The Project 09852 ‘Belgorod’ nuclear-powered special submarine has been developed on the base of the Project 949A (Oscar-II) nuclear-powered cruise missile submarine by the Central Design Bureau for Marine Engineering Rubin (a subsidiary of the United Shipbuilding Corporation).

According to the open sources, the new underwater combatant is intended for the Navy`s Main Department of Deep-Water Researches (GUGI). Some specialists suggest that the submarine is designed for various scientific deep-water missions, search-and-rescue operations, installation and checking of underwater hardware, tests of scientific equipment, and monitoring of underwater transport lines.

Project 09852 submarine is believed to carry the Poseidon unmanned underwater vehicles (UUVs) and other UUVs. According to the open sources, the Project 09852 submarine has a full displacement of some 24,000 t and is 184 m long and 18.2 m wide. The ship produces an underwater speed of 33 knots.

The Belgorod K-329 submarine has a length of 184 m, a beam of 15 m, and a maximum displacement of 30,000 tones. She can reach a surface speed of 32 knots (59 km/h) and a depth of 500 to 520 m. She has a complement of 110 people.

The Belgorod can carry 6 Poseidon drone, an autonomous, nuclear-powered, and nuclear-armed unmanned underwater vehicle under development by Rubin Design Bureau, capable of delivering both conventional and nuclear payloads.
