The Republic of Korea Navy (ROKN; Korean: 대한민국 해군), also known as the ROK Navy or South Korean navy, is the naval warfare service branch of the South Korean armed forces, responsible for naval and amphibious operations. The ROK Navy includes the Republic of Korea Marine Corps, which functions as a branch of the Navy. The ROK Navy has about 70,000 regular personnel including 29,000 Republic of Korea Marines. There are about 150 commissioned ships with the ROK Navy (a total displacement of about 215,000 tonnes). The naval aviation force consists of about 70 fixed-wing and rotary-wing aircraft. The ROK Marine Corps has about 300 tracked vehicles including assault amphibious vehicles.
The Republic of Korea Navy was established as the Marine Defense Group on November 11, 1945 after Korea was liberated from the Empire of Japan on August 15, 1945. Since the Korean War, the South Korean navy had concentrated its efforts on building naval forces to counteract the North Korean navy. As South Korea's economy grew, the ROK Navy was able to locally build larger and better equipped fleets to deter aggression, to protect the sea lines of communication, and to support the nation's foreign policy. As part of its mission, the ROK Navy has engaged in several peacekeeping operations since the turn of the 21st century. The ROK Navy aims to become a blue-water navy in the 2020s.

The main duties of the Navy shall be operations on the sea, including landing operations, and the main duties of the Marine Corps shall be landing operations, and the Navy and Marine Corps shall be formed and equipped for that purpose and shall provide education and training necessary therefor.— Act on the Organization of National Armed Forces
Korea has a long history of naval activity. In the late 4th century during the Three Kingdoms Period, Goguryeo defeated Baekje, fielding amphibious forces of 40,000 men in the process. In the 9th century, Commissioner Chang Bogo of Unified Silla established a maritime base called Cheonghaejin on an island to foster trading with China and Japan, and to eradicate pirates.
In 1380, naval forces of the Goryeo Dynasty defeated 500 invading Japanese pirate vessels by deploying shipboard guns, devised by Choi Moosun.This is reportedly the first use of shipboard guns in naval history. In 1389 and 1419, Korean naval forces invaded Tsushima Island to suppress Japanese piracy. In the early years of the Joseon Dynasty, the naval force reached its peak of 50,000 personnel, in order to combat the ongoing piracy issue.
During the Japanese invasions of Korea (1592–1598), the Korean naval force commanded by Admiral Yi Sunshin, who later became the head of the Navy, cut off the invaders' naval lifeline and defeated the Japanese fleet, reversing the war in favor of Joseon. Admiral Yi is also credited with the creation of the Turtle Ship.
By the end of the 19th century, the Joseon Navy had no significant naval force other than coastal defense fortresses. Although there was an attempt to modernize the navy by establishing a royal naval school, the Joseon Navy was brought to an end in 1895. In 1903, the government of the Korean Empire purchased its first modern war ship, KIS Yangmu. Korean naval tradition was disrupted after Korea was annexed by the Empire of Japan in 1910. During the Japanese occupation period, the Imperial Japanese Navy (IJN) built a considerable naval base - Chinkai Guard District in southern Korea (at present-day Jinhae).
The Republic of Korea Navy was established as the Marine Defense Group on November 11, 1945. After Korea was liberated from the Empire of Japan on August 15, 1945, Sohn Won-yil, a former merchant mariner and son of the Methodist minister and independence activist Sohn Jung-do, organized the Marine Defense Group in Seoul. The Group formed the Korean Coast Guard and Coast Guard Academy at Jinhae, and the Korean Coast Guard acquired 36 patrol boats (mainly ex-IJN and USN minecraft) through the United States Army Military Government in Korea. After the South Korean government government was established on August 15, 1948, the Korean Coast Guard became the Republic of Korea Navy, and Sohn was appointed as the first Chief of Naval Operations of the ROK Navy. On April 15, 1949, the Republic of Korea Marine Corps (ROKMC) was founded at Jinhae.
In October 1949, the ROK Navy purchased a 600-ton submarine chaser, the former USS PC-823 with funds raised among its personnel. She was renamed ROKS Baekdusan (PC 701) after Paektu Mountain, and became "the first significant warship of the newly independent nation".
The Korean War started with the North Korean army's surprise attack on Sunday, June 25, 1950. The ROK Navy confronted threats from the North Korean navy: "Perhaps the most aggressive and effective, if smallest, member of the South Korean armed services during the first year of the Korean War was the Republic of Korea Navy (ROKN). At the outset of the conflict, the 6,956-man ROKN, with  naval vessels of various types, was outnumbered by the 13,700 men and 110 naval vessels of the North Korean navy." With its UN allies, dominated by U.S. forces, the ROK Navy was able to gain control in the seas surrounding the country, as a task group of the UN Blockading and Escort Force (Task Force 95). On July 27, 1953, the three-year-long war was brought to an end when an armistice agreement was signed. During the war, Australia, Canada, Colombia, Philippines, France, the Netherlands, New Zealand, Thailand, the United Kingdom, and the United States contributed naval vessels as UN allies; Denmark sent the hospital ship Jutlandia. During the Korean War, the ROK Navy acquired 28 ex-USN ships including five Tacoma-class frigates.
In September 1953, the ROK Navy established the Republic of Korea Fleet, which was responsible for the operation and training of the ships.
After the Korean War, the ROK Navy built up its surface fleet with World War II-era warships loaned from the U.S. Navy. From 1955 to 1960, the ROK Navy acquired 42 ex-USN warships including two Cannon-class destroyer escorts. In May 1963, the ROK Navy acquired its first destroyer, ROKS Chungmu (DD 91), a Fletcher-class destroyer. Starting from 1972, nine former USN Allen M. Sumner-class and Gearing-class destroyers were transferred and added to the ROK Fleet inventory.
During the Vietnam War, the ROK Navy dispatched the Naval Transport Group ("Seagull"), and the Republic of Korea Marine Corps sent the 2nd Marine Brigade ("Blue Dragon") to South Vietnam. In April 1975, just before the Fall of Saigon, two ROKN LSTs evacuated about 1,300 South Koreans and South Vietnamese from South Vietnam to South Korea.
On July 30, 1960, ROKS Gangwon (DE 72), formerly USS Sutton (DE-771), sank the North Korean navy patrol craft PBS 371 off the coast of Geojin. On January 19, 1967, ROKS Dangpo (PCE 56), the former USS Marfa, was sunk by North Korean coastal artillery north of the demarcation line off the east coast of Korea. In June 1970, a Navy broadcast vessel (I 2) was captured and abducted by North Korean patrol craft in the vicinity of Yeonpyeong Islands in the West Sea (Yellow Sea).
In the 1970s, through the Park Chung-hee Administration's "Yulgok Plan" (an eight-year national defense plan "to build up self-reliant, national defense capability"), the ROK Navy began to establish a fleet of locally built warships. The Navy acquired shipbuilding capabilities by planning and building high-speed patrol craft such as Baekgu class and Chamsuri class in the 1970s - in November 1972, the ROK Navy launched its first domestically built fast patrol craft to intercept North Korean spy boats. The lead ship (FF 951) of the 2,000-ton Ulsan-class frigates was launched in 1980. The lead ship (PCC 751) of the 1,000-ton Donghae-class corvettes and the lead ship (PCC 756) of the updated Pohang-class corvettes were launched in 1982 and 1984 respectively. With local shipbuilders, the ROK Navy continued to carry out other shipbuilding programs for such as the Dolgorae-class midget submarine, Gojunbong-class tank landing ship, mine warfare ship (Wonsan-class minelayer, Ganggyeong-class minesweeper), Cheonji-class logistics support ship, and Cheonghaejin-class submarine rescue ship in the 1980s and 1990s.
In November 1987, the Headquarters Republic of Korea Marine Corps was re-established; it was disbanded in October 1973 due to budget constraint. In June 1993, the ROK Navy Headquarters was relocated from Seoul to the Gyeryongdae complex, the tri-service headquarters in Gyeryong.
Since the 1990s, the ROK Navy has been trying to build an ocean-going fleet to protect the sea lines of communication: In 1989, the Navy mentioned the "Strategic Task Fleet" (Jeollyak-gidong-hamdae) in the Joint Strategic Objectives Plan. The ROK Naval forces began to participated in RIMPAC exercise from 1990. During Admiral An Pyong-tae's tenure as CNO, President Kim Young-sam supported the Navy by approving a long-term shipbuilding plan for the ocean-going navy. In 1999, the Navy developed its strategic vision for the 2020s as "Navy Vision 2020" that outlined the Navy's future Task Fleet, which includes light aircraft carriers and ballistic missile submarines.
At the same time, the ROK Navy steadily upgraded its naval forces: In order to strengthen the surface combatants, the ROK Navy launched the lead ship (DDH 971) of the Kwanggaeto the Great-class destroyer in 1996 to replace the former USN destroyers. For building up a submarine force, the ROK Navy acquired its first submarine (other than midget submarines), ROKS Chang Bogo (SS 061), from Howaldtswerke-Deutsche Werft of Germany in 1992. In order to replace its antiquated S-2 Tracker anti-submarine warfare aircraft, South Korea purchased a squadron of P-3C Orion maritime patrol aircraft, which were delivered to the ROK Navy starting in 1995.
In October 1998, the ROK Navy hosted its first international fleet review in commemoration of the 50th anniversary of the Republic of Korea and its armed forces off coast of Busan and Jinhae.
In June 1999, the ROK Navy forces engaged the North Korea naval forces near the Northern Limit Line (NLL) in the vicinity of Yeonpyeong Islands. On June 29, 2002, the two Navies engaged again in the same vicinity resulting in the sinking of ROKS Chamsuri 357 (PKM 357).
In 2002, the lead ship (DDH 975) of the 5,500-ton Chungmugong Yi Sunshin-class destroyers was launched. In 2005, an 18,800-ton amphibious transport dock, ROKS Dokdo (LPH 6111) was launched. In 2006, the ROK Navy launched the lead ship (SS 072), which was named after the first Chief of Naval Operations, of the 1,800-ton Sohn Wonyil-class submarine equipped with an Air-Independent Propulsion (AIP) system. In May 2007, the ROK Navy launched the lead ship (DDG 991) of the 11,000-ton Sejong the Great-class destroyers, built around the American-made AEGIS combat system and the SPY-1D(v) multi-function phased array radar. In December 2008, the ROK Navy commissioned the fast missile craft ROKS Yoon Youngha (PKG 711), which was named after the skipper of ROKS Chamsuri 357.
From 2001 to 2003, a naval transport unit called Haeseong supported the Operation Enduring Freedom and the Sangnoksu Unit in East Timor. In 2005, the Navy dispatched a transport unit called Jejung to supply aid in humanitarian response to the 2004 Indian Ocean earthquake. The ROK Navy hosted its second international fleet review off coast of Busan in October 2008 to celebrate the 60th anniversary of the South Korean government.
On March 26, 2010, ROKS Cheonan (PCC 772), a Pohang-class corvette was sunk by a North Korean torpedo, resulting in death of 46 sailors near Baengnyeong Island, in the vicinity of the Northern Limit Line.
In preparation for an ocean-going navy, the ROK Navy established a task force called Maritime Task Flotilla Seven in February 2010.
Since 2009, a Chungmugong Yi Sunshin-class destroyer from the task force is being deployed as the Escort Task Group (Cheonghae) in response to piracy off the coast of Somalia. On January 21, 2011, naval commandos of the task group carried out an operation, and succeeded in rescuing the crew of the hijacked MV Samho Jewelry. As a humanitarian operation, the unit was dispatched to evacuate South Koreans and foreign nationals from war-torn Libya in 2011 and 2014.
The ROK Navy completed a new naval base called Jeju Civilian-Military Complex Port in February 2016 on the southern coast of Jeju Island to protect the sea lines of communication. In order to support ocean-going operations, the ROK Navy commissioned the 10,000-ton logistics support ship, ROKS Soyang (AOE 51), and launched the first locally designed 3,000-ton submarine, Dosan Ahn Changho (SS 083) in September 2018.
The ROK Navy continued shipbuilding programs to upgrade the fleet with local shipbuilders: In order to replace the aging Pohang-class corvettes and Ulsan-class frigates, and to take over multi-role operations such as coast patrol and anti-submarine warfare, the ROK Navy commissioned six 2,300-ton Incheon-class frigates between 2013 and 2016, and the lead ship (FFG 818) of the 2,800-ton Daegu-class frigates in March 2018. Two ex-USN Edenton-class salvage and rescue ships were replaced with two locally built 3500-ton Tongyeong-class salvage and rescue ships between 2014 and 2016. The Navy commissioned a 3,000-ton minelayer, ROKS Nampo (MLS 570) in June 2017. The lead ship of the PKX-B fast rocket craft, ROKS Chamsuri 211 (PKMR 211), was commissioned in November 2017 to relieve the aging fleet of Chamsuri-class patrol craft. The ROK Navy commissioned four 4,500-ton Cheonwangbong-class dock landing ships between 2014 and 2018. In May 2018, the Navy launched the Marado (LPH 6112), which was the second ship of the Dokdo-class amphibious transport dock. In June 2018, the Navy launched a 4,500-ton training ship, the Hansando (ATH 81), which was also designed as a casualty receiving and treatment ship (CRTS).
In 2019, the Navy updated its strategic vision for the 100th anniversary of the ROK Navy as "Navy Vision 2045". As part of the vision, Admiral Sim Seung-sub, the Chief of Naval Operations proposed to build an ICT-based, system-driven "Smart Navy".
The Republic of Korea Navy includes the Republic of Korea Navy Headquarters, Republic of Korea Fleet, Republic of Korea Marine Corps, Naval Education and Training Command, Naval Logistics Command, and Naval Academy. The Chief of Naval Operations (CNO) is the highest-ranking officer of the ROK Navy.
As of April 2019, the following people were in office:
The ROK Navy is led by the Chief of Naval Operations (CNO). The Republic of Korea Navy Headquarters is located within the Gyeryongdae complex, the tri-service headquarters in Gyeryong, includes the office of the Chief of Naval Operations and various agencies and staff functions.
The CNO is a four-star admiral and a member of the Joint Chiefs of Staff. The CNO oversees the administration of organizing, recruiting, training, equipping, supplying, and mobilizing the ROK Navy. Despite the title, the Chief of Naval Operations does not have operational command authority over combat units (i.e. Republic of Korea Fleet, Republic of Korea Marine Corps). The CNO is an administrative position based in the Gyeryongdae complex, and exercises supervision of Navy organizations as the designee of the Minister of National Defense. Operational command of combat units falls within the purview of the Chairman of the Joint Chiefs of Staff who reports to the Minister of National Defense.
The Republic of Korea Fleet, the highest operational command of the ROK Navy, was established in September 1953. Headquartered at Busan Naval Base, the Commander Republic of Korea Fleet (formerly Commander-in-Chief Republic of Korea Fleet) is responsible for naval operations. COMROKFLT, a three-star admiral, also serves as the Commander Naval Component Command (CNCC) of the ROK-US Combined Forces Command (CFC).
The Republic of Korea Fleet has three numbered fleets each assigned to the seas east, west, and south of South Korea:
For various types of naval operations, the ROK Fleet has a submarine force, two surface flotillas, a naval aviation force, a special warfare force, and units for combat readiness and meteorology/oceanography:
In 1986, the ROK Navy reorganized its patrol forces into three fleets: the First Fleet, Second Fleet, and Third Fleet. The three numbered fleets, each is led by a rear admiral (upper half), are responsible for protecting the coastal water around South Korea: The First Fleet is for the eastern naval sector, the Second Fleet is for the western naval sector and the Third Fleet is for the southern naval sector including Jeju Island. Each fleet includes a Maritime Battle Group, Logistics Squadron, Base Squadron, and Training Squadron. The Maritime Battle Group comprises squadrons of patrol forces composed of Kwanggaeto the Great-class destroyers, Daegu-class and Incheon-class frigates, Ulsan-class frigates, Pohang-class corvettes, and patrol vessels (Yoon Youngha-class fast missile craft, Chamsuri 211-class fast rocket craft, Chamsuri-class fast patrol boats).
Headquartered in Jinhae, the Submarine Force Command was established in February 2015. The ROK Navy's submarine unit had a humble beginning with three Dolgorae-class midget submarines in June 1990. After acquiring ROKS Chang Bogo (SS 061), a Type 209-class submarine, the Submarine Squadron 57 of the Component Flotilla Five was upgraded to the Submarine Flotilla Nine in October 1995. Since then, it has been playing the role of the ROK Navy's core strength.
The Submarine Force Command, which is led by a rear admiral (upper half), includes six Submarine Squadrons with Type 214 submarines (Sohn Wonyil class) and Type 209 submarines (Chang Bogo class). In September 2018, the ROK Navy launched the first locally designed 3,000-ton submarine, Dosan Ahn Changho (SS 083).
The Submarine Force Command offers the International Submarine Education & Training Program (ISETP) for submariners around the world.
Headquartered in Jinhae, the Component Flotilla Five has been the matrix of various units conducting naval component operations such as anti-submarine warfare (ASW), mine warfare, amphibious warfare, salvage and special operations. As a successor to the Flotilla One and Flotilla Two, the Component Flotilla Five was founded in 1986 with the ASW Squadron 51 (later to become Maritime Task Flotilla Seven), Mine Squadron 52, Amphibious Squadron 53, Service Squadron 55 (later Sea Salvage & Rescue Unit), and Special Warfare Squadron 56 (later Naval Special Warfare Flotilla). In 1990 and 2007, the Submarine Squadron 57 (later Submarine Force Command) and Training Squadron 509 (later Naval Battle Training Group Eight) were established respectively. As of December 2018, the Component Flotilla Five was composed of the Mine Squadron 52, Amphibious Squadron 53, and Naval Mobile Construction Squadron 59. The Commander Component Flotilla Five is a rear admiral (lower half).
Headquartered in Pohang, the Commander Air Wing Six is responsible for the operation of naval aircraft. South Korean naval flying started in 1951, with the reconstruction of a former USAF T-6 Texan for naval duties. In 1957, the ROK Navy established the Fleet Aviation Unit, which became the Fleet Air Wing in 1977 when the Navy strengthened its naval aviation force by acquiring Grumman S-2 Tracker ASW aircraft and Aérospatiale Alouette III helicopters. In 1986, the Fleet Air Wing was renamed the Air Wing Six.
The Air Wing Six has naval air stations in Pohang (K-3), Mokpo (K-15), Jinhae (K-10), and a detached unit at Jeju International Airport. The Air Wing Six, which is led by a rear admiral (lower half), includes three air groups, and operates about 70 fixed-wing and rotary-wing aircraft such as P-3CK Orion maritime patrol aircraft and AW159 Wildcat ASW helicopters.
The ROK Navy plans to upgrade the Air Wing Six to a naval air force command.
Since the 1990s, the ROK Navy has been trying to build an ocean-going fleet to protect the sea lines of communication. In 2001, President Kim Dae-jung revealed that the Navy will have a task force called "Strategic Task Fleet" (Jeollyak-gidong-hamdae), which will "protect national interests in the five oceans and contribute to world peace."
As part of the plan, the ROK Navy established a task force called Maritime Task Flotilla Seven on February 1, 2010, which evolved from the ASW Squadron 51 of the Component Flotilla Five. It is led by a rear admiral (lower half), and headquartered at Jeju Naval Base in Jeju Island. The task force is responsible for the defense of South Korea against sea-borne threats and protection of its sea lines of communication. The Maritime Task Flotilla Seven includes three surface squadrons: The Maritime Task Squadron 71 and 72 are composed of three Sejong the Great-class AEGIS guided-missile destroyers and six Chungmugong Yi Sunshin-class destroyers; the Maritime Mobile Logistics Squadron 73 is composed of Soyang-class and Cheonji-class fast combat support ships.
A Chungmugong Yi Sunshin-class destroyer of the Maritime Task Flotilla Seven is being deployed as the Escort Task Group (Cheonghae) in response to piracy in shipping lanes off the coast of Somalia. As a humanitarian operation, ROKS Munmu the Great (DDH 976) of the task group was dispatched to evacuate South Koreans and foreign nationals from war-torn Libya in 2014.
The ROK Navy plans to upgrade the Maritime Task Flotilla Seven to a fleet with 18 destroyers.
The ROK Navy includes the Republic of Korea Marine Corps, which functions as a branch of the Navy. The ROK Marine Corps is responsible for conducting amphibious operations with the ROK Navy. The Marine Corps, with 29,000 personnel, is organized into two divisions and two brigades under the Headquarters ROK Marine Corps. The Commandant of the Republic of Korea Marine Corps is a three-star general. The ROK Marine Corps has about 300 tracked vehicles including assault amphibious vehicles, main battle tanks, and self-propelled artillery.
Headquartered in Jinhae, the Naval Education and Training Command is one of the two major shore commands of the ROK Navy. The Command is responsible for training, education and professional development of the Navy's active duty Sailors. One of its primary roles is to conduct the initial orientation and basic training for new recruits of the Navy and the Korea Coast Guard. The Naval Reserve Officer Training Corps (NROTC) is under the Naval Education and Training Command. The Naval Education and Training Command is led by a Vice Admiral.
The Naval Logistics Command is the other major shore command of the ROK Navy. It is located in Jinhae. The Command delivers logistics and support to the Navy, and is committed to the Navy's combat readiness. It includes the Naval Ship Yard, the Naval Supply Center, the Naval Ordnance Ammunition Center, and the Naval Technology Research Institute. The Naval Logistics Command is led by a rear admiral (upper half).
The Republic of Korea Naval Academy is a four-year coeducational service academy located in Jinhae. It was established in 1946. Graduates are commissioned as Ensigns in the Navy or Second Lieutenants in the Marine Corps. The Naval Academy also hosts the Officer Candidate School (OCS), which provides training to become commissioned officers for civilian college graduates and candidates with military experience. The Superintendent of the ROK Naval Academy is a Vice Admiral.
South Korea has a joint military partnership with the United States as outlined by the Mutual Defense Treaty signed in October 1953. The ROK Navy has worked closely with the U.S. Navy to promote regional stability.
Headquartered at Busan Naval Base, the Commander U.S. Naval Forces Korea (CNFK) is a shore command of the United States Navy that serves as the shore support agency for all U.S. naval activity in South Korea. The U.S. Naval Forces Korea was established in July 1957, with headquarters in Seoul.
Originally established as the U.S. Naval Advisory Group Chinhae Detachment, the Commander Fleet Activities Chinhae (CFAC) is a U.S. Navy installation in Jinhae.
The ROK Navy operates several naval bases in South Korea: Jinhae, Busan, Donghae, Pyeongtaek, Mokpo, Incheon, Pohang, Jeju Island, Baengnyeong Island. Naval air stations are in Pohang, Mokpo, and Jinhae.
Situated in the southeastern coast of the Korean Peninsula, Jinhae has been the major naval port in Korea since the Imperial Japanese Navy built a naval base during the Japanese occupation period. After Korea was liberated from the Empire of Japan, the Korean Coast Guard (later the ROK Navy) was formed in Jinhae. Jinhae is the principal homeport of the Republic of Korea Fleet, and hosts vital naval facilities including the Naval Shipyard. The Jinhae Naval Base Command is responsible for protecting the area.
Located in South Korea's second most-populous city after Seoul, Busan Naval Base has become another major naval base for the ROK Fleet since its headquarters moved from Jinhae in 2007. The base can accommodate up to 30 naval ships as big as the Nimitz-class aircraft carrier.
Donghae, Pyeongtaek, and Mokpo hosts the headquarters of the First, Second and the Third Fleet respectively. Incheon hosts the Incheon Naval Sector Defense Command under a one-star admiral responsible for protecting littoral waters close to Seoul, the nation's capital. Pohang has a naval base for amphibious forces such as the 1st Marine Division ("Sea Dragon") located nearby.
In February 2016, the ROK Navy completed a new naval base on the southern coast of South Korea's largest island - Jeju, which lies in the Korea Strait. Jeju Naval Base was established to protect the sea lines of communication and to strengthen the Navy's control over the seas around South Korea. It is home of the Maritime Task Flotilla Seven and the Submarine Squadron 93. The base is also known as Jeju Civilian-Military Complex Port because it was designed to be jointly used by military and civilians; there is a pier and terminal for cruise ships. The base can host up to 20 naval vessels and two 150,000-ton cruise ships at the same time.
Jeju Naval Base was the venue for the international fleet review 2018 in October 2018.
The ROK Navy has about 70,000 personnel, including the 29,000 members of the ROK Marine Corps.
Military service is mandatory for all South Korean men. In the ROK Navy, all members are volunteers, with enlisted seamen serving for 23-month periods, and enlisted Marines serving for 21-month periods; commissioned officers, warrant officers, and petty officers serving longer terms than those of enlisted seamen, or as career. Women can volunteer as officers, warrant officers, or petty officers. In 2001, six female ensigns, who had become commissioned officers through the Officer Candidate School, were assigned to serve on surface ships of the ROK Navy, for the first time.
There are several paths to becoming a commissioned officer in the ROK Navy, including the Naval Academy, Officer Candidate School (OCS), and Naval Reserve Officer Training Corps (NROTC). Officer Candidate School, located at the Naval Academy, Jinhae, provides training for candidates with current or prior enlisted experience in the military and civilian college graduates, which take majority in OCS.
The warrant officer rank in the South Korean armed forces falls in between that of non-commissioned and commissioned officers. In the ROK Navy, warrant officers are mostly former non-commissioned officers who had earned the rating of Sangsa (Chief petty officer) or Wonsa (Master chief petty officer) and who had been selected for and completed the warrant officer candidate program. Other routes include the naval aviation program and Air Intercept Controller (AIC) program; a small number of warrant officers serve as language officers who specialize in English translation and interpretation.
Warrant officers mess in the wardroom with commissioned officers.
Petty officers originate from a petty officer candidate program, which trains military personnel and civilians who take majority - seamen experience is not required to become petty officers. In the ROK Navy, personnel with ranks of Hasa (Petty officer) through Wonsa are considered petty officers (i.e. non-commissioned officers). Those at Sangsa and Wonsa are further referred to as “CPO” (chief petty officer) collectively and considered a separate community within the Navy. “CPO”s have privileges such as separate dining and living areas.
There are the appointments of Juim-wonsa and Juim-sangsa equivalent to that of the U.S. Navy's command master chief petty officer (CMDCM). The positions are filled by senior Wonsa and Sangsa respectively and unlike their U.S. Navy counterparts, the ROK Navy Juim-wonsa and Juim-sangsa wear the same standard rate insignia of Wonsa or Sangsa with an identification badge. Every ROK Navy establishment and ship has either a Juim-wonsa or Juim-sangsa.
In the ROK Navy, seamen are referred to as "Subyeong" (Korean: 수병; Hanja: 水兵). Normally the enlisted seamen serve in the Navy for 23 months; civilian recruits get initial trainings at the basic military training center in Jinhae as Ideungbyeong (Seaman 2nd class). After completing their military services as Byeongjang (Leading seaman), most of them are transferred from active duty to the naval reserve. Others continue the military service as Hasa (Petty officer) and may become career petty officers.
ROK Navy uniforms, then as now, are based on US Navy uniforms with some notable differences. Petty officers, not just chief petty officers, wear uniforms identical to that of a commissioned officer's uniform except with different insignia, and petty officers wear a combination cap with a white cover and a gold chinstrap. Seamen wear dungaree trousers, chambray shirts and "dixie cup" hats as their work uniforms. Honor guards and musicians of the navy bands of seaman rates wear sailor caps bearing "Republic of Korea Navy" in Korean (Hangul lettering) with the dress uniforms, musicians of petty officer rating onward and officer ranks wear peaked caps.
In the ROK Navy, as in the rest of the ROK Armed Forces, ranks fall into one of four categories: commissioned officer, warrant officer, petty officer (non-commissioned officer), and seaman, in decreasing order of authority. Commissioned officer ranks are subdivided into flag officers, senior officers (lieutenant commander through captain), and junior officers (ensign through lieutenant).
ROK Navy commissioned officer ranks have two distinct sets of rank insignia: On dress uniform a series of stripes similar to Commonwealth naval ranks are worn; on service uniforms, working uniforms, and special uniform situations (combat utilities and flight suits), the rank insignia are the same as the equivalent rank in the Army or the Air Force. The warrant officer rank insignia is denoted by a gold-colored Sowi insignia, and a single broken stripe.

The ROK Navy frequently participates in multinational exercises and international activities. Also it has engaged in several peacekeeping operations since the turn of the 21st century.
Since March 2009, the ROK Navy has deployed the Escort Task Group (Cheonghae) in response to piracy in shipping lanes off the coast of Somalia. The task group is composed of a Chungmugong Yi Sunshin-class destroyer and about 30 naval special warfare personnel. The group operates as part of the multinational task force, Combined Task Force 151 of Combined Maritime Forces (CMF). ROKS Munmu the Great was the first ship to be deployed as part of the unit to Somali waters. On January 21, 2011, South Korean naval commandos of the task group carried out Operation Dawn of Gulf of Aden, an operation to rescue the crew of the hijacked MV Samho Jewelry and succeed in rescuing the crew and killing or capturing all of the pirates on board.
In October 1998, the ROK Navy hosted its first international fleet review in commemoration of the 50th anniversary of the Republic of Korea and its armed forces off coast of Busan and Jinhae. 21 ships from 11 countries (Australia, Bangladesh, France, India, Indonesia, Japan, New Zealand, Philippines, Singapore, United Kingdom, United States) participated in the fleet review as well as 34 ships and 15 aircraft from South Korea. The ROK Navy hosted its second international fleet review off coast of Busan in October 2008 to celebrate the 60th anniversary of the South Korean government. 22 ships from 11 countries (Australia, Canada, China, India, Indonesia, Japan, Russia, Singapore, Thailand, United Kingdom, United States) participated in the fleet review as well as 33 ships and 27 aircraft from South Korea.
The Cruise Training Unit – ROKS Kwaggaeto the Great (DDH 971), ROKS Jeju (FF 958) and ROKS Cheonji (AOE 57) participated in International Fleet Review 2002 commemorating the 50th anniversary of JMSDF in Tokyo Bay. The Cruise Training Fleet – ROKS Chungmugong Yi Sunshin (DDH 975) and ROKS Cheonji (AOE 57) - visited the United Kingdom in order to take part in the International Fleet Review for Trafalgar 200 in 2005. In April 2009, ROKS Dokdo (LPH 6111) and ROKS Kang Gamchan (DDH 979) attended an international fleet review to celebrate the 60th anniversary of the founding of the Chinese People's Liberation Army (PLA) Navy in Qingdao. In August 2009, the Cruise Training Flotilla – ROKS Choi Young (DDH 981) and ROKS Daecheong (AOE 58) participated in the Indonesian International Fleet Review, which commemorates the 64th anniversary of Indonesian independence.
The ROK Navy hosted its third international fleet review off coast of Jeju Island in October 2018. 15 ships from 9 countries (Australia, Brunei, Canada, India, Russia, Singapore, Thailand, United States, Vietnam) participated in the pass-in-review as well as 24 ships and 24 aircraft from South Korea. In April 2019, ROKS Gyeonggi (FFG 812) attended an international fleet review to celebrate the 70th anniversary of the PLA Navy in Qingdao.
There are about 150 commissioned ships with the ROK Navy. The naval aviation force consists of about 70 fixed-wing and rotary-wing aircraft.
The ROK Navy has 16 submarines, 12 destroyers, 13 frigates, 13 corvettes, 64 patrol vessels, 14 amphibious warfare ships, 11 mine warfare ships and 17 auxiliary ships in commission (a total displacement of about 215,000 tonnes).
There are four ship ratings: A first-rate ship (Sohn Wonyil-class SS, DDG, DDH, LPH, MLS, and AOE) is commanded by a captain; a second-rate ship (SS, FFG, FF, PCC, LST, ATS, and ASR) by a commander; a third-rate ship (PKG, MSH, and MHC) by a lieutenant commander; and a fourth-rate ship (PKMR, PKM, and LSF) is commanded by a lieutenant or a warrant officer.
The ROK Navy employs the U.S. Navy-style letter based hull classification symbols to designate the types of its ships and hull numbers to uniquely identify its vessels (e.g. DDH 975[note 4]). The names are that of the historical figures, Navy heroes, provinces, cities, counties, peaks, lakes, islands, and birds. The Chief of Naval Operations selects the names of ships.
The ship prefix for all the commissioned ROK Navy ship is ROKS (Republic of Korea Ship) when the names of ships are written in English.

The KSS program was a three-phased program to build up the ROK Navy's submarine forces. Before the KSS program, the submarine fleet of the ROK Navy consisted of midget submarines, such as the Dolgorae-class submarine and SX 756 Dolphin-class submarine, which had limited capabilities for inshore operations.
Through the first phase, KSS-I, the ROK Navy acquired nine 1,200-ton Chang Bogo-class submarine. For the second phase, KSS-II, the ROK Navy planned to acquire nine 1,800-ton Sohn Wonyil-class submarines with Air-Independent propulsion (AIP) system; the lead boat of her class, ROKS Sohn Wonyil (SS 072) was launched at a shipyard of Hyundai Heavy Industries on June 9, 2006. The Type 214 submarine is expected to play a key role in safeguarding the country's maritime interests. For the third phase of the program, the lead boat of KSS-III, the Dosan Ahn Changho (SS 083) was launched in 2018. A total of nine 3,000-ton KSS-III submarines are expected to be built in South Korea with indigenous technologies (i.e. not going under license as the previous KSS-I and KSS-II submarines).
The KSS-III submarines will be able to fire submarine launched ballistic missiles (SLBMs): Prompted by North Korea's development of the KN-11 SLBM, a vertical launching pad will be installed on the submarines for a missile expected to be developed by 2020. KSS-III submarines will have six vertical missile launch tubes that could house Hyunmoo-2B short-range ballistic missile with a range of 500 km (310 mi).
The KDX program was a three-phased program to modernize the surface fleet by developing and constructing new destroyers for the ROK Navy with advanced combat systems and weaponry. The outcomes of this program include the Kwanggaeto the Great-class destroyers, which are the first ROK destroyers to be armed with surface-to-air missiles; the Chungmugong Yi Sunshin-class destroyers; and the powerful Sejong the Great-class destroyer, which are equipped with the sophisticated AEGIS combat system for air-defense and anti-missile operations. These new destroyers replaced antiquated destroyers that had been transferred from the U.S. Navy decades ago.
As follow up programs, the ROK Navy plans to build three additional AEGIS destroyers (KDX-III Batch-II) by 2028, and six 6,000-ton destroyers (KDDX) by 2030 as successors of the Chungmugong Yi Sunshin-class destroyers.
The FFX program aims to replace the Ulsan-class frigates and Donghae/Pohang-class corvettes with new 2,300-ton frigates. The total number of the ships to be built is 18 to 24. These frigates will be armed with the American-made Phalanx CIWS system and the rolling airframe missile system, and they will each carry an anti-submarine warfare helicopter.
Through the PKX program, the ROK Navy plans to build a fleet of a next generation patrol craft with Cooperative Engagement Capability and enhanced weaponry such as 76 mm guns and the KSSM anti-ship missiles. There are two variations: PKX-A and PKX-B. The PKX-A is a 570-ton patrol craft with anti-ship missiles; PKX-B is a 200-ton patrol craft. 18 PKX-As and 34 PKX-Bs are planned.
On 28 June 2007, the lead ship of PKX-A, ROKS Yoon Youngha (PKG 711), was launched at the shipyard of Hanjin Heavy Industries in Busan. All 18 PKGs were commissioned by 2018 to replace the aging Chamsuri-class patrol craft. The lead ship of PKX-B, ROKS Chamsuri 211 (PKMR 211), was commissioned in 2017.
The LPX program was the ROK Navy's new amphibious warfare ship program for which Hanjin Heavy Industries has provided the general design package. The ROK Navy's requirements for the new amphibious warfare 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, the lead ship (LPH 6111) of the 14,500-ton Dokdo-class amphibious transport dock was launched at the shipyard of Hanjin Heavy Industries in Busan. The first air-cushion landing craft of LSF-II (ROKS Solgae 631) was delivered for ROKS Dokdo in April 2007. In October 2009, the ROK Navy revealed a plan to commission another LPX around 2018. The Marado (LPH 6112) was launched in May 2018.
The ROKN plans to build and commission an uncertain number of mine countermeasure ships similar to the Yangyang class. MSH phase II has been delayed.
The ROK Navy plans to commission a new 4,500-ton training ship (ATX) for midshipmen and officer candidates. The Hansando (ATH 81) was launched on November 16, 2018. She was designed as a training ship, and casualty receiving and treatment ship (CRTS). The Hansando is expected to be commissioned in 2021
The ROKN plans to commission an uncertain number of 12,000-ton fast combat support ships (AOE) to relieve the 9,000-ton Cheonji-class ships. The lead ship, ROKS Soyang (AOE 51), was commissioned in 2018.
The ROK Navy plans to commission a new submarine rescue ship around 2022. Daewoo S&ME (DSME) will build the ship, and UK-based underwater systems developer JFD will deliver a deep-submergence rescue vehicle (DSRV) for the ROK Navy in 2021.
The ROK Navy had acquired eight P-3C aircraft by 1996 through the Maritime Patrol Aircraft-I phase I. Through the phase II, eight more P-3CK maritime patrol aircraft (ex-USN P-3B) had been delivered to the ROK Navy by 2010 after undergoing extensive refurbishment and modernization.
In May 2013, it was announced that the Defense Acquisition Program Administration (DAPA) was commencing a 1 trillion won ($900 million) procurement program to acquire up to 20 new anti-submarine warfare aircraft to replace the existing fleet of 16 P-3Cs. While possible candidates include the C-295 MPA, P-8 Poseidon and the SC-130J Sea Hercules, DAPA was considering a plan to procure 12 to 20 ex-USN S-3 Vikings for the ROKN. In 2017, the ROK Navy canceled plans to purchase refurbished and upgraded S-3 Viking aircraft. In 2018, the South Korean government announced a plan to acquire six P-8 Poseidon.
Through Maritime Helicopter-I, the ROK Navy took delivery of the first batch of 12 Mk.99 Lynx helicopters in 1991; a second batch of 13 Mk.99A Super Lynx helicopters began delivery in 1999. The first Lynx batch was later upgraded to the same standard as the second batch; the changes included the adoption of a new radar, FLIR, and ESM systems.
On 15 January 2013, the Defense Acquisition Program Administration announced the selection of the AW159 Wildcat to fulfill a requirement of the ROK Navy for a maritime helicopter, winning out against the MH-60R Seahawk. The batch of eight aircraft were chosen to perform search-and-rescue missions, anti-submarine warfare and surveillance. On 13 June 2016, the Navy took delivery of four Wildcats. The helicopters operate from the Navy's Incheon-class guided missile/coastal defense frigates. The remaining four were delivered in late November 2016.
In January 2019, the South Korean government was considering ordering 12 more maritime helicopters to further strengthen the Navy's anti-submarine capabilities; options include the AW159 and MH-60 Seahawk.
The ROK Navy had planned to acquire new mine countermeasure helicopters by 2012 with a budget of 480 billion won. AgustaWestland EH-101, NHIndustries NH-90, and Sikorsky MH-60S were considered as possible candidates for the acquisition program before it decided to hold the program due to global financial crisis that hit the world in 2008.
Romanization is according to Revised Romanization of Korean (adopted in 2000), with exceptions of personal names. Names of ships commissioned before 2000 might have been romanized according to McCune–Reischauer. Examples of changes (M-R → RR): Chinhae → Jinhae; Inchon → Incheon; Kangnung → Gangneung; Kimpo → Gimpo; Pusan → Busan; Taegu → Daegu.
Chamsuri-class patrol vessels (Hangul: 참수리급 고속정) are naval boats that function as patrol boats. These entered service with the Republic of Korea Navy in the 1970s, and have since seen service with three other navies, of which the Philippine Navy is currently the largest import user.
These boats were built by the Hanjin Industrial SB, Chinhae, and Korea SB & Eng. Masan shipyards.These boats, also referred to as patrol killer medium "PKM", were built in two batches: the 201 series, and the more heavily armed 301 series. Early PKM 201 series boats were initially armed with one 40 mm/60 Bofors Mk.3, one twin 30 mm/75 Emerlec EX-30, and two 20 mm/70 Mk.10 AA. Late PKM 201 boats were armed with one twin 30 mm/75 Emerlec EX-30, one or two turreted single 20 mm Vulcan Gatlings, and two single 12.7 mm machine guns. The PKM 301 boats were armed with one 40 mm/60 Bofors in a fully enclosed mount, two turreted single 20 mm Vulcan Gatlings, and two single 12.7 mm machine guns (before the Second Battle of Yeonpyeong two single 7.62 mm M60 machine guns). The Chamsuri-class boats are being retired and replaced by Gumdoksuri-class patrol vessel in the Republic of Korea Navy.Chief of Naval Operations (South Korea)
