A single engine attack aircraft able to carry more tonnage of bombs than a WWII B-17 all while operating from a aircraft carrier. Marine Squadron VMA-121 routinely struck enemy targets with bomb loads in excess of 9,000 lbs. The 3,180 Skyraiders were produced in 20 different versions and modified further into at least 7 other variants. Furthermore, Douglas created conversion kits for the AD-5 allow ing it to be modified at squadron level into a four-seat or ten seat COD aircraft, a target tug, an air ambulance, a cargo aircraft, or a aerial tanker. As an attack aircraft, it became the weapon of choice for close air support and ground attack in Korea because of its ability to loiter for hours with a variety of bombs, rockets and napalm and its ability to take hits and bring its pilot's home. It repeated these tasks in Vietnam where it also became the RESCAP aircraft of choice due to its ability to stay airborne for up to 12-hours.
