Not about the pricing...but strings that leads back to US.
it risks embargo n sanctions should indonesia gets into any friction with US allies (aus, nz) or act in any way against US interests be it direct or by proxy.
And there is nothing S.Korea can do about it.
Well if you buys Chinese fighter, you cannot anger Chinese as well, same when you want to buy fighters from Russia. Indonesia bought huge Russian armament during Soekarno regime and Soeharto regime cannot sustain to maintain them because of Indonesia anti-communist stand at that time.
Indonesia doesnt have any territorial dispute with both Australian and New Zealand and we are unlikely to have military conflict with each other after the raise of big dragon unites us all ........
Indonesia/South Korea and USA has alligned interest in Asia Pacific region.
Fighter technology development
Any way this project is the first step for Indonesia to develop jet fighter technology, not only beneficial during the development process but also possibly beyond that. The program will make Indonesia government has strong reasons to set up road map on jet fighter technology development that not only is limited to Indonesian Aerospace which core competencies are in design, fuselage manufacture, integration, and testing but also electronics company like PT LEN Industry and avionics company like PT Info Global.
Any way Indonesian Aerospace also has subsidiary company in turbine sector (PT Nusantara Turbin) that could be engaged for turbo jet technology. As we are speaking now, Indonesia is also undergoing indigenous cruise missile program where turbo jet is also being developed. I am not talking about immediate future, but medium and long term plan at least in span of 15-20 years to come.
Future market in SEA region
While you look like criticizing the program, actually there is big possibility that Malaysia gov has considered to buy this plane, more over after they know the price range which is quite competitive and less expensive than 4 generation fighter like Eurofighter and Rafale (half the price).
I would say Malaysia, Thailand, and Philippinea are potential buyer with at least I predict will buy 100 planes combined for 2030-2036 period alone (in assumption the program is success), not to mention block 2, block 3 and possibly upgrade program from block 1 into block 2 and block 2 into block 3.
