Ukrainian forces appear to have struck a Russian military repair facility near its capital city of Moscow during a massive overnight drone offensive.
The strikes involved hundreds of uncrewed aircraft launched toward Moscow and other regions across Russia.

The strikes began on the evening of Wednesday, October 21, and continued into Thursday morning.
Reports described explosions and a large fire at the 75th Arsenal military facility located in Serpukhov, south of Moscow.
Reports also described eyewitness footage, which was analyzed by independent Russian media outlet Astra, that indicates the Russian Defense Ministry facility was indeed among Ukraine’s targets.
The site is valuable to the Russian military, as it repairs and maintains military equipment, including the Buk and S-300V air defense systems used to defend Russian infrastructure.
The attack was part of a much larger offensive that has been gradually escalating since at least the summer.
This overnight strike, however, reportedly involved more than 800 Ukrainian drones, and it came only hours after Russian President Vladimir Putin agreed in principle to resume U.S.-mediated talks with Ukraine.
Explosions at the 75th Arsenal
The reported strike on the 75th Arsenal occurred in the early hours of the morning of October 22. Residents of Serpukhov reported hearing explosions and witnessing a fire near the facility.
Video footage analyzed by Astra and shared by nearby eyewitnesses identified the location as a facility operated by Russia’s Main Missile and Artillery Directorate (GRAU).
Residents said that they saw at least three missiles strike the general area, though the accounts have not been independently verified.
Another report, this time from Southern Courier, a regional Ukrainian news outlet, described a series of impacts at the site that triggered a large fire, and said air raid alerts and warnings of incoming drones continued for over six hours.
The exact damage to the facility, however, remains unclear.
There has been no confirmation of what buildings were struck or if any military equipment was destroyed.
Ukrainian monitoring channel Exilenova+, however, suggested that the strike may have used a combination of missiles and jet-powered drones.
Still, the weapons used have also not been officially confirmed.
The 75th Arsenal Matters to Russia
The 75th Arsenal is a key target because it houses some of Russia’s most critical air defense equipment.
Russian state-owned defense conglomerate Rostec says the facility has repaired Buk-M1 and Buk-M2 surface-to-air missile systems, as well as components for the larger S-300V systems.
The U.S. Treasury Department recognizes the company as a military contractor responsible for overhauling everything from radar stations and ground-based identification equipment to air defense systems.
Damaging a site like this could theoretically hinder Russia’s ability to repair damaged air defense systems, making it harder to defend some of its most critical infrastructure.
Sustained strikes on sites like these, especially successful strikes that turn off existing air defense infrastructure, could seriously affect Russia’s ability to defend itself and, therefore, change Moscow’s calculations when launching new long-range strikes.
Russia Says More Than 800 Drones Intercepted
The strike was part of a much larger overnight assault.
Moscow Mayor Sergei Sobyanin claimed that 630 Ukrainian drones were tracked heading toward the Moscow region late on October 21 and in the early hours of October 22.
The mayor said that Russian defenses intercepted most of the projectiles far from the capital, while another 163 were destroyed as they approached Moscow city.
The Russian Ministry of Defense then claimed that 808 Ukrainian drones were shot down across the country and in occupied Crimea overnight, though the figures have not been independently verified.
The scale of the attack led Moscow’s major airports to restrict flights temporarily.
Russian authorities also reported injuries and damage in several regions throughout the country.
“During the past night from 20.00 on October 21 to 8.00 on October 22, the air defense forces on duty destroyed 808 Ukrainian aircraft-type unmanned aerial vehicles,” the Defense Ministry confirmed in a statement.
The statement also said the drones were shot down over Belgorod, Bryansk, Vladimir, Voronezh, Kaluga, Kursk, Leningrad, Lipetsk, Orel, Rostov, Smolensk, Ryazan, Yaroslavl, Tula, Tambov, and Tver regions, the Black Sea, and the Republic of Crimea.
Residential Buildings and Infrastructure Hit
The overnight strikes also saw damage to civilian infrastructure across multiple Russian regions.
The Kyiv Post also reported that Lipetsk Governor Igor Artamonov confirmed one man was injured. Residential buildings and Polyclinic No. 7 also sustained damage.
In Tula, Governor Dmitry Milyaev reported damage to private homes but confirmed there were no casualties. Residential properties and electricity infrastructure were also reportedly damaged in Voronezh.
