Direct proof of use
Russian forces used P-800 Oniks missiles in the 2014 Russia-Ukraine War as Bastion-launched land-attack weapons from occupied Crimea. Ukrainian military-attributed reporting identified three Oniks missiles striking the Odesa airport runway on 30 April 2022, and later Ukrainian Air Force reporting identified repeated July 2023 salvos from Bastion coastal missile systems in Crimea.
The documented use is distinct from simple possession or deployment: the cited records describe missiles fired from Crimea and striking or being launched toward targets in Odesa Oblast and southern Ukraine.

Timeline
The first source-backed Oniks strike in this record is the 30 April 2022 attack on Odesa airport's runway. In July 2023, after Russia left the Black Sea grain deal, Ukrainian and regional reporting described multiple Oniks salvos against Odesa and southern Ukraine, including six Oniks missiles on 18-19 July, seven on 19-20 July, and five more on 22-23 July.
Later 2023 reporting tied Oniks launches to attacks on Odesa-region facilities and port infrastructure, with Southern Defense Forces statements cited for Bastion launches from occupied Crimea and damage to grain storage.

Narrative
Oniks is an anti-ship cruise missile, but Russia's wartime use in this conflict has been documented as land attack from coastal Bastion systems. The pattern in the cited sources centers on southern Ukraine, especially Odesa and the Black Sea port network, rather than naval engagements.
Ukrainian Air Force spokesperson Yurii Ihnat attributed the difficulty of countering Oniks to its high speed and low terminal flight profile. That context helps explain why Ukrainian reports often list Oniks separately from Kalibr, Kh-22, Iskander, and Shahed attacks in mixed strike packages.
