Ukraine Makes World-First Airborne Robot Assault Behind Russian Lines During Counteroffensive

Ukraine deployed attack ground robots from heavy bomber drones more than 10 kilometers behind Russian lines during a counteroffensive in northern Donetsk region—a tactic the Third Army Corps described as a world first.

According to Ukraine’s Third Army Corps on September 21, the airborne deployment was carried out during the second phase of Operation Vivaldi, with heavy drones operated by the Third Assault Brigade carrying unmanned ground vehicles, or UGVs, deep into the Russian rear.

The operation effectively turned the ground robots into payloads for larger aerial drones. Instead of traveling across kilometers of contested terrain to reach Russian positions, the UGVs were flown over the front and deployed closer to their targets.

Third Army Corps commander Brigadier General Andrii Biletskyi said Ukrainian forces were the first in the world to deploy ground robotic systems in this way, with the attack UGVs transported more than 10 kilometers behind enemy lines.

“Wars are won by infantry, but we protect our infantry. That is why robots go to the enemy first,” the Third Army Corps said.

The robot deployment formed part of a broader operation designed to disrupt Russian defenses before Ukrainian troops advanced. The Corps said Ukrainian air defense and electronic warfare systems interfered with Russian reconnaissance drones, preventing them from detecting the plan of the offensive.

At the same time, Ukrainian artillery and unmanned systems struck Russian command posts, communications nodes, logistics routes, crossings, and reserves.

Ukraine’s 3rd Army Corps Recaptures 125 Sq Km in "Operation Vivaldi" in Donetsk Region

Sep 20, 2026 12:52

According to the Third Army Corps, Ukrainian forces cleared another 40 square kilometers during the second phase of Operation Vivaldi. Ukrainian troops regained control of Shandryholove and Derylove and established control over Drobysheve in the Lyman sector, the Corps said.

Since the beginning of Operation Vivaldi, more than 125 square kilometers have been brought under Ukrainian control, according to the Corps. It also reported more than 3,000 Russian personnel losses and said the operation disrupted Russian attempts to transfer significant forces toward the Kupiansk sector.

The latest operation, however, marked what the Third Army Corps described as the first time attack UGVs had been air-deployed more than 10 kilometers into the enemy rear as part of an offensive operation.

Air deployment can bypass some of the main obstacles facing ground robots. A UGV traveling independently toward a target can encounter mines, artillery fire, FPV drones, difficult terrain, and Russian reconnaissance before reaching its operating area.

The concept of transporting Ukrainian ground robots with other unmanned platforms predates Operation Vivaldi. Ukrainian forces have previously experimented with carrying UGVs by heavy drones, including the delivery of an ARK-1 ground robot behind Russian lines.
