ROKS Dokdo (LPH 6111) is the lead ship of the "LPX" class of amphibious landing ships of the Republic of Korea Navy, launched on 12 July 2005 at the shipyard of Hanjin Heavy Industries & Constructions Co. in Busan.

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 ROKS Dokdo is also the largest helicopter landing ship in Asia, with one of the fastest maximum speeds in the world in regards of heavy amphibious assault ships.

Specifications

The LPX is a versatile amphibious warfare ship, and includes a well deck to accommodate Amphibious Assault Vehicles (AAVs) and two Landing Craft Air Cushion (LCAC), the first of which (LSF 631) was acquired in April 2007. The ship is 199 metres long, 31 metres wide, with a 14,000 ton (empty), or 18,000 ton (full) displacement.

As a high-speed amphibious ship, LPX was based on the concept of "over-the-horizon assault." As the name indicates, the "over-the-horizon assault" comprises a military operation in which an amphibious landing operation is conducted with high-speed air-cushioned vehicles and helicopters from beyond the horizon, where they can't be easily detected or attacked by the enemy. The conventional LST (landing ship tank) has to approach the coastline for landing, at the risk of being fired upon by the enemy.

The LPX can carry 720 marines (+300 crew members), 10 tanks, 10 trucks, 7 AAVs, three field artillery pieces, 10 helicopters, and two LCAC hovercraft capable of landing on enemy shores doing 40 knots (74 km/h)—a mix that enables it to launch troop landings from both sea and air.

Self-defense armament includes the RIM-116 Rolling Airframe Missile system. The Goalkeeper Close-in weapon system (CIWS) was purchased in January 2003 from Thales, at per-set price of 13,000,000,000 won (roughly $15,000,000).

The flight surface is also sprayed with urethane, which can support VTOL jets, like Harriers. South Korea is considering the purchase of F-35B fighters to operate from its Dokdo class ships.[2] As an interim measure some Harriers may be purchased or leased from RAF surplus, as Harriers are operated by USMC in Okinawa training and logistics issues can be easily managed with US assistance, or even with the creation of a joint US-Korean-Japan Harrier squadron based in Okinawa.[citation needed]

Dokdo is similar in size to the Spanish Navy's current aircraft carrier SPS Príncipe de Asturias and the Thai Navy's HTMS Chakri Naruebet.

The Dokdo Class of LPH are named after Korean islands deemed important or symbolic to the ROK Navy. ROKS Dokdo (LPH-6111) is named after the Dokdo islets, a small group of islands under Korean administration.

The ROK Navy has plans to develop another similar ship by 2010. This unit will be named after Marado Island, which is located 11 kilometres offshore from Moseulpo harbor of Jeju. Marado Island is 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.

The third unit is 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.

Future plans

ROKS Dokdo (LPH 6111) conducts well deck operations with a US Navy LCAC.

Some proposed uses for the ship include UN peacekeeping operations and disaster relief. For this reason, the LP-X is expected to usher in a new era of expanded Korean naval activity, since it can be used for relief, transport, and other peacetime activities.

First Steps to a Blue Water Navy

In a speech delivered in March 2001, Kim Dae Jung stated that his administration was aiming to build a navy that "will defend the national interests in the five oceans and perform a role in defending world peace." By the year 2020, the ROK Navy plans to deploy two or three rapid response fleets, each comprising 1 LPX, 2 KDX-III, 4 KDX-II, 1 KDX-I and possibly a number of FFX frigates and two or three SSX submarines.
