Ukraine has been making increasing use of underwater suicide drones to make up for its lack of navy and target Russian naval ships in the Black sea. On 24/05, the Ivan Kurs was targeted by such USV, although Russia claimed its counter-measure proved effective. On 04/08, the landing ship Olenegorsky Gornyak was damaged in the port of Novorossiysk by one such drone.

This question resolves YES if a ship operated by the Russian Navy is damaged by Ukraine by 30/09. Cases were a ship was attacked but damage is not proven would not count. The attack doesn't have to be done by USVs.
