The Douglas Boston aircraft (DB7) was a highly effective light bomber/light attack aircraft. It was powered by a pair of Wright Cyclone 2600 supercharged engines developing 1600 horsepower. These gave the Boston an impressive top speed of 260 knots.
The Douglas DB-7 served primarily with Soviet, US and British air forces.
The DB-7 was also used by Australian, South African, French and Dutch services during the War, and Brazil afterwards. The aircraft was known as the "Boston" among Commonwealth air forces, while the night fighter variants were known as the "Havoc". The USAAF assigned the DB-7 the designation "A-20" and gave it the popular name "Havoc," adopted from the RAF moniker.
