There are too many variables to count to in this case. To be honest I still doubt about the continuation of F15ID when are still pursuing IFX & Rafale. Tho the previous blue print is for Kupang (new fighters) & Sorong (any avaiable fighters) it can still be changed considering the 14th SQA now fill with F16. The 14th was meant to be filled with Heavy Fighters with a large coverage area, so I am not sure if those F16 are on a temp status or not.
I personally wanted to see if those A300 mrtt is going to be executed, if it becomes reality then the need for heavy fighters is lessen with the coming of air tankers.
As for Suokhoi lets see what kind of fighters we have in 2030, taking into account the geopolitics condition on that year we will then see what comes next. Until then the Rafale will keep on pouring until 2030 unless the new govt replace the plan...
