Direct proof of use
The clearest public conflict-use record for a Vishnya-class ship in the 2014 Russia-Ukraine War is the June 11, 2023 Priazovye incident in the Black Sea. Reuters reporting republished by MarineLink said Russia stated that Ukraine tried to attack the Black Sea Fleet ship with six high-speed drone boats while Priazovye was patrolling major natural-gas pipelines.
Daily Sabah, citing Russian Defense Ministry statements and agency reporting, identified Priazovye as a reconnaissance vessel and said it was carrying out monitoring and security along the TurkStream and Blue Stream pipeline routes in the southeastern Black Sea. The same report said the claimed attack occurred about 300 kilometers southeast of Sevastopol and that Ukrainian officials did not immediately comment.

Narrative
Priazovye's documented wartime role fits the Vishnya class's intelligence-collection design. KCHF identifies Priazovye as a Project 864 intelligence ship and describes the class as purpose-built for SIGINT and COMINT electronic intelligence using sensors and satellite communications, with short-range self-defense weapons.
In the Russia-Ukraine War context, the ship appears in public reporting as a Russian Black Sea Fleet surveillance and force-protection platform rather than as a strike combatant. Foreign Policy Research Institute analysis described the Black Sea Fleet's wartime mission set as expanding toward protection and detection tasks, including efforts to protect or monitor critical infrastructure such as the TurkStream and Blue Stream pipelines; it specifically connected Priazovye's targeting to one of those monitoring missions.
The available open-source record does not independently verify damage to Priazovye or the destruction of the attacking craft. The direct-use claim supported here is narrower: Russia fielded Priazovye in the conflict for Black Sea monitoring and infrastructure-security duty, and public reporting tied that mission to the June 2023 Ukrainian uncrewed-boat attack claim.
