The Pride of Goryeo Dynasty: DDH-981 ROKS Choi Young


DDH-981 ROKS Choi Young a.k.a Choe Yeong was part of the second batch of Chungmugong Yi Sunshin class destroyers that were delivered to the Republic of Korea Navy. She was built by Hyundai Heavy Industries and was launched on 20 October 2006, entering service on 4 September 2008. She is bestowed from Choe Yeong, the General of Goryeo Dynasty. She is about 150 metres (490 ft) long, 17 metres (56 ft) wide and displaces between 4,800 and 5,000 tons. Her propulsion unit is a CODOG unit, capable of propelling her at speeds of up to 30 knots (35 mph). She has a crew complement of 200. Her armament consists of a 32-cell VLS (with space to install a 64-cell system), a Mk 45 gun, a RAM launcher, a Goalkeeper CIWS and eight Harpoon anti-ship missiles. Other systems include an AN/SPS-49 radar, an MW08 radar, and a DSQ-23 sonar.

The Choe Yeong was assigned to patrol the Northern Limit Line in November 2009 after a boundary dispute clash with North Korea, the first of its kind in seven years. In August 2010, the ship participated in a series of naval drills in the Yellow Sea, four months after the sinking of the PCC-772 ROKS Cheonan of Pohang-class Corvette.

On 15 January 2011, the Norwegian-owned chemical tanker Samho Jewelry was captured by Somali pirates while en route from the United Arab Emirates to Sri Lanka. The South Korean operator of the vessel, the Samho Shipping Company, was facing huge losses because it was obligated to continue paying Norwegian investors under its charter even while the vessel was held by pirates. However, the Norwegian government had no military presence in the area at the time. Eight South Koreans were among the 21 crewmembers being held hostage.

The South Korean government dispatched the Choe Yeong, under Captain Cho Young-joo, commander of the Cheonghae Anti-piracy Unit The Choe Yeong pursued the Samho Jewelry for nearly a week until the pirates aboard the tanker were fatigued. Several fake attacks were staged to exhaust the pirate crew. When some of the pirates left the ship to attempt another hijacking on a nearby Mongolian vessel, commandos from the Republic of Korea Naval Special Warfare Brigade boarded the Samho Jewelry while a Westland Lynx helicopter provided covering fire. Communications jamming was utilized to prevent the pirates from calling for assistance. The tanker was retaken with eight pirates killed and five captured. The captain of the Samho Jewelry survived a gunshot wound to the stomach while three navy personnel suffered "light scratches". The rest of the tanker crew were unharmed.

The Choe Yeong escorted the Samho Jewelry to Oman, where they docked at the port of Muscat on 31 January. The rescue was called "a perfect military operation" by Lieutenant General Lee Sung-ho of the Joint Chiefs of Staff of the Republic of Korea.

The ROKS Choe Yeong was diverted from anti-piracy operations in the waters off of Somalia to evacuate South Korean nationals stranded in Libya. The Choe Yeong successfully evacuated 32 South Korean nationals on 4 March and docked in the Maltese port of Valletta. The Choe Yeong will remain on standby near Libyan waters to support "further evacuation efforts."


Some biography about DDH-976: ROKS Munmu the Great


DDH-976 ROKS Munmu the Great is a Chungmugong Yi Sunshin-class destroyer in the South Korean navy. It was bestowed from the 30th Silla Dynasty Monarch; 1st King of the Unified Silla Dynasty, Munmu the Great a.k.a Kim Beop-min. This ship is launched in April 11th 2003, commissioned in September 30th 2004 and currently active in service, as of 2013.

ROKS Munmu the Great is one of the Chungmugong Yi Sunshin-class destroyers that involved in the Cheonghae Anti-Piracy Unit to curb piracy in the Gulf of Aden. That means the majority vessels for Cheonghae Anti-Piracy Unit are coming from the Chungmugong Yi Sunshin-class destroyers.

ROKS Munmu the Great was the first ship to be deployed as part of the unit to Somali waters on March 13, 2009. On April 17, it deterred pirates from boarding the cargo vessel Puma, which was registered in Denmark.On May 4, the Munmu the Great responded to a distress call by the North Korean merchant vessel Dabaksol. A Westland Lynx military helicopter was launched to protect the Dabaksol until the pirates had fled. The North Korean sailors thanked the members of the unit before proceeding to India. A member of the Joint Chiefs of Staff of the Republic of Korea stated, "This is the first time that the South Korean navy has rescued a North Korean cargo ship from a pirate’s attack. According to the international law of the sea, we should help all vessels regardless of their nationality."

Admiral's Choice, Chungmugong Yi Sunshin Class Destroyers: The Lead Ship, DDH-975 ROKS Chungmugong Yi Sunshin


Chungmugong Yi Sunshin class destroyers (Chungmugong Yi Sunshin-geup Guchuk-ham; Hangul/Hanja: 충무공 이순신급 구축함/忠武公李舜臣級驅逐艦) are multipurpose destroyers of the Republic of Korea Navy. The lead ship of this class, ROKS Chungmugong Yi Sunshin, was launched in May 2002 and commissioned in December 2003. The namesake of this class is bestowed from Chungmugong Yi Sunshin, the Joseonese Admiral who saved Korea-Joseon Dynasty from invading Toyotomi Hideyoshi's Japan Forces during the Imjin Invasion (1592-1598).

Chungmugong Yi Sunshin class destroyers were the second class of ships to be produced in the Republic of Korea Navy's destroyer mass-production program named Korean Destroyer eXperimental, which paved the way for the navy to become a blue-water navy. Six ships were launched by Hyundai Heavy Industries and Daewoo Shipbuilding & Marine Engineering in four years.

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, DDH-978 ROKS Wang Geon, the 32-cell Mk 41 VLS is moved to the left and an indigenous VLS named K-VLS is installed on the right. The ship's forward part is spacious enough to take a 64-cell Mk 41 VLS.

The KDX-II is part of a much larger build up program aimed at turning the ROKN into a blue-water navy. It is said to be the first stealthy major combatant in the ROKN and was designed to significantly increase the ROKN's capabilities.

First Korean-Made Destroyer Helicopter, King Gwanggaeto the Great Class: The Lead Ship, DDH-971 ROKS King Gwanggaeto the Great


The King Gwanggaeto the Great class destroyers (GwanggaetoDaewang-geup Guchuk-ham; Hangul/Hanja: 광개토대왕급 구축함/廣開土大王級驅逐艦), often called KDX-I class, are destroyers, but are classified by some as frigates, operated by the Republic of Korea Navy. It was the first phase of ROKN's KDX program, in moving the ROK Navy from a coastal defence force to a blue-water navy. The namesake of this class bestowed from King Gwanggaeto the Great, the 19th King of Goguryeo Dynasty who expanded Goguryeo Kingdom to nowadays Yanbian Korean Autonomous Province, People's Republic of China and Primorsky Krai, Russia.

The KDX-I was designed to replace the old destroyers in the ROKN that was transferred from the US Navy in the 1950s and 1960s. It was thought to be a major turning point for the ROKN in that the launching of the first KDX-I meant that ROKN finally had a capability to project power far from it shores. After the launching of the ship there was a massive boom in South Korean international participation against piracy and military operations other than war.

The primary weapon deployed by King Gwanggaeto the Great class vessels is the Super Lynx helicopter, which acts in concert with shipboard sensors to seek out and destroy submarines at long distances from the ships. The Gwanggaeto-class also carries a close-in anti-submarine weapon in the form of the Mark 46 torpedoes, launched from triple torpedo tubes in launcher compartments either side of the forward end of the helicopter hangar. A secondary anti-shipping role is supported by the RGM-84 Harpoon surface-to-surface missile, mounted in two quadruple launch tubes at the main deck level between the funnel and the helicopter hangar. For anti-aircraft self-defense the Gwanggaeto-class carries 16 RIM-7P Sea Sparrow. The Gwanggaeto-class also carries two 30mm Goalkeeper to provide a shipboard point-defense against incoming anti-ship missiles and aircraft. The main gun on the forecastle is an OTO Melara 127 gun.

The Gwanggaeto the Great class is powered by two General Electric LM2500-30 gas turbines and two SsangYong 20V 956 TB 82 diesel engines. The Gwanggaeto-class can reach a maximum speed of 30 knots.

All King Gwanggaeto the Great class destroyers were built by the Daewoo Heavy Industries Co., Inc. (now as Daewoo Shipbuilding and Marine Engineering) at Gohyeon-dong, Geoje, Southern Gyeongsang Province, South Korea. In 1989, Daewoo Heavy Industries began working on the 4,000-ton destroyer which is now secondary destroyer of the Korean navy, and the achievement was made through DSME's 100% design engineering for the first time in Korea.

Korean made AEGIS based Destroyer, King Sejong the Great Class: The Lead Ship, DDG-991 ROKS King Sejong the Great


The King Sejong the Great class destroyers (Sejongdaewang-geup Guchuk-ham or Hangul/Hanja: 세종대왕급 구축함/世宗大王級驅逐艦), also known as KDX-III, are guided missile destroyers of the Republic of Korea Navy. The lead ship was launched 25 May 2007, sponsored by Kwon Yang-sook, the First Lady of the Republic of Korea; the wife of the Late President Roh Moo-hyun at the time and was commissioned in December 2008. The second ship was commissioned in August 2010. As of 2010, the ROK Navy has committed itself to deploy three ships with an option for three more.

On April 20, 2007, Chief of Naval Operations of the Republic of Korea Navy announced that the lead ship of KDX-III class destroyers will be referred as the Sejong the Great. Sejong the Great (Hangul/Hanja: 세종대왕/世宗大王) is the fourth king of the Joseon Dynasty of Korea. He is credited with the creation of the Korean alphabet, Hangul. The ship features the Aegis combat system (Baseline 7 Phase 1) combined with AN/SPY-1D multi-function radar antennae.

The King Sejong the Great class is the third phase of the Republic of Korea Navy's Korean Destroyer eXperimental (KDX) program, a substantial shipbuilding program, which is geared toward enhancing ROKN's ability to successfully defend the maritime areas around Korea from various modes of threats as well as becoming a blue-water navy. At 8,500 tons standard displacement and 11,000 tons full load, the KDX-III Sejong the Great destroyers are by far the largest destroyers in the Republic of Korea Navy, and built slightly bulkier and heavier than Arleigh Burke class destroyers or Atago class destroyers to accommodate 32 more missiles. KDX-III are currently the largest surface warfare ships to carry the Aegis combat system.

King Sejong the Great class destroyers' main gun is the 127mm/L62 Mk. 45 Mod 4 naval gun, an improved version of the same gun used on other warships from several foreign nations. Point-defense armaments include one 30 mm Goalkeeper CIWS and a RIM-116 Rolling Airframe Missile Block 1 21-round launcher, the first Aegis platform to carry RAM. Anti-aircraft armament consists of SM-2 Block IIIA and IIIB in 80-cell VLS. Anti-Submarine Warfare armaments consists of both K-ASROC Hong Sang-eo (Red Shark) anti-submarine rockets and 32 K745 LW Cheong Sang-eo (Blue Shark) torpedoes. Anti-ship capability is provided by 16 SSM-700K Hae Seong (Sea Star) long-range anti-ship missile, each with performance similar to the U.S. Harpoon. Land-attack capability is provided by the recently-developed Hyunmoo IIIC (Guardian of the Northern Sky) cruise missile, which is similar to the U.S. Tomahawk.

King Sejong the Great class destroyers' are often compared to Arleigh Burke class and Atago class because they utilize the AN/SPY-1 multi-function radar, have similar propulsion and capabilities. One notable difference between the Sejong the Great-class ships and Burkes is the number of VLS cells. Destroyers of the Sejong the Great class will have a capacity of 128 missiles, as opposed to 96 on the Arleigh Burke class (although ships in the Arleigh Burke class has the capability to quad-pack 4 ESSM missiles into one launch cell, greatly increasing armament) and the Japanese Atago class destroyers. The Sejong the Great class is thus one of the most heavily armed ship in the world second only to Kirov class battlecruiser with 352 missiles. Another similarity to Arleigh Burke class Flight IIA and Atago class destroyers is the presence of full facilities for two helicopters, a feature missing from earlier Arleigh Burke and Kongō class destroyers.

Three of these destroyers have, according to South Korean news agency Chosun Ilbo, the capability to "track and monitor any missile launched from anywhere from the North." This capability was demonstrated by the tracking of a North Korean Missile in April 2009.
