Ukraine's Unmanned Systems Forces attacked the Rezonit Technopark in Russia's Moscow Oblast overnight on June 12, with explosions reported at the facility, the Ukrainian military said.
The operation was designed to "reduce Russia's ability to produce high-tech weapons and equipment," as the facility assembles circuit boards and electronics for the Russian military-industrial complex, the General Staff of Ukraine's Armed Forces said.
The consequences of the attack are being clarified, according to the statement.
"The Rezonit plant in the Zubovo technopark... is a juicy target, located roughly 40 kilometers (25 miles) from Moscow's center," Ukrainian National Security and Defense Council official Andrii Kovalenko said.
According to Kovalenko, the circuit boards manufactured at Rezonit are used for flight control and navigation in Iskander, Kalibr, and Kh-101 missiles, as well as Orlan and Lancet drones and other systems.
Ukrainian Telegram channel Supernova+ published alleged footage of an explosion in Zubovo, with drones audible in the background. The strike tore a hole in the plant's roof, the channel wrote.
Russia's Defense Ministry claimed its forces shot down 52 Ukrainian drones overnight, including three over Moscow Oblast. Russian officials have not yet commented on a possible attack against the technopark.
Zubovo is located around 500 kilometers (300 miles) north of the Russia-Ukraine border.
Ukraine has repeatedly deployed long-range drones to target Russian military and industrial facilities deep in the rear, aiming to disrupt Moscow's ability to wage its all-out war.
In one of the most daring operations, the Security Service of Ukraine (SBU) attacked four Russian air bases on June 1, allegedly hitting 41 Russian bombers and other aircraft.
