According to Ukrinform, ATESH reported this on Telegram.

The plant is involved in the full production cycle of Molniya combat and reconnaissance UAVs, the manufacture of components for Orion systems, and the development of control systems for mass-produced FPV drones.

The damage to the substation disrupted the stable operation of Atlant-Aero’s production lines. Without a reliable power supply, the plant cannot continue to manufacture unmanned systems or electronics for new batches of drones for Russian troops.

The power outage led to an emergency shutdown of the production process. The outage disrupted the current cycle of product assembly and testing, temporarily halting operations in the plant’s key workshops.

As reported by Ukrinform, ATESH agents destroyed telecommunications equipment on communication towers in the Belgorod region of the Russian Federation, which had been transmitting data on air raids.
