Douglas A-1 Skyraider From Wikipedia, the free encyclopedia The Douglas A-1 (formerly AD) Skyraider was an American single-seat attack aircraft that saw service between the 1950s and early 1970s. It became a piston-powered, propeller-driven anachronism in the jet age, and was nicknamed "Spad", after a French World War 1 fighter.[1] The Skyraider had a remarkably long and successful career and inspired a straight-winged, slow-flying, jet-powered successor, the A-10 Thunderbolt II (Warthog). It was operated by the United States Navy (USN), the U.S. Marine Corps (USMC) and the United States Air Force (USAF), and also saw service with the British Royal Navy, the French Air Force, the Air Force of the Republic of Vietnam (VNAF), and others. Design and development The piston-engined AD Skyraider was designed during World War II to meet requirements for a carrier-based, single-seat, long-range, high performance dive/torpedo bomber, and was a follow-on to earlier dive bombers and torpedo bombers used by the Navy such as the Helldiver and Avenger. Designed by Ed Heinemann of the Douglas Aircraft Company, prototypes were ordered on 6 July 1944 as the XBT2D-1. The XBT2D-1 made its first flight on 18 March 1945 and in April 1945, the USN began evaluation of the aircraft at the Naval Air Test Center (NATC).[2] In December 1946, after a designation change to AD-1, delivery of the first production aircraft to a fleet squadron was made to VA-19A.[3] The AD-1 was built at Douglas' El Segundo plant in Southern California. In his memoir The Lonely Sky, test pilot Bill Bridgeman describes the routine yet sometimes hazardous work of certifying AD-1s fresh off the assembly line (quoting a production rate of two aircraft per day) for delivery to the U.S. Navy in 1949 and 1950.[4] The low-wing monoplane design started with a Wright R-3350 radial engine, later upgraded several times. Its distinctive feature was large straight wings with seven hard points apiece. These gave the aircraft excellent low-speed maneuverability, and enabled it to carry a tremendous amount of ordnance over a considerable combat radius and loiter time for its size, comparable to much heavier subsonic or supersonic jets. The aircraft was optimized for the ground-attack mission and was armored against ground fire in key locations. This was unlike faster fighters adapted to carry bombs such as the F4U Corsair or P-51 Mustang, which would be retired by U.S. forces long before the 1960s. Navy AD series were initially painted in Midnight blue, but during the 1950s following the Korean War, the color scheme was changed to gray and white. Initially using the gray and white Navy pattern, by 1967 the USAF began to paint its Skyraiders in a camouflaged pattern using two shades of green, and one of tan. Used by the USN over Korea and Vietnam, the A-1 was a primary close air support aircraft for the USAF and VNAF during the Vietnam War. The A-1 was famous for being able to take hits and keep flying. Battle damage images from the Korean and Vietnam wars speak for themselves. There was added armor plating around the cockpit area for added pilot protection. It was replaced in the early 1970s by the A-4 Skyhawk as the Navy's primary light attack plane. The Skyraider went through seven versions, starting with the AD-1, then AD-2 and AD-3 with various minor improvements, then the AD-4 with a more powerful R-3350-26WA engine. The AD-5 was significantly widened, allowing two crew to sit side-by-side (this was not the first multiple-crew variant, the AD-1Q being a two-seater and the AD-3N a three-seater); it also came in a four-seat night-attack version, the AD-5N. The AD-6 was an improved AD-4B with improved low-level bombing equipment, and the final production version AD-7 was upgraded to a R-3350-26WB engine. In addition to serving during Korea and Vietnam as an attack aircraft, the Skyraider was modified into a carrier-based airborne early warning aircraft, replacing the Grumman TBM-3W Av...
