I have a better proposal for the TNI-AU
1. Sign strategic partnership with Turkey
2. Double the amount of F-16. Get older blocks, upgrade them with Turkish components of the Ozgur project +AESA+Bozdogan/Gokdogan/Gokhan+ a whole assortiment of guided weapons with (partial) license production.
3. Sign agreement to be the first to invest in TF-X with (partial) licence production.
4. Get Aksungur/Akinci/MIUS/TB2/3 also under license plus regional maintenance and service.
5. Get Turkish helicopters T625/T925 and attack helicopters with (partial) license production.
6. A whole lot of air-to-surface missiles from ATMACA and SOM to UMTAS and CIRIT.
7. Radars and SAM also under license production.
8. Other systems not related to the air force
Pro's: Truly kickstarting Indonesian defence industry, no limit to weapons production and procurement (consider yourselves lucky if you have on average 2 AIM-120's for every US fighter that you have)
Cons: forking multiple billions of dollars (10B?) over the course of 10+ years. Cancellation of Rafale+F-15EX and in the long run the KF-X.
Indonesia can do it and the Turks would be willing to. The only thing Indonesia is lacking is the will and ambition. I hope that IDEF-21 will convince the Indonesian MoD to go full Turk
