Neptune Missile Strike on Borisoglebsk: Six Su-34 Bombers Hit, and Ukraine Ends the Refinery Pause

In brief: Ukraine's Navy says a Neptune missile strike destroyed six Su-34M bombers at Borisoglebsk air base in Russia's Voronezh region overnight on October 15, the same morning Zelensky declared the three-day pause on refinery strikes over. One night, two signals: the energy ceasefire is functionally dead, and Ukraine's home-built missiles are now reaching the glide bomb fleet on the ground.

The fire started on the apron. Overnight into Thursday, October 15, Ukraine's Navy put Neptune missiles into the Borisoglebsk military airfield in Russia's Voronezh region and, by its own count, destroyed six Su-34M fighter-bombers where they were parked. Hours later, President Volodymyr Zelensky told the Financial Times that the block on striking Russian oil refineries, held for three days at Washington's request, is gone: the block, in his words, "is out. We're done."

Take the two together and the shape of the day is clear. The energy ceasefire that Donald Trump announced on October 11 is dead in everything but name, and Ukraine's answer is a long-range campaign that now runs on two tracks at once: the refineries that fund the war, and the aircraft that deliver it.

What the Neptune missile strike hit at Borisoglebsk

The Navy's statement, posted Thursday morning, is specific: a strike by the Neptune coastal missile system on the Borisoglebsk airfield, six Su-34M bombers destroyed along with ground equipment supporting flight operations, and secondary detonations and a fire recorded on the base. The Navy added that information was still being clarified, and framed the result plainly: hitting Su-34Ms, it said, significantly weakens the enemy's aviation potential.

Zelensky's own tally, posted alongside a satellite image, was more conservative and more precise: "Four Su-34 aircraft were destroyed and two more Su-34s were hit." He credited the strike to "our Long Neptune," said the jets had been loaded with aerial bombs and used for terror against Ukrainians, and listed two more overnight targets: a drone storage and launch site in Oryol region and a target in the Black Sea. Our long-range operations will continue, he wrote.

Moscow has not acknowledged a strike on the airfield. Voronezh governor Alexander Gusev reported 33 drones and "several jet-powered aerial targets" intercepted, with debris damaging outbuildings, while residents of Borisoglebsk reported explosions and a large fire visible across the town, per the Moscow Times, which notes the six-aircraft figure could not be independently verified. The airfield sits about six kilometers east of the town, and a missile alert had been declared in the area on Wednesday evening, October 14, per Militarnyi.

Why Su-34s are the prize: the glide bomb fleet

The Su-34 is the workhorse of the weapon that has defined this year of the war: the guided glide bomb. Flying from behind the front line, Su-34s toss UMPK-kitted bombs at Ukrainian positions and frontline cities from outside the reach of most Ukrainian air defenses. Zelensky's running tallies have put Russian glide bomb use near 1,700 a week this autumn, and it was a guided bomb that killed at least 33 people at a Kramatorsk bus stop on October 8.

That is why six airframes matter more than the raw number suggests. The open-source tracker Oryx has photo-confirmed at least 43 Su-34s destroyed since February 2022, the most of any Russian combat jet, against a production run that aviation trackers put at roughly 212 aircraft delivered through the start of this year, with the Novosibirsk line adding fewer than 20 a year. Every airframe lost on the ground is a package of guided bomb sorties that never flies. And Borisoglebsk is not an isolated case: Ukraine's military reported destroying a MiG-29 near Millerovo and a Ka-27 helicopter near Yeysk in September, and earlier reported hitting two Su-57s and a Su-34 at Shagol airfield, roughly 1,700 kilometers out, per the Moscow Times.

The weapon is the second layer of the story. Neptune began life as a subsonic anti-ship missile, and its combat debut was the one that mattered: the cruiser Moskva, flagship of the Black Sea Fleet, in April 2022. Since then the design has been reworked for land attack, and in March 2025 Zelensky announced that a "Long Neptune" with a reported range of 1,000 kilometers had passed combat testing. The enlarged missile, with a bigger nose, longer body and larger fins, was shown publicly for the first time last year, per Militarnyi and Defense Express.

Borisoglebsk sits well inside that envelope, and the strike says something about who is doing the shooting. Ukraine's Navy, a force with almost no large ships, has turned its coastal missile units into a deep-strike service: the same family of missiles credited by Ukrainska Pravda with a June strike on a Russian Navy facility in Sevastopol is now reaching airfields deep inside Russia. Alongside Fire Point's FP-7 ballistic missile and the Flamingo cruise missile, Kyiv's domestic arsenal is starting to do the work that ATACMS and Storm Shadow were once rationed for.

The refinery pause is over: We're done

The Neptune strike landed in the middle of a collapsing truce. Trump announced an energy ceasefire on October 11 without coordinating with Kyiv, as the channel detailed in the ultimatum behind the energy ceasefire. Ukraine, by Zelensky's account, held fire on Russian refineries for three days to accommodate the US request. Russia did not reciprocate: overnight into October 14 it fired 39 ballistic missiles and more than 120 strike drones, hit all three of Kyiv's thermal power plants per Prime Minister Serhii Koretskyi, and left 600,000 people without power, per the Kyiv Independent.

The following night was no quieter. Kirovohrad Oblast absorbed what regional head Andriy Raikovych called its most massive attack of the full-scale war, nearly 360 drones against 26 locations, killing three residents of Kropyvnytskyi, per ArmyInform. In Kyiv, a drone came down between apartment buildings in the Pechersk district on Thursday morning, injuring at least five people per Mayor Vitali Klitschko, and overnight strikes on Dnipropetrovsk Oblast killed two more, per the Kyiv Independent.

Zelensky's conditions for restoring any pause are now explicit: more Patriot interceptors, which he called the "minimum," at a moment when US stocks are stretched. His warning about what follows if Kyiv simply complies was just as blunt. Asked about further US-Russia agreements after the Trump Russia diesel deal, he predicted the next one: "Definitely it will be gas."

Why it matters

The pattern this week is new in one respect: Ukraine is pairing escalation with target selection. Refineries squeeze Russia's fuel economy, data center strikes squeeze its cloud, and now coastal missiles are reaching the aircraft that deliver the glide bomb campaign. If the Navy's count holds, Borisoglebsk ranks among the costliest single nights for Russian tactical aviation of the war. And it was delivered by a missile Ukraine builds itself, immune to the intelligence cutoffs and Starlink restrictions that the past week put on display.

What to watch

Watch for independent satellite confirmation of how many of the six airframes are write-offs, and whether Russia disperses Su-34s to deeper airfields, as it did with strategic bombers after the Spiderweb drone raids. Watch for the first confirmed Ukrainian refinery strike since the pause lifted, and for how Washington responds to being told no. Watch Patriot deliveries, which Zelensky has defined as the price of any new pause. And watch Starlink: service in Ukraine was restored on Thursday per a Defense Ministry source cited by the Kyiv Independent, but the throttling question is not answered.
