp air-cooled radial engine, it was a great success. The Model 83 was ordered over the next five years in successively improved models, designated for the Army as the P-12 and for the Navy as the F4B. Despite the success of the Model 83, Boeing's management was convinced that the days of the biplane were numbered. Boeing began investigating the possibility of a monoplane fighter in 1928. This resulted in the appearance of three prototype monoplanes in 1930. The first two, built as a private venture, were little more than parasol-winged derivatives of the Model 83. One was demonstrated to the Army as the XP-15. The other, a similar airplane equipped with a tail hook, was delivered to the Navy as the XF5B-1. Both proved to be faster than the equivalent Boeing biplane, but both were rejected because their rate of climb and maneuverability were inferior to the Model 83. Monomail Model 200 The third monoplane fighter prototype, the XP-9, appeared later in 1930. It was a more radical design built to meet an Army specification. Powered by a 600-hp Curtiss water-cooled engine, the XP-9 was a shoulder-wing monoplane with an aluminum monocoque fuselage. The plane's top speed of 213 mph was much faster than either of the parasol-winged prototypes or the production Model 83. However, the cockpit was located just aft of the strut-braced wings, severely restricting the pilot's view. The design was also criticized for poor control characteristics. The Army preferred to stay with the P-12, which was a proven winner. The appearance of yet another Boeing monoplane prototype in 1930, the Model 200 Monomail, was of far greater significance. Designed as a high-speed mail plane, the Monomail's development was a result of Boeing's experience in the airline business during the 1920s. Boeing Air Transport, as the airline subsidiary was known, later became the basis for today's United Airlines. The Monomail was a cantilevered, low-winged monoplane with an aluminum monocoque fuselage and retractable landing gear. The plane was 41 feet long, had a span of 59 feet, and could fly 600 miles with a payload of 2,300 pounds of mail or passengers. The top speed of the sleek Monomail, a modest 158 mph, was restricted only by the relatively low power of its single 525-hp Pratt and Whitney Hornet radial engine. The Monomail was the true progenitor of the unbroken line of highly successful Boeing airliners leading up to today's Model 777. Boeing XP-936 In 1931, Boeing developed a twin-engine bomber for the Air Corps based on the design of the Monomail, called the B-9. It would be the first of a long line of illustrious Boeing bombers. With a top speed of 186 mph, the B-9 rendered Boeing's own P-12/F4B biplane fighters virtually obsolete. It was also in 1931 that Boeing's designers began work on a new monoplane fighter that the company designated the Model 248 and that was initially known to the Air Corps as the P-936. First flown on March 20, 1932, the new fighter was an all-metal, low-wing monoplane with an aluminum monocoque fuselage, somewhat reminiscent of a scaled-down Monomail. However, the similarities ended there. Like the earlier PW-9, the three P-936 prototypes were funded by Boeing, with only the engine and instruments being supplied by the Air Corps. The Boeing Company was in the business of selling aircraft at a profit, not wasting money on futuristic but unwanted prototypes. It therefore took a conservative approach in the design of its new fighter in the hope that the aircraft would prove more readily acceptable to the Army Air Corps. Aviation experts of that period were dubious about the value of a retractable landing gear. It was widely believed that any reduction in drag would be offset by the added weight of the retraction mechanism. The early retractable landing gears, which were manually operated, were also notoriously prone to malfunction. The new Boeing fighter was therefore designed with a fixed landing gear in streamlined fairings. The Air Corps was convinced that a cantilevered wing would not stand up to the stresses imposed by the violent maneuvers of a fighter. Consequently, the Model 248's wings had external wire bracing not unlike that on the monoplane fighters of World War I. Many pilots of the early 1930s also considered good visibility to be one of a fighter plane's most important characteristics. Before the advent of airborne radar, the pilot who survived was often the one who saw his opponent first. Aircraft radio was still in its infancy, thus communications between pilots were often carried out by visual signals.

The P-12F and the P-26 were both powered by the same 600-hp Pratt and Whitney Wasp air-cooled radial engine, and their performance characteristics make an interesting comparison. The top speed of the P-26 was 234 mph--20 percent faster than the P-12F. It also had a range of 375 miles, 75 miles farther than that of the biplane. Because of its lower wing loading, however, the P-12F's climb rate of 2,920 feet per minute was 24 percent greater than that of the monoplane. Also, the P-12F's service ceiling of 31,400 feet was 4,000 feet higher than that of the P-26.
The Boeing management must have realized that, even with the new flaps, the P-26's stall speed would have been unacceptable for use on a carrier deck. Unlike with its previous fighter designs, Boeing did not offer a version of the P-26 to the Navy. The Navy did not accept any monoplane fighters at all until 1939, when the Brewster F2A Buffalo entered service.
Another alteration to the design resulted from a fatal accident involving one of the P-26 prototypes. The airplane flipped over onto its back while landing, breaking the test pilot's neck. The upper wing of the biplanes had provided a measure of protection under these circumstances, but the P-26's low-wing design left the pilot vulnerable to serious injury. Hence, the pilot's headrest was raised an additional eight inches on production models and was internally reinforced like the roll bar on a racing car. The new headrest gave the P-26 a humpbacked appearance that remains one of the airplane's most distinctive features.
The Air Corps bought a total of 139 Peashooters between 1933 and 1934, including the three original prototypes. The majority were P-26As of the initial production batch, of which 111 were built. The next 25, designated P-26Bs, were to have been equipped with a fuel-injected version of the Wasp engine that promised to improve the plane's performance at higher altitudes, but only three of the new engines were initially available. The remaining 22 airframes were completed as P-26Cs, designed to accept the fuel-injected engine but equipped with the carbureted engine of the P-26A. As more fuel-injected engines became available, some of the P-26Cs were subsequently upgraded to P-26Bs.
The Peashooter was 23 feet 7 inches long, and its wing spanned 28 feet. The fighter weighed 2,271 pounds empty and just over 3,000 pounds loaded. It was armed with two synchronized machine guns in the floor of the cockpit, either two .30 calibers or one .30 and one .50 caliber. The plane also could carry up to 200 pounds of bombs in a rack under the fuselage. The Peashooter appeared at the height of the Depression, when the various branches of the military were competing for the limited funds available from the government. Many people still did not take military aviation seriously, and the Army Air Corps was anxious to show off its capabilities in the hope of gaining public support for expanding the service. As a result, the mid-1930s became arguably the most colorful period in American aviation history.
Paleontologist Stephan Jay Gould has made the case that evolution does not proceed at a steady rate, but happens in fits and starts. The P-26 provides an illustration of that theory. The Peashooter had the misfortune to be introduced into service at the beginning of one of the most explosive periods of development in the history of aviation technology. Boeing's monoplane fighter, which was regarded as advanced in 1933, appeared outmoded next to the Martin B-10 bomber, (introduced in 1934) with its enclosed cockpits, retractable landing gear and 212-mph top speed. Compared to the Seversky P-35 and Curtiss P-36 fighters that appeared in 1936, and corresponding foreign designs such as the Hawker Hurricane and Messerschmitt Bf-109, the Peashooter seemed a whole generation out of date.
The P-26, considered radical at the time of its introduction, had become obsolete within three years. The very features that Boeing had designed into the fighter to placate a then-conservative Army Air Corps staff had doomed it to rapid extinction.
The introduction of the far more advanced Seversky P-35 caused the Peashooters to be displaced from Stateside fighter units. By 1938, they were only operational with fighter squadrons at remote overseas bases in Panama, Hawaii and the Philippines. The rest were relegated to the advanced training role, preparing pilots to fly the next generation of fighters.
While the production lines were turning out P-26s for the Air Corps, Boeing contracted to supply a batch of similar fighters to the Nationalist Chinese government. A total of 10 Peashooters, designated Model 281 by Boeing and Model 248 by the Chinese, were built for the Chinese in 1934. The company did not deliver the airplanes until 1936, however, because of funding problems.
The Boeings were delivered to the 17th Squadron, commanded by Wong Pan-Yang, a Sino-American volunteer from Seattle, in time to be used against Japanese aircraft over Nanking in 1937. On August 15, eight of them attacked a flight of six Mitsubishi G3M bombers and shot down all six without loss. Wong Pan-Yang in Boeing No. 1701 downed one and shared in the destruction of a second, while Los Angelesborn Wong Sun-Shui in plane No. 1703 accounted for a third. The rig-ors of combat and primitive operating conditions took a heavy toll on the Boeing fighters, though, and by the end of 1937 none of them remained operational. The 17th was re-equipped with Gloster Gladiator biplanes, in which Wong Pan-Yang would bring his total score to five. Wong Sun-Shui was credited with 812 victories before being mortally wounded in action on March 14, 1941.

P-26 of 94th Pursuit Squadron, Selfridge Field, Michigan, 1937. The P-26A was the first all-metal monoplane pursuit plane produced for the U.S. Army Air Corps, affectionately called the "Peashooter" by its pilots. The Consolidated Y1P-25 was the first all-metal pursuit plane tested, but the production version, P-30, was purchased after the initial P-26 orders. The P-26 was also the last Army Air Corps pursuit aircraft accepted with an open cockpit, a fixed undercarriage, and an externally braced wing. Significantly faster in level flight than previous fighters, the P-26A's relatively high landing speed caused the introduction of landing flaps to reduce this speed. Y1P-26 Boeing initially designed the P-26 in 1931, designating it first as Model 248 and in December 1931 as the XP-936. The company provided three test airframes, which remained Boeing property, with the frugal Air Corps providing the engines, instruments, and other equipment. The first flight occurred on March 20, 1932. The Army Air Corps purchased the three prototypes and designated tham as Y1P-26s. The Air Corps purchased a total of 111 of the production version, designating them as P-26A, and 25 of later -B and -C models. |

Good morning Snippy and everyone at the Foxhole.
Wow, Peashooter Bump for the Freeper Foxhole.
I have some Peashooter pics, will have to get daughter to install the FTP program before she goes back to school. Will post pics later, much later.
Iris7 you mentioned the Sydney Camm's Hurricane, it was the first aircraft to have an 8 gun battery in the wings, .303 caliber.
Off to work and it is a balmy 8 degrees here in KC.

God . . . has blessed us with every spiritual blessing in the heavenly places in Christ. Ephesians 1:3
Bible In One Year: Genesis 16-19
Tennis superstar Arthur Ashe died of AIDS, which he contracted from a blood transfusion during heart surgery. More than a great athlete, Ashe was a gentleman who inspired and encouraged many with his exemplary behavior on and off the court.
Ashe could have become embittered and self-pitying in the face of his disease, but he maintained a grateful attitude. He explained, "If I asked, 'Why me?' about my troubles, I would have to ask, 'Why me?' about my blessings. Why my winning Wimbledon? Why my marrying a beautiful, gifted woman and having a wonderful child?"
Ashe's attitude rebukes those of us who often grumble, "Why me? Why is God allowing this to happen?" Even if we're suffering acutely, we must not forget the mercies God pours into our livessuch things as food, shelter, and friendsblessings that many are deprived of.
And what about spiritual blessings? We can hold the very Word of God in our hands and read it. We have the knowledge of His saving grace, the comfort of His Spirit, and the joyful assurance of life everlasting with Jesus.
Think about God's blessings and ask, "Why me?" Then your grumbling will give way to praise. Vernon Grounds
The Lancair 235 I built is approximately the same size, but weighs less than 1/3 the weight of a P-26. When completed, it will fly almost as fast (200 MPH) on 140HP rather than 600.
Good morning Neil.
Good Morning Feather!
Good morning Aeronaut.
Thanks for the coffee. I'm up early and need it.
