Ukrainian Drones Target Russian Air Defense Systems in Donetsk and Zaporizhzhia Regions

Ukrainian Drones Strike Key Russian Air Defense Assets

Units of Ukraine's Unmanned Systems Forces (UUS) have conducted a series of successful drone strikes against Russian air defense systems in the Donetsk and Zaporizhzhia regions. The operations, reported by UUS commander Robert 'Madyar' Brovdi, resulted in the destruction of a Russian S-350 Vityaz air defense system radar, along with multiple Tor and Buk launchers.

On January 1, 2026, Ukrainian drones from the Asgard Battalion of the 412th Nemesis Separate Brigade targeted a Tor surface-to-air missile system and a 50N6E multifunctional radar of the S-350 Vityaz complex in the temporarily occupied territory of the Donetsk region. This strike followed earlier operations on December 31, 2025, when UUS units destroyed two more systems—a Tor and a Buk—within one hour in the Huliaipole and Orikhiv directions. On New Year's Eve, a third Tor system and an S-350 radar were also reportedly hit.

Impact on Russian Air Defense Capabilities

The destruction of these systems represents a significant blow to Russia's air defense network. The S-350 Vityaz, introduced in 2021, is considered a relatively new and valuable medium-range air defense system designed to replace older Soviet-era systems like the S-300PS. Its 50N6E multifunctional radar is a critical component, capable of automatically detecting up to 100 aerial targets simultaneously and tracking up to eight targets for engagement. According to manufacturer specifications, the S-350 can engage aerodynamic targets at ranges of up to 60 kilometers and altitudes of up to 30 kilometers, with limited capability against ballistic targets up to 30 kilometers.

The targeted systems are crucial for protecting Russian forces and infrastructure:

• S-350 Vityaz: A medium-range surface-to-air missile system designed to counter aircraft, drones, cruise missiles, and ballistic targets. Its destruction reduces the operational effectiveness of the entire system, which relies on centralized target detection and tracking.
• Tor System: A mobile, short-range surface-to-air missile system designed to defend against aircraft, helicopters, UAVs, and precision-guided munitions. Modern variants like the Tor-M2U can detect up to 40 targets and engage up to four simultaneously.
• Buk System: A family of self-propelled, medium-range surface-to-air missile systems. The Buk-M3, a key component of Russia's air defense network, is capable of engaging targets up to 65 kilometers away and intercepting ballistic missiles up to 50 kilometers.

Tactical Significance of Drone Operations

Commander Brovdi emphasized that these air defense systems typically operate deep behind the front lines to protect airspace from long-range strike drones. The successful strikes indicate Ukraine's continued ability to penetrate Russian air defenses using unmanned aerial vehicles, employing 'middle-strike class' weapons with powerful warheads to neutralize these valuable assets.
