The Type 212A is a class of diesel-electric submarine developed by Howaldtswerke-Deutsche Werft AG (HDW) for the German Navy, and the Italian Navy where it is known as the Todaro class. It features diesel propulsion and an additional air-independent propulsion (AIP) system using Siemens proton-exchange membrane (PEM) compressed hydrogen fuel cells. The submarines can operate at high speed on diesel power or switch to the AIP system for silent slow cruising, staying submerged for up to three weeks with little exhaust heat. The system is also said to be vibration-free and virtually undetectable.
An attack submarine or hunter-killer submarine is a submarine specifically designed for the purpose of attacking and sinking other submarines, surface combatants and merchant vessels. In the Soviet and Russian navies they were and are called "multi-purpose submarines". They are also used to protect friendly surface combatants and missile submarines. Some attack subs are also armed with cruise missiles, increasing the scope of their potential missions to include land targets.
Submarine warfare is one of the four divisions of underwater warfare, the others being anti-submarine warfare, mine warfare and mine countermeasures.
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.
Jang Bo-go (787–841), whose childhood name was Gungbok or Gungpa (Korean: 궁파), was a Sillan who rose to prominence in the Later Silla period of Korea as a powerful maritime figure who effectively controlled the Yellow Sea, and dominated the trade between Silla, Heian Japan, and Tang China for decades. His impressive fleet of ships was centered in Wando, an island in South Jeolla Province. So influential a figure did Jang become in late Silla politics that he was granted official office as maritime commissioner of the Cheonghaejin Garrison and came near to marrying his daughter into the Silla Royal House before his assassination in 841. He was worshipped as a god in China, Korea, Japan, and Vietnam following his death.
The Korean Attack Submarine program, KSS meaning Submarine, is a three-phased project to build up the Republic of Korea 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.
The Type 209 is a range of diesel-electric attack submarines developed exclusively for export by Howaldtswerke-Deutsche Werft of Germany. Five class variants, including modifications thereof, have been successfully exported to 15 countries, with 68 submarines being built and commissioned to five different variants between 1971 and 2021. More boats have been built to modified designs.
ROKS Jang Bogo (SS-061) is the lead ship of the Jang Bogo-class submarine of the Republic of Korea Navy, and was the first submarine to serve with the navy. It is one of the Type 209 submarines built for export by Germany.
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 Nagapasa class is an upgraded variant of the Jang Bogo class, also known as Improved Chang Bogo. The vessels were built by the South Korean Daewoo Shipbuilding & Marine Engineering (DSME) and the Indonesian PT PAL. As of 2021, six ships have been planned, which were divided into two batches. Batch 1 consists of three ships and all are already commissioned. Batch 2 also consists of three ships that are in the early development stage. The class is named for weapon of Indrajit, Nagapash.
ROKS Yi Cheon (SS-062) is the second ship of the Jang Bogo-class submarine of the Republic of Korea Navy, and was the second submarine to serve with the navy. She is one of Jang Bogo-class submarines to be built in South Korea.
ROKS Choe Museon (SS-063) is the third ship of the Jang Bogo-class submarine of the Republic of Korea Navy, and was the second submarine to serve with the navy. She is one of Jang Bogo-class submarines to be built in South Korea.

The Cakra class is a class of two Type 209/1300 attack submarines developed by Howaldtswerke-Deutsche Werft of Germany that were bought and commissioned by the Indonesian Navy in the 1980s. The second member of the class, KRI Nanggala sank in 2021 with all hands during an exercise. The lead submarine, KRI Cakra, remains in service.
