Summary of Ukrainian attacks on Russia, June 2–3
When the St. Petersburg International Economic Forum opened on the morning of June 3, the delegates Vladimir Putin had gathered to showcase a "modern and thriving" Russia were greeted by columns of black smoke over the city's port. Overnight, Ukraine had run one of its most geographically ambitious long-range drone campaigns of the war - striking an oil export hub on the Gulf of Finland, warships at the Kronstadt naval base, and a missile-components plant 600 kilometers behind the front. The timing was not incidental. This was the fifth wartime edition of the forum Russian state media bills as "Putin's Davos," the event meant to prove sanctions have not isolated Moscow. Ukraine answered by putting fire and air-raid sirens into the host city itself.
What was hit, and where
Three target sets, stretching from the Baltic coast to Russia's defense-industrial interior.
The Petersburg Oil Terminal, on the Gulf of Finland inside the Great Port of St. Petersburg, took the most visible damage. Residents reported a series of loud explosions shortly after 04:00 local time, followed by a large fire across the port area. The terminal sits roughly 1,100 kilometers from Ukraine's border - among the deepest strikes Kyiv has landed - and only about 17 kilometers from the Expoforum convention center where forum delegates were arriving that same morning.
At Kronstadt, one of the two main bases of Russia's Baltic Fleet, Ukrainian drones struck ships and port infrastructure. Robert "Madyar" Brovdi, commander of Ukraine's Unmanned Systems Forces, released footage of a strike on the corvette Boiky, reportedly hit while in dry dock. Ukraine's General Staff later confirmed that units had struck a Project 20380 Steregushchiy-class corvette and that a large-scale fire was confirmed on board, with the extent of damage still being clarified.
The third blow landed far inland, at the JSC Progress plant in Michurinsk, Tambov Oblast - about 347 kilometers from Ukraine's northeastern border. Footage geolocated by the independent Russian channel Astra showed a fire on the facility's grounds. Tambov Governor Yevgeny Pervyshov acknowledged only an attack on the "outbuildings of an industrial enterprise," declining to name the site.
The casualty and interception picture
The strikes followed a brutal Russian barrage the night before. On June 2, Russia hit Kyiv and other Ukrainian cities with more than 70 missiles and 650 drones, killing at least 23 people - including two children - and wounding over 100. Ukrainian officials framed the June 3 operation explicitly as part of bringing the war's costs home to Russia after that attack.
On the Russian side, casualty reporting was sparse and, as usual, downplayed. Russia's Defense Ministry claimed air defenses downed more than 350 drones overnight across western Russia, and reported two firefighters killed. St. Petersburg Governor Alexander Beglov said infrastructure in the Kirovsky, Krasnoselsky, and Kronstadt districts was hit, with several people injured.
The interception numbers tell their own story about the scale and duration of the raid. Leningrad Oblast Governor Aleksandr Drozdenko updated his tally through the night: 3 drones downed by around 04:00, 30 by 06:00, and 50 by 07:00 - a steady three-hour stream rather than a single salvo. Moscow Mayor Sergei Sobyanin reported more than 20 drones intercepted over the capital starting the evening of June 2, with additional drones downed in the early hours of June 3. The Tambov region saw drones damage an apartment building, a library, and an arts school in Michurinsk, though local authorities reported no casualties there.
Disruption rippled well beyond the impact sites. Pulkovo Airport, St. Petersburg's main hub and the gateway for arriving forum delegates, delayed 29 departures for more than two hours and diverted nine aircraft to alternate airfields; some reporting put the operational pause at close to five hours. Airports across Moscow and Leningrad oblasts suspended operations.
Why these targets
Each target was chosen for what it feeds into Russia's war machine, not for symbolism alone - though the symbolism was considerable.
The Petersburg Oil Terminal is one of Russia's largest fuel storage and export facilities and the largest petroleum-products transshipment complex in northwestern Russia. It is a 37-hectare site with 21 storage tanks for light and heavy fuels, and a reported annual throughput of 12.5 million tons. It receives petroleum products by river, rail, and road, then loads them onto sea tankers for export - making it a direct artery for the oil revenue that funds the war. Moscow has formally designated it a facility of strategic importance for national security. Ukraine's SBU described the strike as "a sign of things to come," noting that the Kremlin earns its petrodollars through exactly these refineries, depots, and terminals. Hitting it on the opening day of the forum meant for advertising Russia's economic resilience sharpened the point considerably.
The Progress plant is a more surgical choice. According to Ukraine's Defense Intelligence (HUR), it produces high-tech equipment for aviation and missile control systems - specifically MP-95 sensors used in producing the Kh-101 air-launched cruise missile, and GMS-01D gyro motors used in the Kh-59M2 and Kh-59M2A guided missiles. It also reportedly makes components for the Pantsir-S1 air defense system. These are precisely the weapons Russia fires at Ukrainian cities, including in the June 2 barrage. The plant has now been struck four times - after hits in December 2024, June 2025, and February 2026 - reflecting how persistently Ukraine targets nodes in the missile-production chain that are hard to replace under sanctions.
Kronstadt may be the most strategically significant of the three. Defense Express noted the naval strike could outweigh the oil-terminal hit: the base is a major hub for repair, modernization, training, coastal defense, and fleet logistics, typically hosting around 20 to 25 combat ships and boats plus several dozen auxiliary vessels. The corvette Boiky is a Project 20380 multipurpose warship - roughly 2,220 tons, 104.5 meters, a crew of about 100, armed with a 100mm A-190 gun, Uran anti-ship missiles, the Redut air defense system, Paket-NK anti-submarine torpedoes, and a Ka-27 helicopter. Damaging warships and repair infrastructure at a Baltic Fleet base demonstrates that Ukraine can now reach not only energy targets near St. Petersburg, but the navy's basing and maintenance backbone far from any front line.
The strategic significance
Read together, the operation is a statement about reach and intent. Across a single night, Ukraine demonstrated it can credibly threaten energy export infrastructure, naval assets, and weapons-production facilities at ranges of 350 to 1,100 kilometers - and do so simultaneously, forcing Russian air defenses to spread thin across western Russia, Moscow, and the Baltic approaches.
President Volodymyr Zelensky tied the strikes together under what he called Ukraine's "long-range sanctions," carried out by the SBU, the Unmanned Systems Forces, the Special Operations Forces, Defense Intelligence, and the State Border Guard Service. The phrasing is deliberate: where Western sanctions work slowly and leak at the edges, Ukrainian drones impose costs immediately and visibly on the specific facilities that finance and arm the war. Denys Shtilerman, co-founder of the Fire Point drone-maker, framed it with dark humor - saying Ukraine had wanted to give forum guests "an excursion to the cruiser Moskva," but settling instead for "two other ships already at the venue."
The forum context turns a military operation into a political one. SPIEF exists to project the image of a Russia open for business and unbowed by isolation, with delegates from over 130 countries due to attend through June 6 and Putin scheduled to address them on June 5. Smoke over the port, a shuttered airport, and naval ships ablaze a short drive from the convention hall undercut that message in real time, in front of the exact audience it was staged for.
The harder question this raises is about Russia's air-defense math. Claiming 350-plus drones downed sounds impressive until you account for the ones that got through - to a strategically designated oil terminal, a Baltic Fleet base, and a missile plant deep inside the country, all in one night. As Ukraine's strike range and drone volume keep climbing, no Russian city, port, or industrial site can any longer be treated as safely beyond the front.
