Project 697TB is a Soviet-built inshore minesweeper class based on small fishing trawler hulls and designed to search for, sweep, and destroy mines in naval raid zones, coastal waters, and dispersed basing areas. RT-59 was transferred from the Caspian Flotilla to the Black Sea Fleet in July 2023.
Project 697TB minesweepers are tied to the Russo-Ukrainian War through Russian redeployment: RT-59 was reported transferred from the Caspian Flotilla to the Black Sea Fleet in July 2023; Russian Dnieper Flotilla planning reporting also listed 697TB minesweepers as potential assets. I found no confirmed public report identifying a Project 697TB vessel as struck or sunk.
