The Pohang class corvettes still available for export do not have the HSA-systems on board, like the first batches.

It's been put by Indonesian Media that ROKN offer 3 second hand corvettes to Indonesia. Some Indonesian defense enthusiats thinking this must be related to ROK effort to revive batch 2 DSME 1400.
It could be right, but I also gather some informal information that ROK also try to compete with Japanese on 30FFM. So far present administration MinDef already commited with Babcock Arrow140 and FREMM. However there's rumour they are looking also for something lighter design for more quantity that can be build by local shipyards (outside PAL).
Japan still try lobby for somekind derivative from their 30FFM. Thus it's probable ROK try to offer their latest iteration on FFG III.

ROK already offering the inventory of Pohang corvettes to Philipine and Vietnam. Perhaps it's part of their diplomacy to enhance SEA nation patroling capabilities in SCS. However I do suspect they offering Pohang as stop gap before move to FFG III design that being build as Pohang replacement anyway.
So almost all sensors and CMS-components on board are not installed in TNI-AL's existing fleet and because of that they are not yet used to operate and maintain them. The Pohangs do also have the LM2500 gasturbines installed, which make them more expensive to operate and maintain compared to the other vessels in our fleet, with exception of the Mandau class fast missile boats.
