US Air Force Integrates GBU-39 SDB on MQ-9 Reaper for Long-Range Precision Strike

The US Air Force has integrated the GBU-39B Small Diameter Bomb onto the MQ-9 Reaper, expanding the drone’s strike profile with a low-collateral-damage precision munition. Initial work is being driven by the 27th Special Operations Wing at Cannon Air Force Base, New Mexico.

According to The Defense Post’s 25 May 2026 report, the MQ-9 Reaper has been reconfigured as a strike platform able to carry and release the GBU-39B SDB with precision. Initial integration testing was conducted at Cannon AFB by the 27th Special Operations Wing.

GBU-39B SDB: 113 kg body, 110+ km glide reach

Open-source data describe the GBU-39B Small Diameter Bomb as a Boeing-built 113 kg-class precision-guided weapon. With its pop-out wings, the bomb can glide more than 60 nautical miles (≈110+ km) when released from altitude. The GPS/INS-guided SDB-I variant sits alongside the SDB-II (StormBreaker), which adds a tri-mode seeker for moving targets. The bomb’s compact warhead (≈22.7 kg explosive fill) minimises collateral damage in urban or constrained operational zones.

This integration moves the MQ-9 off its Hellfire / Paveway / JDAM-only profile and into a new role enabling multi-target prosecution in a single sortie. A Reaper carrying SDB four-pack racks on external stations can engage several targets per pass.

Special operations support concept

The article frames the new capability around “fire support, infiltration and resupply” tasks in contested environments. The SDB’s long glide reach lets the MQ-9 deliver effects without driving the airframe into contested low- and medium-altitude air-defence rings — a critical answer to the losses MQ-9s have taken in Yemen and Syria as adversary IADS thickens.

Turkish industry perspective

The Turkish defence industry already covers the same integration envelope on indigenous platforms:

AKINCI — high-altitude, long-endurance UCAV cleared with TÜBİTAK SAGE’s NEB / KGK and Roketsan’s SOM-A
AKSUNGUR — twin-engine UCAV qualified with MAM-T, MAM-L, KGK-SİHA and SOM-A
KGK-SİHA — Türkiye’s 250 kg-class wing-kit glide bomb, the functional analogue of GBU-39
MAM-T — extended-range micro-munition family

KGK-SİHA in particular is the closest Turkish functional peer to GBU-39. AKINCI and AKSUNGUR have demonstrated multi-glide-bomb carriage publicly. This sets up Türkiye as a direct competitor to the MQ-9 + GBU-39 package in export markets where US foreign military sales remain politically constrained.

Next steps

Cannon AFB is expected to continue acceptance testing, with broader operational fielding likely in the coming months. Detailed coverage is available through The Drone Front publication referenced in the source article.
