Ukraine has found the US component in a Russian jet-powered drone targeting civilians, supermarkets, medical warehouses, and bridges. According to its Defense Intelligence, the new weapon contains a PNI5GA magneto-inductive sensor made by the US company PNI Sensor.

The US-made navigation component adds to evidence that Western technology continues to appear in Russia's strike drones. HUR had already identified US-made chips in the Geran-4 in May, but the newly reported PNI5GA is a navigation sensor in a modified version of the drone that Institute for the Study of War (ISW) says Russia may seek to field ahead of winter.

A Russian engine replaces the Chinese one

Russia has also replaced the drone's Chinese-made Telefly turbojet engine with a Russian-made equivalent produced in Alabuga. Russia is using the Alabuga zone to bring more of its drone production home rather than importing Iranian or Chinese parts, according to the ISW.

"The remaining electronic units and components are unchanged and identical to those used in previous Geran UAVs," HUR said.

What the warhead is built to cut

The modified drone also carries a specialized KRSN warhead designed to cut through bridge structures and power-line supports. Presidential adviser Serhii Beskrestnov described the warhead on 30 September, saying it consists of a 40-kilogram main charge and four strike modules. Its warhead is meant to destroy hardened targets made of steel and concrete and to damage cable-stayed bridges.

Russia has stepped up strikes on Kyiv's Northern and Southern bridges across the Dnipro in recent days with such drones.

However, Russia may try to field more resilient and more dangerous versions of its strike drones before Ukraine has effective countermeasures in place. Russia could use them to degrade Ukraine's energy infrastructure and logistics ahead of a winter strike campaign that it said will very likely be brutal.

Ukraine has developed a new missile to knock down Russia's fast, jet-powered Shahed drones, the ones its air defenses catch far less often than older models, President Volodymyr Zelenskyy said on 4 October, Suspilne reported. The weapon, called Nika, has not yet been tested. He announced it during a visit to Kyiv by German Chancellor Friedrich Merz.

Russia's plants turn out an estimated 3,000 jet-powered Geran-4 and Geran-5 drones a month, Ukraine's military intelligence estimates, and the jets fly fast enough to outrun the cheap interceptors built for slower, propeller-driven Shaheds. Ukraine plans about 400 units of just one of five interceptor models it is testing by the end of October, as it scrambles to close the gap before winter.

A new missile heads into testing

Both the Ukrainian and German sides have reacted positively to the missile, Zelenskyy said, though he stayed cautious on the result: for now, he said, it only "could be positive." In the same remarks, he announced a successful test of a separate system, the German-Ukrainian interceptor Spys.

Ukraine shoots down 85-92% of propeller-driven Shaheds, Zelenskyy said. Against the jet-powered variants, interception falls to roughly 50-60%, he noted at the press conference with Merz. F-16 fighter jets help close the gap, he said.

From interceptor drones to a new missile

Over the past month, Ukraine tested a new generation of drone interceptors built for the jet-Shahed threat. On 15 September, one struck a Shahed in trials, though Zelenskyy said developers still needed to refine its control system. On 19 September, he said the Security Service of Ukraine (SBU) had created its own interceptor drone and used it to down a jet Shahed in combat. Nika adds a purpose-built missile to that mix.

A Russian strike on an apartment building in Kharkiv injured dozens of people, many of them children, early on 28 September, regional prosecutors reported. Through the rest of the day, Russian drones hit Kyiv, Dnipro, and other cities, killing civilians in several of them.

Russia has moved much of its aerial campaign to jet-powered drones that fly too fast for the cheap interceptors Ukraine built against older models. Every switch to a faster weapon reopens gaps in city defenses that Ukraine had only just begun to close.

Two floors partly destroyed in a Kharkiv apartment block

Russia hit a nine-story building in Kharkiv's Saltivskyi district around 04:00. By early afternoon, the count had risen to 43 injured, including 11 children, prosecutors said.

A man of 43 and a girl of 14 remain in hospital with blast wounds, and the others have moderate or light injuries, Kharkiv Oblast head Oleh Syniehubov said. Three children lived in the apartment that took the hit. Their father carried them out himself, and none of them was seriously hurt.

The strike hit the second floor and destroyed the ceiling between the third and fourth floors. Rescuers brought 32 people out of the building. Across the district, the attack damaged 18 apartment buildings and blew out more than 1,500 windows. More than 100 volunteers are helping city services seal them, Syniehubov added.

A resident who fled Kramatorsk a year and a half ago said her family never heard the blast itself.

"We didn't hear any explosion. Glass came pouring down, and a column of smoke stood there," Yuliia Baldzhy told Suspilne Kharkiv. "The children were sleeping in another room, and my husband and I barely squeezed through, grabbed them, and got out."

Kharkiv Mayor Ihor Terekhov said the city had not taken a hit "of this level" in some time. Officials are still establishing the weapon. Syniehubov named guided aerial bombs (KABs) and counted six of them over the oblast in the past day. Prosecutors named a UMPB-5, a Russian munition, as the preliminary version. Terekhov said the city was checking whether it was a KAB or a Banderol, a small cruise missile.

Russia has hit Kharkiv high-rises with guided bombs before. In November 2024, one such strike injured 25 people, including an infant.

Kyiv hit through the night and into the day

In the middle of the working day, a Russian jet drone struck the main building of the National Academy of Sciences in Kyiv's historic center. The attack killed a woman and injured five people, the Kyiv City Military Administration said. Three of them were hospitalized, Klitschko said. People climbed out of windows to escape the fire.

"Russia will definitely get a response to this," Ukrainian President Volodymyr Zelenskyy said.

Overnight and into the morning, Russian drones hit a gas station in Obolon, a café by a gas station, office buildings, and a 16-story residential building in Podil. The attacks injured three teenagers in Podil, Kyiv Mayor Vitali Klitschko said. A 17-year-old boy was hospitalized.

Nationwide, Russia launched 165 drones overnight, 79 of them jet-powered, the Air Force reported. Air defenses downed or suppressed 112, and hits were recorded at 14 locations.

The capital is now under attack daily. On 27 September, Russian strikes injured nine people in Kyiv, and Russia hit a Kyiv data center twice. That evening, a Russian drone struck the Stolychnyi market in Sofiivska Borshchahivka, just outside the city, and killed two people. Zelenskyy wrote that one of the two killed in Kyiv Oblast was a citizen of Azerbaijan.

Deaths in Dnipro and Synelnykove

Around 11:15, a Russian drone hit a business center in central Dnipro, killing three people. The number of injured rose to 15, Dnipropetrovsk Oblast head Oleksandr Hanzha said. Rescuers led 47 people out of the burning building, regional council head Mykola Lukashuk said.

"Nearby are residential buildings, a park, a library, offices, shops. The center of Dnipro. In the middle of the working day, hundreds of people are here," Hanzha wrote.

In Synelnykove, a Russian strike on a logistics company's branch killed one person. It injured three others, including a 15-year-old boy now in hospital in serious condition.

Overnight, Russian drones also hit infrastructure in the Vasylkivka community and a market in Nikopol.

Strikes across other regions

In Kharkiv Oblast on 27 September, a Russian FPV drone killed a 67-year-old driver in Shestakove, prosecutors said. A drone on fiber-optic control also killed a 41-year-old woman in a car in Velykyi Burluk and injured a 46-year-old man.

Explosions sounded in Poltava overnight. In Rivne Oblast, a Russian attack damaged a detached house without injuring anyone. In Odesa Oblast, Russia struck a warehouse, and an evening attack injured a man of 62 and a woman of 63. Zelenskyy also listed a Palau-flagged ship hit in Odesa Oblast and an ice cream plant damaged in Zhytomyr Oblast, in the same post.

Ukraine's defense forces intercepted 55% of Russia's jet-propelled drones in September—more than 1,500 out of over 2,730 launched—Ukrainian President Volodymyr Zelenskyy said in his 26 September evening address.

Russia's full-scale aerial campaign has shifted from propeller-driven Shaheds Ukraine learned to shoot down at over 90% to jet-propelled models that fly faster, resist jamming, and often slip past existing defenses.

55% and climbing

Zelenskyy said military intelligence had briefed him on Russian weapons production—not just jet Shaheds but other technological systems. The documents detail what Moscow is preparing for next year: the volumes and the financing. "We are preparing our countermeasures, and for every line item there must be a Ukrainian answer," he said.

Several effective interceptor prototypes are already in combat.

"Interceptors have been identified that can become the main tool of our defense. Production, components—all of this we are scaling up. There will be an answer," Zelenskyy said.

The goal is to match the interception rate for regular propeller-driven Shaheds, which exceeds 90%. At 55%, the jet-drone rate is climbing but still leaves nearly half reaching their targets.

$12 billion for one category

Russia plans to spend $12 billion in 2027 on jet drones and loitering munitions alone, Zelenskyy said. "This concerns not only Ukraine and not only us," he added, warning that multiple intelligence agencies have information Russia wants to expand its war to other countries and regions.

He said this is why Ukraine is pushing for stronger sanctions and the Drone Deal format. Ukraine has signed 11 such agreements, the latest with Finland at the UN General Assembly this week, and is preparing a 12th with what Zelenskyy called "a strong country."

The warning came as Russia struck a Kyiv data center twice on the morning of 27 September, injuring three people including two children, Zelenskyy wrote. Overnight strikes killed three people in Zaporizhzhia Oblast and one man in Kyiv.

In total this week, Russia launched more than 2,200 strike drones, roughly 1,650 aerial bombs, and 38 missiles—a significant share of them ballistic—at Ukraine, he said.

Jet drones are now Russia's main aerial weapon

Russia's jet-propelled Geran-4 and Geran-5 drones have become the dominant threat in Russia's aerial campaign against Ukrainian cities. By August, production of jet Geran-4/5 models exceeded that of propeller-driven Geran-2s, according to Ukraine's military intelligence (HUR). Russian factories produce roughly 3,000 jet models per month alongside about 2,800 of the older type. The Geran-5 is technically a drone but functions as a small cruise missile—faster, harder to jam, and increasingly guided by AI and mesh networking that complicate interception.

Ukraine's answer has been interceptor drones—cheap, fast enough to chase a Geran, and guided by machine vision. A Ukrainian interceptor recently scored its first kills against jet Gerans and is heading into mass production, though a presidential adviser warned that speed alone cannot catch them—machine vision and automatic guidance decide the chase.
