The Douglas A-20 Havoc (company designation DB-7) is a United States attack, light bomber, intruder, and reconnaissance aircraft of World War II.
It served with several Allied air forces, principally the United States Army Air Forces (USAAF), the Soviet Air Forces (VVS), Soviet Naval Aviation (AVMF), and the Royal Air Force (RAF) of the United Kingdom. Soviet units received more than one in three (2,908 aircraft) of the DB-7s ultimately built.
It was also used by the air forces of Australia, South Africa, France, and the Netherlands during the war, and by Brazil afterwards.
In British Commonwealth air forces, bomber/attack variants of the DB-7 were usually known by the service name Boston, while night fighter and intruder variants were usually known as Havoc. An exception to this was the Royal Australian Air Force, which referred to all variants of the DB-7 by the name Boston. The USAAF referred to night fighter variants as P-70.
