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.
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 1,200hp (895kW) 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 2,000lb of bombs.
Operational history
Early in 1940, the Norwegian government ordered 36 8A-5s which had not 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]
