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 authorities left residents in and around Moscow without air raid sirens or phone alerts during Ukraine's largest combined strike on Moscow Oblast, apparently to guard turnout at Russia's parliamentary elections, the Institute for the Study of War (ISW) said. The silence angered residents and even pro-war commentators as a major oil refinery burned.

For most of this war, Russia has handled strikes on its cities as a routine to be announced, warned about, and waited out. Withholding warnings during the heaviest raid yet, in the middle of a national vote, suggests authorities will trade residents' safety for the look of a calm election when a political milestone is on the line.

Sirens stayed off during the biggest raid

Ukraine hit strategic sites across the Moscow area overnight on 19-20 September, the last day of Russia's State Duma vote. Moscow Oblast officials did not switch on air alert sirens or send the SMS warnings they had used during far smaller attacks. They quietly restricted mobile service without major public notice. Ukraine struck oil and logistics targets, not polling stations, according to the experts, and authorities appeared to place high turnout above protecting civilians.

Moscow Oblast residents complained that no alert reached them, some posting on the Telegram channel of regional Governor Andrei Vorobyov before it closed comments. A prominent Kremlin-linked military blogger attacked the official response, saying it erodes public trust and that cutting mobile service does "not really help."

What the drones hit

Ukraine's General Staff reported striking the Gazpromneft-Moscow Oil Refinery in the city's Kapotnya district, one of Russia's largest plants, causing a large fire. Ukrainian manufacturer Fire Point said its FP-1 drones completely shut down the refinery, with all primary processing units damaged.

Governor Andrei Vorobyov claimed air defenses countered 249 drones across 17 municipal districts. The strike was part of Ukraine's widening campaign against the fuel sector funding Russia's war, with about a fifth of Russian refining capacity offline.
