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.

Ukraine's new defense minister went to Kherson Oblast days after Russia destroyed the heat of its main city. Yevhenii Khmara visited the region and met the head of the regional military administration, Oleksandr Prokudin, to discuss the region's most urgent needs, the Defense Ministry reported.

Russia hit the Kherson combined heat and power plant with a glide bomb on 26 August, then struck it again overnight with four more, destroying all the heat- and power-generating equipment that remained, Naftogaz said.

Prokudin has urged residents to leave, warning the city may go without heat and power through the winter. He said that Russia has dropped 170 glide bombs on the oblast since 1 July, more than in the entire first half of 2026.

Air defense topped the agenda

Khmara and Prokudin discussed strengthening defenses against various types of drones and protection against aerial bombs, as well as the safety of roads and critical infrastructure, which are being attacked by Russians day and night. They also addressed giving troops in this direction more capacity to strike the Russian targets that threaten civilians and soldiers.

The needs match the threat Prokudin has described. No region of Ukraine currently has the means to shoot down jet-powered Shaheds or glide bombs, he said, and Russia has begun using both more heavily against Kherson's infrastructure.

The minister met marines and the wounded

Khmara spoke with commanders and troops of the 30th Marine Corps operating on the Prydniprovskyi direction, the ministry said. The talks covered financial support for combat units and larger purchases of strike systems.

"We have taken up the soldiers' requests that need Defense Ministry decisions," the ministry said.

Khmara also visited a medical facility treating wounded troops and presented state awards.

The ministry frames it as direct contact

The Defense Ministry said it plans to keep working directly with troops and the leadership of front-line regions to strengthen the Defense Forces and protect Ukrainian lives.

Sweden will transfer 10 coast guard boats to Ukraine, the Swedish government announced on 27 August 2026. Stockholm will also direct additional funds to multilateral defense programs for Kyiv.

Russia's full-scale invasion added to some 13,500 km² of Ukraine's rivers, lakes, and Black Sea coastline now potentially contaminated with explosive remnants of war, in the world's most mined country, and emergency service divers had cleared 190 km² of it by November 2025. Allied nations have committed billions in military support to Kyiv since 2022, from fighter jets to anti-drone systems.

Rescue boats for Ukraine's mined waterways

Ukraine's State Emergency Service will receive the work and high-speed vessels in their current condition, after the coast guard removes their markings and equipment. The agency will use them for waterborne rescue operations, including clearing mines from river channels.

Sweden's Civil Defense Minister Carl-Oskar Bohlin said Sweden is further strengthening Ukraine's maritime capabilities. He described towage, mine clearance, and transport as important capabilities that can now increase further. Sweden's Civil Defense Agency will handle transporting the boats to Ukraine.

The donation follows Sweden's broader naval support for Kyiv. In January 2025, Stockholm doubled its pledge of CB90 assault boats for Ukraine's navy to 32 and added 23 naval combat modules to arm them. The coast guard vessels serve a different purpose—rescue and utility work for a civilian agency, not combat operations.

Another $28 million for defense funds

Sweden will also channel 270 million Swedish kronor (about $28 million) to multilateral defense funds supporting Ukraine, mainly for air defense. Of that sum, $14 million goes to the Prioritized Ukraine Requirements List (PURL), to which Sweden contributed $108 million in June. Allies and partners fund high-priority American materiel through the US-led, NATO-administered program, and this package covers advanced air defense systems and ammunition for Kyiv.

A Russian drone company is developing an interceptor drone—the cheap counter-drone weapon Ukraine has fielded at scale against Russian attack drones—internal documents published by the Russian resistance group Black Spark describe, the defense outlet Militarnyi reported. The documents describe two designs under consideration, and Black Spark alleges the company cooperated with Boeing before the full-scale invasion and spied on European companies.

Interceptor drones—unmanned aircraft that hunt other drones—scaled up out of Ukraine's need to shoot down Russia's mass Shahed attacks without spending million-dollar missiles on them. Ukraine now fields them from dozens of licensed makers, and their spread has pushed Russia toward faster jet-powered attack drones. Russia already flies anti-drone interceptors of its own—Ukrainian troops downed one in July—and the leaked designs would fly far faster than that machine.

Mortar-launched drone-killer

NIK is considering two interceptor designs. The first modifies the company's existing UBB-M, a folding-wing loitering munition that launches from a 160 mm container by mortar-style ejection. For the interceptor role, designers changed the wing from straight to swept, shrank the wingspan, installed a larger battery, and fitted a more powerful motor.

The modified drone weighs 15-16 kg, carries a 3 kg payload—likely a warhead—and flies at 250-300 km/h with a 20 km operating radius and up to 10 minutes of flight time, operating between 20 meters and 4.5 km altitude. NIK's second design has a cone-shaped fuselage with four electric motors. Its specifications remain unknown.

Espionage claim comes with no documents

Black Spark says the documents came from someone inside the company, not a break-in, and that it holds evidence the firm spied on European companies. It gave no details on the Boeing cooperation beyond dating it before the invasion.

The leak is Black Spark's latest operation against Russia's defense industry. The group, which operates inside Russia, says it infiltrated the Alabuga factory where Russia assembles Shahed-derived Geran drones and copied personnel databases. Ukraine's Special Operations Forces have acknowledged joint missions with Black Spark, including attacks on Russian oil infrastructure.

Moldova will invest in air defense after repeated Russian drone incursions, Moldovan President Maia Sandu said, RFE/RL reported. She spoke at the country's independence celebrations on 27 August alongside the Ukrainian and Romanian presidents, hours after another group of drones entered Moldovan airspace during Russian strikes on Ukraine. The Institute for the Study of War (ISW) says the crossings show Putin continuing to normalize the threat that Russia's strikes on western Ukraine pose to European states.

"We cannot be intimidated"

Russian drones have violated the airspace of Moldova and Romania dozens of times, Sandu noted. She met Romanian President Nicușor Dan and Ukrainian President Volodymyr Zelenskyy in Chișinău for the anniversary.

"And today, on the eve of our holiday, Russian drones invaded our airspace with the obvious aim of intimidating us. And now I want to say clearly, in the presence of our friends—we cannot be intimidated. We are investing in air defense in order to have the capability to protect our people and infrastructure," she said.

Sandu also called on every country of the free world to help Ukraine, and specifically to strengthen its air defense before winter. While Ukraine fights in the east, she said, Moldova can sleep calmly. Russian drones have breached Moldovan airspace repeatedly before this month.

Five drones from the Ukrainian border

Moldova's Defense Ministry reported five unidentified drones entering Moldovan airspace from various points along the border area with Ukraine in Odesa Oblast early on 27 August, the day after a single drone crossed the border and left minutes later. The five crossings ran from 03:56 to 06:02, and each drone flew over the country briefly before turning back toward Ukraine, following Russian air attacks there, the ministry said.

ISW says these incidents show that Putin continues to normalize the threat that Russia's strike campaign against the westernmost parts of Ukraine poses to European states, including Moldova and eastern NATO members. The crossings also show the Kremlin accepting the risk that its war can damage other states. 

Moldova is not in NATO or the EU, and it is a neutral state. Russian drones have crossed its airspace illegally around 70 times since the start of the full-scale war, Moldova's National Army says. Defense Minister Anatolie Nosatîi called the situation extremely serious after one incursion this month halted air traffic over the country for 15 minutes, and said the army needs modernizing.

Romania shoots, Bulgaria clears up

Unlike Moldova, the NATO members in the region act on what reaches them. Romania intercepts what crosses in, and Bulgaria destroys what drifts to its coast:

• 26 June: Bulgaria's navy destroyed a drifting drone seven nautical miles off Kranevo.
• 21 July: Bulgarian, Romanian, and Turkish ships destroyed a drifting drone 21 nautical miles off Ahtopol.
• 24–26 July: Romanian F-16s downed three drones, the country's first shootdowns at home.
• Early August: Romanian jets scrambled before Ukraine shot the drone down.
• 16 August: a Spanish F/A-18 downed a drone north of Galați, the fourth over Romania this year, the Defense Ministry said.
• 20 August: a Romanian F-16 destroyed an explosive-laden sea drone with its cannon near an offshore gas platform. President Nicușor Dan blamed Russia.
• 22 August: two more drone wrecks turned up on Bulgarian beaches, one of them a Russian decoy without a warhead.
