The nature of TNI-AU ( Indonesian AF ) procurement has been talked quite some time in Indonesian AF thread.
@ Gadjah Mada, I'm not entirely agree Indonesian can't get better deal on weapons procurement with US, or other Western suppliers. The thing is (as you have mentioned), corrupt practices is still a big problem/risks within Indonesian procurement. Personally I do believe the current procurement practices is much better than previous administrations, however if saying it's allready up to best practices of accountability and openes/disclosure then no it's much need to improved.
From info that I got from finance ministry, there're still some questions especially when dealing with support packages and other details. The practices to differentiate the procurement budget between main assets and support (i,e airframes and support packages including weapons), being questioned wheter its efficient or not. This resulted the procurement being divided between packages rather one overall package which usually can provide better deal.
I do believe rather than talking Indonesia can't get discount, more talked about the procurement practices. This is not just Indonesian problem, seeing on different forum and media, similar situations can be found on India (for example) where the packages is much bigger but still within India it self raised questions on efficiency , accountability, etc.
@ADMk2, on Indonesian AF it's been discussed that the current 24 ex USAF F-16 block 25 deal plus the upgrade of 10 existing block 15 OCU is a trade off between getting 34 fully upgrade older F-16 or 8-12 new block 52.
This is actually the choice that being offered by US to Indonesian administrations. Getting new F-16 or older but fully upgrade F-16 but with more than twice in term of quantity. Indonesia AF than choose quantity over newer airframes (quality).
Is it make sense. Well it is debatable. However their perspective is those F-16 used as stop gap until KFX or something else can be procured by 2020+. For that they seems believe more on quantity over quality.
In other word, they seems think more on getting more sq wirh older airframes rarher than fewer sq but newer airframes.
