Ukrainian corvette Chernihiv

Izmail was assigned to the 5th separate Balaklava brigade of border patrol ships of the Western Central Committee of the KGB of the USSR. The flag of the Naval Border Troops was raised on the ship on 17 February 1981. The corvette participated in the protection of the state border, the economic zone of the USSR and fishing off the coast of the Crimean peninsula in the Black Sea. From 1981 to 1989 the vessel served in the army for 1,053 days. Izmail inspected 5,459 vessels, detained 296 of them, including 14 foreign schooners. Twice, on 10 March 1986, and 12 February 1988, as part of the KUG, together with ships of the Black Sea Fleet, the corvette took part in the expulsion from territorial waters a detachment of US Navy warships (cruiser USS Yorktown and destroyer USS Caron).

In April 1986, as part of the PSKR group (Izmail, MG-7, MPK-105), while searching for a foreign transmitter in the area of Cape Tarkhankut, the vessel established contact with an unidentified submarine (as it later became known TCG Yıldıray) and accompanied the sub for 22 hours. Komsomolets of Georgia and Kyiv Komsomolets accompanied the boat to the Port of Eregli.[3][4]

In June 1992, he became a member of the Naval Units of the State Border Protection Committee of Ukraine, where the corvette also actively participated in the protection of the state border. In February 1992, the ship detained the first Turkish schooner, Chinakchi-Oğulları, which poached flounder in the Ukrainian economic zone. Until 1996, Izmail repeatedly participated in operations against foreign poachers.

At the end of 1995, a decision was made at the governmental level to transfer the Project 1124P ships to the Ukrainian Navy by the State Border Guard Service of Ukraine. In January 1996, Izmail together with the Dnipro were transferred to the Ukrainian Navy. The ships were accepted in a satisfactory technical condition: given the specifics of the maritime border service, the ships rarely used sonar equipment, mine and torpedo weapons. Only the mechanical running gear and the armament of the missile and artillery combat unit were actively used.

The Ukrainian naval flag was hoisted on the ship on 19 January 1996. The ship was reclassified into a corvette and renamed Chernihiv. The change of the ship's name was agreed with the Chernihiv City Administration, whose representatives arrived in Sevastopol on 19 January to congratulate the sailors on raising the battle flag. The consecration of the flag of Chernihiv took place on the same day on the feast of the Epiphany.[4] For some time, both border and naval crews were on the ship. Officers, midshipmen and sailors for the Chernihiv crew were recruited from various ships, as well as from other types of retrained Armed Forces.

Due to lack of funding and the impossibility of dock repairs, the Chernihiv was excluded from the fleet and written off in 2005. Before the ship was written off, the name Izmail was returned, and the name Chernihiv was given to the minesweeper of the Project 266M.[5] The corvette was sold as scrap ferrous and non-ferrous metals of OJSC MetProm.[6] In April 2010, she sank while dismantling a hull in Lake Donuzlav.[7]
