History
Introduction date1941
Developed from Northrop A-17

The Douglas A-33 (Model 8A-5) was an American attack aircraft built in small numbers during World War II. It was an updated version of the Northrop A-17, with a more powerful engine and an increased bomb load. While the A-33 was intended initially for the export market, the entire production run was taken up by the United States Army Air Corps.

Design and development

In 1932, the Northrop Corporation had been formed as a partly owned subsidiary of Douglas and by 1937, the Northrop Model 8 became known as the Douglas 8A produced in the El Segundo Division of Douglas aircraft.

The 8A-5 was powered by a 1,200 hp (895 kW) Wright R-1820-87 engine and was the most powerful and best armed of the series, with four wing mounted 0.30 in machine guns, two 0.50 in machine guns in pods below the wing, a rear-firing flexibly mounted 0.30 in gun, and the ability carry up to 2,000 lb of bombs.

Operational history

Early in 1940, the Norwegian government ordered 36 8A-5s which not had been delivered before Norway was invaded by the Germans. Completed between October 1940 and January 1941, the aircraft were delivered to a training center in Canada that had been set up for the Norwegian government-in-exile, named "Little Norway" at Toronto Island Airport, Ontario.

After the loss of two aircraft and a reassessment of the training needs now met by the use of other aircraft, the remaining 34 Model 8A-5Ps were sold to Peru. However, 31 were repossessed by the Army Air Corps at the start of World War II. These aircraft, designated A-33, were used for training, target tug, and utility duties. [1]

The Douglas A-1 Skyraider is an American single-seat attack aircraft in service from 1946 to the early 1980s, which served during the Korean War and Vietnam War. The Skyraider had an unusually long career, remaining in frontline service well into the Jet Age ; thus becoming known by some as an "anachronism". The aircraft was nicknamed "Spad", after the French World War I fighter.

The Douglas A-26 Invader is an American twin-engined light bomber and ground attack aircraft. Built by Douglas Aircraft Company during World War II, the Invader also saw service during several major Cold War conflicts. A limited number of highly modified United States Air Force aircraft served in Southeast Asia until 1969. It was a fast aircraft capable of carrying a large bomb load. A range of guns could be fitted to produce a formidable ground-attack 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.

An attack version called the A-11 was also built, along with 2 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 Northrop N-3PB Nomad was a single-engined American floatplane of the 1940s. Northrop developed the N-3PB as an export model based on the earlier Northrop A-17 design. A total of 24 were purchased by Norway, but were not delivered until after the Fall of Norway during the Second World War. Exiled Norwegian forces used them from 1941, operating from Iceland, for convoy escort, anti-submarine patrols, and training purposes from "Little Norway" in Canada. Within two years of delivery, the design was obsolete for front-line service and the remaining N-3PBs were replaced by larger aircraft in 1943.

The Mitsubishi Ki-51 was a light bomber/dive bomber in service with the Imperial Japanese Army during World War II. It first flew in mid-1939. Initially deployed against Chinese forces, it proved to be too slow to hold up against the fighter aircraft of the other Allied powers. However, it performed a useful ground-attack role in the China-Burma-India theater, notably from airfields too rough for many other aircraft. As the war drew to a close, the Japanese began using them in kamikaze attacks. Total production was around 2,385 units.

It was also used to attack targets as far-flung as western China, India and northern Australia. The Allies designated it under the reporting names "Sally" /"Gwen".

The Vought V-141 was a prototype American single-seat fighter aircraft of the 1930s. It was a development of the unsuccessful Northrop 3-A design, but was itself a failure, being rejected by the United States Army Air Corps.
