Ukraine's drone interceptors work until the weather turns. On 28 July, Presidential advisor Serhii "Flash" Beskrestnov wrote that fog and cloud in fall, winter, and spring can leave an interceptor pilot unable to see more than a dozen meters, and that success rates fall as soon as winter begins, a problem that is especially severe over the sea.

Cheap interceptor drones have become one of Ukraine's main answers to Shahed saturation. But nearly every system shares the flaw Beskrestnov names: it depends on a pilot or camera seeing the target. Ukrainian and foreign teams are all racing toward the same fix, an onboard seeker head.

The method started simple

The earliest approach was primitive but cheap and effective, Beskrestnov said. A pilot flies the interceptor to the right point using the radar network, then finds the target by eye, chases it, and attacks.

Russia answered not only with jet Shaheds but with onboard electronic warfare, evasion systems, in-flight maneuvers, and rear-facing cameras to watch the sky behind, he explained. Ukraine replied with machine-vision target capture and guidance.

Bad weather remains unsolved

None of that fixes visibility, Beskrestnov wrote, and the problem hits both ordinary and jet interceptors. The way out, he argued, is an autonomous seeker head, acoustic, thermal, or radar, mounted on the interceptor itself.

A radar seeker is the ideal, in his view, because it opens the door to a fully autonomous system with no human in the loop: the network sees the target, launches the nearest interceptor, guides it by tactical radar, and the seeker locks on for the kill.

A US firm has put a price on it

Building a radar small enough for an interceptor has proven hard, and teams in Ukraine and abroad are working on it, Beskrestnov said, adding that he would not discuss the Ukrainian efforts because the subject is sensitive.

He pointed to the American company Archimedes, which he said announced a radar days ago, operating at 24 gigahertz with a 25-by-14-degree field of view and a one-kilometer lock-on range, shown in a promotional video mounted on several Ukrainian interceptors, at about $4,000 per unit. Whether it works remains to be seen, he added, given how hard the problem is.

A Ukrainian ground robot used to run 12-15 missions. Near Kupiansk, it now survives three or four. The lifespan is collapsing under the denser Russian FPV drone and mining fire, Andrii Kopach, call sign "Matematyk", who commands a ground-robot unit in the "Lava" unmanned regiment of the "Khartia" corps, told Oboronka.

Ground robots have become a daily part of the front in Ukraine. Ukrainian units ran 16,676 logistics, strike, and evacuation missions with them in June, up 122 percent since January, and the military has contracted more than 22,000 for 2026, nearly double the 2025 total. That scale runs into a wall at the front, where Russia now assigns FPV crews, including fiber-optic drones, specifically to kill the robots.

The lifespan keeps shrinking

The pace of technological change is the core problem, Matematyk said. Ukrainian makers keep improving the platforms, but cannot always keep pace with how quickly the fighting evolves.

A machine may last only three or four missions now, as in Kharkiv Oblast, where it was eight or nine before and 12 to 15 earlier still, he said. Mining, Russian fiber-optic activity, FPV activity, and a targeted focus on countering robots all drive the decline.

Speed is the missing requirement

Most robots at the front are technologically outdated in speed and suspension, Matematyk said. Current figures of 10 to 15 kilometers per hour no longer allow a machine to cross logistics routes safely.

He put the problem in an image. Gun-armed combat robots, he said, are "Persian elephants", fearsome but so slow to reach the objective that "a couple of centuries" pass first. What the army needs are "Arabian steeds" that gallop in, do the job, and gallop back.

AI defense is in development

Ukrainian troops are working with Brave1 and the Digital Transformation Ministry on AI-based active-protection systems that could autonomously detect and neutralize enemy FPVs, Matematyk said. The approaches vary, from a camera to a mini-radar to a camera paired with sound.

The countermeasures could be net launchers, or for fast machines, shotgun blasts and shrapnel, he said. The detection and response are trained on models built from the data his unit has logged over previous years. Ukraine still holds a quality edge over Russian robots through better Starlink-based communications and decentralized robot groups in its units, he added.

A NATO country's defense minister wanted Mykhailo Fedorov the day after Ukraine dismissed him. Fedorov, Ukraine's former defense minister, has agreed to advise Italian Defense Minister Guido Crosetto on defense innovation, he wrote on Telegram.

As deputy prime minister and digital transformation minister, Fedorov created the Brave1 defense-tech cluster, then ran the Defense Ministry from 14 January 2026 until his dismissal in July. The removal triggered nationwide protests through July, with demonstrators calling for his reinstatement.

Earlier, Fedorov refused every other post Zelenskyy offered, saying only the defense minister, the president, and the commander-in-chief truly shape the war.

"I thanked Guido for his personal support and for offering me the opportunity to serve as his adviser on defense innovation. In this role, I will help Italy develop modern warfare technologies," he said.

Crozetto moved within a day

The Italian minister said he called Fedorov the day after the dismissal and asked when he would come to Rome to work as an advisor.

Fedorov met Crosetto on the first stop of an international trip focused on digitalization and defense technology.

The focus stays on his own projects

Fedorov said his main focus is unchanged and that he continues working in Ukraine on his own projects to strengthen its defense and attract international resources. In the advisory role, he will help Italy develop technologies of modern war and adapt to new security challenges, he wrote.

The two discussed drones, autonomous systems, air defense, and the development of a defense-tech ecosystem. The future of defense belongs to countries that can quickly test and scale new solutions, Fedorov said, and Ukraine's experience could serve as the basis for a new defense model for Europe.

Earlier, the Ukrainian parliament approved Yevhenii Khmara as the new defense minister. During his first speech, Khmara made it clear that he would continue his predecessor's course — the technologization of the army.

He added that there "would be more Ukrainian weapons, and strikes would be more precise.

Ukraine is bolting the war's most common rifle onto its robots. A company in the Brave1 cluster has developed a turret built around the Kalashnikov that mounts on low-cost unmanned ground vehicles, the state cluster's press service told Defender Media.

Ground robots have become a daily part of the front in Ukraine. Ukrainian units ran 16,676 logistics, strike, and evacuation missions with them in June, up 122 percent since January, and the military has contracted more than 22,000 for 2026, nearly double the 2025 total.

Arming them cheaply is the next step, and the Kalashnikov is the most cost-effective option because it is already the standard rifle across the force.

The robots are already in combat

Ground drones fitted with the turret are undergoing combat testing in Ukrainian units. Fighters of the Security Service Special Operations Center "A" have used one to destroy Russian ambushes set with concealed waiting-mode drones.

The complex is built on a four-wheel chassis with airless tires and an armored body. At the core of the weapon module is a twin turret mounting two Kalashnikov rifles.

The build took under six months

The developers have received a technical assignment and a grant from the cluster to create the turret. The path from idea to finished prototype took less than six months.

Beyond the base version, the turret can be mounted on other wheeled and tracked ground robots. That flexibility is the point: one weapon module across many platforms.

The rifle choice is about scale

The developers chose the Kalashnikov because it is the most widespread small arm in Ukrainian units, according to Brave1. The cluster considers it a simple, effective solution that lets Ukraine quickly scale up strike robots for assaults and for defense against Russian infantry.

Earlier, the Ukrainian Defense Ministry said it would buy logistics and strike-ground robotic complexes under a new strategy that calls for sticking to the Defense Ministry's specifications rather than approving models one at a time.

Ukraine is turning ordinary cars into robots instead of building them from scratch. Three units of the Armed Forces received the Kaban remote-control system, which converts vehicles into uncrewed ones, developer Drone Fight Group told Defender Media.

Ground robots have become a daily part of Ukraine's front. Ukrainian units ran 16,676 logistics and evacuation missions with them in June, up 122 percent since January, and the military has contracted more than 22,000 ground robots for 2026, nearly double the 2025 total. Most are purpose-built platforms. Kaban takes the opposite route, converting vehicles that a unit already has.

The developers say Kaban was passed to the 3rd Army Corps, the 429th Separate Unmanned Systems Regiment "Akhilles", and the 49th Brigade of the Armed Forces.

The system bolts on without modification

Kaban installs on a vehicle without altering its construction and works with different models, Drone Fight Group said. It lets the operator switch between remote and manual control.

The operator navigates on a digital map, plotting routes and setting markers. Manual correction is built in for GPS spoofing cases. The system predicts its trajectory and can automatically stop the vehicle if the connection is lost.

Starlink carries the control link

The main communication channel is Starlink, and the system also supports analog video transmission and radio control, according to the developers. A vehicle can be fitted with thermal cameras if needed.

Kaban provides two-way audio and remote control of lights, infrared illumination, and searchlights, and it can pull data from the vehicle's onboard computer. Among the optional add-ons, the developers list net launchers and platforms for launching drones.

Combat testing came before the handover

Kaban is developed with support from the Brave1 cluster, and the system has already passed combat trials, according to the developers. Work continues to refine it using feedback from military units.

The Ukrainian company that taught Ukraine to hear Russian drones is now learning to listen underwater. Zvook, which develops acoustic systems for detecting drones and missiles, has begun testing hydrophones to detect vessels and other underwater objects by sound, the company said on LinkedIn.

Zvook built its name on land. Its acoustic sensors cover Ukraine at 1,000 meters and below for less than 50 million euros, a system NATO's assistant secretary-general for operations, Tom Goffus, called crazy for its cost-effectiveness. Lithuania chose the same Ukrainian acoustic technology for deployment in 2026 after Russian drones entered its airspace.

The approach stays passive

Zvook says its underwater method emits nothing, unlike traditional sonar. Active sonar sends sound into the water and listens for its return. The company's system only listens to the acoustic environment and uses the information already present in it.

That principle is familiar to the company from the air. Underwater, almost everything else changes: sound propagation, background noise, reflections, environmental conditions, and acoustic signatures create a different detection problem.

Testing comes before any product

The company says its focus now is not a finished product but real-world data. It is working out which objects can be reliably detected and classified, and where a distributed passive underwater acoustic system could have practical value.

Possible applications range from maritime security and vessel awareness to the protection of ports and critical underwater infrastructure, the company explained. Zvook added that it is seeking commercial joint testing with defense organizations, maritime operators, and infrastructure owners.

The company frames it as one method across domains

Zvook cast the shift as continuity rather than a new line of work. From listening to the sky to acoustic tracking, and now beneath the surface, the domain changes, but the principle stays the same: passive, always listening, emitting nothing, the company said.

Serhii "Flash" Beskrestnov, advisor to the president on the development of defense technologies, has highly praised the recent personnel changes in the new Ukrainian commander-in-chief's staff. He says that Mykhailo Drapatyi is appointing the most competent people available to the Armed Forces' technical directions, adding that "after many years of war, he knows most of the army's technical specialists."

The endorsement comes from Beskrestnov, an adviser to former Ukrainian Defense Minister Mykhailo Fedorov, considered the most effective in Ukraine's history. After the dismissal, he became a non-staff adviser to President Volodymyr Zelenskyy.

The technology war moves weekly

Beskrestnov rates the new appointees on temperament as much as expertise.

"The main thing is that these new heads are energetic, modern, and good communicators," he wrote.

In a war of technologies, everything changes literally every week, and "we have to react to all the enemy's challenges just as fast. Analyze, forecast, respond, and act a step ahead of the enemy," he added.

Drapatyi arrived in the same reshuffle

Zelenskyy named Drapatyi commander-in-chief on 21 July, replacing Oleksandr Syrskyi, and said in the same address that he had offered Fedorov a leadership position bringing together Ukraine's technological capabilities.

Fedorov's removal drew street protests across Ukraine. Drapatyi commands the General Staff rather than the ministry, so the appointments Beskrestnov praises sit outside the structure he left behind.

Change will be slow, he expects

"I believe big positive changes are ahead of us, but this will not happen fast, because a great deal has to change," Beskrestnov said.

He did not name any of the new appointees or their posts.

Earlier, Beskrestnov disclosed Russia's new tactics in its drones. According to him, while Ukraine's cheap interceptor drones have been knocking Russia's nightly attackers out of the sky, Russia has now bolted a jammer onto some of its own drones to blind them.

Ukraine's cheap interceptor drones have been knocking Russia's nightly attackers out of the sky, so Russia has now bolted a jammer onto some of its own drones to blind them, according to Serhii "Flash" Beskrestnov, an adviser to Ukraine's President on defense technology. He examined the system, found in drone wreckage, and mapped how it strikes back at the interceptor sent to hunt it.

Russia batters Ukrainian cities with long-range drones most nights, and Ukraine has leaned on a cheap shield—drones costing a few thousand dollars—instead of burning through far pricier missiles. Anything that dulls that shield pushes the cost of defending the sky back up.

A jammer that waits for the interceptor

The unit rides on a Geran, Russia's version of the Iranian Shahed one-way drone. It listens for the video signal an approaching Ukrainian interceptor beams back to its pilot. Its receiver reads the interceptor's working frequency, then orders a transmitter to bury that same channel in noise, Beskrestnov found.

By his first estimate, the jammer's signal runs about five times stronger than the interceptor's video link—enough to wipe the picture and any chance of steering the drone onto its target.

Seconds decide it

In Beskrestnov's account, the system detected a test transmitter and switched on jamming after about three seconds, and the feed cut out. The device stays nearly idle until a hunter comes close, then jumps to full power to smother the signal. It targets the ordinary analog video band around 5.8 gigahertz that many cheap interceptors still use.

Possible answers, include interceptors with terminal-guidance homing for the final stretch of flight, digital communication links, or transmitters set to non-standard frequencies.

An old problem for Russia's drones

Russia has tried again and again to keep its one-way drones alive against Ukraine's defenses, including wiring jammers into some Shaheds earlier this year. Spending weight and power to protect a drone from a far cheaper interceptor shows how well those cheap drones work.
