Russian tech giant Yandex's data center in Sasovo burned out from the inside, a Ukrainian OSINT analyst wrote on 22 October. On cloud-free satellite images, he saw almost no significant holes in its roof. Ukrainian drones hit the site overnight on 8 October.

Sasovo was the first strike on a data center in Russia. It came two weeks after Russia destroyed data centers in Kyiv. Drones then hit Yandex sites in Vladimir and Kaluga, a Sber data center, and a VK data center near St. Petersburg, which VK acknowledged. In occupied Donbas, monitoring channels reported hits on buildings housing telecom operators.

What the analyst sees

The analyst, who goes by Harbuz, runs the Ukrainian OSINT channel Dnipro Osint. His roof reading comes from the images. His interior claim comes from what he called available information: he wrote that a fire broke out inside and put part of the equipment out of action.

In an earlier post, Harbuz wrote that a third of the data center had burned out. In the new one, he writes that the building burned out from the inside. He does not say whether he revised the earlier figure.

Russian outlet Agentstvo studied Airbus images from 12 October. It found damage on about a third of the building. Unlike Harbuz, though, Agentstvo described a blackened western roof with damage resembling holes.

What Yandex says

On 8 October, Yandex stated that the attack caused a fire and forced it to suspend operations at the site, which hosts tens of thousands of servers, Reuters reported. Yandex Cloud and the Disk and Documents services that run on it ran with major disruptions that morning, Russian outlet The Bell reported.

Later that day, the company stated: "The scale of the damage to the infrastructure is still being assessed. For the moment, we cannot confirm whether it is possible to restore the data centre equipment in Sasovo." Two of Yandex's three supercomputers, used to develop its AI model, are housed there.

The same day, journalists asked Ukrainian President Volodymyr Zelenskyy whether Ukraine was targeting Russian data centers. He did not refer specifically to the Yandex strike, Reuters noted, but said: "We always respond in mirror-like fashion."

An explosion hit the 75th Arsenal, a Russian army plant in Serpukhov south of Moscow, overnight on 22 October, Russian Telegram channel Astra reported. Russian officials also claimed drone attacks on the Moscow region, Tula, and Lipetsk that night.

As Russia presses its full-scale invasion, Ukraine’s long-range drones and missiles keep hitting military plants and refineries deep inside Russia. Ukrainian outlet Militarnyi says this plant specializes in repairing Buk and S-300 air defense systems. Astra describes it more broadly, as making weapons and ammunition and repairing military equipment. If Militarnyi is right, the blast hit a site that fixes Russian air defenses. It came the night Moscow’s mayor credited air defenses with stopping hundreds of drones.

Blast at the arsenal

An Astra OSINT analyst placed the explosion inside the site from a video, the channel said. Residents claimed in local chats that blasts followed passing drones, then at least three missiles. Astra did not confirm the missile count. Serpukhov lies about 99 km south of Moscow. Ukraine has sanctioned the plant, and the US Treasury has listed it too. As of the morning of 22 October, no Russian official had confirmed the blast.

630 drones, by Moscow’s count

Moscow Mayor Sergei Sobyanin claimed that 630 drones flew toward the Moscow region from 20:30 on 21 October to 04:00 on 22 October. He claimed most were destroyed far out and 163 were neutralized on approach to Moscow. Two people were injured in Voronovo, in New Moscow, he stated.

Tula Oblast Governor Dmitry Milyaev claimed air defenses downed 70 Ukrainian drones over his region. Private homes were damaged in Tula and the Zaoksky district, he stated.

Lipetsk governor claims homes and a clinic damaged

Earlier in the night, Ukrainian monitoring channel Exilenova+ posted footage of commotion in Lipetsk after explosions. Lipetsk Oblast Governor Igor Artamonov claimed a drone strike damaged homes, apartment blocks, and a closed polyclinic. A man born in 2001 was injured and hospitalized, Artamonov claimed.

In May, Ukrainian intelligence said Russia was deploying more regiments against strike drones. In September, Ukrainian units hit more Russian air defense systems and radars than in any month since 2024, Ukraine’s Defense Ministry said. Analyst Oleksandr Kovalenko counted 76 destroyed in September with days of the month still to go and argued Russia cannot replace such losses. If Militarnyi’s description holds, losing repair capacity would deepen that gap.

Ukraine’s military intelligence (HUR) published a 3D model and parts list of Russia’s new Filin cruise missile on 22 October. The breakdown names the Russian companies behind the missile and the foreign makers of its electronics.

HUR runs its War&Sanctions portal to trace such parts back to their makers. Its stated aim is to “deprive the aggressors of the ability to produce weapons for terror,” the portal says. Meanwhile, Russia is betting on cheap, fast cruise missiles, Serhii Beskrestnov, a freelance adviser to the president on technology, told Radio NV in mid-September. Naming the Banderol, Dan-T, Dan-M, and Gerbera-5, he warned they would soon outrun Ukraine’s jet-powered interceptors, so Ukraine needed its own cheap missiles to shoot them down.

Composite body, ground launch

JSC NPO Molniya, part of Russia’s Tactical Missiles Corporation, builds the Filin, HUR said. The agency called it part of a Russian defense-industry trend toward cheap jet-powered, ground-launched air-attack weapons. Russia began firing it at Ukraine in late summer 2026.

HUR’s data puts the carbon and fiberglass fuselage at 3.5 m, with a 3 m wingspan. Some parts are 3D-printed. Russia claims a top speed of 800 km/h. The range is 600–1,200 km, and the missile flies at ultra-low altitude or up to 6 km. Versions carry 50-kg or 100-kg warheads. A solid-fuel booster fires it from a ground launcher.

A firm tied to a Shahed-type drone

PLAZ LLC makes the onboard equipment, HUR said. The firm also helps produce the Garpiya, a version of Russia’s Shahed-type Geran-2 drone. Filin and Garpiya units share a similar layout and markings. Guidance combines a Chinese-made inertial navigation system with a 16-channel Kometa anti-jamming module from Russia’s VNIIR-Progress.

The electronics resemble those in other Russian missiles and drones but carry a larger share of Chinese parts. Of 81 components, 35 are American and 22 Chinese. The engine, however, is Russian: an R500 turbojet from Reynolds LLC. A similar engine earlier turned up in the S-71K Kover aviation cruise missile and S-71M Monokhrom, HUR said.

For comparison, Ukraine found more than 20 foreign components in a different cheap missile, the Banderol, in May 2025. They included 10 US microchips, and the Banderol flies on a Chinese jet engine.

Russian missiles and drones killed one person and injured 24 in Kyiv overnight on 22 October, the Kyiv City Prosecutor’s Office said. Damage spread across six of the city’s districts, the city military administration reported.

The strike came hours after Kremlin aide Yuri Ushakov said Putin had told Witkoff that Russia was “in principle” ready to resume three-way talks with the US and Ukraine in mid-November. President Volodymyr Zelenskyy read the overnight attack as a sign that Russia’s attitude has not changed. A day earlier, Russian drones killed two people in a 24-story Kyiv apartment block.

21 ballistic missiles in three waves

Russia fired 21 ballistic missiles at Kyiv overnight, Zelenskyy said. The barrage came in three waves, around 22:00, at about 02:00, and around 03:30.

Across Ukraine, air defenses downed or suppressed 181 of 210 Russian drones, the Air Force said. Its report did not mention any ballistic missiles shot down.

One killed in the Dniprovskyi district

The only death in Kyiv came in the Dniprovskyi district, on the city’s left bank. There, Russian strikes destroyed 13 detached houses on several streets, prosecutors said. Police said the man killed was 48 and that six people were injured in the district, four of them children, the youngest aged five.

Of the injured, five are minors and two are young children, and prosecutors reported acute stress reactions among them. A 16-year-old boy is in hospital with a closed head injury, prosecutors said. Sixteen of the injured were hospitalized, the city military administration said. The final number of injured is still being established.

Ambulance station and monastery damaged

In the Holosiivskyi, Obolonskyi, Pecherskyi, and Sviatoshynskyi districts, the attack damaged eight apartment buildings, prosecutors said. It also damaged a building-supply hypermarket, a restaurant, a monastery building, a post office, and office premises.

In Pecherskyi, Russia damaged an ambulance station and six ambulances, Kyiv Mayor Vitali Klitschko wrote. The State Emergency Service said eight people were injured in that district, three of them children, and reported damaged transport infrastructure in the Darnytskyi district.

Bridge closed, metro line split

The strikes damaged metro infrastructure on the Pivdennyi (Southern) Bridge, Kyiv Metro said. As of the morning, green-line trains ran in two sections, Syrets–Vydubychi and Osokorky–Chervonyi Khutir. Inspections and repairs would continue after the all-clear, the metro said.

Oleksii Biloshytskyi, head of Ukraine’s Patrol Police Department, announced that traffic across the bridge toward the left bank was temporarily closed. The city is adding buses on routes 22 and 91, the city administration said. Russian drones had already hit the bridge repeatedly in early October.

Denmark will guarantee a loan to the Danish subsidiary of Fire Point, the Ukrainian maker of Flamingo cruise missiles, the Danish Business Ministry announced on 21 October. The financing will run through EIFO, Denmark’s state export and investment fund.

Ukraine uses its Flamingo missiles to strike defense plants deep inside Russia as Moscow continues its full-scale invasion. Fire Point broke ground in December 2025 on a plant in Vojens, southern Denmark, to make solid fuel for the missiles. The project has since grown far more expensive. In August, CEO Iryna Terekh said its estimated cost had risen from €50 million to above €150 million, calling the figure “very rough.” The war, meanwhile, stands in the way of Fire Point borrowing on ordinary terms in Denmark, the ministry said. That is why the Danish state is guaranteeing the loan.

What Denmark is putting up

The guarantee covers 750 million Danish kroner, or about $112.6 million, Reuters reported. Terekh said in August that the plant’s launch had slipped to late 2027. The ministry called the deal another big step toward starting production. However, Ukrainian outlet Defender Media noted that the statement does not say directly that the loan will fund the plant.

EIFO chief Peder Lundquist said the fund is involved in nearly 40 projects linked to Ukraine. Business Minister Martin Lidegaard said hosting a Ukrainian defense company brings Denmark knowledge, production, and partnerships. Europe’s security and freedom, he added, start in Ukraine.

Better shielded from Russian strikes

Defense Minister Jeppe Bruus said Denmark was the first country to decide to let a Ukrainian defense company set up on its soil. Production outside Ukraine, he argued, is better protected from Russian attacks. He added that Fire Point’s presence opens cooperation that could give Denmark access to technologies developed in wartime.

Denmark first said in September 2025 that Fire Point would make long-range missile fuel on Danish soil. Since then, the company has signed deals with more than a dozen European firms for FREYJA, an anti-ballistic project. It could reduce Europe’s long-term reliance on scarce US-made Patriot interceptors. Fire Point aims for a first ballistic missile intercept with it by mid-2027.

Poland has paused the delivery of a large military aid package to Ukraine after a Lviv regional council honored the Ukrainian Insurgent Army (UPA), a WWII nationalist force, a source in the Ukrainian government told European Pravda on 21 October. A Polish Defense Ministry spokesperson told Fakt the report was untrue, though he told WP he knew nothing about a possible delay in shipment.

If confirmed, the freeze would carry a history dispute into Poland’s military aid. The row flared in May, when Kyiv named a special forces unit after the UPA, and in June Poland’s president stripped Zelenskyy of Poland’s highest honor. Even so, Ukraine’s ambassador said in August that Polish military aid was still flowing.

A vote and a disputed freeze

The Lviv Oblast Council voted on 20 October to name 2027 the year of the UPA, its commander Roman Shukhevych, and nationalist activist Oleh Olzhych. The UPA fought Nazi Germany and the Soviet Union, but Poland holds it responsible for mass killings of Poles in Volhynia and Eastern Galicia in 1943–1944. The resolution disappeared from the council’s website late that evening, RMF24 reported.

The source blamed what it called the councilors’ irresponsible actions, saying the vote came as Poland prepared the shipment and that work through closed channels is underway. The ministry spokesperson, Janusz Sejmej, called the report untrue. Asked whether it could reflect a delay in shipment, he said he knew nothing about that.

Polish officials push back

On 20 October, Defense Minister Władysław Kosiniak-Kamysz wrote that Ukraine’s authorities must distance themselves from the council’s position.

The next morning, Prime Minister Donald Tusk called the vote unwise and harmful above all to Ukraine. He said he had warned Zelenskyy earlier that such gestures hinder Ukraine’s friends, though the president was not responsible for this vote. At such moments, Tusk said, Russians always rub their hands.

Foreign Minister Radosław Sikorski then requested that councilor Sviatoslav Sheremeta, who proposed the resolution, be added to Poland’s list of unwanted persons. That afternoon, Interior Minister Marcin Kierwiński said the decision had been made. Sheremeta is barred from the Schengen zone until 2031, RMF24 reported. Poland had already barred him once, in 2017, the outlet said.

Kyiv asks for restraint

Earlier on 21 October, before the ban, Ukraine’s Foreign Ministry called the vote counterproductive in a reply to journalists and urged Warsaw to avoid abrupt steps. Zelenskyy’s closest aides had also promised the resolution would not take effect, Deputy Foreign Minister Marcin Bosacki told TVN24.

Investors who buy idle sanctioned tankers and refit them could put the ships back into legal oil trade, US Energy Secretary Chris Wright said on 19 October, Bloomberg reported. He laid out the plan five days after a US official described it to Reuters.

That official said the aim was to cut record tanker freight rates. The Energy Department added that any relief would not help Russia move its oil. The plan comes weeks before the 3 November midterms, with voters worried about fuel costs after gasoline and diesel prices surged in the Mideast conflict. Yet the shadow fleet is also how Russia sells oil past sanctions, and those sales fund its war against Ukraine. In December 2025, Ukraine’s foreign intelligence counted more than 1,100 tankers serving Russia alone, 226 of them under US sanctions.

An approval process Wright didn’t detail

Many sanctioned tankers sit idle, Wright told Bloomberg’s Annmarie Hordern, and buyers keep approaching the administration offering to fix them up and carry only legal oil.

“We’re going to move some of the ships from what I call the ‘bad-guy fleet’ to the ‘good-guy fleet,’” he said. “They will not carry sanctioned oil anymore.”

The ships must go through an approval process, Wright said, but he gave no criteria. He insisted “there is no removing of sanctions.”

He put the global dark fleet at about 1,600 ships, a count covering vessels that hauled Venezuelan, Iranian, and Russian oil. Dozens or even hundreds could turn legitimate, he said. The ships are no longer needed for Venezuelan oil, Wright said, and no Iranian oil is moving. Russian oil exports, he added, “are certainly not growing.”

Diesel, a waiver, and the tankers

Earlier, on 9 October, the Treasury issued General License 135, allowing some deals in Russian diesel until 7 April 2027. On 16 October, US President Donald Trump waived sanctions and tariffs under the Graham Act, leaving earlier sanctions intact. That law had directed him to review and sanction shadow-fleet vessels. Trump defended the waiver as a way to keep Moscow at the negotiating table.

House Speaker Mike Johnson told Fox News host Larry Kudlow on 18 October that he had asked the White House team to “carefully consider the unintended consequences,” The Hill reported. He added that he thought “the right decision will be made” in the end.

In a direct confrontation with Russia, European NATO states would likely be even more vulnerable than Ukraine to swarms of Russia’s new jet-powered strike weapons, Fabian Hoffmann of the Norwegian Institute for Defence Studies (NIDS) argued in a 20 October op-ed for the Center for European Policy Analysis (CEPA). He calls them low-cost cruise missiles. Just three days earlier, Romania met what it believes were two of them over the Black Sea.

Romanian F-16 fighter jets shot down two jet-powered Geran-family drones over Romania’s territorial waters on 17 October, the Defense Ministry said. Interim Defense Minister Radu Miruță said they flew at about 450 km/h and were likely Geran-4s, the first of that type Romania had downed.

Faster drones for a faster war

Russia began using the Geran-4 in May in response to effective Ukrainian interceptor drones, Ukraine’s military intelligence (HUR) said, adding that it reaches up to 500 km/h. By June, those interceptors were downing about half of slower Shahed-type drones, defense adviser Serhii Beskrestnov estimated.

Hoffmann traces the shift to the Geran-3, a model Ukraine recovered intact in 2025. In his account, a Chinese JT80 turbojet roughly doubled its speed, from 185 to 350 km/h. However, he puts newer models, including the Geran-4, at 600 km/h or more, above HUR’s figure for that model.

By his estimate, each costs $150,000–$250,000, against about $50,000 for a long-range drone. Still, from Russia’s perspective, he wrote, that buys a significantly higher chance of getting through.

Engines are the bottleneck

Hoffmann argues defenses must match the threat’s speed, for example with jet-powered interceptor drones. Ukraine already fields some. On 4 October, President Zelenskyy said its Bars interceptors had shown the highest percentage among Ukrainian interceptors, about 30% of targets, according to Militarnyi. One unit destroyed five aerial targets with five Bars interceptors, Defense Minister Yevhenii Khmara later told journalists. He also called aviation one of the most effective tools against jet drones.

Hoffmann’s concern is scale. Jet engines are in short supply, he wrote, because too few European and US suppliers can meet demand. Ukraine’s Defense Industry Council flagged a shortage of such engines for its drones in April. In his view, gun systems and higher-end missile defenses are too scarce or too costly to fill the gap.
