Ukrainian Security Service long-range drones struck the Signal plant in Russian Stavropol on 26 July, targeting one of Russia’s largest radio electronics manufacturers, hromadske reported, citing a source in the Security Forces.

One of the strikes reportedly hit building No. 2 (workshop No. 5), where” expensive imported equipment is located — machine tools based on numerical program control,” the source told hromadske.

The second strike was recorded in building No. 1, which houses workshop No. 17 for radio electronic devices.

The Signal plant specializes in producing various types of electronic warfare systems, radar, radio navigation equipment, and remote control radio equipment for Russia’s military-industrial complex. The facility operates under international sanctions.

The targeted workshops house critical infrastructure for military production: from imported machinery with numerical program control systems to radio electronic devices essential for military communications and navigation systems.

Russia’s Defense Ministry reported intercepting 54 unmanned aircraft overnight on 26 July across five oblasts, as well as over temporarily occupied Crimea and the Azov and Black Seas. By morning, Russian forces claimed to have downed six additional drones over North Ossetia and Moscow Oblast.

The attack represents a significant strike on Russia’s defense manufacturing capabilities, targeting a facility that produces electronic warfare equipment and radar systems used by Russian forces.
