I stand by my opinion that the MinDef is simply adamant on Rafale just to improve his own political chances at presidency. I'm not going to be surprised if at the end he does a complete 180' and announces an order for the F-16V. Because unless some economic miracle happens, the budget and financing limit set by the Ministry of Finance doesn't really allow them to pick anything other than the F-16V.Unless they are dropping plan for Rafale and F-15.
I would say that this news strongly implies that the TNI AU is prioritizing supporting assets over the MRCA program. For the most part I think they know that they need to seriously improve airlift capability (considering Indonesia's geography) as well as improving their early warning system and IADS network. Considering PT LEN is already in cooperation with Leonardo (unlike just an LoI with the Rafale) I wouldn't be surprised if the next big news we hear is either the TNI AU inspecting or procuring the Wedgetail/Erieye or MRTT/KC-46 over the Rafale/F-15.
