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 "Shrike" nickname was not officially adopted).

Development

The XA-8 won a competition against the General Aviation/Fokker XA-7, after which 13 service test aircraft were ordered (five as YA-8s and eight as Y1A-8s). After the completion of testing, 11 of these aircraft were redesignated A-8.

The A-8 was the first Curtiss machine of all-metal low-wing monoplane configuration with advanced features such as automatic leading edge slats and trailing-edge flaps. [2]

Four forward-firing .30 in (7.62 mm) machine guns were mounted in the wheel fairings, and an additional weapon of the same calibre was fitted in the observer's cockpit for rear defense. The standard bomb load was four 100 lb (45 kg) bombs. [3]

One YA-8 was fitted with a radial engine and designated YA-10, while another was used for testing of the Curtiss V-1570 Conqueror engine as the Y1A-8A. This aircraft was redesignated A-8 upon the completion of testing.

46 aircraft were ordered as A-8Bs, however the order was changed to the Model 60 A-12s before production began.

Operational history

The A-8 created a sensation in US aviation circles when it went into service with the 3rd Attack Group at Fort Crockett, Texas in April 1932. All other standard aircraft were of biplane configuration, and the first monoplane fighter (the Boeing P-26A) did not become operational until eight months later. [2]

Curtiss A-12 Shrike American attack aircraft

The Curtiss A-12 Shrike was the United States Army Air Corps' second monoplane ground-attack aircraft, and its main attack aircraft through most of the 1930s. It was based on the A-8, but had a radial engine instead of the A-8's inline, water-cooled engine, as well as other changes.

Fokker XA-7 American attack aircraft prototype

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.

Curtiss B-2 Condor 1929 bomber aircraft family by Curtiss

The Curtiss B-2 Condor was a 1920s United States bomber aircraft. It was a descendant of the Martin NBS-1, which was built by the Curtiss Aeroplane and Motor Company for the Glenn L. Martin Company. There were a few differences, such as stronger materials and different engines, but they were relatively minor.

Douglas Y1B-7 American bomber/observation aircraft

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 Vultee V-11 and V-12 were American stressed-skin monocoque monoplane attack aircraft of the 1930s. Developed from the Vultee V-1 single-engined airliner, the V-11 and V-12 were purchased by several nations for their armed forces, including China, who used them in combat against Japanese forces in the Second Sino-Japanese War. The United States Army Air Corps purchased seven V-11s as the YA-19 in the years before World War II, testing them to gather data to compare against twin engine light attack 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.
