The Bunker Group
Yes, that's why this talk on Midget Submarine or UUV is something that I see being push by some faction with 'business' interest backing up. Not entirely what TNI planner have in priority. Things like this as you have put, at most end up as one kind prototype or niche classes.The required budget will be huge, and our government isn't even willing to spend enough for less sophisticated programs like N219, N245 and Elang Hitam UAV. And the Klewang Class trimaran program is ended with a single almost unarmed vessel.
However this litoral (tactical) and ocean going (attack) Submarine consideration seems the one that getting momentum. Off course with election years looking, it will be back to politics of whose going to win. Mind you one of candidate from 'bull' party now has recuit 'shadow' defense 'pundits' that more or less want to pursue Russian or Non Western origin assets or partners for domestic industry. Not surprisingly as those are the factions that back by lobbyists/salesman from opposite side of Twitter guy master.
