Plumes of smoke rose near the Chelyabinsk Metallurgical Plant on April 25 after a long-range drone struck deep within the Russian interior. Ukrainian forces have expanded their kinetic attrition strategy, conducting strikes against Yekaterinburg and Chelyabinsk City, located approximately 1,600 to 1,700 kilometres from the international border. Chelyabinsk Oblast Governor Alexey Teksler claimed that Russian forces repelled a Ukrainian drone strike against unspecified infrastructure in the oblast. Geolocation footage from Yekaterinburg showed structural damage to an apartment building. The Kremlin newswire TASS claimed that Ukrainian forces utilised an FP-1 long-range drone launched from Kharkiv Oblast. This unprecedented geographical reach demonstrates a systemic vulnerability in the Russian industrial heartland. By targeting the logistical and manufacturing arteries deep within the Federation, Kyiv is attempting to impose a severe domestic economic cost on Moscow's war effort, bypassing the hardened military targets on the immediate front lines.
