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 Lockheed-Detroit YP-24 was a 1930s prototype two-seat fighter aircraft. An attack version called the A-9 was also proposed. The YP-24 is most remarkable for being the first fighter aircraft to bear the Lockheed name.
The Douglas Y1B-7 was a 1930s United States 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 1920s, derived from the high-speed Fokker O-27 observation aircraft.
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 Berliner-Joyce OJ was an American biplane observation floatplane developed by the Berliner-Joyce Aircraft for the United States Navy during the early 1930s.
The Vought O5U was a 1930s prototype American observation floatplane to meet a United States Navy requirement for a catapult launched scouting aircraft. The contract was won by Curtiss who went on to produce the SOC Seagull; only one O5U was built.
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 Cessna C-106 Loadmaster was a 1940s American twin-engined transport monoplane. Built of plywood it did not enter production due to a wartime shortage of material.
The Stearman XBT-17 was a prototype 1940s American two-seat low-wing monoplane primary trainer designed and built by Stearman Aircraft. It was evaluated by the United States Army Air Force in 1942 as the XBT-17.
The Curtiss O-40 Raven was an American observation aircraft of the 1930s which was built and used in small numbers. A single example of the YO-40, a single-engined Sesquiplane with a retractable undercarriage was built, followed by four examples of a modified monoplane version, the O-40B, which remained in use until 1939.
The Fleetwings PQ-12 , company designation Fleetwings Model 36, was a 1940s American manned aerial-target designed and built by Fleetwings for the United States Army Air Corps.
