ROKS Cheonghaejin (ASR-21) is the only ship of the Cheonghaejin-class submarine rescue ship in the Republic of Korea Navy. She is named after the military headquarter, Cheonghaejin.^[1]

Her operations include rescuing trapped sailors in submarines, naval operation support for submarines, underwater research and mapping support, and recovery of sunk vessels. It is equipped with a deep submergence rescue vehicle (DSRV) that operates up to 500 metres (1,600 ft), and a rescue chamber that holds up to nine people.

Once all nine Son Wonil-class submarines are delivered to the Republic of Korea Navy, another ASR ship of the same class is planned to be built.

ROKS Cheonghaejin was launched on 18 October 1995 by Daewoo Shipbuilding and commissioned on 2 December 1996.^[2]

She salvaged a North Korean Yugo-class submarine in 1998.

She salvaged Chamsuri-class patrol boat #357 that was sunk during the naval clash in 2002 with North Korea.
