Ukraine is lofting its AI drones 8,000 meters up—then letting them glide into Russia

Ukraine's AI drones are ranging as far as 200 km from the disputed gray zone, hunting down Russian supply trucks and wreaking havoc on Russia's front-line logistics as Ukrainian forces fight to delay, or at least deplete, the Russians' large-scale spring offensive.

And soon those high-tech new drones, including the Hornet, B-2 and other models, could range much farther with the help of a very old low technology. Balloons.

That could turn Ukraine's middle-strike drones into deep-strike drones, massively expanding the area in occupied Ukraine and adjacent Russian oblasts where AI drones can pluck at Russian logistics. The deeper the logistical raids, the weaker Russian regiments would be as they launch assaults across the gray zone without all their supplies and reinforcements.

On Wednesday, footage circulated depicting Ukrainian developers testing a balloon-launched Hornet. The helium-filled balloon lofted the 2-m Hornet as high as 8,000 m before releasing it. The drone then glided down toward the ground, waiting to fully engage its electrically powered propeller.

The combination of a balloon assist and a lengthy glide would greatly extend, perhaps even double, a Hornet's 200-km range.

Balloon-launched drones were probably inevitable as Russia's wider war on Ukraine grinds into its 51st month. Both sides already use balloons — Russia to extend the range of radio networks, Ukraine to sow havoc over Russia with payload drops and to distract Russian air defenses during drone raids. The launch platform was the logical next use.

But balloons give and they take. Yes, a balloon costing just a few thousand dollars is an inexpensive way of carrying a small payload potentially hundreds or even thousands of kilometers. But balloons are at the mercy of the wind, and the wind patterns high over Ukraine don't always point into occupied territories and Russia itself.

Balloon forces can only wait until conditions are favorable. And even when they are favorable, the winds may constrain the attackers, forcing them to attack from certain points toward certain points.

🇺🇸 The U.S. Hornet kamikaze drone has been tested using a balloon-assisted launch system, with the balloon carrying the drone 42 kilometers before releasing it from an altitude of 8 kilometers while using only 5% of its battery.

The comms problem

There are other constraints besides the wind. A drone is only as useful as the command and control network that supports it. The most advanced Ukrainian AI drones such as the Hornet have onboard algorithms that can recognize certain targets (military cargo trucks, for instance) and autonomously steer the explosive drones into their targets.

But even these drones have remote human operators who help fly them toward their target zones, and who click buttons approving the drones' targets. Until Ukraine deploys fully autonomous drones, it'll need to extend its communications at the same pace it extends its drone strikes.

That can mean a lot of things. Starlink satellite terminals provide connectivity across occupied Ukraine but don't work in Russia (as a matter of policy by the Elon Musk-controlled company) and are also vulnerable to Russian jamming. Mesh radio networks made up of many connected senders and receivers are harder to jam but require a lot more hardware. Some drones can piggyback on Russia's own 5G cellular networks, but Russian authorities work hard to block unauthorized 5G devices including Ukrainian drones.

A balloon drone can't just range thousands of kilometers into Russia if there isn't a radio network ranging just as far. Yes, Ukraine deploys fully autonomous attack drones that can range deep inside Russia thanks to their self-contained inertial navigation systems, but these large drones don't need help from balloons to travel a thousand kilometers or farther.

No, balloons are clearly optimized for carrying smaller middle-strike AI drones and nudging them closer to Russian oblasts. If Ukrainian developers are working on drone comms as hard as they're working on alternative launch methods, A.I. drones could soon strike twice as far.

The easiest solution to the comms problem might be the most obvious: add radio relays to the balloons themselves.
