The Skyraider was originally designed in the 1940s by Ed Heinemann of the Douglas Aircraft Company, as a simpler alternative to the XBTD-1. At the time of the first prototype\'s flight on 18 March 1945, it was the largest production single-seater aircraft. The low-wing monoplane design started with a Wright R-3350 radial engine, later upgraded multiple times. Its distinctive feature was the presence of seven hardpoints on each wing, enabling it to carry a tremendous amount of ordnance for its size.
