Project 10750 Sapfir / Lida-class inshore minesweeper

Project 10750 Sapfir, known to NATO as the Lida class, is a Soviet and Russian inshore minesweeper class built for mine clearance in ports, harbor approaches, and river channels. The design uses a fiberglass hull, mine-search sonar, and a light gun-and-MANPADS fit, while RT-233 saw Russian fleet transfers linked to the Russia-Ukraine War.

Conflict Usage

Project 10750 Lida-class minesweepers are tied to the Russo-Ukrainian War through Russian force movement: RT-233 was reported transferred from the Caspian Flotilla to the Black Sea Fleet in 2023, and Russian Dnieper Flotilla planning reporting listed Project 10750 vessels among minesweeper assets suitable for the Dnieper theater. I found no confirmed combat damage or loss event for this class.
