Direct proof of use
The P-18ML is documented in the 2014 Russia-Ukraine War through visually confirmed Ukrainian equipment-loss records from the full-scale Russian invasion. Oryx lists four Ukrainian P-18ML long-range VHF surveillance radars in its wartime loss record, two destroyed and two damaged, and states that its list includes only equipment for which photo or video evidence is available.
That evidence establishes Ukrainian fielding of the P-18ML in the conflict, but it does not by itself date each individual loss or identify the specific air-defense unit that operated each radar.

Timeline
The public record used here supports a broad full-scale-invasion timeframe rather than a precise first-use date. Oryx opened its Ukrainian equipment-loss record on February 24, 2022, and continues to update it as additional visual evidence becomes available.
Within that record, the P-18ML appears under Ukrainian radar and communications equipment. The listed outcomes, two destroyed and two damaged, show that the system was present in Ukrainian service in exposed battlefield or air-defense-network contexts during the war.

Operational role
The P-18ML's documented role in the conflict is air surveillance and air-defense support, not direct attack. Altimus-Tech describes the system as a ground-based long-range VHF surveillance radar and a modernized follow-on to the analogue P-18, with automatic tracking, data acquisition from other surveillance radars and height-finders, and data exchange over communication channels.
Those functions fit the compact conflict role assigned to the Ukrainian P-18ML row: air defense and reconnaissance/surveillance. The conflict-specific evidence confirms Ukrainian wartime use through visual loss documentation, while the manufacturer material explains why the system belongs to Ukraine's air-surveillance and air-defense sensor network.
