Militarnyi reported that following Ukraine’s operation Spiderweb that targeted Russian strategic bombers at five bases, Russia was forced to redeploy key elements of its strategic aviation fleet to airbases in the Far East, complicating its ability to launch missile strikes on Ukrainian territory.

According to OSINT sources, including the Tracking Telegram channel, two Tu-160 bombers previously based at Belaya airbase were relocated to the Anadyr airfield. An additional five Tu-160s were moved to Yelizovo airbase. These facilities are located 6,770 km and 7,250 km from Ukraine respectively.

Meanwhile, Tu-22M3 bombers based at Olenya are periodically transferred to Sovetsky airfield in the Komi Republic, approximately 2,400 km from Ukrainian borders. Tu-95MS aircraft now operate between Olenya, Engels-2, and Ukrainka airbases.

For launching Kh-101 cruise missiles, Tu-95MS bombers stationed at Ukrainka must fly at least 7,000 km to reach launch areas near Saratov Oblast, and then return another 5,400 km. This creates a 12,400 km mission round trip, lasting up to 23 hours in the air.

Operational impact and aviation strain

Russia’s dispersal of its strategic bombers aims to reduce vulnerability by spreading aircraft across remote airbases. However, this has introduced significant complications, including excessive flight time, accelerated wear of aging airframes, heightened crew fatigue, and increased maintenance costs, Militarnyi notes. The added distance also increases the likelihood of technical failure or human error, raising the risk of crashes.

The strain on Russian aviation logistics could in the long run reduce the frequency of air-launched cruise missile strikes on Ukraine.

SBU’s Operation Pavutyna

On 1 June 2025, the Security Service of Ukraine (SBU) launched Operation Pavutyna (“Spiderweb”), a large-scale special operation targeting Russia’s strategic bombers. The targets included Belaya, Ivanovo, Ukrainka, Olenya, and Dyagilevo airbases.

Militarnyi says preliminary assessments indicate that at least 8 Tu-95MS (or Tu-95MSM), 12 Tu-22M3, 2 A-50 early warning aircraft, 1 An-12 transport plane, and possibly 1 Il-78M tanker were hit by Ukrainian drone strikes.

Though a full set of satellite images has not yet been published. Notably, the strike on one Tu-95MS seen in satellite imagery is not included in the videos.

“In addition, the video footage released by the SBU is incomplete: it does not show the damage to one of the Tu-95MS aircraft, which is visible in satellite images,” Militarnyi wrote.

A former head of one of the key departments in the Logistics Forces of Ukraine's Armed Forces is suspected of illicit enrichment worth Hr 12 million ($290,000) and illegal possession of weapons, the State Investigation Bureau (DBR) and the National Agency on Corruption Prevention announced on June 9.

Ukraine's military has seen several corruption scandals since the start of Russia's full-scale war, related to illicit enrichment, money laundering, bribery, and misconduct of the command.

The agencies did not disclose the suspect's name, who faces up to 10 years in prison if convicted.

During 2023-2024, the ex-head of the department purchased 14 land plots in Kyiv Oblast, an apartment, a Toyota Tundra, a Skoda Octavia, a Hyundai Tucson, and domestic government bonds issued by Ukraine's Finance Ministry, according to the National Agency on Corruption Prevention.

Meanwhile, the suspect and his family had no financial means to purchase these assets, the agency's statement reads.

While searching the suspect's house, law enforcement officers also found weapons and ammunition stored illegally.

The preventative measures for the suspect are now being considered.

Ukraine's Logistics Forces, established in 2018, are in charge of providing supplies and technical maintenance for the Ukrainian troops on the front line. This branch of the armed forces is also responsible for adapting the Ukrainian army to NATO standards, particularly in the field of logistics.

Exclusive: Ukraine could face 500+ Russian drones a night as Kremlin builds new launch sites

Russia will soon be able to deploy more than 500 long-range drones a night to attack Ukraine as it ramps up production and builds new launch sites for them, a source in Ukraine’s military intelligence (HUR) has told the Kyiv Independent. According to the source, Russia’s production rate for one

Ukrainian drones will reach a new level. Newly appointed commander of the unmanned systems forces, Robert “Madiar” Brovdy, launches a major upgrade and deployment, Texty reports. 

Brovdy says 6–7 units of the Unmanned Systems Forces’ Drone Line are expected to enter the top ten most effective UAV units in the current ranking of the Armed Forces of Ukraine.

Over the next 100 days, Brovdy also announced the following steps:

• Deployment of a unified electronic system for planning, coordination, command, and online reporting for all USF units, 
• Expansion of USF operations into tactical and operational depth with 12 levels of application — from reconnaissance to countering enemy drones, 
• Increase in domestic production of munitions and creation of a unified supply depot for critical components such as StarLink, batteries, EW systems, and FPV parts, 
• Use of ground robotic complexes for the logistics of munitions, drones, and peripherals, 
• Execution of a unified recruitment campaign and establishment of a proprietary training network for drone pilots and operators of various systems, 
• Separate re-certification of personnel, retraining of inexperienced or unfit crews, and retraining by types of flight activities. Command aims for a clear match between functions, training, and the combat potential of each fighter.

As part of the reform of the Unmanned Systems Forces, a unified approach is planned to analyze capabilities, operational facts, and effectiveness of actions according to drone models and types of ammunition. This will form the basis for precise planning and efficient real-time supply of units.

A separate direction, details of which are not disclosed, concerns the use of UAVs at strategic depth.

In the field of technology development, the current Innovation and Development Center is undergoing transformation. Instead of functioning at the brigade level, it will serve the needs of the entire branch of the armed forces.

Russian forces have captured the village of Kostiantynivka in northern Sumy Oblast — not to be confused with the strategic town of the same name in Donetsk Oblast — and are intensifying multi-axis assaults toward Sumy City, according to Ukrainian and Western sources.

Expanding the northern frontline

According to the Institute for the Study of War (ISW) on 2 June, Russian troops are attempting to widen the northern Sumy Oblast frontline via three axes north and northeast of Sumy City. Geolocated footage confirmed recent Russian movements near Andriivka and Yablunivka. Russian milbloggers claimed that Oleksiivka, Novomykhailivka, and Kindrativka had been seized, with troops pushing into northern Andriivka, west of Yablunivka, and toward Kostyantynivka.

Elements of Russia’s 18th Motorized Rifle Division and 177th Naval Infantry Regiment are reportedly operating in the area, alongside airborne regiments from the 76th VDV Division. Military observer Kostyantyn Mashovets noted that the 752nd Regiment and 200th Brigade were recently redeployed from Lyman and Chasiv Yar to bolster forces in Sumy Oblast.

Russia’s strategic goals near Sumy

ISW notes that Moscow aims to approach the Khotin-Khrapivshchyna line, roughly 12–15 km from Sumy, placing the city within tube artillery range. The reported use of drones and artillery strikes is likely part of preparations for a potential offensive on Sumy City. However, ISW assesses that Russian forces are unlikely to capture the city in the near term.

DeepState and Suspilne confirm ground situation

Citing analysts of the Ukrainian group Deep State, monitoring the frontline situation, Suspilne reported that Russian forces occupied Volodymyrivka and Kostiantynivka and made advances in Oleksiivka, with portions still in a grey zone. Ukrainian Border Guard Service spokesman Andrii Demchenko identified Yunakivka and Khotin as key targets. He warned that if Russian forces manage to move artillery closer, threats to Sumy will intensify.

Military expert Pavlo Narozhny told Suspilne that the push toward Yunakivka aims to cut off Ukrainian supply lines from the Sumy-Yunakivka-Sudzha highway, which supports troops on the border and in Russia’s Kursk Oblast. Narozhny said Yunakivka offers intact infrastructure suitable for Russian consolidation and future advances.

Ukrainian positions under pressure from Russian “meat-wave assaults”

Fighting continues near Bilovody and Loknya, with attempted incursions into Yablunivka. Deep State co-founder Ruslan Mykula told Suspilne Russian forces were repelled in some villages but remain focused on isolating Yunakivka from the west.

Narozhny also described earlier attempts to sever logistics using drones near Novenke and claimed Russian forces now push through small villages like Volodymyrivka. He emphasized that their main objective remains Yunakivka, a staging ground for further operations toward Sumy.

A combat medic anonymously told Suspilne that enemy drone and equipment superiority complicates evacuations and supply runs. A frontline sergeant described Russia’s tactic as “meat assaults,” sending successive small units using motorcycles and ATVs. Survivors regroup and continue advancing through tree lines and villages.

Threat level and troop presence

Narozhny estimated around 60,000 Russian troops are now deployed along the border, posing a significant but not yet critical threat. He said Ukraine must maintain 20,000–30,000 troops in the area due to the length of the frontline.

Former intelligence chief Mykola Malomuzh stated that the current Russian grouping had earlier pushed Ukrainians from Kursk Oblast and now aims to secure new positions for potential strikes on Sumy. He said the “buffer zone” narrative masks broader offensive ambitions. Ukrainian defenses are reportedly holding due to well-fortified positions developed over time.

Narozhny also pointed to the forest between Yunakivka and Sumy as a major obstacle. He compared it to the Serebryanskyi forest in Luhansk Oblast, where Russian troops remain stalled after two years.

Territory under Russian control

As of 2 June, Russian troops controlled around 125 square kilometers of northern Sumy Oblast, with another 70 km² in the grey zone, according to Deep State. Villages under Russian control also include Novenke, Basivka, Veselivka, and Zhuravka.

Overnight on 3 June, DeepState reported that Russian forces had captured Kostiantynivka in Sumy Oblast. The status of Kindrativka, Vodolaha, and Oleksiivka remains under clarification. DeepState noted that “the situation continues to deteriorate due to constant enemy pressure and large infantry numbers,” adding that “after targeting enemy concentrations, new waves rush in so fast that our forces struggle to destroy them in time.”

An explosion occurred at Kerch Strait Bridge this morning. Ukraine’s Security Service (SBU) on 3 June confirmed it carried out an operation to damage the Kerch Bridge from below the waterline, marking the third time Ukrainian forces have struck the Russian-built structure connecting occupied Crimea with mainland Russia. 

According to the SBU, the operation targeted the underwater supports of the Crimean bridge—known by Russia as the Kerch bridge—with specially planted explosive devices. The agency reported that the attack was launched precisely at 4:44 a.m., damaging the bridge at the level of its underwater support pillars.

The explosives used amounted to 1100 kg in TNT equivalent, the SBU stated, describing the bridge as now in a critical or near-emergency condition. The SBU emphasized that the explosion caused no civilian casualties.

SBU head Vasyl Maliuk personally coordinated and supervised the planning and execution of the mission. He stated:

“God loves the Trinity (Ukrainian saying used when something occurs for the third time, – Ed.), and the SBU always finishes what it starts and never repeats itself. We struck the Crimean bridge twice before, in 2022 and 2023. Today, we continued that tradition—this time from underwater.”

Legitimate military target

Maliuk justified the strike as a response to Russia’s continued occupation of Ukrainian territory and the use of the bridge as a key supply route for Russian military operations in southern Ukraine.

“No illegal object of the Russian Federation has any place on the territory of our state,” he said. “The Crimean bridge is an entirely legal target, especially considering that the enemy used it as a logistical artery to supply its troops. Crimea is Ukraine, and any signs of occupation will be met with a tough response.”

Damage remains unverified

The full extent of the underwater damage has not yet been independently verified. However, the SBU’s statement indicates significant harm to the bridge’s structural supports at the seabed level. Russia has not yet commented on the event at the time of publication.

At least seven people were killed and dozens more injured after two bridges collapsed in Bryansk and Kursk oblasts overnight on 1 June, striking passenger and freight train routes and raising questions over infrastructure failures or sabotage. Russian law enforcement initially attributed the incidents to Ukrainian sabotage, but later removed the claim.

Train hit by collapsing highway bridge in Bryansk

According to the governor of Russia’s Bryansk Oblast, Alexander Bogomaz, a highway bridge on the federal A240 route allegedly collapsed onto a moving passenger train near the settlement of Vygonichi. The train was operating on the Moscow–Klimovo line. Regional sources, including Telegram channels such as Astra and Baza, reported that a freight truck was crossing the bridge at the moment of the collapse.

Bogomaz confirmed the incident involved both vehicles and a passenger train. Moscow Railway stated that the train derailment resulted from the collapse of the bridge, which occurred due to “illegal interference in transport operations.” The Russian Investigative Committee later reported the bridge had been blown up at 22:50 local time.

Astra published photos and videos of the aftermath.

As of the morning of 1 June, Russian reports indicated at least seven alleged fatalities and 66 injured individuals in the Bryansk collapse, with 47 hospitalized.

Freight locomotive derailed in Kursk after second bridge collapse

In Kursk Oblast’s Zheleznogorsky district, another collapse occurred on a railway bridge during the movement of a freight train. Acting governor Alexander Khinshtein reported that part of the train allegedly fell onto the highway running below the bridge. A fire broke out on the locomotive, and one crew member was reportedly injured.

The Investigative Committee of Russia, launched investigations into both incidents on terrorism-related charges.

Astra shared visuals showing the destruction at the 48th kilometer of the Trosna–Kalinovka road, confirming the scale of the incident.

Unconfirmed third incident

Telegram channels SHOT and 112 reported another incident in Bryansk Oblast, claiming that railway tracks were blown up near the settlement of Unecha on 1 June as a track inspection train was passing. Governor Bogomaz later stated that as of 10:52, railway workers discovered track damage in the Unecha–Zhecha section during an infrastructure inspection, with no casualties reported.

Previous Russian infrastructure collapses noted by Ukrainian Stratcom

Ukraine’s Centre for Strategic Communication listed prior incidents of Russian bridge failures, pointing to chronic infrastructure decay and mismanagement. These include:

• April 2024 – Vyazma, Smolensk Oblast: Paninsky overpass collapse killed one and injured five.
• October 2023 – Buryatia: A railway bridge over the Dzhida River collapsed due to rainfall and neglect.
• July 2022 – Zabaykalsky Krai: Bridge on the Chita–Khabarovsk highway fell due to erosion and neglect.
• November 2020 – Primorsky Krai: A bridge collapsed under a truck near Vladivostok.
• July 2018 – Nizhny Novgorod: A pedestrian bridge collapsed during a festival.
• May 2015 – Krasnoyarsk Krai: Logging truck caused a collapse near Kansk.

Stratcom concluded:

“Corruption and decay are Russia’s problems, not Ukraine.”

Ukraine presented weapons that have already changed the rules of war at the European Defence Innovation Days 2025 (EDID25) exhibition in late May 2025, according to ArmyInform. 

Among the highlights were autonomous FPV drones, a new class of naval drones, and robotic ground systems transforming logistics on the front lines. 

The EDID25 forum was hosted by the European Defence Agency (EDA) in Kraków, Poland. The event brought together developers, military personnel, scientists, and industry leaders from across Europe.

Twelve Ukrainian companies showcased their innovations. According to Anatolii Khrapchynskyi, deputy director of an electronic warfare company and military expert, Ukraine did not come with concepts, but with real, battle-tested technology.

“These are not mock-ups. These are technologies that save lives and are changing the rules of modern warfare,” Khrapchynskyi emphasized.

Among the systems demonstrated:

• FPV drones with autonomous targeting, capable of striking without an operator, due to computer vision.
• Naval drones that have learned to intercept airborne targets — effectively a new class of weapons
• Mavic- and Matrice-type drones, fully assembled with Ukrainian-made electronics
• Ground robotic systems that revolutionize frontline logistics, remotely mine terrain, and establish new firing positions 

“Our technologies are not just innovation. They are combat experience transformed into solutions. We know how to turn challenges into breakthroughs,” said Khrapchynskyi.

A key takeaway for European partners is that Ukraine is becoming not just a production hub but a source of experience, flexibility, and strategic thinking.

That is why Khrapchynskyi stressed the need to establish an Engineering Command Center in Ukraine, a permanent hub for military innovation staffed by Ukrainian and European experts.

This center should:

• Translate battlefield experience into technical specifications;
• Anticipate the needs of future wars;
• Coordinate cross-sector development of systems and platforms.

“Europe is searching for solutions. And Ukraine has the answers — practical, combat-proven, and scalable,” the expert concluded.

Earlier, the Security Service of Ukraine reported that a total of 34% of Russia’s strategic missile carriers based at their main airfields were hit in the operation SpiderWeb, which targeted at least four airfields. 

Ukraine used smart FPV-drones launched from cargo trucks to target the aircraft. 

A Russian military train was blown up near the occupied town of Yakymivka in Zaporizhzhia Oblast overnight on 31 May, damaging fuel wagons and a vital supply route used by Moscow’s forces to support occupied Crimea, Ukraine’s defense intelligence agency reported.

According to Ukraine’s Main Intelligence Directorate (HUR) of Ukraine’s Ministry of Defense, the explosion occurred on the railway line close to Yakymivka in the Melitopol district. The freight train, which included fuel tanks, was moving toward occupied Crimea when the blast hit. As a result, freight cars and tanker cars went off the rails, and the track was severely damaged.

HUR described the targeted section as “a key logistical artery of the Russians on the occupied territories of Zaporizhzhia Oblast and Crimea.” The agency stated that this disruption undermines Moscow’s ability to maintain military logistics in the south.

In response to the attack, Russian occupation forces declared a standard police “interception plan” across the occupied part of Zaporizhzhia Oblast, HUR reported. Authorities increased the number of military patrols in local settlements and intensified checks at checkpoints.

Recent attacks and incidents on Russian trains and infrastructure

On 25 May, Ukrainian military intelligence reported a drone strike on another Russian freight train transporting fuel in the occupied part of Zaporizhzhia Oblast.

That same evening, a train in Russia’s Belgorod Oblast was damaged after hitting an explosive device, according to regional governor Vyacheslav Gladkov.

In the early hours of 1 June, two bridge collapses occurred in Bryansk and Kursk oblasts. In Bryansk, a car bridge collapsed onto a passenger train, killing at least seven people. In Kursk, an accident on a railway bridge involving a freight train was reported, with no initial casualties mentioned.

A drone strike carried out by Ukraine’s Main Intelligence Directorate (HUR) of the Defense Ministry destroyed a Russian military train carrying fuel in occupied Zaporizhzhia Oblast reportedly on 24 May. The operation targeted the Tokmak–Molochansk–Fedorivka railway section, located some 50 kilometers south of the frontline.

According to a 25 May report by HUR, the drone unit of the agency’s active operations division struck the moving train while it was transporting fuel for Russian military equipment. The agency confirmed that “at least three fuel tankers were destroyed,” severely disrupting the occupiers’ logistics.

HUR described the operation as part of a broader armed campaign aimed at “obstructing and paralyzing Russian military logistics” across occupied Ukrainian territories. Footage of the strike was released on HUR’s official website, showing explosions engulfing the tankers.

Rail logistics under increasing pressure

As noted by the defense-focused outlet Militarnyi, the route itself sustained damage during the attack, further complicating Russian efforts to transfer and support troops in Zaporizhzhia Oblast and Crimea.

The Cyberboroshno OSINT community reported that the train was hit in the settlement of Novobohdanivka in Melitopol district, located about 50 kilometers from the active combat line.

Militarnyi highlighted ongoing efforts by Russian forces to restore and expand rail infrastructure on occupied territory, particularly in Donetsk and Zaporizhzhia Oblasts. These include constructing a new railway connection between Rostov-on-Don and occupied Crimea through Zaporizhzhia’s Berdiansk, intended to reduce reliance on the Crimean bridge and improve transport safety for military cargo. Additionally, Russia plans to resume freight operations with Melitopol and to upgrade the Mariupol–Rostov-on-Don line to strengthen connections with occupied Crimea.
