Direct proof of use
The S-350 Vityaz is documented in Russian service during the 2014 Russia-Ukraine War as a fielded air-defense system rather than a transferred Ukrainian weapon. The earliest clear public reporting tied it to Russian war operations in August 2022, when The War Zone identified S-350 launchers and radar components in Russian Ministry of Defense video from Taganrog Air Base, less than 40 miles from Ukraine.
Later reporting placed the system closer to the battlefield. Defence Blog reported that Russian Ministry of Defense footage showed S-350 deployment and operation with a missile brigade in the Donetsk region in July 2024. The War Zone then reported a Ukrainian-released video showing the destruction of a Russian S-350 launcher in Donetsk region, while Defense Express reported a January 1, 2026 drone strike on a 50N6E radar component of the S-350 system in Donetsk region.

Timeline
The public record begins with S-350 equipment appearing in Russian airbase-protection duties during the full-scale phase of the war. In August 2022, The War Zone assessed Russian Ministry of Defense video and satellite context as evidence of S-350 elements at Taganrog Air Base, with launchers, radar, and support equipment protecting an airbase used for Russian operations against Ukraine.
By 2024 and 2025, reporting shifted from rear-area base defense to battlefield air-defense coverage and losses. Defence Blog reported Russian Ministry of Defense footage of S-350 operations in Donetsk in July 2024; The War Zone reported the destruction of a launcher in Donetsk region in February 2025; and Ukrainian and defense reporting described further strikes on S-350 radar equipment in 2026.

Narrative
Russia used the S-350 in the war as part of layered air defense. The system's reported tasks were protection of airbases, field forces, and important rear-area or front-adjacent positions against Ukrainian aircraft, drones, guided rockets, and missiles. The documented Taganrog deployment was outside Ukraine but directly tied to Russian air operations in the war; later Donetsk and Zaporizhzhia reporting places S-350 components within occupied or front-line Ukrainian theater areas.
The available sources document deployment, operation, and losses more clearly than individual missile firings. Defence Blog cited Russian Ministry of Defense footage and a Russian commander claim about intercepting HIMARS rockets, but independent public reporting more consistently verifies the presence and targeting of launchers and 50N6E radar components. The clearest source-backed conclusion is that Russian forces fielded the S-350 for medium-range air defense and force protection in the conflict.
