Russian industrial sites are increasingly turning to makeshift defenses against Ukrainian long-range drone attacks—most notably, a new type of protective frame known as the KOZ-U-Sh, according to Defense Express on October 12.
The Moscow-based company Amast Power Lines disclosed that it has produced around 150 KOZ-U-Sh structures, which are being installed over key oil and fuel storage facilities to reduce the risk of drone impact.
The company describes the system as a “universal support construction” made of vertical steel cables covered with a gabion mesh, designed to shield storage tanks ranging from 400 to 50,000 cubic meters.
According to the manufacturer, the KOZ-U-Sh is meant to protect targets from unmanned aerial vehicles weighing up to 200 kilograms.
However, Defense Express notes that many Ukrainian drones used in recent deep strikes—such as the An-196 “Liutyi”, which has a launch mass of around 250–300 kilograms—could exceed those limits and penetrate the netting.
Despite claims that the structures have prevented some drone impacts, video evidence circulating online shows several Russian oil refineries covered with wire nets still suffering direct hits from Ukrainian long-range drones.
Ukraine’s Defense Forces have continued their campaign against Russia’s energy infrastructure, striking fuel depots, gas plants, and refineries almost daily.
According to Defense Express, the Russian industry’s adoption of systems like KOZ-U-Sh reflects an effort to slow, rather than stop, these increasingly precise attacks.
Earlier, intelligence cooperation between Washington and Kyiv intensified after a July phone call between US President Donald Trump and Ukrainian President Volodymyr Zelenskyy, during which Trump reportedly asked if Ukraine could strike Moscow if provided with long-range weapons.
