The Czech Republic has secured funding to continue delivering artillery ammunition to Ukraine into next year, but the future of this initiative may depend on the results of the upcoming parliamentary elections in October.

Czech program closes Ukraine’s artillery gap

Czech Foreign Minister Jan Lipavský told Bloomberg in an interview that the Czech-led program to source heavy ammunition for Ukraine, funded by a coalition of 11 countries, has significantly changed the situation on the battlefield. According to Lipavský, Ukrainian forces, who at the start of Russia’s full-scale invasion in February 2022 had only one artillery round for every ten fired by Russia, now have one for every two.

The Czech Republic has committed to delivering 1.8 million shells to Ukraine this year under this program. Lipavský described the effort as a “game changer” and emphasized that it plays a vital role as US support weakens and efforts by President Donald Trump to end the war remain stalled.

Political future of the ammunition effort uncertain

Despite the success and international backing of the initiative, Lipavský warned that its continuation hinges on maintaining political support after the Czech parliamentary elections scheduled for 3–4 October 2025.

“We’ve secured funding for next year,” said Lipavský, adding that the Czech Republic has also trained 9,000 Ukrainian soldiers and intends to begin training Ukrainian pilots. “What is absolutely crucial is to preserve political support for the ammunition initiative after Czech parliamentary elections,” he said.

Polls indicate that the current center-right government led by Prime Minister Petr Fiala is trailing behind former Prime Minister and billionaire Andrej Babiš, who is leading ahead of the vote.

Babiš has openly criticized supplying arms to Ukraine and hosting Ukrainian war refugees.

Far-right ties and NATO defense spending on agenda

Lipavský accused Babis of “far-right populism,” referencing the ex-premier’s alignment with Hungarian Prime Minister Viktor Orbán and France’s National Rally in forming a nationalist bloc in the European Parliament last year.

The battle for air superiority is no longer just about seeing — it’s also about hearing. In 2025, Germany plans to launch combat drones equipped with acoustic sensors that can detect the origin of enemy artillery fire, Army Inform reports. 

According to Hartpunkt, German company Quantum-Systems, in collaboration with Polish firm Weles Acoustics, is integrating advanced acoustic detectors into reconnaissance UAVs. These sensors capture sound waves from artillery and mortar fire, allowing for rapid identification of enemy firing positions.

Weighing under 50 grams, the sensors operate in the 20 Hz to 10 kHz range and can detect shots from up to 15 km away. Directional accuracy reaches 5° at a 5 km distance. Integration with neural networks enables the system to automatically identify weapon types, distinguishing, for example, a howitzer from a mortar.

In the initial phase, the operator receives a signal and visually confirms the target. In the future, machine vision algorithms will handle targeting automatically.

The technology is designed to:

• Reduce the time needed to locate enemy batteries
• Improve counter-battery effectiveness
• Minimize losses among Ukraine’s defense forces

Defense Express notes that a major challenge is filtering out noise from drone rotors and wind. Still, field test results have been convincing, and serial production is planned for late 2025.

Earlier, experts reported that Russia likely used a new jet-powered attack drone, the Geran-3, in a recent missile and drone strike on Kyiv. This model marks a significant upgrade over the slower Shahed-136 (Geran-2), boasting reported speeds of 550–600 km/h and a range of up to 2,500 km, compared to the Shahed-136’s 185 km/h.

Residents of Kyiv reported hearing a distinct whistling sound during the strike, consistent with a jet-powered drone and unlike the quieter propeller-driven models previously used. 

A 17-year-old boy has died in hospital from injuries sustained during the Russian rocket artillery strike on the city of Sumy on 3 June, raising the total death toll to six. “Doctors fought for his life for nearly a week,” local authorities reported on 10 June.

On 3 June, Russian forces shelled central Sumy city in northeastern Ukraine, reportedly using the Tornado-S multiple launch rocket systems. According to President Volodymyr Zelenskyy, the strike was a deliberate attack on civilian areas.

“Russians savagely hit Sumy. Just the city, ordinary streets – with rocket artillery. A completely deliberate strike on civilians. A rescue operation is underway now,” Zelenskyy said back then.

The President also highlighted that at least one rocket did not detonate. The unexploded munition penetrated the wall of a ninth-floor apartment.

Casualties and aftermath

On the evening of 3 June, officials reported four people killed and 28 injured in the attack. Among the wounded were three children.

On 4 June, the death toll rose to five after an 86-year-old woman died in hospital from injuries sustained during the shelling.

Now, the latest victim, the 17-year-old boy, passed away nearly a week later despite intensive efforts by medical personnel.

War intensifies amid Russia’s summer offensive. Ukraine has spotted a massive redeployment of Russian self-propelled artillery and air defense systems to Sumy Oblast. 

Ukrainian forces have recorded a large-scale transfer of Russian military equipment from Crimea and Kherson towards Sumy Oblast. According to Petro Andriushchenko, head of the Occupation Studies Center, this is the largest movement of weaponry in the past six months.

“More than 10 self-propelled artillery systems, air defense systems, and convoys of over 40 trucks carrying ammunition and personnel,” Andriushchenko says.

The equipment is being loaded onto trains and sent to Russia’s Kursk Oblast, effectively heading to Sumy. The Russians are now stationed approximately 25-30 km from it. If they reach the city’s border, they will use artillery to strike it. 

Special attention is drawn to the military equipment markings, which, with their dominant tactical symbol of a triangle within a triangle, indicate reinforcement of this specific direction.

Amid this buildup, Sumy faces heavy drone attacks. Konotop mayor Artem Semenikhin stated that on 8 June, the region endured the most powerful drone assault since the war began: “The entire sky over the region turned red with targets.”

Russia is fielding rare 140 mm and 60 mm mortars from North Korea in its war on Ukraine, with new photos marking the first visual confirmation of their use in combat, according to NK News.

Militarnyi, citing NK News, reports that North Korea has delivered towed 140 mm mortars to Russian forces, following earlier transfers of 60 mm mortars. The artillery pieces, previously limited to D​PRK parades and museum displays, are now appearing alongside Russian troops operating in the Kursk Oblast. 

Photos shared by Russian military bloggers show several 60 mm mortars reportedly provided by North Korea to Russian paratroopers of the 76th Guards Air Assault Division. These troops, reportedly operating with D​PRK personnel in the Kursk area, were seen in combat positions with the mortars.

Expert assessment and origin of the weapons

Joost Oliemans, an expert in North Korean military systems, stated the photographs are the first evidence that these weapons are now actively used in the Ukraine war. He noted that the 60 mm mortar may have been North Korea’s attempt to imitate NATO-standard weaponry. Russian propagandists claim the mortar’s effectiveness remains unclear, according to Miltitarnyi.

Oliemans also explained that the larger 140 mm mortar was developed by North Korea during the 1980s and 1990s. The first known appearance of this system was during a military parade in 1992 marking the 60th anniversary of the D​PRK armed forces. He added that the model likely dates back to 1981.

Rising dependence on unusual calibers

Militarnyi notes that despite the growth in D​PRK arms supplies, Russia remains challenged by logistical issues arising from its reliance on non-standard calibers. The introduction of such unique artillery pieces complicates integration with existing systems.

In a recent development, Russia reportedly equipped one of its newly formed artillery brigades with Koksan self-propelled artillery systems, also received from North Korea.

Despite the US’s absence, the Ramstein meeting on 4 June kicked off a new era of military aid for Ukraine, with billions in investments and joint weapons production.

Ramstein moves forward without the US 

For the first time since the group’s creation, the US Secretary of Defense was absent from the meeting. 

The Pentagon explained that Pete Hegseth had a tight schedule, writes ArmyInform. He also won’t attend today’s NATO–Ukraine Council meeting, although he did arrive for the NATO ministerial and attended the Alliance’s headquarters on the morning of 5 June.

Nevertheless, the meeting results demonstrate that the rest of the allies remain committed to supporting Ukraine militarily, as confirmed by the announcement of new aid packages.

Ukraine and allies won’t just share weapons

The central takeaway from the Contact Group meeting was the agreement to create a joint defense production mechanism. Ukraine’s Defense Minister Rustem Umerov said the concept came from partners offering to help establish defense production involving Ukrainian companies.

“Our partners are ready to fully finance the production, and the products made under Ukrainian licenses will be sent to Ukraine as long as the war continues,” he explained.

During the discussions, however, the plan evolved into mutual investment: Ukrainian manufacturers will be able to invest in partner countries, while companies from these countries will be able to build large-scale factories in Ukraine.

Umerov noted that the idea is still new, with details under discussion and no official name yet.

“We’re calling it ‘Ramstein investments in the defense industry,’ but this is a strategic breakthrough,” the minister emphasized.

There are already specific agreements on joint production:

• A Western European company announced it will produce modern anti-Shahed missiles in Ukraine,
• The UK and Ukraine will jointly manufacture LMM missiles and launchers,
• Rheinmetall is building cutting-edge Lynx combat vehicles in Ukraine,
• Ukrainian companies are producing ammunition under Nammo licenses,
• SAAB, Kongsberg, KNDS, FFG, and Raytheon are all expanding their presence in Ukraine.

The SAAB produces Gripen fighter jets, Raytheon manufactures Patriot missiles, the only type capable of intercepting Russia’s ballistic missiles, KNDS makes missiles for NASAMS, and FFG is notable for supplying military vehicles and equipment, including contributing Leopard 1A5 tanks. 

“Ukrainian drones have changed the situation on the battlefield, and now they will change how Ramstein countries prepare for future threats,” Umerov stated.

100,000 drones and a record £4.5 billion in aid

Before the session even began, London announced a new aid package with a special focus on drones: 100,000 drones for Ukraine’s Defense Forces by the end of 2025, ten times more than last year, with record investments of £350 million.

Additionally, 140,000 artillery shells have already been delivered. Another £247 million will go toward training Ukrainian troops as part of Operation Interflex, which has already trained 55,000 Ukrainian soldiers.

German long-range weapons to be built on Ukrainian soil

Germany, in turn, confirmed its previously announced €5 billion military aid package. It includes funding for long-range weapons to be produced in Ukraine, as well as the delivery of air defense systems, weapons, and ammunition.

German Defense Minister Boris Pistorius assured that supporting Ukraine remains a priority both for the new German government and for him personally.

War at Sea: Netherlands, Canada, and Belgium expand maritime and electronic warfare fronts

Support for Ukraine goes far beyond just two countries. The Netherlands is focusing on maritime security: €400 million will go toward a mine countermeasure ship, boats, and maritime drones for Ukraine.

Norway is prioritizing support for Ukraine’s defense industry, allocating $700 million for drones and contributing $50 million to the NSATU fund.

Canada will provide $45 million for drones, electronic warfare equipment, and will send Coyote and Bison armored vehicles to Ukraine.

Belgium, which hosted Ramstein for the second time, announced a long-term initiative — committing to €1 billion annually in aid to Ukraine through 2029 and the delivery of a mine countermeasure vessel.

Sweden allocated €440 million for international programs to purchase artillery shells, drones, and other weaponry for Ukraine.

Today, there are a lot of interesting updates from the Kupiansk direction. Here, along the Oskil River near Kupiansk, Ukrainian special forces just carried out one of the boldest operations of the war.

In a surprise helicopter raid deep behind Russian lines, they landed undetected and tore through dugouts, safe houses, and staging zones, shattering Russian preparations before their offensive could even begin.

Hidden danger of Kharkiv Oblast town

The Russian forces in this area maintain a very thin bridgehead on the west bank of the Oskil River, where the control of the town of Dvorichna allows them to accumulate and deploy forces across the river.

Russians plan to use this bridgehead to tactically outflank Ukrainian forces in Kupiansk from the north, as well as to use it as a launching pad to link up with their other offensive in Kharkiv.

The Ukrainians understand that the Dvorichna bridgehead will be a key staging ground for the Russian summer offensive in Kharkiv, and know that they must act quickly to undermine any future Russian effort here.

The flaw in the river

The primary Russian weakness here is that their forces must cross the Oskil River by boat to reach their bridgehead on the western bank, which significantly complicates their logistics. This prevents them from deploying large numbers of heavy weapons such as anti-tank guided missiles or MANPADS.

The lack of man-portable air defenses makes the Russian bridgehead highly vulnerable to any aerial operations that the Ukrainians could conduct.

Subsequently, the Ukrainian special operations forces command devised a daring and unconventional plan, to conduct the first air assault operation in the war in over three years.

They planned to fly over Russian lines and deploy several teams of special forces in the rear of the enemy, where they would conduct raids, gather intelligence, and direct fire onto concealed Russian deployment points.

Ghosts in the trees

The Ukrainian Special Forces involved in this operation were deployed using American UH-60 Black Hawk helicopters, flying low to avoid being detected by the Russians.

Penetrating deep behind Russian lines, the helicopters were able to land and dismount several dozen Ukrainian operators before returning safely to friendly territory.

Once on the ground, the Ukrainian troops moved quickly and with purpose. After reaching their targets, they launched a series of highly effective and deadly raids against Russian forces. They cleared forest belts and residential areas of enemy soldiers who had been preparing to cross the river.

Russian troops were caught completely off guard, never expecting an attack from their rear. Several dugouts were quickly encircled, and numerous Russian soldiers were captured in the confusion.

Taking full advantage of surprise and terrain, Ukrainian operators concealed themselves in forested areas, waiting for small Russian infantry groups that were either sent to find them, or were moving to new positions completely unaware.

These ambushes were swift and lethal, as the Ukrainians eliminated enemy soldiers at point-blank range using small arms, all while remaining undetected in the dense cover of the forest.

The escape corridor

The high level of coordination and preparation of the Ukrainian forces included several armored vehicles, meant to arrive near a designated exfil point to quickly evacuate the operators. This point was chosen carefully, as it had the least amount of frontline activity, and no Russian bridgehead, making it the safest route for the job.

The Ukrainians moved through the dense forests behind the Dvorichna bridgehead and avoided areas with larger concentrations of Russian soldiers.

The Ukrainian special operators, with intelligence gained from captured Russians, enabled the Ukrainian drone operators to identify large Russian strongholds standing in the way of the Ukrainian exfiltration.

Artillery crews and heavy drone bombers were deployed, leading to the decimation of these Russian troops.

This focused fire established a corridor for the Ukrainian special forces to safely traverse the forests and reach the western bank of the river, where MaxPro armored vehicles awaited to exfiltrate them back to safety.

Operators left behind: the shadow war begins

Overall, the Ukrainians achieved the impossible, carrying out the war’s first air assault operation in over three years, allowing them to strike deep into Russian-held territory, inflict serious losses, and gather critical intelligence.

Notably, it is highly likely that not all Ukrainian operators exfiltrated from behind Russian lines.

According to special forces doctrine, these operators will be able to gather intelligence, set up and train further resistance networks, and conduct a deadly guerrilla warfare with sabotage and liquidations of top Russian commanders.

Russia is going to go all-in this summer, and the Ukrainians are positioning themselves to take every advantage they can to repulse it.
