DMSE to build South Korea KSS III Batch II class submarine

The Dosan Ahn Changho-class submarines are the final phase of the Korean Attack Submarine program, a three-phased program to build 27 attack submarines for the Republic of Korea Navy

According to information published by Yonhap News Agency on September 10, 2021, the Defense Acquisition Program Administration (DAPA) has signed a 985.7 billion won (US$853 million) deal with Daewoo Shipbuilding & Marine Engineering Co. to build the new KSS III Batch II class submarine.

The KSS III submarines are the final phase of the Korean Attack Submarine program, a three-phased program to build 27 attack submarines for the Republic of Korea Navy between 1994 and 2029. The lead vessel, Dosan Anh Changho, was launched in 2018. It began sea trials in 2019 and is planned to be ready for service by 2020.

The 83.5-meter-long and 9.6-meter-wide submarines can carry 50 crewmembers and can operate underwater for 20 days without surfacing.

The KSS III has a submarine version of the Korean Vertical Launching System which will be able to carry up to ten indigenous “Chonryong” land-attack cruise missiles and “Hyunmoo” submarine-launched ballistic missiles (SLBM), becoming the first submarine in the South Korean navy to have this kind of capability. It also has many other improvements compared to its predecessors built with a greater degree of South Korean technology, especially in the later batches, which will include Samsung SDI lithium-ion batteries.

The KSS III Batch II will be 89 meters long and heavier. This is around five and a half meters longer than the Dosan Ahn Changho, the first submarine built with local technology.
