Vessels for the control of physical fields of Project 1806 are intended for measurement of acoustic, electromagnetic, electric, magnetic fields of surface ships and submarines. Until 1977 these units were classified by the USSR as hydroacoustic control vessels.

The vessel is intended for measuring the acoustic, electromagnetic, electric, magnetic fields of surface ships and submarines. The vessel was equipped with all kinds of equipment for measuring and controlling physical fields. For its power in the "Silence" mode, diesel generators placed in soundproofing cabins for the first time began to be used.

A total of 6 vessels for the control and measurement of the physical fields of the Project 1806 and 11 vessels of the physical fields of the Project 18061 were built.

Physical Fields Control Vessel SFP-322 laid down on 22 January 1985 at Shipyard named after A.M. Gorky, Zelenodolsk (yard No.304), launched on 15 February 1987, commissioned on 10 September 1987.

It was part of the MRSO division of the Black Sea Fleet, based on the Southern Bay, Sevastopol.

On 01.07.1997, SFP-322 was transferred to the Ukrainian Navy, with rename to Severodonetsk (hull number - U812). The vessel was not used for its intended purpose, being constantly at the berths.

On 20 March 2014, the Ukrainian flag was lowered and the Russian flag was raised on the vessel located in Sevastopol.

On 03 June 2014, the Severodonetsk physical field control vessel without identification flags was taken away by Russian tugboats from the Streletskaya Bay of Sevastopol for transfer to the Ukrainian side outside the 12-mile zone and its further towing to Ochakov.

The ship was decommissioned in 2019, and was cut into metal in the same year.
