On 3 March 2022 during the Russian invasion of Ukranian patrol boat Sloviansk, a former U.S. Coast Guard Island Class patrol boat was performing reconnaissance and protection missions for the ports of Odesa and to the south in the Black Sea when it was hit and sunk. Volodymyr Novatsky, mayor of the port city of Yuzhny, announced March 6 in a video posted to YouTube that the vessel had sunk and an unknown number of crew members were missing, including a resident of his town. Volodymyr Novatsky expressed condolences to the families of the sailors.
Known formerly as the Coast Guard cutter Cushing, Sloviansk was homeported in the Ukrainian city of Odessa along with the Starobilsk, formerly the U.S. Coast Guard patrol boat Drummond, which also was transferred to Ukraine in 2019. On 27 September 2018, ownership of Cushing and USCGC Drummond were formally transferred to Ukraine, after their retirement from the United States Coast Guard. The two vessels were shipped, as deck cargo, and arrived in Odessa on 21 October 2019.
The patrol vessel was renamed after the Donbass city Sloviansk. This name perpetuates the memory of the fallen defenders of Ukraine, natives of this city — sailor Roman Napriaglia, senior sailor Sergiy Mayboroda. Originally named USCGC Cushing was built at Bollinger Shipyards in Lockport, Louisiana, in early 1988 and commissioned on 4 August 1988, at Coast Guard Base Mobile, Alabama. She was homeported in Atlantic Beach, North Carolina. On 8 March 2017 Cushing was decommissioned along with USCGC Nantucket in North Carolina.Island-class patrol boats are based on Vosper Thornycroft 33-metre (108 ft) patrol boats and have similar dimensions.
