**Deck**: Ukrainian drones hit the Iskra Electronics Plant in Ulyanovsk in a concentrated strike, damaging a producer of military and industrial electronics while nearby residential areas were also hit. The attack came amid a broader barrage on Russian territory that injured civilians and targeted refineries and chemical plants.

A Ukrainian drone strike on the Iskra Electronics Plant in Ulyanovsk has brought Russia’s defence‑industrial facilities deeper into the conflict, damaging a site that produces key electronic components and communications equipment.

Video from 25 September shows six consecutive drone strikes on different parts of the Iskra complex in Ulyanovsk. The plant specialises in electronic components, radio‑electronic equipment and communications systems for both military and industrial sectors, placing it within the supply chain that supports Russian forces.

Regional authorities in Ulyanovsk reported that industrial and civilian infrastructure, including residential buildings, was damaged in the overnight attacks. Eight people, including a child, were injured. Officials did not immediately separate damage to Iskra itself from damage to surrounding sites, but the incident showed how closely packed industrial and residential areas are in the city.

Russia’s defence ministry said its air defences shot down 592 Ukrainian drones overnight across Russian regions and over the Black Sea. That figure can’t be independently confirmed from available reports, but it would represent a very large drone salvo if accurate. Despite the reported shoot‑downs, strikes on facilities such as Iskra and injuries in Ulyanovsk indicate that some drones got through.

The attack on Iskra was part of a wider pattern of Ukrainian strikes on Russian industrial infrastructure. On the same morning, Ukrainian long‑range drones hit the Permnefteorgsintez oil refinery in the city of Perm, causing several large fires at a plant that can process up to 13 million tons of crude oil per year and is ranked as Russia’s seventh‑largest refinery.

Ukrainian drones also struck the Voronezhsintezkauchuk synthetic rubber plant in Voronezh, setting off a fire at a facility that produces thermoelastoplasts and synthetic rubbers. In occupied Luhansk City, mid‑range Ukrainian drones hit the Stroycenter shopping centre, leading to a large fire there as well.

Taken together, the strikes on Iskra, Permnefteorgsintez, Voronezhsintezkauchuk and the Stroycenter shopping centre demonstrate that Ukrainian planners are willing to reach far beyond front‑line regions to hit fuel, materials and electronics production, alongside commercial sites in Russian‑held territory.

The key questions now are how extensive the damage is at the Iskra Electronics Plant and other affected facilities, how quickly Russia can restore production, and whether Moscow moves to disperse or reinforce protection of similar defence‑linked plants in Ulyanovsk and other interior regions.
