Drone strike on Sibur plant in western Siberia

did the shutdown affect export shipments or just domestic supply?
Calling this a 'significant leap' assumes the drone was launched from Ukrainian territory. If it was launched from inside Russia by partisans, the operational reach hasn't actually changed.
Sibur is a critical bottleneck for Russian polymer production. Shutting it down ripples through their entire plastics industry, which is a practical win regardless of the launch point.
This fits the pattern since Kyiv shifted to targeting oil refineries and bombers. The deep strike capability is becoming a feature of the strategy, not a one-off event.
What if the objective is to force a reallocation of air defenses? Moving batteries into the interior to protect plants like Sibur could create vulnerabilities at the front.
