The Douglas A-26 "Invader" (renamed B-26 between 1948-1965 ) is an American-made multi-functional twin-engine light bomber/attack aircraft. Built by Douglas in response to a bid by the US Army Air Force. It served during the latter half of World War II and into the early part of the Cold War. By 1969, only a limited number of highly modified aircraft (renamed A-26) were still in service.
