Project 1840 is the name of a Soviet diesel-electric research submarine design of which only one vessel was built. The design is known in the west by its NATO reporting name Lima. The submarine, which was assigned hull number БС-555 (БС, большая специальная or bolshaya spetsialnaya, meaning large special), was completed in 1979, and used by the Black Sea Fleet. It was decommissioned and laid up in 1994. The unarmed vessel was equipped with two diving chambers for deep-sea operations and hydro-acoustic experiments.
