Hyundai Heavy Industries (HHI) completed and launched the world's third, and Korea's first, 7,600-ton class Aegis destroyer.

The launching ceremony for the ship was held May 25th, 2007. In attendance were President Roh Mu-hyun, First Lady Kwon Yang-sook, Minister of Defense Kim Jang-soo, Chief of Naval Operations Song Young-moo, Chairman of the Korean Joint Chiefs of Staff Kim Kwan-jin, commissioner of the Defense Acquisition Program Administration Lee Sun-hee, Mayor of Ulsan Park Maeng-woo, CEO of HHI Choi Kil-seon, and 350 other guests at HHI's Special and Naval Shipbuilding Yard in Ulsan, Korea.

The destroyer was named Sejongdaewang-Ham after the legendary king of the Chosun Dynasty who strived to protect his people and his kingdom by fortifying that nation's defenses. After naval operational tests are completed the destroyer will be delivered by the end of 2008 and deployed by the Korean Navy.

South Korea started to design and build the Aegis destroyer in November, 2004. Construction of the ship took 2 and a half years to complete. South Korea is the third country with an Aegis destroyer, joining both the U.S. and Japan.

The Sejongdaewang-Ham is the first KDX-III destroyer in the Korean Navy. It will help strengthen Korean naval operational power, along with the six 4,300-ton class KDX-II destroyers.

The Sejongdaewang-Ham is equipped with an AEGIS combat system, which includes the SPY-1D (V) radar, capable of detecting and tracking 1000 targets and attacking 20 of those targets simultaneously.

The destroyer also has a wide-ranging anti-aircraft defense system, ground operations support, and can automatically track both guided and ballistic missiles or enemy fighter planes. It is expected to be the flagship of the Korean Navy.

The destroyer's computer systems have been localized, including the weapons system controlling the perpendicular missile launcher, anti-warship missiles, and torpedoes; the electronic warfare equipment, and the sailing radar.

The destroyer's Stealth technology minimizes electromagnetic waves, infra-red rays, and underwater noise, helping to prevent detection by the enemy. It is equipped with a chemical warfare protection facility and an automated damage recovery system.

Sejongdaewang-Ham is so advanced that HHI utilized the most recent technological developments from its research institutes, the defense industry, the Navy, and the academic community.

Since constructing and delivering the first Korean-built frigate in 1980, HHI has grown as a developer and builder of naval ships; a leader in the design development and building of frigates, submarines, destroyers, and the 7000-ton class KDX-III AEGIS destroyer. HHI has also exported various naval ships to overseas markets such as New Zealand, Bangladesh and Venezuela.

The word 'Aegis' comes from the name of the mythological protective shield of Zeus. It was first used by the U.S. Navy as a name for an advanced missile under development in 1969. Since that time the U.S. Navy has called any highly protective warfare system an Aegis Combat System and destroyers equipped with the Aegis Combat System are called Aegis destroyers. The ships equipped with the Aegis Combat System in Spain and Norway are convoys, not destroyers.

Dokdo class landing platform experimental

The LPX project was the Republic of Korea Navy's new amphibious landing ship project for which Hanjin Heavy Industries has provided the general design package. The ROK Navy's requirements for the new 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.

On 12 July 2005, Dokdo (LPH 6111), the lead ship of her class, was launched at the shipyard of Hanjin Heavy Industries & Constructions Co. in Busan. The ship was named after the Dokdo islets in the Sea of Japan (East Sea). She is scheduled to be handed over to the South Korean Navy in 2007.

The first air cushion landing craft (LSF 631) of LSF-II project will be delivered for Dokdo in April, 2007.

Length: 199 m
Beam: 31 m
Draught: 7 m
Speed: 23 knots (max), 18 knots cruising
Ship complement: 300
Ship armament: Two Goalkeeper CIWS, One RIM-116 Rolling Airframe Missile

Troops: 720 marines, 6 tanks, 7 amphibious assault vehicles, 10 trucks

Chungmugong Yi Sun-sin class destroyers

Chungmugong Yi Sun-sin class destroyers, also known as KDX-II class destroyers are multipurpose destroyers of the Republic of Korea Navy. The first ship of this class, ROKS Chungmugong Yi Sunshin, was launched in May 2002 and declared operational in December 2003. KDX-II class destroyer is the second phase of the Republic of Korea Navy's substantial shipbuilding program, KDX, which plans to help turn it into a blue-water navy from a coastal defence force.

Weapon Systems

The ship has a 32-cell strike-length Mk 41 VLS for SM-2 Block IIIA area-air defence missiles, one 21-round RAM inner-layer defence missile launcher, one 30 mm Goalkeeper close-in weapon system, one Mk 45 Mod 4 127 mm gun, eight Harpoon anti-ship missiles and two triple 324 mm anti-submarine torpedo tubes.

Electronics suite includes one Raytheon AN/SPS-49(V)5 2D long-range radar (LRR), one Thales Nederland MW08 3D target indication radar (TIR), two Thales Nederland STIR240 fire-control radars with OT-134A Continuous Wave Illumination (CWI) transmitters, an SLQ-200(V)K SONATA electronic warfare system and a KDCOM-II combat management system which is derived from the Royal Navy Type 23 frigate's SSCS combat management system. BAE Systems WDS Mk 14 originally developed for the US Navy's New Threat Upgrade evaluates threats, prioritizes them, and engages them in order with SM-2.

On the 4th unit ROKS Wang Geon the 32-cell Mk 41 VLS is moved to the left and an indigenous VLS for a 'Korean VLA' is installed on the right. The ship's forward part is spacious enough to take a 64-cell Mk 41 VLS.

General Characteristics

Length: 150 m
Beam: 17 m
Propulsion: CODOG
Speed: 30 knots (56 km/h)
Crew Complement: 200

La Corée du Nord lance un nouveau bateau lance-missiles et teste un SLBM bien amélioré pour celui-ci dans l'espoir de remplacer son ancien bateau Romeo et ses missiles de 1re génération. On pense que le nouveau bateau transporte 3x oiseaux par opposition à 1 ou 2 pour l'ancien bateau. Le dernier missile défilé cette année est censé augmenter la portée du seul missile déployé confirmé de 500 km jusqu'à 2500 km pour ce nouveau Mk5 (voir photos)
