The Ukrainian Armed Forces probably attacked the Admiral Grigorovich frigate of the Russian Black Sea Fleet — ISW

According to the Institute for the Study of War, footage on social networks shows an unknown number of unmanned surface vehicles that allegedly struck at least one Grigorovich-class frigate.

In addition, the volunteer group "GeoConfirmed" reports that one of the videos shows attacks on the Admiral Grigorovich-class frigate which is matched only by the Admiral Makarov ship in the Russian Black Sea Fleet. This coincides with the ISW data, which reported that the vessel is a carrier of Kalibr missiles.

Ukraine has not yet commented on the situation.
