Direct proof of use
Direct conflict-use evidence for the 30N6 family in the 2014 Russia-Ukraine War comes from S-300 radar loss lists, a transfer record, and later visual loss documentation. Oryx lists Russian losses of 5N63S Flap Lid B engagement and tracking radars of the S-300, while its Ukrainian loss list records 5N63S Flap Lid B radars for S-300PS and 5N63-1 Flap Lid A radars for S-300PT.
Ukraine also received a Slovak S-300 package during the full-scale invasion. The U.S. Defense Department recorded Slovakia's April 2022 decision to supply an S-300 air-defense system to Ukraine, and Oryx's Slovakia delivery list identifies a 5N63S Flap Lid B radar for S-300PMU among the transferred radar equipment.

Timeline
The clearest dated transfer milestone is April 2022, when Slovakia supplied Ukraine with an S-300 air-defense system and later open-source tracking identified a 5N63S Flap Lid B radar as part of the Slovak package.
By May 2026, a later Russian loss was documented in two separate forms: Ukrainian reporting cited the 15th Artillery Reconnaissance Brigade's footage of a Russian 5N63S radar station being detected and destroyed, and WarSpotting cataloged a destroyed Russian 5N63S target-acquisition radar for a 75R6 S-300PS battery uploaded on May 24, 2026.

Operational role
The radar's role in the conflict was tied to S-300-family air defense rather than independent attack. Open technical references describe 30N6/5N63S Flap Lid variants as engagement, target-tracking, illumination, and missile-guidance radars for S-300P, S-300PS, and export S-300PMU-family batteries.
The documented Russian and Ukrainian entries therefore show the radar as a fire-control component within long-range surface-to-air missile units. Loss records do not by themselves prove individual missile engagements, but they do directly place Flap Lid-family radars in Russian and Ukrainian S-300 service during the war.
