Russia’s aircraft plants still turn out modern fighter-bombers and fighters, enough to partly cover its losses, Ukraine’s military intelligence agency HUR told Ukrainian news agency UNIAN, which published the reply on 23 October. Its older bombers are a different story. Russia has no serial production of new Tu-95s, Tu-22M3s, or Su-24s and keeps them flying through repairs and upgrades, so each one lost for good leaves a lasting gap, HUR said.

Ukraine’s Navy said its Neptune missiles hit six Su-34M bombers at Borisoglebsk airbase in Russia’s Voronezh Oblast overnight into 15 October. Zelenskyy later said four were destroyed and two damaged. The Su-34 is one of the jets that drop Russia’s glide bombs, heavy bombs fitted with wing-and-guidance kits, on Ukrainian positions and towns.

How fast Russia replaces its jets

Russia can probably deliver 10–15 Su-34s a year now, HUR estimated. Deliveries grew from eight in 2022 to 11 in 2023 and 12–14 in 2024. But the agency said that trend does not confirm the same pace today.

For the Su-35S fighter, HUR pointed to an average of about 11–12 a year in 2021–2025. It called that a rough benchmark, not an established 2026 output. Su-30SM2 and Su-57 production continues, but reliable rates cannot be determined. Su-30 figures also mix new builds with upgrades of older Su-30SMs, HUR noted.

What Russia had, and what it lost or saw badly damaged in 2026

By the end of 2025, Russia had about 125 Su-34 and Su-34M bombers, which HUR counts together. It also had 140–145 Su-30 jets of various versions, 135–140 Su-35S, and about 20 Su-57s, HUR estimated. These are only fleet estimates, not a guaranteed number of jets Russia can send on combat missions at the same time, the agency cautioned. Some are under repair or upgrade, and HUR is not disclosing the current fleet size.

HUR also named specific 2026 cases of Russian aircraft destroyed or critically damaged. A Tu-22M3 crashed in Irkutsk Oblast on 15 June. Strikes on Engels airbase on 17 July and 28 August hit two Tu-95MS. The first suffered critical damage to its tail section, and HUR treats the second as a probable irrecoverable loss.

The list also includes a Su-35 that Ukraine’s military says it shot down on 8 July, a claim backed by published materials showing debris. It adds a Su-57 crash in Moscow Oblast on 23 July and a collision of two Su-35S over Kursk Oblast on 7 September. Full official details on those two incidents are still missing, HUR noted. Strikes on several Su-57s and a Su-34 at Shagol airbase on 25 April, and on a Su-24 in Crimea on 7 September, were also reported, but the state of those jets is unknown, so counting them as destroyed would be premature, HUR said. The list, as published, leaves out the Su-34s at Borisoglebsk and the Tu-95MS that Russia’s defense ministry said crashed on takeoff in Amur Oblast in late September.

Ukraine’s Navy hit six Su-34M bombers at Russia’s Borisoglebsk military airfield in Voronezh Oblast with Neptune missiles overnight into 15 October, the Navy said. Residents filmed a large fire at the base after a missile alert, and the Navy’s count has not been independently confirmed. The facility is about 400 km from the frontline.

Glide bombs are now central to how Russia’s army fights, used to pin down Ukrainian defenders, including drone teams, before small infantry groups move in. They also hit frontline cities and the civilians who live in them.

Six bombers and flight equipment hit, the Navy says

The Neptune coastal missile system also hit technical equipment that supports flights, the Navy said. It recorded secondary detonations and a fire on the airfield and said details were still being clarified.

The Su-34M can carry several guided and high-explosive aerial bombs at once, along with missiles, the Navy noted. It called the jet one of Russia’s key tools for glide-bomb strikes on Ukrainian positions and frontline towns. In September, a Ukrainian Neptune missile reached a Russian warship at its own pier.

Fire over the airfield late on 14 October

Voronezh Oblast Governor Aleksandr Gusev declared a missile alert across the region shortly before 22:00 local time on 14 October. Within an hour, Ukrainian monitoring channel Exilenova+ reported explosions and a fire, preliminarily at the Borisoglebsk airfield. It later wrote that the airfield had come under missile attack and a fire was burning there. Ukrainian monitoring channel Supernova+ posted footage from the town showing the blaze.

On the morning of 15 October, Gusev claimed that 33 drones and several jet-powered aerial targets had been downed over the oblast overnight. He did not mention the airfield.

A base Ukraine has hit before

The airfield hosts the 783rd training aviation center and units of the 105th composite aviation division of Russia’s Aerospace Forces, which flies Su-34, Su-35S, and Su-30SM jets, Ukrainian defense outlet Militarnyi reported. In summer 2026, it had no permanently based combat jets, and Russia used it mainly as a stopover to refuel and rearm aircraft striking Ukraine, the outlet said, citing satellite observation.

Ukrainian drones hit the airfield overnight on 8 July, starting a fire, and satellite images later showed its fuel and lubricants depot destroyed. Drones also attacked the base’s pilot training center in July 2025.

The same night, Ryazan Oblast Governor Pavel Malkov reported a fire at an oil refinery in Ryazan. It came as Ukrainian President Volodymyr Zelenskyy said Ukraine was resuming strikes on Russian refineries.

Update: Satellite imagery confirms the strike

New satellite images show damage at Borisoglebsk airbase and six Su-34 bombers positioned in the affected area two days earlier, although the extent of the aircraft losses remains unconfirmed.

The monitoring channel Exilenova+ reports that 4 airframes were completely destroyed, while 2 others sustained significant damage.

Russian forces struck the eastern Ukrainian city of Kramatorsk on the morning of 8 October, hitting two route buses carrying residents and killing dozens of civilians. The Donetsk Oblast prosecutor's office opened a war-crimes investigation.

Russia has turned everyday movement in frontline Donetsk Oblast into a lethal risk, striking city buses, ambulances, and cars in places its army has not been able to capture.

A route bus run turned deadly

The attack came at around 10:00, catching two route buses in the impact zone. The prosecutor's office said the attackers likely used a UMPB D-30SN. HUR, Ukraine's military intelligence, describes it as a guided glide bomb that can fly up to 100 km when released from an altitude of 12–15 km and carries a warhead equal to a FAB-250 aerial bomb.

The toll rose through the day, from 12 dead in the first reports to 30 killed and 20 wounded by 14:55, Donetsk Oblast head Vadym Filashkin said. Across Donetsk Oblast, Russian attacks killed 33 people that day, including the 30 in Kramatorsk and three in nearby Bilenke, the State Emergency Service said. Ukrainian President Volodymyr Zelenskyy said the strike would not go unanswered.

Buses pulled off the roads

Filashkin ordered the Kramatorsk and Sloviansk city military administrations to suspend public transport, citing the sharp deterioration in security. Buses had become an attractive target for Russian forces, he said, and the authorities could not risk the lives of passengers and drivers. He also urged everyone still in Donetsk Oblast to leave for safer parts of Ukraine. Kramatorsk is a frequent target of Russian attacks. Russia had not commented on the strike as of publication.

The city has been under daily fire. On 5 October, Russian FPV drones hit ambulances and an apartment block in Kramatorsk, killing a woman and wounding four, the prosecutor's office reported. Over the previous day, Russian forces shelled Donetsk Oblast settlements 31 times and 256 people left the front line, Filashkin said.

The UN Human Rights Office verified some 15,280 civilian casualties in Ukraine during the first eight months of 2026, 55% more than in the same period last year, UN High Commissioner for Human Rights Volker Türk said on 2 October.

Türk's statement comes as Russia has begun its Winter 2026-2027 campaign of long-range strikes against Ukrainian energy infrastructure. The Institute for the Study of War (ISW) said Russian forces began the campaign in late September. Damage to energy infrastructure disrupt electricity, heating, and water supplies during the winter, increasing the risks to civilians.

Russian glide bombs killed and injured nearly 2,500 civilians in Donetsk, Kharkiv, Sumy, and Zaporizhzhia oblasts during the first eight months of the year, 62% more than in the same period last year, according to UN figures.

"As winter approaches, Ukrainians fear the worst is yet to come," Türk said.

On 4 October, Russia's Defense Ministry announced that it was intensifying strikes on infrastructure in Kyiv City and Oblast and across Ukraine, according to ISW.

Why Russia is turning to long-range strikes

ISW said Ukraine's 2026 battlefield successes "appear to be forcing" Russian President Vladimir Putin to shift focus from advances on the battlefield toward a winter campaign intended to compel Ukraine to surrender.

A week earlier, ISW assessed that Putin was likely attempting to force Ukraine to capitulate before spring 2027, with his theory of victory heavily relying on cheap, jet-powered Geran-type drones.

A toll rising all year

The 15,280 figure extends a trend the UN has tracked all year. Over the first seven months of 2026, its monitoring mission verified 1,839 civilians killed and 10,638 injured. In September, UN Under-Secretary-General Rosemary DiCarlo told the Security Council that more civilians were killed or injured in the first eight months of 2026 than in all of 2025.
