Nah, I think the author mistyped - it was the F-16 C/D block 52
that they have got in 1994. Lots of typo in that page, eg.
KC-135 was put down as KC-125
btw, I am intriged by this though:
"Technical data and defense services in support of manufacture of
F404, F414, and T700 aircraft engine components and
equipment."
Why did Singapore ask for F404 and F414 engine components? F404
engines are used by A4 that I can understand, but what about F414
which is only used by F-18 E/F - another typo or is there something
we really didn't know... (ie, not public domain yet)
