Chungmugong Yi Sun-sin-class destroyer

Chungmugong Yi Sun-sin class destroyers (Korean: 충무공 이순신급 구축함, Hanja: 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 Sunsin, was launched in May 2002 and commissioned in December 2003. Chungmugong Yi Sun-sin-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.

Weapon Systems

The ships have 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.

The electronics suite includes one Raytheon AN/SPS-49(V)5 2D long-range radar (LRR), one Thales Nederland MW08 target indication 3D 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 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.[1]

Anti-piracy measures in Somalia

Piracy in Somalia has been a threat to international shipping since the second phase of the civil war in Somalia in the early 21st century. Since 2005, many international organizations have expressed concern over the rise in acts of piracy. Piracy impeded the delivery of shipments and increased shipping expenses, costing an estimated $6.6 to $6.9 billion a year in global trade in 2011 according to Oceans Beyond Piracy (OBP). According to the German Institute for Economic Research (DIW), a veritable industry of profiteers also arose around the piracy. Insurance companies significantly increased their profits from the pirate attacks, as the firms hiked rate premiums in response. Since 2013, piracy attacks have reduced in the region due mostly to patrolling by the navies of countries across the world, especially India, China and EU Navfor Operation Atalanta (a joint operation of numerous European navies).

Dokdo-class amphibious assault ship

The Dokdo-class amphibious assault ship (Hangul: 독도급 강습상륙함, Hanja: 獨島級強襲上陸艦) is a class of Landing Platform Helicopter (LPH) amphibious assault ships operated by the Republic of Korea Navy (ROKN). Designed by Hanjin Heavy Industries, the requirements for the amphibious landing ships were to enhance South Korea's current amphibious operation capability, both in terms of assault and military operations other than war (MOOTW) type operations.

Go of Balhae

Dae Joyeong (대조영; 大祚榮; [tae.dʑo.jʌŋ] or [tae] [tɕo.jʌŋ]; died 719), also known as King Go (고왕; 高王; [ko.waŋ]), established the state of Balhae, reigning from 699 to 719.

Guided missile destroyer

A guided-missile destroyer is a destroyer designed to launch guided missiles. Many are also equipped to carry out anti-submarine, anti-air, and anti-surface operations. The NATO standard designation for these vessels is DDG. Nations vary in their use of destroyer D designation in their hull pennant numbering, either prefixing or dropping it altogether. The U.S. Navy has adopted the classification DDG in the American hull classification system.

In addition to the guns, a guided-missile destroyer is usually equipped with two large missile magazines, usually in vertical-launch cells. Some guided-missile destroyers contain powerful radar systems, such as the United States’ Aegis Combat System, and may be adopted for use in an anti-missile or ballistic-missile defense role. This is especially true of navies that no longer operate cruisers, so other vessels must be adopted to fill in the gap.

Gwanggaeto the Great-class destroyer

The Gwanggaeto the Great-class destroyers (Hangul: 광개토대왕급 구축함, Hanja: 廣開土大王級 驅逐艦), often called KD-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.

Hong Sang Eo

The Hong Sang Eo (Red Shark) torpedo (Hangul: 홍상어 어뢰), also called the K-ASROC, is a vertically launched anti-submarine missile successively developed and tested by South Korea's University of Science and Technology, the Korea Agency for Defense Development (ADD) and the Republic of Korea Navy in 2009. The Red Shark missile has a range of 12 miles (19 km) and carries a K745 Blue Shark torpedo that is deployed by parachute near the intended target. After release, the Blue Shark independently searches for the target.

The missiles are planned to be deployed on KDX-II and KDX-III destroyers starting in 2010. Each destroyer will carry between 8 (KDX-II) and 16 (KDX-III) of the missiles. The development cost of the program was around US$ 80 million, with a production cost of about $14 million. They were designed in order to combat the potential threat of North Korean submarines.


Hyunmoo-3 is a new cruise missile that is to be fielded with the military of Republic of Korea. It is designed by Agency for Defense Development (ADD). The name Hyunmoo (Hangul: 현무) comes from a mythical beast described as the "Guardian of the Northern Sky", perhaps hinting North Korea.

KDDX-class destroyer

KDDX-class destroyer (KDX-IV) is a stealthy destroyer class under development by Daewoo Shipbuilding & Marine Engineering for ROK Navy, to be launched after 2025. Displacement of the class is set to be about 8,000 tons, length 155 meters, breadth 18.8 meters and draft 9.5 meters. Will feature KVLS to launch Hyunmoo-3C land attack cruise missiles and SSM-700K anti ship tactical cruise missiles. At 8000 tons displacement, it will be lighter than Sejong the Great-class destroyers, but with more advanced sensors and stealth characteristics and lower operating costs. The ships will have advanced missile defense. The size of this new destroyer will be between that of the currently operating 4,200-ton KDX-II and the Aegis Destroyer KDX-III, and will be assigned to a naval task force.

ROKS Choe Yeong (DDH-981)

ROKS Choe Yeong (DDH-981) (Korean: 최영, Hanja: 崔瑩) is a Chungmugong Yi Sun-sin-class destroyer in the South Korean navy. The ship is named after the 14th century Korean general Choe Yeong. She is a Chungmugong Yi Sun-sin-class destroyer and entered service in 2006.

In January 2011 she saw action when she pursued a chemical tanker captured by Somali pirates. The tanker was retaken with eight pirates killed and five captured. Later in 2011 she evacuated South Korean nationals stranded in Libya.

ROKS Chungmugong Yi Sun-sin (DDH-975)

ROKS Chungmugong Yi Sun-sin (DDH-975) is a Chungmugong Yi Sun-sin-class destroyer in the Republic of Korea Navy. She is named after the Korean commander Yi Sun-sin.

ROKS Munmu the Great (DDH-976)

ROKS Munmu the Great (DDH-976) is a Chungmugong Yi Sun-sin-class destroyer in the South Korean navy. It was named after the Korean king Munmu of Silla.

Sejong the Great-class destroyer

The Sejong the Great-class destroyers (Sejongdaewang-Geup Guchukam or Hangul: 세종대왕급 구축함, Hanja: 世宗大王級驅逐艦), also known as KD-III, are three guided missile destroyers of the Republic of Korea Navy (ROKN). The second ship was commissioned in August 2010 and the third in August 2012. As at 2013, the ROKN has deployed three ships with an option for three more; in December 2013 the option to acquire the second three was taken up.

Sinking of MV Sewol

The sinking of MV Sewol (Korean: 세월호 침몰 사고; Hanja: 世越號沈沒事故), also called the Sewol ferry disaster, occurred on the morning of 16 April 2014, when the passenger/ro-ro ferry was en route from Incheon towards Jeju in South Korea. The 6,825-ton vessel sent a distress signal from about 2.7 kilometres (1.7 mi) north of Byeongpungdo at 08:58 KST (23:58 UTC, 15 April 2014). Out of 476 passengers and crew, 304 died in the disaster, most notably around 250 students from Danwon High School (Ansan City). Of the approximately 172 survivors, more than half were rescued by fishing boats and other commercial vessels that arrived at the scene approximately 40 minutes after the Korea Coast Guard.The sinking of MV Sewol resulted in widespread social and political reaction within South Korea. Many criticized the actions of the captain and most of the crew. Also criticized were the ferry operator and the regulators who oversaw its operations, along with the administration of President Park Geun-hye for its disaster response (including the poor showing of the coast guard) and attempts to downplay government culpability.On 15 May 2014, the captain and three crew members were charged with murder, while the other eleven members of the crew were indicted for abandoning the ship. An arrest warrant was also issued for Yoo Byung-eun, the owner of Chonghaejin Marine, which operated Sewol, but he could not be found despite a nationwide manhunt. On 22 July 2014, police revealed that they had established that a dead man found in a field 415 kilometres south of Seoul was Yoo.

Stealth ship

A stealth ship is a ship which employs stealth technology construction techniques in an effort to ensure that it is harder to detect by one or more of radar, visual, sonar, and infrared methods.

These techniques borrow from stealth aircraft technology, although some aspects such as wake and acoustic signature reduction (Acoustic quieting) are unique to stealth ships' design. Though radar cross-section (RCS) reduction is a fairly new concept many other forms of masking a ship have existed for centuries or even millennia.

Tomb of Munmu of Silla

Tomb of Munmu of Silla is an underwater tomb, the 30th king of Silla, in Gyeongju, North Gyeongsang Province, South Korea. This is Historic Site No. 158, also known as Daewang-am.
