US Air Force Integrates GBU-39 SDB with MQ-9 Reaper: Long-Range Precision Strike

The U.S. Air Force has integrated the MQ-9 Reaper drones with the GBU-39B Small Diameter Bomb (SDB), known for its low collateral damage profile. Operational tests are being conducted by the 27th Special Operations Wing in New Mexico.

According to a report by The Defense Post dated May 25, 2026, the MQ-9 Reaper is being repositioned as an attack platform capable of carrying and precisely releasing the GBU-39B SDB. The pre-integration tests were conducted by the 27th Special Operations Wing stationed at Cannon Air Force Base in New Mexico.

GBU-39B SDB: 113 kg body, profile extending to 110+ km range

According to open-source data, the GBU-39B Small Diameter Bomb is a precision-guided bomb family produced by Boeing, weighing approximately 113 kg. With its foldable wing system, it can glide for over 60 nautical miles (≈110+ km) when released from high altitude. In addition to the GPS/INS-guided SDB-I variant, the SDB-II (StormBreaker) variant is equipped with a multi-mode seeker for engaging moving targets. The bomb’s small body (≈22.7 kg explosive fill) minimizes collateral damage in urban or crowded operational areas.

With this integration, it appears that the MQ-9 has acquired a new profile capable of delivering staggered strikes on multiple targets, different from the Hellfire / Paveway / JDAM axis. A Reaper can hit multiple targets in the same sortie with quadruple SDB carrying pylons on external stations.

Special forces support concept

The report indicates that the system is intended for use in “fire support, infiltration, and resupply” missions in contested environments. The long-range glide capability of the SDB means that the MQ-9 can affect targets without entering low/medium altitude air defense zones. This is a critical step in light of the recent operational losses experienced by the MQ-9 in areas like Yemen and Syria, where air defenses have been developed by the enemy.

Turkey perspective: AKINCI, AKSUNGUR, and Turkish munitions similar to SDB

The Turkish defense industry has already built a similar integration framework on domestic platforms:

AKINCI — A high-altitude, long-range UAV capable of carrying TÜBİTAK SAGE produced NEB / KGK and SOM-A
AKSUNGUR — A twin-engine UAV integrated with MAM-T, MAM-L, KGK-SİHA, SOM-A
KGK-SİHA — A Turkish-made 250 kg class winged glide bomb, a functional equivalent of the GBU-39
MAM-T — An extended-range micro munition family

Especially the KGK-SİHA stands as the closest functional counterpart to the GBU-39 for the Turkish aerospace industry. Capacity tests conducted on AKINCI and AKSUNGUR have concretely demonstrated the multi-glide bomb carrying configuration. This opens the way for a direct competitor to the U.S. offering of the MQ-9 + GBU-39 package in export markets.

Next steps

The report stated that Cannon Air Force Base will continue acceptance testing and that the transition to operational inventory could occur in the coming months. It was mentioned that more comprehensive data could be followed through The Drone Front publication.
