The Douglas A-20C was originally produced for export to Britain and the Soviet Union under lend-lease, but a large number were retained in the United States after Pearl Harbor. The A-20C was very similar to the DB-7B/ Boston III, with the same straight edge to the glass nose, self sealing fuel tanks and better armour than the A-20B. The A-20C was powered by 1,600hp Wright R-2600-23 engines, and the main change from the Boston III was the use of more efficient individual exhaust stacks in place of the collector ring used on the British aircraft.
A total of 948 A-20Cs were built – 808 by Douglas and 140 by Boeing at Seattle, of which only 200 reached the RAF, where they were known as the Boston IIIA. The British aircraft were armed with 0.303in guns, while the American A-20Cs used 0.30in guns. Most of the aircraft retained by the USAAF were used in training units, preparing for the deployment of the A-20G, the main production version of the aircraft.
