They are trying to hide big ships, so we are going after the smaller ones,“We are going to keep hunting.” June 6, Ukrainian USV penetrated into Pankse Lake, an almost totally-landlocked bay on northwestern shore of the Crimean Peninsula, rammed and destroyed a Russian naval tugboat.
Also special ops teams, an elite Ukrainian naval strike group, used MAGURA kamikaze sea drones run down, ram & sink two Russian KC-701 Tunets-class patrol cutters operating near Kerch Strait. 

The Russian warships’ mission had been, in part, to prevent or block Ukrainian USV attacks in the area and against targets further north. Russia’s most serious single naval loss of the war took place on April 14, 2022, a pair of Ukrainian anti-ship missiles sank the BSF flagship, cruiser Moskva. Ukraine has sunk roughly a third of BSF warships. To most military analysts, Ukraine scored another major naval victory in September 2023 with a series of missile and drone strikes targeting BSF main base at Sevastopol, attacks over a period of almost 3-weeks ended with one heavy assault ship sunk, one missile submarine destroyed, at least 1 heavy assault ship damaged. Russian navy most part abandoned Sevastopol in Oct – for the first time since 1941.

Russian spoken at that time said submarine, the Rostov-Na-Danu, was only moderately damaged and would quickly return to sea operations.
