It is reported that the Project 22160 patrol ship "Pavel Derzhavin" was attacked by a naval underwater drone in Sevastopol Bay, as a result of which it was damaged.
However, it is officially stated as follows:
“Scheduled mine and anti-sabotage defense exercises are being conducted at the roadstead of Sevastopol Bay,” the information support department of the Black Sea Fleet reported.
“During the exercises in Sevastopol, we worked out the tasks of searching and destroying sea floating mines and unmanned boats. The patrol ship Pavel Derzhavin and anti-sabotage boats were involved in the exercises, then they will return to their deployment point.”

By the way, this is why the stern of the ship is painted black.
