Also going by the names Dauntless II, AD, A-1 Able Dog, and Spad, the Douglas Skyraider saw almost 30 years of service. The Skyraider's development started in June 1944. Not completed in time for WWII, its first combat came with the outbreak of the Korean War in June 1950. The first production version to roll out of the Douglas factory was designated the AD-1. Twelve years and seven versions later, over 3200 Skyraiders had been produced.
