ROKS Dokdo

ROKS Dokdo (LPH-6111) is the lead ship of the Dokdo-class amphibious assault ship of the Republic of Korea Navy, launched on 12 July 2005 at the shipyard of Hanjin Heavy Industries & Constructions Co. in Busan. ROKS Dokdo was the flagship of the Fifth Component Flotilla of the Korean Navy until the launch of ROKS Marado in 2018. Previously, this title was held by the 9,000-ton at-sea Underway Replenishment (UNREP) support vessel ROKS Cheonji.

Naming
The name Dokdo comes from the Korean name for the Liancourt Rocks, a group of islets in the Donghae that are currently administered by South Korea. The islets' ownership is disputed between Japan and South Korea. The Japanese Ministry of Foreign Affairs expressed its regret over the naming of Dokdo.

ROKS Dokdo was commissioned into the ROK Navy on 3 July 2007.

History
In March 2010, Dokdo assisted in search and rescue operations after the sinking of ROKS Cheonan. In July, the ship took part in Operation Invincible Spirit, a joint alliance exercise.
