Under the Jangbogo III programme, the first submarine is due to be launched in 2018 and handed over to the Republic of Korea Navy at the end of 2020 following two years of sea trials. The second submarine will be delivered at the end of 2022. KSS-III is expected to be produced in three batches:
Batch-I consists in the first two hulls to be built by DSME. Remaining tender for the third hull will be released in late 2016.
Batch-II will consist in three hulls with some design changes. They will be fitted with a greater deal of South Korean technology. The winner of basic design and construction of the first hull will be decided in the very near future.
Batch-III will consists in the three remaining hulls (for a total of nine KSS-III submarines across all batches). The last submarine is expected to be delivered in 2029.

The original design of the submarine includes 6x VLS (vertical launch system) tubes. They would accomodate a future cruise missile in development by LIG Nex1 while the launchers would be provided by Doosan. It was announced earlier in the program that Spanish company INDRA was selected to provide its electronic defense system (ESM) PEGASO and Babcock of the UK would design and manufacture the Weapon Handling System for the Batch-I submarine.

It was officialy announced during Euronaval 2014 that Sagem would supply the optronic masts for the class. Flank array sonars will be provided by Korean company LIG Nex1. Hanwha Thales contacted Navy Recognition by email to explain they would supply KSS-III's combat management system. The submarine will be fitted with south korean lithium-ion battery technology.
