Dokdo-class amphibious assault ship

The Dokdo-class Amphibious Assault Ship is a class of Landing Platform Helicopter (LPH) amphibious assault ships operated by the Republic of Korea Navy. Designed by Hanjin Heavy Industries, the requirements for the amphibious landing ships were to enhance Korea's current amphibious operation capability, both in terms of assault and military operations other than war (MOOTW) type operations.

The ROK Navy required a versatile landing ship with amphibious capabilities in its program to build a blue-water navy. In the end Hanjin's Dokdo design was chosen for this need. LSF-II 631-also built by Hanjin- was chosen as the LCAC to operate from the ship.

Ships in Class

The Dokdo Class of LPH are named after islands deemed important or symbolic to the ROK Navy. Three ships were planned at first, but the third ship was cancelled during the period of Lee Myung-bak government.

ROKS Dokdo (LPH-6111) is named after the Liancourt Rocks, which are called "Dokdo" in Korean but "Takeshima" in Japanese. Although the South Korean Coast Guard took control of the isles in 1954, Japan still disputes the sovereignty of the rocks.

The second unit, the ROKS Marado, is named after Marado Island, commonly thought of as being both the ending and beginning point of Korea. Today a monument stands there recognizing it as the southernmost point of the country. This ship was cancelled once, but the budget was restored in 2012. A ski ramp for operations of V/STOL jet fighters is being considered for Marado.

The third unit was to be named after Baengnyeong Island, which is located in the Yellow Sea near the disputed Northern Limit Line (NLL) with North Korea. Baekryeong Island is the territory administered by South Korea that is closest to the NLL. It was an important military base and the site of fierce combat during the Korean War.
