Sigma 10514 and Iver Huitfeldt combination initially aim for GP Frigate/Light Frigate replacement on Van Speijk as patrol frigate. Iver base for larger Frigate that have more capabilities on AAW and area defense. Base on what the Danes configuration.
Now, with the changes, as sandhi put it is politically driven more then defense driven. Ego that my 'project/initiative' is matter on Indonesian politicians psyche. So with Damen Light Frigate drop, Iver process stretch and now work as Arrowhead 140 derivative call Red-White Frigate. However now instead develop more on Iver config, seems now it is config that's not really clear. Not clear which supplier on electronics and armament. This it will be build as FFBNW but not quite sure when full config going to be fulfill.
FFBNW also going to be pattern for OPV/Corvette 90. The design as I have put before is 'suspiciously' similar with Damen 9814 Corvette that being offer before to Vietnam:

This project now also clouded in secrecy, as some in media talk about problem with construction stage due to shipyard project financial management. Although some enthusiasts X shown the construction still progressing.
Still this is also shown problem between domestication policy ambition, and reality of local shipyard capabilities. This OPV project is part of MinDef diversification productions. Instead focusing with PAL only. Time will tell if other shipyard capabilities can catch up.
This matter because it will see if domestic can provide the political ambitions for 'made in Indonesia' drive, or reality on defense need must let some or more construction and procurement need to be source from overseas yard.
That's what PPA situation coming. As the productivity on local shipyard not meet the speed needed as TNI-AL fleet face obsolescence issues. This create domestic modifications on some existing assets:

41 vessels need to be done modifications. This from Corvette, Frigate, Patrol Ships and Submarine. This is also ambitious program considering the time line target. However this is less ambitious ones then domestic buildings.
So in paper TNI-AL and MinDef planners actually quite understand and drive on commonality. However as usual in Indonesia, and I believe also in other 'democracies', politics will mess up the technical planners. So I do see commonality will still be aim, but from time to time will be 'distrub' by some political procurement that being taken for one or more 'chaotics' reasoning.
