The Douglas O-43 was a monoplane observation aircraft used by the United States Army Air Corps.
Five Y1O-31A service-test aircraft were ordered in 1931, and delivered to the USAAC in early 1933 designated Y1O-43. They differed from the final configuration of the O-31A, with a wire-braced parasol wing, and a new fin and rudder. An order for 23 O-43A aircraft was completed during 1934, with a deepened fuselage, which eliminated the need for the ventral bulge under the observer's position. Powered by a single 675 hp Curtiss V-1570-59 inline engine, it also had taller vertical surfaces with an inset rudder similar to the O-31A. The canopy was enlarged, and fully enclosed both cockpits. The O-43 and O-43A served with the USSAC observation squadrons for several years before being assigned to National Guard units, [2] such as the 111th Observation Squadron Brownwood Airfield Texas, 15th Observation Squadron Fort Sill Oklahoma, and 3rd Observation Squadron Langley Field Virginia.
The 24th airframe of the O-43A contract was completed as the XO-46 prototype.

The Curtiss Falcon was a family of military biplane aircraft built by the American aircraft manufacturer Curtiss Aeroplane and Motor Company during the 1920s. Most saw service as part of the United States Army Air Corps as observation aircraft with the designations O-1 and O-11, or as the attack aircraft designated the A-3 Falcon.
The Curtiss A-8 was a low-wing monoplane ground-attack aircraft built by the United States company Curtiss Aeroplane and Motor Company, designed in response to a 1929 United States Army Air Corps requirement for an attack aircraft to replace the A-3 Falcon. The Model 59 "Shrike" was designated XA-8.
The Fokker XA-7 was a prototype attack aircraft ordered in December 1929, and first flown in January 1931 by Fokker and then General Aviation Corporation after it bought Fokker-America in 1930, and entered in a competition held by the United States Army. However, the Curtiss A-8 won the competition, and A-7 development was not continued.
The Douglas XTB2D Skypirate was a torpedo bomber intended for service with the United States Navy's Midway- and Essex-class aircraft carriers; it was too large for earlier decks. Two prototypes were completed, but the dedicated torpedo bomber was becoming an outdated concept, and with the end of World War II, the type was deemed unnecessary and cancelled.
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 Fokker XB-8 was a bomber built for the United States Army Air Corps in the 1930s, derived from the high-speed Fokker O-27 observation aircraft.
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 Douglas O-38 was an observation airplane used by the United States Army Air Corps.
The Douglas O-46 was an observation aircraft used by the United States Army Air Corps and the Philippine Army Air Corps.
The North American O-47 is an American observation fixed-wing aircraft monoplane designed in the mid-1930s and used by the United States Army Air Corps during the Second World War. It has a low-wing configuration, retractable landing gear, and a three-blade propeller.
The Boeing YB-9 was the first all-metal monoplane bomber aircraft designed for the United States Army Air Corps. The YB-9 was an enlarged alteration of Boeing's Model 200 Monomail commercial transport.
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 Naval Aircraft Factory TS-1 was an early biplane fighter aircraft of the United States Navy, serving from 1922 to 1929.
The Douglas O-31 was the Douglas Aircraft Company's first monoplane observation straight-wing aircraft used by the United States Army Air Corps.
The Curtiss YP-20 was an American biplane fighter project developed by Curtiss for the United States Army Air Service.
The Curtiss XP-10 was an American experimental biplane fighter developed by Curtiss and tested by the United States Army Air Corps, but rejected due to disappointing performance and major problems with the cooling system.
The Curtiss XP-22 Hawk was a 1930s American experimental biplane fighter built by Curtiss for evaluation by the United States Army Air Service.
The Douglas XO2D-1 was a prototype American observation floatplane of the 1930s. It was a single engined biplane intended to be launched by aircraft catapult from ships of the United States Navy, but only one was built, the production contract going to Curtiss for the SOC Seagull.
The Curtiss CT-1 model 24, a twin engine torpedo bomber mounted on floats, was first flown in 1921.
The Aerial Service Mercury Senior, Aerial Mercury Senior or just Mercury Senior was a US biplane mailplane designed to operate at night between New York City and Chicago. A different, smaller, lower wing improved its performance for daytime flights. One was built and used by the United States Post Office Department.
