The A-10 Thunderbolt II in Redstone Arsenal.
Redstone Arsenal is a U.S. Army post and a census-designated place (CDP) located next to the city of Huntsville in Madison County, Alabama, United States, and is included in the Huntsville-Decatur Combined Statistical Area. The primary tenant organizations are the United States Army Aviation and Missile Command and the NASA Marshall Space Flight Center.
The A-10 Thunderbolt II is a single-seat, twin-engine jet aircraft developed by Fairchild-Republic for the United States Air Force to provide close air support (CAS) of ground forces by attacking tanks, armored vehicles, and other ground targets, also providing a limited air interdiction role. It is the first U.S. Air Force aircraft designed exclusively for close air support.
The A-10's official name comes from the P-47 Thunderbolt of World War II, a fighter that was particularly effective at the CAS mission. However, the A-10 is more commonly known by its nickname "Warthog" or simply "Hog". As a secondary mission, it provides airborne forward air control, guiding other aircraft against ground targets. In the USAF inventory, the airframe is designated OA-10 when used primarily in a forward air control role.
