03.05.2026

On the night of May 3, Ukrainian drones launched a massive strike on the Leningrad region. The target of the attack was once again the largest Russian oil port in the Baltic Sea.

According to preliminary data, explosions occurred in Primorsk, Vyborg, and Ust-Luz. This is reported by Russian Telegram channels.

Attack details

An air alert in the Leningrad region was declared on May 2 at around 11:00 p.m. At the same time, monitoring channels reported that UAVs approached seaports closer to 2:00 a.m.

The FIRMS (Fire Information for Resource Management System) mapping platform recorded a large-scale fire in the port of Primorsk. As of the morning of May 3, several fire centers had broken out there at once.

Leningrad Governor Alexander Drozdenko confirmed the drone attack on the region. According to him, air defense forces shot down 59 UAVs overnight. However, the official decided not to comment on the fire in the port and other consequences on the ground.

It is worth noting that the distance from Ust-Luga and Primorsk to the state border of Ukraine is over 1,100 km.

What is known about the company?

The Primorsk Sea Commercial Port is Russia’s largest oil-loading hub in the Baltic and the end point of the Baltic Pipeline System. The enterprise specializes in the export of crude oil and light petroleum products (mainly Euro-5 diesel fuel).

The designed throughput capacity is up to 75 million tons of oil and 20 million tons of diesel fuel per year. The port is capable of shipping over 1 million barrels of oil daily.

What preceded

In March 2026, the port was the target of a large-scale drone attack. According to satellite images, about 40% of the tank capacity (at least 8 tanks) was damaged. This led to temporary disruptions in logistics and a decrease in transshipment volumes.

Against the backdrop of sanctions and technical damage, a sharp drop in shipments was recorded at the end of 2025 (up to 70% in some periods). This is due to refusals from large buyers and damage to infrastructure.

Primorsk is called a key hub for the operation of the so-called “shadow fleet”, through which Russian oil is exported, bypassing price restrictions, mostly to India, China, and Turkey.

As a reminder, the Defense Forces’ strikes on Russian oil infrastructure have reduced production volumes at Russian refineries . Average daily processing has fallen to 4.69 million barrels per day.

As OBOZ.UA reported, according to a report by the American Institute for the Study of War, the Ukrainian army has significantly scaled up its campaign to destroy key Russian economic and logistics facilities. This April was a turning point, as thanks to the increase in domestic UAV production, Ukraine has moved to massive strikes, as such attacks overload the Russian air defense system and reach targets deep in the rear.
