Doubtful, unless they are financed in large part. The AESA is not standard on the C/D Block so these would be upgraded, but maybe not up to V Standard? The lead time would be at least few years unless they are put at the front of the queue.
They did, FA-50 Block 10. I thought they were looking for additional FA-50 in Block 20 with AESA and AIM 9X capability. Also the SKs are looking to integrate an air launched cruise missile which would increase the value of the aircraft significantly. Depending on the terms and price, they would be better off with SK aircraft for a number of reasons. However, an F-16 order may be part of the price for U.S. "protection".
It will be interesting to see if there was a definitive determination of the cause of the crash last month of the Philippine FA-50.
