There has been some talk of these 2 aircraft, along with
supposedly 9 ex-Thunderbird F-16As supposedly leased for training.
Theres just one problem: serial numbers. No one seems to have got
the serial numbers of any of these 11 aircrafts. Dig hard enough
you can get the serials of all the aircraft RSAF has had so far:
the 68 A/B/C/D bought, the 12 leased Block 42 F-16C/D since
returned to the USAF, even the GF-16A in Singapore for ground
instruction by ALS. Yet I've never seen any serial numbers of any
more F-16As bought or leased by the RSAF other than the '87 batch
of 4A and 4B.
So I'm tempted to believe these aircraft never existed, most likely
the order was cancelled/upgraded to the C/D Block 52
I'll stick with 68 for the moment, thank you
