I understand this, of course. But by the time the common project materializes, I'm afraid it will already obsolete. Unless, there are some major breakthrough and not only following the established patterns. Like what I'm writing previously: even if it's still subsonic, but if it also applies some stealth technologies in its design then at least it still has a better fighting chance against modern naval combatants.
I would to see Indonesian Naval industry to pick up whatever technologies they yet to be mastered, and that's mean a lot of items on the list
We don't have any mastery on Naval radar development, Naval type Air search radar, ECM, EWS, SATCOM, chaff launcher, jamming decoy, limbo mortar, AShM, surface to air Missiles system, VLS, Naval Marine engine, Naval type artillery gun and so on in which i would need more than hundreds pages to type and list them all from Rakornas between industry, BPPT and Kemhan. At this stage i would be picky anymore
