ROKS Ahn Mu

ROKS Ahn Mu (SS-085) is the second ship of Dosan Ahn Changho-class submarines of the Republic of Korea Navy (ROKN).

Development and design
The Dosan Ahn Changho class incorporates 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 submarines in the ROKN to have this kind of capability. They will also have many other improvements compared to their 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 3800 t 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 (4,250 t submerged), according to the Defense Acquisition Program Administration.

Construction and career
Ahn Mu was laid down on 17 April 2018 at DSME, Geoje and launched on 10 November 2020. She was commissioned on 20 April 2023.
