The Dokdo Class: an LHD for the ROK
Australia isn’t the only Pacific Rim country looking to modernize its Navy these days. China’s rapid shipbuilding program and work on its aircraft carrier project gets a lot of attention – but just to the east, South Korea is fielding its own AEGIS-equipped “air warfare destroyer,” while picking up new capabilities via a new class of amphibious assault LHD ship. Sound familiar? Hobart and Canberra Class, meet the KDX-III King Sejong Class AEGIS destroyer (launched May 2007) and the new “LPH” Dokdo Class LHD (commissioned July 2007).
The 199-meter, 18,860-ton Dokdo Class officially has the less aggressive designation of LPH (landing platform, helicopter), but its well deck and amphibious assault capabilities place it within the LHD category…
The Dokdo Class/ LPX
The Dokdo Class can carry up to 720 troops, plus a mix of helicopters, tanks/armored vehicles, and wheeled vehicles. Transport to shore is accomplished via landing ships or LCAC hovercraft. The Dokdo Class is only 2/3 the size of Australia’s new Canberra Class, and just over 1/3 the size of the USA’s Wasp Class; but Dokdo is the largest ship in the South Korean Navy.
For defense, they will rely on a combat system from the Samsung Thales Corp. joint venture. It will rely on Thales’ SMART-L long range 3 dimension search radar, with a detection and tracking range of 400 km/ 240 miles. For defensive responses, it can coordinate a SeaRAM guided missile system, 2 Thales “Goalkeeper” 30mm CIWS systems, and various decoying systems. Even so, support from Korea’s frigate-sized KDX-II destroyers and new KDX-III King Sejong Class AEGIS destroyers will be essential.
There has been media speculation that the Dokdo Class is in fact a light aircraft carrier, citing the ability to install a ski jump and operate V/STOL Harriers or STOVL F-35B Lightnings from its deck. America’s 42,000 ton Wasp Class LHDs are used in this manner, and it would be possible from Australia’s Canberra Class LHDs as well.
The smaller size of the Dokdo Class, however, means that using the ship in this way doesn’t make much sense. It would get one very few fighters, while sacrificing most of the ship’s total carrying capacity. Fighter aircraft require a lot of space below-decks, and so does their fuel and weapons storage. South Korea’s prime focus remains North Korea, and aerial cover for amphibious operations a la Inchon can easily be supported from land bases. Meanwhile, international operations featuring Korean LHDs would need Korean helicopters far more than they’d need Korean fighters.
Circumstances can change; but Korea’s Ministry of Defence has stated that they have no plans to operate fighter aircraft from these ships, and military logic makes this a believable assertion. This is not to say that offensive fixed wing aircraft will never operate from Dokdo. It’s just that they’re far more likely to be UAVs akin to the MQ-9 Reaper, rather than supersonic fighters.
LPX: Future Plans for the Class
The Dokdo Class ship ROKS Marado was scheduled to enter service by 2010, but its budget was canceled. That budget was restored in 2012, and recent regional tensions are making high-end ships like LHDs and Aegis destroyers more attractive to Korea. Marado commemorates a small southern island that is commonly thought of as both the ending and beginning point of Korea, depending on one’s perspective.
Up to 4 ships of class were originally planned, but doctrine has shifted toward 2-3 “rapid response fleets,” each built around 1 Dokdo Class ship and a number of destroyers. If there’s a 3rd ship of class, previous plans involved naming it after Baengnyeong Island, which is located in the Yellow Sea near the disputed Northern Limit Line (NLL) with North Korea.
Contracts and Key Events
April 13/09: Samsung Thales Corp’s senior vice president, Byun Seung-wan, is quoted by Defense News as saying that Dokdo’s combat system is drawing regional interest:
“Southeast Asian countries have shown interest in one developed for the… Dokdo…. About two years ago, STC completed the five-year Landing Platform Experimental (LPX) combat system, in cooperation with the ADD, based on expertise gathered from its development of combat systems for the South Korean Navy’s KDX-I/II destroyers, frigates and patrol ships…. STC was the prime contractor for the integration and development of the command support and the command and fire-control system.”
The article also traces STC’s growth as a global developer of naval and land combat and battlefield management systems.
July 3/07: The ROKS Dokdo is handed over to the Navy in a ceremony. KOIS report.
Note that the name Dokdo is politically significant, referring to a set of islands whose territorial claim is disputed with Japan. The Korean perspective on Dokdo/Takeshima may be found here. Unsurprisingly, Japan filed a diplomatic protest over the name back in 2005. Asian countries tend to have civilization confidence, however, and the Korean reply was rude.
