Direct proof of use
The documented Project 773 Polnocny-C ship in Ukrainian service during the 2014 Russia-Ukraine War was Yuri Olefirenko, a Ukrainian Navy medium landing ship. Naval News identified Yuri Olefirenko as a Project 773 Polnocny-C landing ship and reported that drone footage showed it narrowly escaping a Russian artillery barrage near Ochakiv on June 3, 2022; the same article said later confirmation showed the ship was still operational.
Official Ukrainian sources provide additional direct support for wartime service. A June 23, 2022 presidential decree awarded the medium landing ship Yuri Olefirenko the honorary distinction For Courage and Bravery for the defense of Ukraine. A later presidential account of Cross of Military Merit awards described an artillery combat section from Yuri Olefirenko participating in repelling Russian aggression and engaging shore and air targets.

Narrative
Yuri Olefirenko entered the full-scale invasion as one of Ukraine's few larger surviving surface combatants. Naval News reported that the ship had been returned to Ukrainian custody after Russia's 2014 seizure of Crimea, escaped early 2022 claims of capture, and remained active about 100 days into the invasion.
In the conflict record, the ship's use was not only amphibious transport. The Ukrainian presidential account of the ship's decorated personnel specifically tied its artillery combat section to fire against shore and air targets, which supports the catalog role package of mobility-logistics, fire support, and air defense. The May 2023 Odesa reports should be treated as a Russian strike claim, not a confirmed loss, because the contemporary reporting emphasized that the assertion was unverified and not confirmed by Kyiv.
