Lockheed AC-130J Ghostrider

The Lockheed AC-130J Ghostrider is a heavily armed, long-range ground-attack aircraft designed for close air support, air interdiction, and armed reconnaissance missions.

The Lockheed AC-130J Ghostrider is a heavily armed, long-range ground-attack aircraft developed by Lockheed Martin for the U.S. Air Force Special Operations Command (AFSOC). Derived from the C-130J Super Hercules airframe, it features advanced avionics, precision strike capabilities, and a variety of integrated weapon systems. The aircraft is powered by four Rolls-Royce AE 2100D3 turboprop engines, each producing 4,637 shaft horsepower, enabling a maximum speed of 416 mph (669 km/h) and a range of 3,000 miles (4,828 km) without refueling. Its armament includes a 30mm GAU-23/A cannon, a 105mm M102 howitzer, and the capability to launch precision-guided munitions such as the AGM-176 Griffin missile and GBU-39 Small Diameter Bombs. The AC-130J is equipped with advanced sensors, navigation, and fire control systems to support close air support, air interdiction, and armed reconnaissance missions.

History of the development of the Lockheed AC-130J Ghostrider

In the early 2010s, the U.S. Air Force identified the need to modernize its fleet of AC-130 gunships to address emerging threats and operational requirements. Existing models, such as the AC-130U Spooky and AC-130W Stinger II, were aging and faced limitations in payload capacity, range, and survivability against advanced air defenses. To maintain air superiority and provide effective support to ground forces, a more capable platform was necessary.

In 2011, the Air Force Special Operations Command (AFSOC) initiated the AC-130J Ghostrider program, selecting the C-130J Super Hercules as the base airframe due to its enhanced performance and reliability. Lockheed Martin was tasked with integrating advanced weapon systems, sensors, and avionics to create a versatile gunship capable of executing a wide range of missions.

The first AC-130J prototype conducted its maiden flight on January 31, 2014. Following extensive testing and evaluation, the aircraft achieved initial operational capability in 2017. The AC-130J was designed to replace older models, offering improved firepower, precision engagement, and survivability.

The AC-130J does not have a specific NATO reporting name.
