The Korean Attack Submarine program, KSS meaning Submarine, is a three-phased project to build up the Republic of Korea Navy (ROK Navy)'s attack submarine arsenal. 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. The KSS program sought to acquire submarines that can deter hostile submarines and surface ships; protect friendly naval bases and sea shores communications; carry out reconnaissance missions.
Through the first phase, KSS-I, the ROK Navy acquired nine 1,200-ton Jang Bogo-class submarines (장보고 급). [1] For the second phase, KSS-II, the ROK Navy plans to acquire nine 1,800-ton Type 214 submarines equipped with Air-independent propulsion (AIP) [2] the lead ship of her class, ROKS Sohn Won-il (SS 072) was launched at a shipyard of Hyundai Heavy Industries on 9 June 2006. [3] The first batch of these submarines is one of three, the second batch will be one of 6 and a $16 million deal has been awarded to SAAB for the electronics that are going to be used for the vessels delivered in the second batch submarines. [2] The third part of the program, KSS-III began in 2007. This class will have significant improvements when compared to its predecessors. 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). [2]
In May 2009, South Korea decided to delay by two years its KSS-III project, also known as Jangbogo III programme. [2] [4] The project is expected to cost around US$900 million per submarine. [5]
The first KSS-III ship will be ready for service by 2025. The previous plan was to have an operational unit ready by 2017. Due to the relatively heavy displacement of the ship (3000~3500 tons) and the fact that it will be built with local Korean technologies (sensitive technologies might be blocked from export) the production of the submarine was delayed. This new class of ship will have the Korean Vertical Launching System which will be able to carry up to 10 indigenous Chonryong submarine-launched cruise missiles. The first submarine in the Republic of Korea Navy to have this kind of capability. It will also have many other improvements compared to its predecessors. Reports indicate South Korea might even deploy SLBMs inside the vertical launchers. Development of SLBMs by Agency for Defense Development is expected to be completed by 2020. [6] [7] SLBMs will be a derivative of Hyunmoo-2 ballistic missiles. [8]
The first KSS-III heavy diesel-electric submarine construction was launched on 17 September 2018. The name of the first ship of KSS-III has been named Dosan An Chang-Ho, thus KSS-III is now named as Dosan An Chang-Ho-class Submarine. [9] [10] It is expected to undergo 2 years of sea trials and be handed over to the navy in 2020 or early 2021. [5]
It is expected that three batches, with three submarines in each batch, will be built by 2029. [5]

The Type 214 is a class of diesel-electric submarines developed exclusively for export by Howaldtswerke-Deutsche Werft GmbH (HDW). It features diesel propulsion with an air-independent propulsion (AIP) system using Siemens polymer electrolyte membrane (PEM) hydrogen fuel cells. The class combines the design principles of the Type 209 submarine family and the features of the Type 212A submarine. However, as an export design, it lacks some of the classified technologies of the Type 212 such as the non-magnetic steel hull that makes it difficult to detect using a magnetic anomaly detector.
The Republic of Korea Navy, 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 140 commissioned ships in the ROK Navy. 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 Sejong the Great-class destroyers, also known as KDX-III, are three guided-missile destroyers of the Republic of Korea Navy (ROKN).
Hyunmoo is a series of strategic missiles developed by South Korea. Its name refers to the symbol "Black Tortoise" from Chinese mythology, which stands for "Guardian of the Northern Sky".
The Hyunmoo-3 is a cruise missile fielded by the South Korean military designed by Agency for Defense Development (ADD). The name Hyunmoo comes from a mythical beast described as the "Guardian of the Northern Sky", perhaps hinting North Korea.
The Jang Bogo-class submarine or KSS-I is a variant of the Type 209 diesel-electric attack submarine initially developed by Howaldtswerke-Deutsche Werft (HDW) of Germany, intended for service with the South Korean Navy and Indonesian Navy. A Daewoo (DSME)-upgraded model of the Jang Bogo class Type 209 was exported by Korea to Indonesia in 2012, amid heavy competition from Russian, French, and German-Turkish consortiums including from Germany's original Type 209. The variant was considered for possible purchase by Thailand as well, as both newly built and second-hand options. The class is named for ancient Korean maritime figure Jang Bogo.
The Korean Vertical Launching System is a vertical launching system developed by South Korea to be deployed by the Republic of Korea Navy. It is used in the Sejong the Great-class destroyer, KSS-III submarine, and is scheduled to be added to the Daegu-class frigate. The K-VLS can deploy the Cheolmae-2 air defense missile (KM-SAM), Haegung air defense missile (K-SAAM), Hong Sang Eo anti-submarine missile, Haeseong-II, Hyunmoo-3 land-attack cruise missiles and even SLBMs.
The Daegu-class frigate is a class of guided missile frigates of the Republic of Korea Navy (ROKN). The Daegu class is based on the preceding Incheon class, and has otherwise been referred to as the Incheon class batch II, or FFG-II. Eight Daegu-class ships have been commissioned, with the final goal of 20–22 frigates, of all types, in the ROKN. The Daegu-class frigates were built by Daewoo Shipbuilding & Marine Engineering (DSME) and Hyundai Heavy Industries.
The KSS-III or Dosan Ahn Changho-class is a series of diesel-electric attack submarines currently being built for the Republic of Korea Navy (ROKN), jointly by Hanwha Ocean and HD Hyundai Heavy Industries (HHI). The KSS-III is the final phase of the Korean Attack Submarine program, a three-phased program to build 27 attack submarines for the ROKN, between 1994–2029.
