Kommuna is a submarine salvage ship in service with the Russian Navy's Black Sea Fleet. A double-hulled catamaran, she was laid down at the Putilov Factory (now the Kirov Factory) in St. Petersburg in November 1912 as Volkhov. The ship was launched the following year, and commissioned on 14 July 1915. She was renamed Kommuna on 31 December 1922. Kommuna has served in the Russian Imperial, Soviet, and Russian Federation navies through the Russian Revolution and two World Wars.

In 1967, the ship sailed from the Baltic to the Black Sea, and was refitted to carry submersibles. In 1974 she was equipped with a Type AS-6 Poisk-2 submersible, which on 15 December 1974 made a record dive to a depth of 2026 metres.

In 1984 the ship was laid up for transfer to the Russian Academy of Sciences. However, the transfer was cancelled, and she was thoroughly looted, and had to be completely refitted before returning to Naval service. 01 July 1999 she was re-designated from "salvage ship" to "rescue ship".

The Kommuna has raised over 150 vessels in total, but submarines are not the ship’s only business. In 1977, it salvaged a sunken Su-24 aircraft.

In October 2009 she received a British-built submarine rescue submersible Pantera Plus, capable of operating to depths of up to 1000 metres.

At present moment, the Komunna rescue ship is the oldest vessel of the Russian Navy.

Now in service.
