Direct proof of use
Direct conflict-use evidence for the 9S18 Kupol in the 2014 Russia-Ukraine War comes from incident reporting on Russian Buk-family air-defense equipment struck by Ukrainian forces. Suspilne reported that, according to Ukraine's Defense Intelligence press service, HUR personnel and Omega special-purpose troops destroyed a Russian 9S18 Kupol target-detection station, a 9K37 launcher-loader, and a Buk system near Svatove in occupied Luhansk region on August 30, 2023.
Army Recognition separately reported the same September 2023 Buk-M1 incident and identified the destroyed set as including a 9K37 Buk-M1 launcher, a 9A39M1 reloader, and the 9S18 Kupol detection radar. Later reporting from Defense Express documented additional Russian Kupol-family losses, including a September 2025 Luhansk-region strike on a 9S18 Kupol target-acquisition radar and a November 2025 Donbas strike on a 9S18M1-3 radar station belonging to a Buk-M3 system.

Timeline
The documented timeline is concentrated in the full-scale invasion phase, when Ukrainian drone and special-operations strikes repeatedly targeted Russian air-defense vehicles. The clearest dated appearance is August 30, 2023, when Ukrainian reporting placed a Russian 9S18 Kupol near Svatove alongside a Buk system and a 9K37 launcher-loader.
A second Luhansk-region strike was reported on September 7, 2025, when Defense Express said Ukrainian special operations forces destroyed a 9S18 Kupol target-acquisition radar, a Buk surface-to-air missile system, and a 9K37 launcher-loader. On November 17, 2025, Defense Express and NV reported that HUR's Prymari unit had struck a 9S18M1-3 radar station from a Buk-M3 system among several Russian air-defense assets in the temporarily occupied Donbas.

Operational role
In the conflict record, the 9S18 appears as a Russian radar component of Buk-family air-defense batteries rather than as a standalone launcher. GlobalSecurity describes the 9S18 Kupol as a Soviet and Russian station for detection and target designation in the 9K37 Buk air-defense missile system, transmitting air-situation information to the 9S470 command post. It also lists later 9S18M1 and 9S18M1-3 variants used with Buk-M1, Buk-M1-2, and Buk-M2E-related configurations.
The incident reports fit that system role. The Svatove and 2025 Luhansk reports both place the Kupol with other Buk-family vehicles, while the November 2025 Donbas report identifies the 9S18M1-3 as the radar station of a Buk-M3 system. The supported conflict role is therefore air-defense surveillance, target detection, and target-designation support for Russian Buk-family units operating in Ukraine.
