The Lockheed AC-130 gunship is a heavily armed, long-endurance, ground-attack variant of the C-130 Hercules transport, fixed-wing aircraft. It carries a wide array of ground-attack weapons that are integrated with sensors, navigation, and fire-control systems. Since its large profile and low operating altitudes around 7,000 feet make it an easy target, its close air support missions are usually flown at night.
