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 between 1994 and 2029. The lead vessel, Dosan Anh Changho, was launched in 2018. It began sea trials in 2019 and planned to be ready for service by 2020.

Design and description:
The new class will have 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 will also have 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. Measured to displace over 3,800 tonnes (3,700 long tons) submerged during sea trials, they are the largest conventional submarines ever built by South Korea. The Batch II vessels will increase their displacement by approximately 450 t (440 long tons) (4,250 t, 4,180 long tons submerged), according to the Defense Acquisition Program Administration.

KSS-III Batch II:
On 25 April 2016 there was a South Korean Congressional Hearing session held immediately after North Korea's SLBM launch, which raised some important questions about the ROK Navy's submarine capabilities to counter this threat. In response to questions whether the ROK Navy was currently developing capabilities to counter the SLBM threat, the ministry confirmed that the KSS-III Batch-II will undergo redesign process before construction (lasting until 30 December 2018) to accommodate capability upgrades. These upgrades will give the Batch-II submarines better capabilities at both attacking strategic land-based facilities and performing anti-submarine warfare. The Next Generation Submarine Project Team held a "System Functional Review" meeting on the KSS-III Batch-II submarine in late June 2017 which led to a review of the Batch-II design.

Expected changes of Batch-II compared to Batch-I:
Lengthened hull (approximately 6 m (19 ft 8 in))
Increase of VLS cells from 6 to 10
Indigenous combat system and sensors
LiB and, potentially, High-Temperature Superconductor (HTS) motor for integrated full electric propulsion system
