The Douglas Y1B-7 was a 1930s American bomber aircraft. It was the first US monoplane given the B- 'bomber' designation. The monoplane was more practical and less expensive than the biplane, and the United States Army Air Corps chose to experiment with monoplanes for this reason. At the time the XB-7 was ordered, it was being tested by Douglas Aircraft as an observational plane.
The Lublin R-VIII was a Polish bomber, reconnaissance aircraft and seaplane designed in the late 1920s by the Plage i Laśkiewicz factory in Lublin. It was the first in-house design of Plage i Laśkiewicz, and the first with the name Lublin.
The Vickers Virginia was a biplane heavy bomber of the British Royal Air Force, developed from the Vickers Vimy.
The Avro 549 Aldershot was a British single-engined heavy bomber aircraft built by Avro.
The Yokosuka B4Y was a carrier-borne torpedo bomber used by the Imperial Japanese Navy Air Service from 1936 to 1943. The B4Y replaced the Mitsubishi B2M2 and was the last biplane bomber used operationally by the Imperial Japanese Navy. The Allied reporting name was "Jean".
The Airco DH.11 Oxford was a British twin-engined biplane bomber which was designed to replace the earlier Airco DH.10 Amiens. It was designed to use the unsuccessful ABC Dragonfly engine and was abandoned after the first prototype was built.
The Avro 571 Buffalo was a prototype British carrier-based torpedo bomber biplane, designed and built by Avro in the 1920s. It was not selected for service, the Blackburn Ripon being ordered instead.
The Blackburn T.4 Cubaroo was a prototype British biplane torpedo bomber of the 1920s. Built by Blackburn Aircraft and intended to carry a large 21 in (533 mm) torpedo, the Cubaroo was one of the largest single-engined aircraft in the world at the time of its first flight.
The Curtiss Eagle was an airliner produced in small numbers in the United States shortly after World War I. The aircraft was a conventional biplane with three-bay, unstaggered wings of equal span. The fuselage was a very advanced design for its day, incorporating careful streamlining of its monocoque structure, and offering the crew as well as the passengers a fully enclosed cabin. The Eagle is sometimes named as the first American tri-motor aircraft; however Curtiss' own Model H flying boat flew with three engines for a time in 1914 before being converted back to twin-engine configuration.
The Curtiss Model R was a utility aircraft produced for the United States Army and Navy during World War I. It was a conventional, two-bay biplane with slightly staggered wings of unequal span. The aircraft was provided with two open cockpits in tandem and fixed tailskid undercarriage, but many were built for the Navy with twin floats replacing the wheels. During the course of the war, Model Rs were used for general liaison and communication duties, as well for observation, training, and as air ambulances. In practice, the Curtiss powerplants supplied with these aircraft proved insufficient and were mostly replaced with Liberty engines. The Navy's Model R-3 floatplane had extended-span, three-bay wings, and was intended for use as a torpedo bomber. Some of these were later fitted with wheeled undercarriage and transferred to the Army as bombers under the designation Model R-9.
The Huff-Daland LB-1 was an American biplane light bomber aircraft operated by the United States Army Air Service in the 1920s.
The PZL.4 was a Polish three-engine passenger aircraft for 10 passengers, built in PZL factory in 1932, which remained a prototype. It was the first Polish-designed and produced multi-engine plane.
The Gotha WD.14, WD.20, and WD.22 were a family of biplane torpedo bomber floatplanes developed in Germany during World War I.
The Nakajima B3N was a prototype Japanese carrier-based torpedo-bomber aircraft of the 1930s. A single-engined biplane with a crew of three, it was unsuccessful, only two being built.
The Mitsubishi 3MT5 was a Japanese bomber of the 1930s. It was a twin-engined biplane that was intended to operate from Japanese aircraft carriers, but proved to be unsuitable for carrier use, and the eleven aircraft built were instead used as land-based trainers.
The Thomas-Morse MB-4 was a prototype American mailplane of the 1920s. It was of unusual design, being a biplane with twin fuselages housing the crew of two and a central nacelle which carried the aircraft's twin engines in a push-pull configuration.
The Nakajima D3N was a Japanese carrier-based dive bomber of the 1930s. Three prototypes were built for the Imperial Japanese Navy, but no production followed, with the Aichi D3A being selected instead.
G Elias & Brother was and American manufacturer of cabinets and aircraft based in Buffalo, New York in the 1920s. A.G. Elias sat on the Manufacturers Aircraft Association's board of directors along with President Frank H. Russell, VP Glenn L. Martin, Charles L. Laurence, Chance M. Vought, S.S. Bradley, George P. Tidmarsh, and Donald Douglas. E.J Elias promoted the construction of a Buffalo municipal airport to aid the local fledgling airplane industry of five aviation companies constructing airplanes and airplane parts. From 1920 to 1925, Elias company's chief engineer, David Earle Dunlap (1896-1957), designed the Elias EM-2 Expeditionary planes. He designed the NBS-3 bomber fuselage and the Elias M-1 Mail plane. Dunlap's Elias TA-1 design was the first United States Army Air Corps Trainer to have a radial engine. After tests a McCook Field, the Army Air Corps selected other manufacturers over the Elias bomber and trainer. The company designed the Elias EM-1 to meet requirements for a multirole amphibian marine expeditionary aircraft. Elias delivered six production Elias EM-2 aircraft with Liberty engines to the United States Navy in 1922.
The Breda A.3 was a prototype twin-engined biplane, designed by Società Italiana Ernesto Breda, as a night bomber in 1924.
The 1929 Curtiss Model 53 Condor, also known as the Curtiss Model 53 Condor 18 or the Curtiss CO Condor, was a civil passenger version of the Model 52 Condor bomber. A twin-engined biplane, it carried 18 passengers.
