The Dokdo-class amphibious assault ship (Template:Lang-ko, Hanja: 獨島級 大型輸送艦) is a class of landing platform helicopter (LPH) amphibious assault ships operated by the Republic of Korea Navy (ROKN). Designed by Hanjin Heavy Industries (HHIC), the requirements for the amphibious landing ships were to enhance South Korea's amphibious operation capability, both in terms of assault and military operations other than war (MOOTW).

Development

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. The Solgae-class LCAC—also built by HHIC— was chosen as the landing craft air cushion (LCAC) to operate from the ship.[5]

Specifications

The LPX is an amphibious warfare ship which includes a well deck to accommodate amphibious assault vehicles (AAVs) and two LCAC, the first of which (LSF 631) was acquired in April 2007. The ship is 199 metres (652 ft 11 in) long, 31 metres (101 ft 8 in) wide, with a 14,000-ton (empty), or 18,000-ton (full) displacement and was built incorporating stealth technologies. It has been said to be one of the most advanced vessels in the Asian Pacific.[5]

As a high-speed amphibious ship, the 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 is conducted with high-speed air-cushioned vehicles and helicopters from beyond the horizon, where they cannot be easily detected or attacked by the enemy. The conventional landing ship tank (LST) 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, and two LCAC hovercraft capable of landing on enemy shores doing 40 knots (74 km/h; 46 mph)—a mix that enables it to launch troop landings from both sea and air. She can also carry 10 helicopters when there are no ground vehicles on her hangar deck.[6]

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.[7] Currently, the LPX operates mainly UH-1H and UH-60P. However, both of these are designed for land‐based operations and lack abilities for ship-borne operations such as protection against damage from salty breezes making them difficult to operate on-board continuously.[8] The KUH-Amphibious, the sea-based amphibious variant of the KAI Surion, is now under development. Production is planned to commence in late 2015 with some 40 helicopters planned.[9]

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 a per-set price of 13,000,000,000 won (roughly $15,000,000).

The second ship of the class, Marado, was built with some changes compared to Dokdo. The flight deck is adapted to accommodate two V-22 Ospreys, while Dokdo was able to only carry one. In place of the Thales SMART-L multibeam radar and MW08 surveillance radar, Marado uses the Elta Systems EL/M-2248 MF-STAR multifunction surveillance radar and LIG Nex1 SPS-550K 3-D air and surface surveillance radar. It also has a different weapons suite than the 30 mm Goalkeeper and RAM, instead using two 20 mm Phalanx CIWS and having a K-VLS at the rear of the superstructure for the locally developed K-SAAM.[10][11][12]

Dokdo is similar in size to the light aircraft carriers derived from the Sea Control Ship such as the Spanish Navy's former aircraft carrier Príncipe de Asturias and the Royal Thai Navy's Chakri Naruebet.

Some proposed uses for the ship include UN peacekeeping operations and disaster relief.

The Korean news agency Yonhap reported in December 2017 that the Korean military was considering operating F-35B aircraft from the Dokdo-class amphibious assault ships.[13][14]

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 Dokdo class, 2 Sejong the Great class, 4 Chungmugong Yi Sun-sin class, 1 Gwanggaeto the Great class, and possibly a number of Incheon-class frigates and 2 or 3 Type 214 submarines.
