Ukraine's 413th Separate Raid Regiment of the Unmanned Systems Forces struck the Snizhne Machine-Building Plant in occupied Donetsk Oblast in September, working with other Defense Forces units, the regiment posted on 6 October, sharing a video of the strike. The General Staff reported the strike on the plant on 11 September, saying that the extent of the damage was being clarified.

The strike adds to Ukraine's campaign of long-range attacks on Russian military targets as Russia has begun its winter campaign of strikes against Ukraine's energy infrastructure. Hitting the suppliers of aircraft parts goes after Russia's ability to keep its attack jets and helicopters flying.

The regiment said the plant works for Russia's military industry, producing engine components for attack aircraft and combat helicopters.

A former Motor Sich plant in occupied Snizhne

The Snizhne plant was a separate division of Motor Sich, a Ukrainian aircraft-engine maker based in Zaporizhzhia, a city that remains under Ukrainian control. Snizhne has been under Russian occupation since 2014. The plant specializes in producing parts for gas-turbine engines, including compressor and turbine discs and blades, the General Staff said. It never built whole engines. In September 2014, months into the occupation, it was machining blanks from Motor Sich's Zaporizhzhia plant into turbine blades and was one of only two plants in the former Soviet Union making such blades for helicopters, a plant worker said.

Motor Sich said in December 2017 that it had lost control of the plant. Weeks later, Viacheslav Bohuslaiev, then Motor Sich's honorary president and a member of parliament, told RFE/RL's Donbas.Realii that Motor Sich still owned the plant and had handed its management to a foreign company, while keeping it under the company's "full control."

In February 2023, Ukraine's Prosecutor General's Office served Bohuslaiev a notice of suspicion of aiding a terrorist organization, alleging that Motor Sich shipped blanks to the Snizhne plant and received finished engine parts through foreign-registered companies. The case went to court in October 2023, and Bohuslaiev, who denies the charges, has been in pretrial detention since October 2022 as the trial continues.

Snizhne, which Russia uses as a rear base, has been hit before. In May, Ukraine's Unmanned Systems Forces and the Security Service of Ukraine struck a Russian training center for drone pilots in the city, and in September, a strike on energy infrastructure cut power across Snizhne.

Ukraine's drone pilots are killing and wounding far more Russian infantry than they did a month ago. Ukraine's Unmanned Systems Forces confirmed that their pilots took out 2,699 Russian infantry from 1 to 5 October, 39.7% more than in the first five days of September, Commander Robert "Madiar" Brovdi wrote on Telegram on 6 October.

The Unmanned Systems Forces, the branch of Ukraine's military that fights with drones, count only losses verified by their own pilots in the military's Delta system, so the full picture of Russian losses is larger, Brovdi stressed. Compared with the first five days of August, the rise is 76.5%, from 1,529 losses, which he ties to denser and more frequent Russian assaults.

The sharpest growth occurred in the area of the 1st Azov Corps of Ukraine's National Guard on the Dobropillia-Pokrovsk axis in Donetsk Oblast, as fighting for fortress-belt cities continues. Drone pilots recorded 1,268 Russian losses there, 43% more than the 884 of early September and 91% more than the 664 of early August.

"Russia's hidden mobilization is in action. This is the beginning," Brovdi said ironically.

Russia doubles its monthly recruitment pace

Russian recruitment, mobilization, and contracts run at about 70,000 people a month, twice the 35,000 monthly average from January to August 2026, Brovdi noted on 16 September, when he forecast 12,500 losses for his pilots in September.

He expected the toll to keep climbing. Bigger records still lie ahead because of Russia's unannounced mobilization, Brovdi added on 24 September.

Drone pilots outpaced August by a quarter

September was completed above that forecast. The pilots logged 13,358 Russians killed or wounded, 25.35% more than the 11,010 of August, an average of 445 a day against 355, Brovdi reported. By his count, that equals the full assault infantry of one battalion every day, and his pilots hit a Russian target every 42 seconds.

Two sets of axes took the heaviest toll. In the first 24 days of September, the Dobropillia and Pokrovsk axes accounted for 4,018 losses, and the Oleksandrivka and Huliaipole axes for 3,021, according to Brovdi. The first of those groups covers the same Dobropillia-Pokrovsk axis where the Azov corps zone recorded the sharpest October rise.
