sorry... i dont know whats your point..
In time being indonesia has choose DSME CBG submarine for indonesian navy, right?
That some people said its not good.
But i say in opposite, it is good! even not the best. Build quality from korea is not that bad people thinked, they got technology support from western country.
Beside, for our submarine we choose the onboard module by ourself...like periscope module from german company, cms from kongsberg. etc
We choose module from good naval defense contractor.. and the most important in that time situation is: the CBG subs price is the best match to our pocket.
We hope from that project we can produced by ourself...after that we can reach the quantity...
So i can simply say: we can defense our water with 20-30 CBG class subs.
