Ukraine Struck 18 Russian Oil Facilities in May, the Farthermost being 1700 km From Frontline

Throughout May 2026, the geographic scope of Ukrainian deep-strike operations extended to more than ten regions of the Russian federation, including Moscow, Vladimir, Kirov, and Samara oblasts with the longest-range strike reached 1,700 kilometers from the state border.

This was Ukraine’s response to Russia’s prolongation of the war and its attacks on Ukrainian cities and communities, The Ukrainian MoD said in a statement.

Long-range strikes against Russia were intended, in part, to deprive the enemy of the economic capacity to continue its aggression. Deep-strike operations also strengthen Ukraine’s path toward ending the war from a position of strength.

The Ministry of Defence of Ukraine presents an overview of Russia’s losses resulting from Ukrainian long-range strikes in May.

18 oil refining and fuel logistics facilities struck

Last month, units of the Defence Forces of Ukraine halted or significantly disrupted operations at least 18 major russian oil refineries with a combined design processing capacity of more than 110 million tonnes of crude oil per year.

Among the key strike include:

Perm oil refinery and the Perm line production and dispatch station (LPDS), Perm (Perm Krai), ~1,500 km.

Industrial infrastructure in Perm Krai, including the LUKOIL-Permnefteorgsintez refinery, was subjected to a series of long-range strikes. Using UAVs, Ukrainian defenders damaged the AVT-2 and AVT-4 crude distillation units, an isomerization unit, and one of the process storage tanks at the Perm line production and dispatch station (LPDS).

The refinery has a design processing capacity of approximately 13 million tonnes of crude oil per year and specializes in producing petrol, diesel fuel, and aviation fuel.

The Perm LPDS functions as a strategic distribution hub, routing crude oil in four directions across Russia’s pipeline network.

Metafrax Chemicals plant, Gubakha (Perm Krai), ~1,700 km

Precise strikes completely halted technological and production processes at the facility.

This giant of russia’s chemical industry is a critically important component of the country’s industrial base, supplying products to dozens of russian defense enterprises. The plant’s products are used in the manufacture of aircraft, unmanned systems, rocket engines, and military explosives.
