In post #3,192 I already post cost share KFX/KF-21 for this year allocation. Thus Indonesia so far shown 'commitment' to at least pay up their 7% (down from 20%) share dues in overall RnD project. However whether they want to continue on the plan 48 KF/IF-21, that's the question.
Question of USD 8-12bio allocation budget. That budget 'if' can be afforded the choice are:
1. 24-36 F-15EX,
2. Another 42-48 Rafale,
3. 48 KF-21.
4. 36 Flankers
Because simply there's question of affordability of Indonesia fiscal allocations for those projects. Seems has to be chooses which will be taken. I got feeling #1 will be taken, as part of negotiations with US on Tariffs. Indonesian ministerial level team already go to US to negotiate, and potentially F-15EX can be part of negotiations.
However Dasault already talk (base on Rumours) with DI on setting up assembly and some Production line for Rafale. That's potentially will use production hangar that's being prepared for KF-21/IF-21. Thus KF/IF-21 procurement fortune, seems going to be decide as whether Indonesia/DI still goes with KAI or Dasault as fighter program partner.
2 Sq of Hawk 200/100 already been talk by TNI-AU going to be replace by Rafale when they are operational. That 1sq of ex Qatar Mirage 2000-5 can also be replace later on when all 3 Sq of Rafale being operational. The target still 11sq Fighters being operational. Currently TNI-AU have 3 F-16, 2 Hawk 200/100, 1 Flankers, 1 TA-50 and 1 Super Tucano.
So if they got later on 3 Sq Rafale, 3 F-16, 1 TA-50 and 1 Sq Super Tucano, then the question for whose going to fill additional 3 Sq to make it 11 can be:
1. F-15EX (up to 36),
2. Rafale (up to 42-48),
3. KF-21 (up to 48),
4. Flankers (up to 36).
At least that's the way I see it on the plan so far base on Rumours and media bits. Flankers seems the choice on most affordability, if they can't get the higher budget number for others. Although China can also be another candidate on affordability factor with J-10C.
Like I said before I got sense they can be force to go for #1 due to Tariff negotiations, personally I hope for #2 but if looking on budget affordability #4 can come out, but 'only' if they can nego with Trump on CAATSA. However if negotiations failed, they can go to surprise #5 of J-10C just simply to give middle finger to Trump

. Something I sense least likely to happen, but with Trump card, who knows.
