Dokdo-class amphibious assault ship
This article contains promotional content. (May 2020) |
The Dokdo-class amphibious assault ship (독도급 대형수송함; 獨島級 大型輸送艦) is a class of landing platform helicopter (LPH) and amphibious assault ships operated by the Republic of Korea Navy (ROKN). It was designed and built by Hanjin Heavy Industries (HHIC) to enhance South Korea's amphibious operation capability in terms of assault and military operations other than war (MOOTW).

Development
editThe ROK Navy required a landing ship with amphibious capabilities in its program to build a blue-water navy which was met by the Dokdo design. The Solgae-class LCAC — made by HHIC — was selected as the landing craft air cushion (LCAC) to operate from the ship.[5]
Specifications

The LPX is an amphibious warfare ship with a well deck to accommodate amphibious assault vehicles (AAVs) and two LCACs, the first of which (LSF 631) was acquired in April 2007. The ship is 199 meters (652 ft 11 in) long, 31 meters (101 ft 8 in) wide, with a 14,000-ton (empty) or 18,000-ton (full) displacement, and was built incorporating stealth technologies.
As a high-speed amphibious ship, the LPX was based on the concept of "over-the-horizon assault." The idea comprises a military operation in which an amphibious landing is conducted with high-speed air-cushioned vehicles and helicopters from beyond the horizon, where the enemy cannot easily detect or attack them. 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 has a carrying limit of 720 marines (+300 crew members), ten tanks, ten trucks, 7 AAVs, three field artillery pieces, and two LCAC hovercraft. It can also carry ten helicopters when no ground vehicles are on its hangar deck.[6]
The flight surface is also sprayed with urethane, which can support VTOL aircraft. South Korea is considering the purchase of F-35B fighters to operate from its Dokdo-class ships.[7][needs update] Currently, the LPX operates mainly UH-1H and UH-60P. However, both are designed for land‐based operations and lack abilities for ship-borne operations, such as protection against damage from salty breezes, making them challenging 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][needs update]
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 pre-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 could 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] However, as of December 2022, no such plans have been officially declared.
