U.S. Air Force Special Operations Command has armed MQ-9 Reaper drones operated by the 27th Special Operations Wing at Cannon Air Force Base with the GBU-39B Small Diameter Bomb, significantly increasing the aircraft’s ability to strike high-value targets from safer stand-off ranges in contested environments. The integration, recently highlighted by the U.S. Air Force, strengthens the Reaper’s role in supporting special operations missions where survivability, precision, and rapid response are critical amid enemy air defenses.
The GBU-39B provides the MQ-9 with a compact precision-guided weapon capable of striking fortified or mobile targets with reduced collateral damage, enabling operators to conduct accurate strikes in dense or sensitive combat areas. The upgrade reflects a broader shift toward arming unmanned systems with longer-range and more survivable precision weapons to maintain operational effectiveness against increasingly advanced adversaries.

The capability was officially highlighted on May 19, 2026, by the 27th SOW as part of Air Force Special Operations Command’s broader effort to adapt to increasingly dense air defense threats and evolving battlefield requirements. The integration strengthens the MQ-9’s survivability and operational flexibility by allowing strikes from outside the engagement envelope of many ground-based air defense systems, improving both force protection and mission persistence.
Developed by General Atomics Aeronautical Systems, the MQ-9 Reaper is a remotely piloted aircraft designed primarily for intelligence collection and precision strike missions against time-sensitive targets. Larger and significantly more powerful than the earlier MQ-1 Predator, the Reaper is powered by a Honeywell TPE331-10GD turboprop engine delivering 900 shaft horsepower and can remain airborne for extended periods while carrying a payload of up to 3,750 pounds.
The MQ-9 combines persistent surveillance capabilities with precision attack functions, allowing it to conduct intelligence, surveillance and reconnaissance, close air support, convoy overwatch, combat search and rescue, target designation, and precision strike missions simultaneously. Its Multi-Spectral Targeting System integrates infrared sensors, daylight television cameras, shortwave infrared imaging, laser designation, and synthetic aperture radar, enabling crews to detect, track, and engage targets in all weather conditions.
Traditionally armed with AGM-114 Hellfire missiles and laser-guided bombs such as the GBU-12 Paveway II, the MQ-9 now gains a major increase in standoff attack capability through the addition of the GBU-39B. Unlike shorter-range direct attack weapons, the Small Diameter Bomb enables the Reaper to strike targets while remaining at safer distances from hostile air defense systems, a critical advantage in modern high-threat operational theaters.
The GBU-39B Small Diameter Bomb was developed under the U.S. Department of Defense Small Diameter Bomb program to provide highly accurate low-collateral precision effects in urban and contested combat environments. Entering service in 2006, the weapon introduced a new operational concept focused on strike density, survivability, and precision target discrimination rather than relying solely on larger blast effects.
Weighing approximately 129 kilograms (285 pounds), the GBU-39B uses deployable graphite-epoxy wings that unfold after release, allowing the munition to glide more than 110 kilometers when launched from high altitude. Its compact dimensions enable multiple weapons to be carried on a single aircraft using smart carriage systems such as the BRU-61/A or the BRU-78 dual carriage rack developed specifically for the MQ-9 Reaper.
The weapon uses a GPS-aided inertial navigation system combining a Honeywell HG1700 ring-laser gyroscope inertial measurement unit with a SAASM-enabled military GPS receiver hardened against jamming and spoofing. Adaptive flight correction algorithms continuously adjust the munition’s trajectory during flight, allowing the bomb to maintain a circular error probable of less than five meters even in GPS-degraded environments.
Its standard penetrating blast-fragmentation warhead is designed to defeat hardened structures, including reinforced bunkers, aircraft shelters, and protected command facilities. Equipped with a delayed-action fuze, the bomb can penetrate more than one meter of reinforced concrete before detonation, maximizing internal destructive effects while minimizing unnecessary blast damage outside the target area.
The GBU-39 family also includes specialized variants such as the Focused Lethality Munition equipped with a carbon-fiber casing and Dense Inert Metal Explosive filler designed to sharply reduce fragmentation effects during strikes in urban environments. Newer software-enhanced variants feature improved resistance against electronic warfare and greater navigation resilience in contested electromagnetic conditions.
According to Lt. Col. Joshua Swann, an MQ-9 squadron commander assigned to the 27th SOW, the new capability directly addresses operational challenges posed by adversaries increasingly relying on layered denial systems and modern integrated air defenses. By combining the Reaper’s long-endurance surveillance capability with the GBU-39B’s precision standoff strike profile, AFSOC gains a more survivable and flexible asset capable of supporting distributed special operations forces deep inside contested battlespaces.
The integration also reflects a broader transformation of unmanned aerial warfare. Originally optimized for permissive counterterrorism operations, the MQ-9 Reaper is progressively evolving into a more relevant system for high-intensity conflict scenarios against peer and near-peer adversaries. Long-range glide munitions such as the GBU-39B reduce the aircraft’s exposure to short- and medium-range air defense systems while allowing operators to maintain persistent ISR coverage and precision strike capability over large operational areas.
The operational value of this capability is particularly important for multidomain operations where precision effects, target persistence, and rapid engagement cycles are essential. By allowing the MQ-9 to carry larger numbers of compact precision-guided munitions while maintaining long loiter times, the integration significantly improves the aircraft’s ability to support joint force commanders during both irregular warfare missions and large-scale conventional combat operations.
Air Force Special Operations Command’s MQ-9 Reaper fleet officially became operational with the GBU-39B Small Diameter Bomb during the spring of 2026, marking a major milestone in the evolution of U.S. remotely piloted strike capabilities. The combination of the Reaper’s endurance, advanced sensor suite, and the GBU-39B’s long-range precision engagement profile provides AFSOC with a more survivable and operationally flexible strike asset capable of supporting special operations forces across increasingly contested battlespaces.
