New information has emerged about the successful attack.
On the night of October 3, 2026, in Kaluga (Russia) a series of explosions rocked the city amid a drone attack. It later emerged that the target of the attack was the company JSC “Voskhod,” also known as the Kaluga Radio Tube Plant, which manufactures electronic components for the Russian military-industrial complex. The OSINT project Supernova+ reported that the facility may have been hit.
Judging by video footage that has surfaced online and testimonies from local residents cited by Supernova+, a fire broke out on the plant’s premises. However, it is not yet possible to independently determine the extent of the damage to the plant. There is also no confirmed information about which specific part of the facility may have been damaged.
Incidentally, judging by the video, cruise missiles or Ukrainian jet-powered drones may have been used to strike the facility, as the characteristic sound of their operation can be clearly heard immediately before the explosions. However, as of this publication, there has been no official confirmation from the Ukrainian command regarding this operation.
What is known about the nighttime attack on Kaluga
On the morning of October 3, Russian sources reported a drone attack on the Kaluga Region.
The region’s governor, Vladislav Shapsh, stated on his Telegram channel that Russian air defense forces allegedly shot down 13 UAVs over Kaluga, as well as over Zhukovsky, Iznoskovsky and Maloyaroslavets municipal districts.
According to him, apartment buildings in Kaluga were damaged as a result of the attack. Earlier reports also mentioned people who sustained minor injuries from flying glass shards. Hospitalization, according to the governor, was not required.
The Russian Ministry of Defense subsequently announced that a total of 218 Ukrainian drones had been destroyed over Russian territory and the occupied territories on the night of October 3.
Which facility could have been the target
Amid the nighttime attack, claims emerged online that one of the possible targets could have been the Kaluga Radio Tube Plant, a facility belonging to the Russian military-industrial complex, which currently operates as JSC “Voskhod.”
According to the Ukrainian government portal “War and Sanctions,” operated by the Main Intelligence Directorate of the Ukrainian Ministry of Defense, the “Voskhod” plant is not merely an industrial facility but a key manufacturer of high-precision microelectronics for Russian weapons. More than 90% of the plant’s total output is supplied directly to meet the needs of the Russian Armed Forces.
The plant manufactures electronic components without which Russian missiles simply cannot fly:
For the Kh-101 cruise missiles: the plant supplies operational amplifiers for the computing units and analog switches that are part of the missile’s electronic subsystems.
For the “Iskander-K” missiles: the plant manufactures the main transmitters for the “Zarya-61M” onboard computer, as well as components for the GIB-123-4 inertial navigation system.
For the Iskander-M ballistic missile: “Voskhod” manufactures specialized RUD20 integrated circuits.
In addition, the plant provides maintenance services for armored vehicles: it manufactures systems for the chemical cleaning of T-72 tank gun barrels and devices for testing generators on the BMP-2 and BMP-3. The company also supplies equipment for the mechanical securing of fuses for artillery munitions of various calibers.
In addition, Kaluga is home to JSC “Typhoon”—a defense industry enterprise specializing, in particular, in the production of radar and radio equipment.
Gaps in International Sanctions
Ukraine imposed sanctions against “Voskhod” pursuant to Decree No. 227/2023 of April 15, 2023, for a period of ten years. Despite this, the company is still not included on the sanctions lists of the United States, the European Union, or the United Kingdom. Overall, nearly half of the 155 companies belonging to the Russian holding company “Roselektronika” continue to operate without Western restrictions.
Thus, such strikes by the Defense Forces are currently the most effective way to halt the production line of the Russian military-industrial complex.
