The United States maintains a relatively small but exceptionally capable fleet of AC-130 gunships, with the exact number varying based on operational needs, retirement schedules, and modernization efforts. These heavily armed, modified C-130 transport aircraft serve as low-altitude, long-endurance aerial artillery platforms, providing critical close air support and precision firepower for ground forces. Understanding the current inventory requires looking beyond a simple static number to consider the active-duty fleet, aircraft currently in depot maintenance, and those in long-term storage.
Current Active Inventory and Operational Status
As of the most recent public assessments and congressional defense reports, the active-duty AC-130 fleet stands at approximately 28 to 30 aircraft. This figure represents the core operational force ready for deployment across the globe, distributed among the Air Force's gunship squadrons. The fleet is divided between the AC-130J Ghostrider variant, which forms the backbone of the current inventory, and the newer AC-130W Stinger II, with the older AC-130H models having been fully phased out of active service. The number is dynamic, as aircraft rotate through scheduled maintenance, upgrades, and temporary storage during drawdowns or surges in operational tempo.
AC-130J Ghostrider and AC-130W Stinger II
The AC-130J Ghostrider, manufactured by Lockheed Martin and based on the Lockheed Martin C-130J Super Hercules airframe, is the primary workhorse of the fleet. The Air Force operates multiple blocks of the J-model, with the latest incorporating advanced fire control systems, improved sensors, and the ability to fire precision-guided missiles like the GBU-12 Paveway II and AGM-176 Griffin. The AC-130W Stinger II, an earlier modernization effort, brought similar precision strike capabilities to the fleet years before the J-model's full integration. Both variants allow a single aircraft to engage multiple targets simultaneously, drastically increasing their lethality compared to the earlier gun-heavy designs.
Modernization, Retirement, and Future Plans
The service has been gradually retiring the AC-130H Spectre variants over the past decade, reallocating resources to sustain and upgrade the J and W models. Looking ahead, the Pentagon has initiated the "Ghost Hunter" program, which will eventually replace the AC-130 with the next-generation Advanced Gunship System (AGS). This future aircraft, based on the MC-130J Commando II special operations tanker, is designed to be more survivable, have greater range, and carry an even more formidable suite of sensors and weapons. Consequently, the current fleet size is expected to remain relatively stable in the near term before gradually decreasing as the AGS comes online later in this decade.
Deployment and Readiness Considerations While the total number of airframes is important, the true measure of capability lies in how many are deployable at any given moment. Factors such as routine maintenance, pilot and aircrew training cycles, and depot-level overhauls mean that not every aircraft in the inventory is airborne-ready on a given day. During periods of heightened global tension, the Department of Defense may surge additional gunships from long-term storage to bolster forward-deployed units. This surge capability underscores why the total number of AC-130s in the U.S. inventory is a more relevant metric than the number actively flying on any single day. Strategic Value and Capabilities

AC-130s provide an unmatched combination of persistence, firepower, and precision that fixed-wing fighter aircraft cannot match in close support scenarios. Their ability to loiter for hours over a target area, using powerful side-firing cannons to engage threats with extreme accuracy, makes them invaluable in complex urban environments or against unconventional forces. The psychological presence of these "flying artillery pieces" often proves as significant as their destructive capacity, allowing ground commanders to shape the battlespace with controlled, overwhelming firepower when other assets are unavailable.
