The Douglas A-20 Havoc is an American attack/light bomber/night fighter aircraft of World War II.

On September 20, 1944 the last Douglas A-20K Havoc was produced by Douglas, with 7098 having been built by Douglas and 380 under license by Boeing. The Havoc was quickly replaced in USAAF service by the Douglas A-26, the RAAF replaced them with Bristol Beaufighters, and the RAF with the de Havilland Mosquito. One of the last substantial users was the Força Aérea Brasileira (Brazilian Air Force) who continued using the A-20 until the late 1950s.

So quickly was the A-20 phased out of service and scrapped that, by the early 1960s, the aircraft was on the verge of extinction with only six complete airframes known in existence. Currently, due to numerous expeditions into the jungles of New Guinea, as well as Russian crash sites, additional restorable airframes are being discovered and the number of intact aircraft growing.
