The commander of an interceptor battalion in Ukraine’s 3rd Army Corps said his unit destroyed several thousand Russian aerial targets during Operation Vivaldi, ArmyInform, the Defense Ministry’s news agency, reported on 21 October.

Operation Vivaldi is a Ukrainian counteroffensive north of Lyman in Donetsk Oblast, where the 3rd Army Corps has reported liberating settlements. In its third phase, Ukrainian forces reclaimed five settlements and expanded their gains to 176 square kilometers. Strikes on Russian logistics and electronic warfare likely neutralized Russia’s drone defenses before Ukraine sent in armor, the Institute for the Study of War assessed.

The commander, who uses the callsign “Betsyk,” leads the interceptor battalion of the 1030th Anti-Aircraft Missile-Artillery Regiment “Aquila,” part of the 3rd Army Corps. He said Russian forces deployed large numbers of reconnaissance drones to locate Ukrainian positions after the corps began advancing.

Betsyk named Zala, Orlan, Supercam, Merlin, and Knyaz Veshchiy Oleg among the reconnaissance drones used by Russian forces.

Russia also brought in reinforcements and units operating strike drones, including first-person-view (FPV) quadcopters, Molniya fixed-wing FPV drones, and Lancet crews, he said. At one stage, Russian forces deployed crews from their Rubicon drone unit to disrupt the advance, but the move did not change the situation.

Betsyk said his battalion’s work deprived Russian forces of the ability to strike Ukrainian troops and track their movements.

Jet-powered Shaheds: speed is the main challenge

The regiment also works against Russian strike drones heading for targets behind the front line. Betsyk said interceptor crews had destroyed some jet-powered drones, but not in significant numbers.

The main difficulty is speed, he said. Interceptor drones need to reach 500–600 km/h to intercept Russian jet-powered attack drones, according to Betsyk.

For now, the regiment mainly uses conventional air-defense systems against these targets: self-propelled anti-aircraft systems, surface-to-air missile systems, and portable surface-to-air missile systems. Betsyk said these systems were historically designed to engage jet-powered targets.

He compared the current challenge with the early use of piston-powered Shaheds. Those drones initially posed a serious threat but later became easier for Ukrainian air defenses to counter. Russia has largely stopped using piston-powered Shaheds on most fronts since summer, he said, but continues to use piston-powered Gerbera drones, which are relatively cheap and can partly exhaust Ukrainian air defenses. The main drones Russian forces use now are jet-powered Shaheds, he said.

Betsyk expects Russian forces to adapt if Ukraine fields effective interceptors against jet-powered drones. They will seek ways to evade the interceptors, increase speed, improve navigation, and change their tactics, he said. However, he added that the battalion had not observed a major evolution so far and did not expect the drones’ speed to double.

What the corps says Vivaldi achieved

Separately, 3rd Army Corps commander Andrii Biletskyi said Ukrainian forces retook 277 square kilometers and 16 settlements during Operation Vivaldi, Ukrainska Pravda reported. Biletskyi also said Russian losses exceeded 8,000 personnel, according to ArmyInform. These figures are Ukrainian claims and have not been independently verified.

Russia's jet-powered attack drones could eventually reach 800–900 km/h, and intercepting them will demand new piloting skills—so Ukraine has asked the makers of its interceptor drones to build simulators to train the crews, a senior Air Force officer told a parliamentary commission on 6 October, Suspilne reported.

Russia keeps modifying its jet Shaheds faster than Ukraine can field the drones meant to catch them, and Kyiv is now preparing crews for speeds its interceptors have never faced—a sign the air war is shifting from a contest of volume to one of raw speed.

The speed Russia hasn't reached yet

Colonel Yurii Cherevashenko, deputy commander of Ukraine's Air Force, told the commission that Russia's jet drones fly at around 600 km/h today but could eventually reach 800–900 km/h—speeds he said have not been recorded so far. That range sits near the cruising speed of a commercial airliner.

Intercepting such targets will take specific piloting skills, Cherevashenko said. When an interceptor and its target move at roughly the same speed, he noted, the pilot barely perceives the difference in their speeds. To train for that, Ukrainian interceptor-drone makers have been tasked with building simulators where crews can practice against high-speed targets.

Where Ukraine stands now

Ukraine already downs 85% to 90% of Russia's slower, propeller-driven drones, Ukrainian President Volodymyr Zelenskyy has said, but the jet models remain a tougher problem—Ukrainian interceptors scored their reportedly first kill of a jet-powered Shahed in November 2025. In a 28 September evening address, Zelenskyy put the jet-drone interception rate at about 57%, lower than required. Days later, he said Ukraine is testing five interceptor-drone models and could be producing about 400 of one of them by the end of October. Asked when jet-drone interceptors would arrive at the scale needed, Cherevashenko answered: "Not before the end of November."
