The Douglas A-20/DB-7 Havoc was a family of American attack, light bomber and night fighter aircraft of World War II, that served with several Allied air forces, principally those of the Soviet Union, United Kingdom, and United States. The DB-7 was also used by the air forces of Australia, South Africa, France, and the Netherlands during the war, and Brazil afterwards. The bomber aircraft was known as Boston among British and Commonwealth air forces, while the Royal Air Force night fighter variants were given the service name Havoc. The United States Army Air Forces assigned the DB-7 the designation "A-20" and gave it the popular name "Havoc".
In March 1937, a design team headed by Donald Douglas, Jack Northrop and Ed Heinemann produced a proposal for a light bomber powered by a pair of 450 hp (336 kW) Pratt & Whitney R-985 Wasp Junior engines mounted on a high-mounted wing. It was estimated it could have carried a 1,000 lb (454 kg) bomb load at 250 mph (400 km/h). Reports of aircraft performance from the Spanish Civil War indicated that this design would be seriously underpowered, and it was subsequently cancelled.
