Ukrainian drone attacks struck Russian military and energy infrastructure from occupied Crimea to Dagestan, more than 1,000 km from the border.

Ukraine’s Unmanned Systems Forces (SBS) said they carried out a large-scale overnight drone operation targeting Russian military infrastructure in occupied territories and deep inside Russia, including Dagestan — more than 1,000 kilometers from the Ukrainian border.

According to SBS Commander Robert Brovdi, known by the callsign “Madyar,” Ukrainian drones conducted 186 strikes against 46 military targets during the nights of May 16 and 17.

The reported targets were located in occupied Crimea, as well as Russia-controlled areas of Donetsk, Luhansk, and Zaporizhzhia regions, alongside facilities inside the Russian Federation itself.

One of the most notable targets was a Russian Project 10410 border patrol ship located in the city of Kaspiysk in Dagestan, on the Caspian Sea coast. Ukrainian officials stated the vessel had been used for regional patrol duties and counter-air defense operations.

Ukraine also reported strikes against a protected strategic communications hub belonging to Russia’s Black Sea Fleet in occupied Crimea.

Additional targets reportedly included:

— A Tor-M2 air defense missile system in the Luhansk region;

— Port cranes in Berdiansk allegedly used for Russian military logistics;

— A fuel train, a UAV command center, a logistics warehouse, and a gathering point for Russian military leadership in the Donetsk region;

— A Russian command post near Pokrovsk;

— Telecommunications towers used by occupying forces in Zaporizhzhia region.

The operation coincided with widespread reports of drone activity across Moscow and the surrounding Moscow region overnight on May 17.

Russian media and local residents reported explosions and fires near industrial and energy infrastructure, including in Zelenograd, Khimki, and areas near the Moscow Oil Refinery.

In Zelenograd, reports indicated strikes near the facilities of JSC “Angstrem,” a semiconductor and electronics manufacturer currently under U.S. sanctions.

A fire was also reported inside the “Elma” technology park, home to companies specializing in microelectronics, instrumentation, and information technology.

Videos circulating online appeared to show a strike near the Moscow Oil Refinery, a major supplier of gasoline, diesel fuel, and aviation fuel for the Russian capital region.

Meanwhile, explosions were also reported at the Solnechnogorskaya oil transfer station in the village of Durikine. Russian sources said the facility forms part of a major fuel pipeline system supplying the Moscow region.

At the same time, occupied Crimea experienced another night of large-scale aerial alerts and explosions. Residents reported hearing air defense systems operating near military airfields, along with power disruptions in Sevastopol, Balaklava, and Fiolent.

The strikes reflect Ukraine’s growing emphasis on long-range drone warfare targeting Russian logistics, military communications, energy infrastructure, and industrial production tied to the war effort.

Neither the full extent of the damage nor independent verification of all reported targets was immediately available.
