Design and construction.
The s, including "Cushing"/"Sloviansk", were constructed in Bollinger Shipyards, Lockport, Louisiana. Members of the class have an overall length of . They have a beam of and, at the time of construction, a draft of . The patrol boats have a displacement of at full load and at half load. They are powered by two Paxman Valenta 16 CM diesel engines or two Caterpillar 3516 diesel engines. They have two 3304T diesel generators made by Caterpillar; these can serve as motor–generators. Their hulls are constructed from highly strong steel, and the superstructure and major deck are constructed from aluminium.
The Island-class patrol boats have maximum sustained speeds of . They are fitted with satellite navigation systems, collision avoidance systems, surface radar, and a Loran C system. They have a range of and an endurance of five days. Their complement is sixteen (two officers and fourteen crew members). Island-class patrol boats are based on Vosper Thornycroft patrol boats and have similar dimensions.
In U.S. service, "Cushing" was fitted with one machine gun and two M60 light machine guns; it could also be fitted with two Browning .50 caliber machine guns. In Ukrainian service, "Sloviansk" was armed with a Soviet-era 110-PM autocannon.
Service history.
United States Coast Guard.
"Cushing" was commissioned on Coast Guard Day, 4 August 1988, named after Cushing Island, located near Portland, Maine. Throughout her service life, she would partake in a number of humanitarian and military operations. "Cushing" primarily supported the United States Coast Guard's search and rescue, law enforcement, living marine resources, and counter drug and illegal migrant missions in the Gulf of Mexico, Caribbean Sea, and the Atlantic. "Cushing" was homeported in Alabama, Puerto Rico, and North Carolina during her Coast Guard service. 
"Cushing" was involved in Operation Uphold Democracy, the American backed military intervention in Haiti following the 1991 Haitian coup d'état. In 1994, "Cushing" was among the 55 Coast Guard cutters operating in support of Operation Able Manner and Operation Able Vigil. These patrols consisted of border security operations, and resulted in the rescue and repatriation of over 63,000 Haitian and Cuban migrants. This was the largest United States Coast Guard operation since the Vietnam War. 
"Cushing" was later transferred to Atlantic Beach, North Carolina, where her primary focus was fisheries and marine law enforcement, as well as search and rescue. 
On 8 March 2017 "Cushing" was decommissioned along with USCGC "Nantucket" in North Carolina. Two s replaced both cutters the following year. "Cushing" was laid up in the Coast Guard Yard near Baltimore, Maryland.

Ukrainian Naval Forces.
In September 2018, Ukraine was selected to receive the "Cushing", as well as her sister ship "Drummond" through the United States Navy International Programs Office, as part of military aid to the country. The Island-class patrol boat was the first major commissioned ship built in the United States operated by the Ukrainian Navy, which up to this point was composed largely of ships inherited from the breakup of the Soviet Black Sea Fleet into the Russian Black Sea Fleet and the Ukrainian Navy. As a result, the two ships were brought out of storage, and received maintenance and equipment upgrades. "Cushing" and "Drummond" were transported to the Black Sea port city of Odesa aboard the "Ocean Freedom" dry cargo ship, arriving on 21 October 2019. 
In Ukrainian service, "Cushing" was renamed to "Sloviansk", in memory of the home town of sailors Roman Napriagila and Sergiy Mayboroda and was subordinate to the 30th Surface Ships Division.
Sinking.
On 3 March 2022, during the Russian invasion of Ukraine, "Sloviansk" was conducting reconnaissance and patrol missions around the port cities of Odesa, Chornomorsk and Yuzhne. During this period, the vessel was reportedly sunk by a Russian Kh-31 anti-ship missile. The fate of the crew has not been reported.
