Ukrainian strikes hit Azov optical-mechanical plant, Ilysky refinery, and Russian air-defense assets overnight

Why it matters

The Azov plant is one of Russia's key optical-mechanical and opto-electronic facilities, producing seeker heads and guidance components used across multiple Russian missile programs. Open-source analysts at Dallas Analytics link AOMZ to at least seven programs — including the Kh-101 cruise missile, the R-37M air-to-air missile, the Kh-35U, Kh-59/Kh-69, Kh-31P, and the Oreshnik ballistic system — making a sustained hit there a meaningful pressure point on Russia's precision-weapons supply chain. The simultaneous strike on the Ilysky refinery, a Pantsir-S2, and occupied-territory targets such as the P-18 Terek radar reflects a widening Ukrainian long-range campaign against Russian military-industrial and energy infrastructure deep inside Russian territory.

What happened

On the night of 25–26 September 2026, Ukrainian Defense Forces carried out a series of long-range strikes. The main target was the Azov Optical-Mechanical Plant in the city of Azov, Rostov Oblast, where a fire broke out in the foundry shop and equipment in five production buildings was damaged; the SBU said the attack also damaged optical and foundry production facilities, an assembly section, a galvanic shop, and a printed-circuit-board workshop. The SBU's Alpha Special Operations Center and the Ukrainian Navy carried out the strike using Neptune cruise missiles alongside Ruta, Palyanytsya, and Bars jet drone-missiles. In the same area, Ukrainian forces hit railway tankers carrying fuel and lubricants in Azov and a Russian Pantsir-S2 air-defense missile-and-gun complex in Rostov Oblast.

Further afield, the SBU struck the Ilysky oil refinery in Krasnodar Krai, where two fire sources were recorded — near the tank farm and the ELOU-AVT unit. On 25 September and overnight into 26 September, Ukrainian forces also struck an ammunition depot in Sievierodonetsk, Luhansk Oblast, and a P-18 Terek mobile meter-wave radar near Semenivske in Donetsk Oblast. President Volodymyr Zelensky confirmed the strikes publicly, and the General Staff of the Armed Forces of Ukraine described the operation as the exercise of Ukraine's inherent right to self-defense under Article 51 of the UN Charter, aimed at reducing Russia's military-economic potential.

How Ukrainian sources describe it

Ukrainian sources lead with the General Staff of the Armed Forces of Ukraine and the SBU as the confirming authorities, highlighting the Alpha Special Operations Center and the Ukrainian Navy as the strike force and naming the weapons used — Neptune cruise missiles together with Ruta, Palyanytsya, and Bars jet drone-missiles. Coverage emphasizes the strategic value of AOMZ as a KTRV facility linked to missile guidance and precision weapons, citing Dallas Analytics' finding that the plant sits in the production chains of at least seven Russian missile programs, including Kh-101, R-37M, and Oreshnik. The General Staff framed the strike as Ukraine exercising its right to self-defense under Article 51 of the UN Charter. President Zelensky's public confirmation is presented as a signal of Ukraine's operational reach into Russia. Ukrainian reporting also provides technical detail on the P-18 Terek radar — a mobile meter-wave system with a detection range of about 250 km and altitude up to 35 km — to underscore the significance of the occupied-territory hits.

How international sources describe it

The single non-Ukrainian source in this set, an Azerbaijani English-language agency wire, reports the Azov strike in a shorter, factual register. It notes the strike and local Russian accounts of damage to industrial facilities but does not engage with the Article 51 self-defense framing, the KTRV context, or the Dallas Analytics tracing of AOMZ to specific missile programs. The focus stays on the strike itself and on Russian-side damage reports rather than on the strategic or legal framing that dominates Ukrainian coverage.

Where reporting differs

Sources do not fully agree on the weapons used against AOMZ: some name only Neptune, Ruta, and Palyanytsya, while others add the Bars jet drone-missile. Sources also differ on whether the ammunition depot strike in Sievierodonetsk and the P-18 Terek radar strike in Donetsk Oblast are presented as part of the same 25–26 September overnight operation as the Azov plant strike or as a separate set of overnight strikes reported alongside it.

Background

The Azov Optical-Mechanical Plant is part of Russia's Tactical Missiles Corporation (KTRV) and produces radar and infrared seeker heads for guided missiles, thermal-imaging devices, and electronic systems for precision artillery. Open-source analysts at Dallas Analytics, working from internal correspondence, state-contract materials, and cooperation schedules covering April 2023 to March 2025, traced AOMZ to at least seven Russian missile programs, with a 2025 component-base program valued at 583.6 million rubles, of which 497.6 million had been paid out as advances. The plant had previously been struck by drones on the night of 4 July 2025, according to Andriy Kovalenko, head of the Center for Countering Disinformation at the National Security and Defense Council. The P-18 Terek is a mobile two-coordinate meter-wave radar used in Russian air-defense radar support, with a maximum detection range of about 250 km and altitude up to 35 km. The Ilysky strike follows Ukrainian strikes on oil refineries in Perm Krai and Rostov Oblast on 24–25 September, putting it in a series of long-range attacks on Russian energy and military-industrial infrastructure.
