A Ukrainian attack on 4 July targeted a key Russian defense facility in the city of Azov, Rostov Oblast, about 200 km from the frontline. The Azov Optic-Mechanical Plant, which manufactures critical electronic components for Russian missiles and armored vehicles, was hit by multiple drones in a bold daylight assault. The extent of the damage is currently unknown.

Morning drone strike hits Azov military facility

According to Militarnyi, the attack occurred on the morning of 4 July when Ukrainian strike drones launched an assault on the Azov Optic-Mechanical Plant, part of Russia’s Tactical Missile Armament Corporation.

Social media footage showed fixed-wing UAVs diving toward the site, followed by explosions and visible smoke. One of the drones bore a delta-wing “Shahed-like” structure, suggesting the use of an unknown new UAV model.

The original Shaheds are Iranian-designed long-range explosive drones that Russia uses in its daily attacks on Ukrainian cities. They are easily recognizable by their rounded nose and triangular, delta-shaped wings.

Witness footage and drone type

Ukrainian Telegram channel Exilenova+ posted an image, showing a delta-wing drone with the caption:

“Rostov. Likely a new UAV from Ukraine’s Defense Forces.”

Later, the same channel shared videos capturing different UAV types, including a well-known Ukrainian drone and a delta-wing aircraft believed to be a new model.

“Azov was attacked by several types of birds,” Exilenova+ commented. “We see an FP-1 pass over, and then, probably, the strike of that same ‘new’ drone.”

Militarnyi noted that “Delta-wing drones are fairly common, but they are rarely used by those attacking the aggressor country. What specific model was used remains unknown at this time.”

At least 10 drones

Russian authorities initially claimed their air defense forces intercepted the drones. Russian Telegram channel Astra reported that at least ten UAVs or their debris “fell” on the factory grounds. The local emergency services confirmed the site was impacted on 4 July.

Yury Slyusar, acting governor of Rostov Oblast, stated that evacuation efforts were underway due to widespread damage from UAV debris, claiming that the attack damaged residential buildings. While initial reports suggested no injuries, Slyusar had also stated that one woman killed in the overnight attack.

The Russian Ministry of Defense claimed  that air defenses downed 26 drones over Rostov Oblast overnight on 4 July. In Shakhty, a UAV strike allegedly caused a transformer substation to shut down, leaving around 2,000 homes — with more than 6,000 residents — without power. Buildings near the substation also suffered window damage.

Targeted facility and its military role

The Azov Optic-Mechanical Plant is a core producer of high-precision electronics, optical, and thermal imaging equipment for Russia’s military. As detailed by Exilenova+, it manufactures lenses, prisms, radar homing heads, and control systems used in tanks, infantry fighting vehicles, naval systems, and aircraft.

Ukraine’s Center for Countering Disinformation, under the National Security and Defense Council, confirmed the strike. Its head, Andrii Kovalenko, emphasized that the plant produces “eyes” for Russian military hardware, including fire control systems and rangefinders. He stated,

“Despite a difficult night (a reference to Russia’s massive missile and drone attack on Kyiv, – Ed.), there is good news. In Russia, targets were hit in Moscow and Rostov oblasts. The Azov Optic-Mechanical Plant was struck.”

The facility has been under US sanctions since March 2022 due to its role in the Russian war effort. It is also sanctioned by Canada, Switzerland, the European Union, New Zealand, and Ukraine. The Ukrainian Defense Intelligence’s War & Sanctions project has identified foreign-origin components at the site, including machinery from Taiwan, South Korea, and Switzerland.
