Getting an NGF is important for us, in order to stay ahead in
regional air power, which is catching up at a rapid rate. Hence we
need something to leapfrong the competition and put us all the way
out infront, for an effective detterence, rather then keep aquiring
existing systems in ever increasing numbers.
The F-16 is still effective, but it's in itself approaching the
limit of it's airframe lifecycle. To use it as a replacement for
our Skyhawks would be akin to replacing a 60 year old retiree with
a 45 year old worker. While it may be cost effective in the short
run, it will not add up in the end, when we find ourselves needing
to replace our F-16s say, 15 years down the road, with what? NGFs.
And of course, we would have missed out on 15 years of getting a
headstart in operating ATFs in the region, and along with it, lots
of technical expertise that would allow us to fight the air war far
better.
Can an F-16 still be on the cutting edge in the skies of the
future? No doubt it will still be high up the food chain but
certainly no longer the top dog.
In hunting for an NGF, I think the RSAF is pretty justified.
