Developed to a World War II specification for a carrier-base dive-bomber and torpedo-carrier-- the first single-seater in this category -- the Skyraider was too late for service in that conflict, but proved to be one of the most versatile air weapons available to the US forces in both the Korean War and the Vietnam War.  Although production ended in 1957, 12 years after the line was first established, serious proposals were made as late as 1966 for re-establishment of production in order to meet Vietnam needs.  By that time the Skyraider had become widely known as the Spad, a name which reflected the affection in which it was held by its pilots who likened its reliability and versatility to the famed World War I fighter.
