The Douglas A-26 Invader was one of the most versatile aircraft ever built. First flown in 1942, it served as a fast light bomber and attack aircraft in World War II, then went on to see heavy use in Korea and even Vietnam. With its speed, heavy armament and ability to carry bombs, rockets and guns, it proved so adaptable that it stayed in front-line service for over three decades.
