Russia is concentrating missiles on a smaller, more specific set of targets, and its jet-powered attack drones are part of the reason, the Institute for the Study of War (ISW) assessed. Its combined attack overnight on 7 October killed 22 people in Pryluky, the State Emergency Service (SES) said as of the morning of 8 October. Russian milbloggers noted the shift the same day.

Russia often uses concentrated drone and missile strikes to overwhelm localized Ukrainian air defenses and destroy urban centers, ISW noted. Pryluky, where the strike killed children, was one of the areas a Russian channel says drew a significant share of the Kh-101s that night. With winter close, ISW expects the same pattern against Ukraine's energy grid, with jet drones partly letting Russia keep its missiles for priority targets without firing many more.

Missile waves on a few areas, Russian channels claim

Russia launched 48 Kh-101, Iskander-K, and Kalibr cruise missiles overnight on 7 October, Ukraine's Air Force reported. It also fired ballistic missiles, Zircon and Oniks anti-ship missiles, and 130 strike and decoy drones, 46 of them jet-powered Shahed-type models.

22 killed in Russian missile strike on Pryluky, including five children

Russian milbloggers claimed the same day that Moscow had grouped a large part of its missile salvo into repeated waves on a few areas, while other weapons kept stretching Ukraine's air defenses elsewhere. The pro-war Russian Telegram channel Dva Mayora described the change as a switch from striking with splayed fingers to a series of hits with missile "fists." Defenders must then absorb a sharply rising load around one chosen site as one wave follows another, the channel claimed.

Citing Ukrainian monitoring channels, it claimed that roughly 30 or more Kh-101 cruise missiles flew toward Pryluky, Kremenchuk, Svitlovodsk, and Oleksandriia in Chernihiv, Poltava, and Kirovohrad oblasts. It put the Kremenchuk group at up to 15 missiles, Kh-101s and Kalibrs among them, aimed at the area of Kremenchuk and its hydroelectric plant.

Jet drones take some of the load off Russia's missiles

ISW said the jet-powered versions penetrate Ukrainian air defenses deeper and more reliably than propeller models. In ISW's assessment, that partly lets Russia concentrate cruise and ballistic missiles on priority targets without significantly raising missile use. Russia builds about 3,000 Geran-4 and Geran-5 jet drones a month, Ukraine's military intelligence agency (HUR) told Militarnyi in August.

Ukraine spent three years learning to catch Russian drones—so Russia made them fly faster

ISW expects Russia to apply the pattern in a likely brutal winter campaign against energy infrastructure. Russia likely intends to make city life untenable and force Ukraine to capitulate to its demands, ISW assessed. Such tactics have not worked before and are unlikely to work now, analysts added.

They called cheap countermeasures to jet drones and small cruise missiles vital, alongside Western air defense aid such as US-made Patriots, which can stop ballistic missiles. Ukraine has already paired a Soviet-era Kub launcher with American RIM-7 interceptors to catch jet drones.

Russia launched a large-scale missile and drone attack across Ukraine overnight into 7 October, killing at least 11 people and injuring more than 30. Kyiv, Pryluky, Kremenchuk and several other cities were struck as Moscow used ballistic and cruise missiles alongside 130 attack drones, with energy infrastructure among the principal targets.

Russia fired 70 missiles and 130 drones at Ukraine during one of the largest combined aerial attacks of recent months, striking Kyiv and at least a dozen regions between Tuesday evening and Wednesday morning.

President Volodymyr Zelenskyy said at least 11 people had been killed and 34 wounded in the attacks. He said energy infrastructure was among Russia’s principal targets and described ballistic missiles as the most difficult element of the assault for Ukrainian air defences. Reuters reported the remarks and casualty figures.

According to the Ukrainian Air Force’s preliminary assessment, the attack began at about 6pm on 6 October and involved a mixture of ballistic, anti-ship and cruise missiles launched from Russian territory, aircraft and the Caspian Sea. Russia also deployed 130 Shahed-type, Gerbera and decoy drones, including 46 jet-powered attack drones.

By 9am, Ukrainian forces said they had destroyed or electronically suppressed 161 aerial targets: 117 drones, 39 cruise missiles and five ballistic or other high-speed missiles. Six additional cruise missiles were still being assessed. Missile and drone impacts were recorded at 18 locations, while debris from intercepted weapons fell at another five.

The main directions of attack were the Kyiv, Kharkiv, Poltava and Dnipropetrovsk regions.

Residential buildings hit in Pryluky and Kyiv

Some of the heaviest civilian casualties were reported in Pryluky, in Chernihiv region, where a missile struck a multi-storey residential building. Emergency officials initially reported four people killed and 20 injured, including three children. Rescue teams continued searching the damaged structure on Wednesday morning. Associated Press reported on the rescue operation and casualties.

In Kyiv, ballistic missiles reached the capital during the night, with explosions reported shortly after 3am. Two people were killed. A non-residential building in the Podilskyi district was hit and caught fire, while garages burned in Darnytskyi district. The wider Kyiv region was simultaneously attacked by missiles and drones, damaging three production and warehouse facilities in the Obukhiv district.

Two people were also killed and seven wounded in Kremenchuk, in Poltava region, where missiles and drones struck the city and surrounding district. Damage was reported to residential buildings and an industrial facility. Further strikes were recorded in Dnipro, Zaporizhzhia and Oleksandriia.

Zelenskyy said Russia had deliberately sought to inflict serious damage on Ukraine’s energy system. “One of the key targets was our energy infrastructure,” he said, adding that further air-defence supplies had become an immediate requirement.

The attack came only hours after the Ukrainian president said intelligence services had obtained information indicating that Russia was preparing another major aerial operation. In his address on Tuesday evening, he urged Ukrainians to respond to air-raid warnings and said the country’s ability to withstand the expected attack would depend partly on the availability of Western-supplied defensive systems. His latest statements are available through the official presidential website.

The scale and composition of Wednesday’s barrage again exposed the pressure being placed on Ukraine’s layered air-defence network. EU Today has previously examined the shortage of Patriot interceptors capable of engaging ballistic missiles, which travel considerably faster than cruise missiles and drones and leave defence crews much less time to respond.

Russia’s use of different weapons within the same attack also forces Ukraine to employ several types of interception simultaneously. Cheap drones can be engaged by mobile fire groups, electronic warfare and interceptor drones, while ballistic missiles generally require more sophisticated systems such as Patriot.

Moscow’s Defence Ministry said its forces had carried out a “massive strike” using long-range precision weapons and drones against Ukrainian military-industrial facilities. It claimed that missile and drone production and storage sites, as well as port and ship-repair infrastructure, had been targeted. Those claims could not independently establish the nature of individual sites hit. Ukrainian authorities meanwhile documented damage to homes, businesses, energy facilities and other civilian infrastructure.

The overnight assault follows several weeks of intensified strikes as Ukraine approaches another winter under pressure on its power network. During German Chancellor Friedrich Merz’s visit to Kyiv at the weekend, Berlin announced a new assistance package of more than €1.3 billion, including military support and funding intended to help protect and repair the country’s energy infrastructure ahead of winter.

Wednesday’s attack demonstrated why those two areas — air defence and the resilience of the electricity system — have become increasingly closely connected. Even with more than 160 incoming weapons intercepted or suppressed, missiles and drones reached targets across several regions, leaving casualties and damage hundreds of kilometres apart.

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.
