The MQ-9 Reaper and its associated Predator-B family of drones are in an interesting spot these days. On one hand, they are receiving new, highly relevant capabilities and missions at an accelerating pace. They also just proved to be an absolutely star asset for hunting and killing key targets, such as missile launchers and air defenses, deep inside Iran. On the other hand, their vulnerability to air defenses, not even modern ones, is glaring, with major losses in Iran and Yemen. Yet the USAF’s chronic lack of commitment to replace the MQ-9 has left it with dwindling stocks and nothing better to do the job.

Within this jumbled and often misunderstood narrative, one new capability stands out from the rest that would give the MQ-9 extreme value today and for years to come. This is turning the MQ-9 into a radar-toting airborne early warning (AEW) platform for detecting and tracking aircraft, drones, and missiles. A Reaper in this exact configuration just flew for the first time recently.

The MQ-9 sortie in question was the product of a partnership between General Atomics and Saab, with Saab, already a leader in AEW systems, providing the podded radar system named LoyalEye. This initial test flight took place on May 19th, and a full demonstration of the pairing’s capabilities is planned for next year.

“AEW for MQ-9B will offer critical aloft sensing to defend against tactical air munitions, guided missiles, drones, fighter and bomber aircraft, and other threats. Operational availability for a medium-altitude, long-endurance UAS is the highest of any military aircraft, and as an unmanned platform, its aircrews are not put into harm’s way.”

For many years now, I have discussed how the most glaring new mission set for a medium altitude, long-endurance drone is AEW. The idea is relatively simple in concept. Take a cost-effective drone that can fly at medium altitudes for long periods and bolt on some radar pods capable of air moving-target indicator (AMTI) functionality. Then configure the datalinks (both line-of-sight and beyond line-of-sight) aboard the aircraft to send the information the pods collect back to controllers, who also remotely operate the drone and the pods from the ground. Such an unmanned aircraft could fly its missions at relatively low cost, and operate in a distributed manner, near where its surveillance capabilities are needed most. Above all else, it would be able to persist for very long periods of time — think of loitering over its launch location for the better part of a day or more — providing persistent long-range look-down radar surveillance, which has never been more important than it is today.

One-way attack munitions, also known as long-range kamikaze drones, are a massive threat to confront on many levels. These unmanned aerial systems blur the definition between cruise missiles and drones. In this case, cruise missiles are also part of the same problem set. While the question of how to shoot down relatively cheap one-way attack drones cost-effectively gets a lot of attention, just spotting them in order to engage them at all, especially at a distance, is also a challenge. Their small signatures and low-altitude flight profiles, as well as their slow speed, can make it so ground-based sensors don’t detect them until it’s almost too late, and aging airborne sensors also have limitations in doing so.
