ROK Navy’s 1st 3000 tons KSS-III Submarine ‘Dosan Ahn Chang-ho’ Passes Max Depth Test - Naval News
The first indigenous design and also the largest Submarine ROK build (KSS III) already achieve another milestone of Maximum Depth test.
The ROK in the last IndoDefence also put the model of KSS III in the display. They are not offering this submarine yet to any export customers, however with that gesture in last IndoDefence, I do believe this will be offered to export when the times and demand come.
This is not in Soryu categories yet, but compared on the rough data available on line seems will be comparable enough with the latest Chinese SSK.
