Drone Strike Hits Russia’s Signal Plant—Home of Key Electronic Warfare Systems

On the morning of July 26, drones struck an industrial facility in the Russian city of Stavropol, with multiple reports identifying the target as the “Signal” defense plant—one of Russia’s key manufacturers of electronic warfare systems.

According to regional authorities and footage shared by local Telegram channels, several drones reached industrial areas of the city around 5 a.m., causing loud explosions and a brief fire at the site.

Governor Vladimir Vladimirov confirmed the incident, noting that the fire was promptly extinguished and no casualties were reported in Stavropol itself. Civilian infrastructure reportedly remained unaffected.

Open-source images suggest the primary strike hit the main building of the Signal plant. While structural damage appears limited, the explosion may have impacted internal equipment used in the plant’s production lines.

The Signal plant, founded in 1971 and integrated into Russia’s state-owned defense conglomerate Rostec in 2012, specializes in the production of electronic warfare systems for aircraft, naval, and ground platforms.

These include systems such as “Topol-E,” “Smalta,” and “Gardenia.” The facility also produces equipment designed to protect against electrochemical corrosion.

Despite being sanctioned by the EU, US, Ukraine, and Japan since 2022, the plant has continued operations—reportedly sourcing components through alternative supply chains, including Chinese-manufactured parts.

Stavropol lies approximately 350 to 380 kilometers from the nearest Ukrainian-controlled territory, placing it within range of certain long-range UAVs recently employed by Ukrainian forces.

Earlier, drones struck the Nevinnomyssky Azot chemical plant in Stavropol, a key supplier of explosive precursors for Russian bomb factories. The facility produces nitric acid and ammonium nitrate used in artillery shells and air-dropped munitions. Analysts say the attack may have targeted volatile areas linked to military-grade explosives production.
