The refinery is one of the largest fuel-processing facilities serving Moscow. According to Defense Express, it has a processing capacity of up to 11 million tons of oil annually and supplies a significant share of the city’s gasoline, diesel fuel, and aviation fuel demand.
Defense Express reported that drones approaching the target would have had to penetrate several defensive rings deployed around Moscow.

Open-source mapping cited by the outlet indicates the Russian capital is protected by at least three established air-defense belts, largely consisting of Pantsir air-defense systems positioned on towers and elevated structures. A fourth outer defensive ring is reportedly under development.
The refinery itself was additionally protected by anti-drone netting designed to reduce the effectiveness of unmanned aerial attacks. Videos published by local residents and referenced by the outlet showed a fire at the facility following the strike.

The extent of the damage has not been independently verified, and Russian authorities had not released a detailed assessment of the refinery’s condition at the time of publication.
The June 16 strike was not the first reported Ukrainian attack on the Moscow Oil Refinery. According to Defense Express, the facility was also targeted in September 2024, March 2025, and May 2026.
Earlier, Russia expanded Moscow’s air defense network by creating a new division reportedly equipped with S-500 Prometey systems. Despite the additional defenses, Ukrainian long-range drones have continued to reach targets in and around the Russian capital.
