Ukrainian long-range one-way attack drones have carried out some of the deepest strikes of the war so far, hitting critical industrial sites deep inside Russian territory — more than 1,700 kilometers from the Ukrainian border — in what Kyiv officials say demonstrates a rapidly advancing domestic drone capability.
Unmanned systems struck two major targets in recent days: the Orsknefteorgsintez oil refinery in the city of Orsk, Orenburg region, approximately 1,400 kilometers from Ukraine, and the Azot chemical plant in Berezniki, Perm region, around 1,700 kilometers from the border. Both facilities are considered strategically important to Russia’s energy and defense sectors.
The refinery in Orsk is one of Russia’s key oil processing centers, supplying fuel to both civilian markets and military logistics networks. The Azot plant in Berezniki is one of the country’s largest producers of industrial explosives, supplying mining operations and defense-related industries.
Ukraine’s Unmanned Systems Forces were behind the strikes employing upgraded versions of the domestically produced “Liutyi” (“Fierce”) one-way attack drone. The new iteration of the drone reportedly features extended range and improved navigation capabilities, enabling precision attacks at unprecedented distances.
The strikes mark a major milestone in Ukraine’s long-range strike campaign, underscoring the evolving role of domestically produced unmanned systems in targeting critical infrastructure deep within Russian territory.
