The design for a submarine rescue ship was first offered for export as the DW 4000R Koje class. One ship of the design was ordered in 1992 to support the Republic of Korea Navy (ROKN)'s submarine fleet. The vessel is capable of providing battery charging, provisions, fuel, oxygen and water to ROKN submarines.Шаблон:Sfn The ship measured Шаблон:Convert long with a beam of Шаблон:Convert and a draught of Шаблон:Convert.Шаблон:Sfn At full load, the ship displaces Шаблон:Convert. The vessel is powered by a diesel-electric system comprising four MAN Burmeister & Wain 16 V 28/32 diesel engines creating Шаблон:Convert each and two electric motors, creating Шаблон:Cvt.Шаблон:Sfn These power the two shafts with controllable pitch propellers, three bow thrusters and two stern thrusters.Шаблон:Sfn This gives the ship a maximum speed of Шаблон:Convert and a range of Шаблон:Convert at Шаблон:Convert. The vessel is also equipped with shaped rudders and a dynamic positioning system which all the ship to better maneuver at low speeds. The ship has a crew of 130 personnel.Шаблон:Sfn

The submarine rescue ship is equipped with two 2,000 kW shaft generators and four 400 kW diesel generator sets that create a total of 5,600 kW of electric power. These are used to power two electrohydraulic telescoping cranes at the fore and an A-frame crane on the stern used to handle the assigned deep submergence vehicle (DSRV).Шаблон:SfnШаблон:Sfn The initial DSRV was capable of operating to a depth of Шаблон:Cvt.Шаблон:Sfn However, a new DSRV was assigned to the Cheonghaejin class in November 2008. DSAR-5 is capable of operating up to Шаблон:Cvt. The DSRV measures Шаблон:Cvt long with a beam of Шаблон:Cvt and a draught of Шаблон:Cvt and has a crew of three. The DSRV can transport up to 16 people.Шаблон:Sfn Additional capabilities include a diving bell capable of transporting nine people and a decompression chamber.Шаблон:Sfn The Cheonghaejin class has a towing winch and carries two landing craft vehicle personnel on davits for use as work boats.Шаблон:Sfn The ship has hull-mounted sonar and a landing platform for a light helicopter.
