The Security Service of Ukraine (SBU), in tandem with the Armed Forces of Ukraine (AFU), has claimed operational responsibility for a highly destructive weekend air campaign that bypassed the Russian capital’s elite air defenses and heavily degraded occupied infrastructure in Crimea.
In a statement published to the intelligence agency’s official Telegram channel on Sunday, May 17, SBU Head Major General Yevhenii Khmara confirmed that specialized drone operators from the Center for Special Operations “Alpha” managed to simultaneously hit heavily fortified domestic manufacturing assets and frontline military airfields.
Penetrating the Moscow defense ring
While the Russian Ministry of Defense claimed to have neutralized over 550 Ukrainian drones across 14 separate regions overnight, SBU flight logs and corresponding ground telemetry confirmed that precision munitions cleanly hit several highly sensitive targets inside the Moscow region.
Specifically, long-range drones directly impacted the Angstrem Semiconductor Plant in the closed manufacturing hub of Zelenograd. As one of the primary domestic suppliers of specialized microchips and semiconductors for the Russian military-industrial complex, the facility remains under strict US federal sanctions.
Simultaneously, the Moscow oil refinery in Kapotnya suffered a direct strike that triggered a localized explosion, leaving 12 industrial workers injured and disrupting local fuel processing loops.
Furthermore, Ukrainian drone fleets cleanly penetrated outer defenses to ignite the Solnechnogorsk and Volodarskoye oil pumping and storage stations. These two critical energy logistics chokepoints serve as foundational transit nodes feeding the major fuel pipeline loops that encircle the Russian capital.
“These operations are of critical importance for weakening the military potential of the Russian Federation,” Khmara stated, emphasizing that bringing the war directly to the highly insulated Moscow region eliminates the Kremlin’s sense of domestic security.
Decapitating air defenses at Belbek airfield
Concurrently with the raids around Moscow, Alpha Group drone squads launched a synchronized long-range assault against the Belbek military airfield near Sevastopol in occupied Crimea, a primary operations node for Russian tactical aviation over the Black Sea.
The airfield assault successfully neutralized a Pantsir-S2 anti-aircraft complex, directly knocking out point-defense missile and radar hardware. The precision strike also targeted a strategic S-400 radar installation hangar, blinding regional early-warning tracking capabilities across the Black Sea.
Furthermore, the operation crippled an Orion drone management system and a Forpost ground station, severing localized communication loops for Russian reconnaissance UAVs. The attack concluded with direct impacts on a ground-to-air data transmission hub, the main control tower, and an active airfield hangar, heavily complicating immediate combat sortings for local fighter regiments.
On Saturday, Ukrainian deep-penetration units heavily damaged the massive Nevinnomyssky Azot chemical plant in Stavropol Krai – a main supplier of raw nitric and acetic acids used to forge high-explosive artillery shells.
Those operations occurred alongside successful drone strikes that completely halted motor fuel assembly lines at Gazprom’s Astrakhan gas processing unit and triggered toxic “black rain” over the city of Ryazan following a direct hit on the Rosneft oil refinery.
The SBU leadership reiterated that these surgical joint operations will continue to systematically expand in geographic scope, treating energy infrastructure and microelectronics supply chains as high-priority military assets that directly fuel the Kremlin’s cross-border shelling campaigns against Ukrainian civilians.
