Kommuna

Kommuna is a catamaran submarine salvage ship currently serving in the Russian Navy's Black Sea Fleet. Launched in 1913, she is the oldest active-duty naval vessel in the world. Her primary role is the recovery of sunken submarines and deep-sea rescue operations.

Originally named Volkhov, the ship was built by the Putilov Shipyard and entered service with the Imperial Russian Navy in 1915. She served through World War I, the Russian Revolution, and World War II, during which she raised numerous sunken vessels and submarines. Renamed Kommuna in 1922, she underwent several refits over her long career, including being equipped to carry modern deep-submergence rescue vehicles. She remains operational in the Black Sea, recently being deployed following the sinking of the cruiser Moskva in 2022.
