Ukrainian long-range drone operations appear to have reached deep into the russian rear, with a reported strike on a petrochemical plant in Sterlitamak, Bashkortostan. The attack was carried out by operators of the 1st Unmanned Systems Center.
The strike was confirmed on April 15 by Robert Madyar Brovdi, commander of Ukraine's Unmanned Systems Forces. In his statement, he emphasized not only the physical damage inflicted but also the psychological effect of the operation, highlighting the vulnerability of targets deep inside russian territory.

According to Ukrainian sources, the targeted facility plays a significant role in supporting russia's defense industry. The petrochemical plant in Sterlitamak produces aviation fuel and additives for jet fuel, both of which are critical for sustaining air operations. Striking such production sites directly affects the operational capacity of russian aviation.
In addition, the facility is reportedly the only producer in russia of neodymium-based synthetic rubber. This material is used in specialized industrial and military applications, making the plant a unique and strategically valuable target within russia's industrial base.
The distance of the strike, estimated at around 1,500 kilometers from Ukrainian-controlled, underscores the growing reach of Ukraine's unmanned systems. Such range suggests continued improvements in drone endurance, navigation, and strike capabilities.
As Defense Express previously reported, Ukrainian forces carried out a coordinated night strike on April 14, targeting a series of high-value russian military sites in the temporarily occupied territory. The operation combined air-launched cruise missiles, guided bombs, and attack drones, reflecting a layered approach to striking both infrastructure and supply systems.
