porte-hélicoptères d'assaut sud coréen

[Davout]

Il ne faut pas oublier que le Japon est un archipel et qu'il dépend de l'étranger pour ses ressources (il faut bien sécuriser ses routes maritimes) d'où la prédominance de la marine au sein de ses forces armées.

Pour la Corée, j'imagine qu'il y a bien la protection de ses routes maritimes pour son approvisionnement en matières premières également mais il y a aussi la Corée du Nord (bien que sa marine soit ridicule) et aussi une certaine méfiance vis-à-vis du Japon.

Enfin, pour le Japon et la Corée du Sud il y a la montée en puissance de la Chine...

Jeu subtil d'équilibre des forces, ces pays (Corée et Japon) ont une longue tradition maritime et c'est un juste retour des choses. Quant au retour de l'impérialisme nippon c'est fort peu probable car l'archipel s'est occidentalisé et la tradition guerrière affaiblie.....

DESIGN

The lead ship of the class, DOKDO began construction in early 2003 at the Hanjin Heavy Industries & Constructions Co in Busan it was the largest amphibious warfare ship built in Asia at the time, surpassing the Japanese Osumi-class dock landing ships. At 18,860 tons fully loaded, 200m long and 32m wide DOKDO’s design is loosely based on the USN’s WASP class amphibious assault ships, with inclinded sides to reduce radar return, a flight deck and a aft well deck that can launch landing craft. Just over two years later DOKDO was launched on 8 July 2005. For the next two years DOKDO fitted out and conducted extensive sea and helicopter trials, before her 2007 commissioning. The lessons learned with DOKDO have been incorperated into her sister ship MARADA, which is due for completion in 2010. A third ship BAEKNYENDO is under construction and is believed to be a modified version of the class, expected to be larger at 20 000 tons and built with VSTOL aircraft capability. If so, when commissioned in 2011 BAEKNYENDO could be viewed as the ROKN’s first aircraft carrier.

The DOKDO class was designed to operate as the flagship with large command and control (C2) suites to command either an amphibious task force, or of a rapid response fleet with the new KDX-11 and KDX-111 class destroyers, FFX frigates, and KSS submarines, as well as function as a command post in civil emergencies ie; natural disasters.

DOKDO was named after South Korea’s easternmost islets (which Korea and Japan are in a diplomatic fight over) in the East Sea.

CREW

The 426 Officers and men that make up the ship’s company of DOKDO are accomodated in high standard berthing areas on ship. Officers, Senior enlisted and Junior ratings have their own mess and recreation areas onboard. A command staff of 150 is also embarked. Well equipped medical facilities, as well as a dentist are onboard.

COMMAND AND CONTROL

As a flagship, DOKDO is outfitted with an advanced Command, Control,

Communications, Computers, Intelligence, Surveillance, Targeting, Acquisition and

Reconnaissance (C41STAR) system in a joint venture by Samsung and Thales Corporation. It includes theatre battle management core system, connecting DOKDO’s sensors and radars giving the ship the overall operational picture on the sea, ground, or in the air.

SENSORS

With DOKDO’s command and control functions, the ship’s sensor suite a multi-level affair. The ship’s communications suite (both external and internal communications systems such as VLF/HF, VHF, UHF, SHF and INMARSAT) is built by Unimo Technology, while the L-3 Integrated Platform Management/Integrated Bridge systems were a joint project by MAPPS/Samsung.

Radar

For air search, KODKO and her sister ships are equipped with the Thales Nederland SMART-L (Signaal Multi-beam Acquisition Radar for Targeting, L-band) 3D radar and the MW.08 air/surface search radar. The SMART-L has a range of up to 400 km and can detect up to 1000 targets at once. The MW.08 can track up to 10 surface and 20 air targets simultaneously up to 150 kilometres. DOKDO is also equipped with an SPS-95K surface/search navigation radar.

Electronic Warfare (EW)

The Electronic Warfare suite is an intergrated platform including the SLQ-260X TACM torpedo counter-measure system, the Thales Naval Nederland SIRIUS Infrared Search and Tracking system, and the EADS Dagaie Mk2 chaff launcher systems, along with other systems.

WEAPONS

With the expectation that DOKDO would be part of a task force during future missions, it was decided that the ship needed a small weapons suite for self defence.

DOKDO was commissioned with 2 SGE-30 Goalkeeper Close In Weapons System. Equipped with an track-while-scan radar fire-control system, Goalkeeper uses the GAU-8A 30-mm seven-barreled gatling gun able to output a maximum rate of fire of 4,200-rounds a minute. The class is only the second non US navy to be armed with a single 21-cell RIM-116 Rolling Airframe Missile (RAM) launcher located on top of the bridge. The RAM missile has a range of 10 kilometres and a speed of Mach 2. The class has provisions for weapons upgrades.

With no Anti-Surface Warfare nor Anti-Submarine Warfare capabilities DOKDO’s protection will be placed on her escorts. With her aviation ability, DOKDO could embark both Anti-Submarine and/or Attack Helicopters to assist the escorts in dealing with such threats.

POWER PLANT

DOKDO is powered by four Doosan Heavy Industries/MAN Man Diesel SA PC2.5 STC medium speed diesel engines. Driving two variable pitch propellers, they move the ship at speeds up to 22 plus knots. DOKDO is also equipped with Bow thrusters which assist the ship at low speed.

AMPHIBIOUS OPERATIONS

DOKDO can carry up to 720 Troops. With the expectation of the troops only embarking for short to medium times, they are embarked in basic conditions onboard, but still have a high standard mess area. With the ship built for their use, the passageways, hatches, and stairwells are big enough to allow a fully kitted troops free and easy movement from their accommidations onboard, to the troop embarkation areas at the well deck at the stern of the boat, and/or the flight deck.

The ship can carry 31 armoured vehicles or 35 trucks, but if necessary, the hanger bay can be used to increase the vehicle capacity to 70 tanks or 200 trucks.

Air operations

With its large flight deck DOKDO can handle every type of helicopters currently serving in the South Korean Armed Forces. But the ROK military has only a limited amount of helicopters, which ensures that DOKDO is not operating to full capacity. It is hoped that new helicopters are purchased in the near future. The flight deck itself has five helicopter landing spots, two elevators, and is coast with a special urethane similar to the coating on the flight deck of the US aircraft carriers. This coasting is resistant to heat, allowing the possiblitiy of VSTOL aircraft operations. The hanger bay can hold up to ten helicopters. The air capability allows DOKDO to insert Troops/Special Forces further inland.

Landing Operations

DOKDO has a large well deck (floodable dock) that can operate either two LCACs (large hovercraft), four LCM-8 or six LCU Mk10 landing craft at a time. The LCAC’s are based on the US versions and can carry up to 60 tons and 25 troops and have a top speed of 35 knots. The LCM-8 landing craft can carry 57 tons at 9.2 knots. The LCU Mk10 landing craft can carry 30 tons at 11 knots. With the well deck DOKDO can wait off-shore and launch her landing craft within sight of the beach but in deep water, free to maneouver if attacked.
