Question about the F-22 and it's radar.

OK this is from memory... and the sources are not strictly 'official'.

I had heard some rumours that the F-35 and F-22 AESA antennae will be
merged because the MMIC's from the F-35 will be retrofitted to the
F-22's ( they are very expensive and larger.)

The number of MMIC's may also be the same in both aircraft to make a
common 'cheap' AESA antennae (1200 IIRC).

The whole avionics suite of the F-22 is now obsolete, and will cost
another $3.5 Billion to 'upgrade' thats the cut from the $11.7 Billion
thats been bandied about.

Do you have anything to support that contention? There is a bit of a
difference between wanting to improve the computers during the spiral
development process and claiming that the "whole avionics suite is
*obsolete*", isn't there?


Just the official reports!!, Lockheed has only purchased enough
processors for 155 F-22's because there out of production, the demand
for Air to ground operations has increased the demand on processing
power, something the original processors are not quite upto hence the
_need_ for the 'upgrade'.

So the processors are obsolete, (too old)... the Avionic architecture
needs to be replaced before the F-22 can become the F/A-22 because the
present system is based on the old processors and rewriting the code
is pointless on an obsolete system, that would only support half of
the F-22 fleet

They have to go with a more COTS based system (similar to, if not the
same as the JSF), which they are working on now, for fielding in (very
optomisticlly) in 2007.

A simple analogy for you, the old 486 computer still works, but when I
wanted to run XP on it the demands of the system increased to the
point where it was useless to try, and you couldn't buy a 486
processor anywhere to support it.

I call that an 'obsolete system', it worked great running win 98.

Now the Raptor can't run the software to do its air to ground mission
for the same reasons what would you call it?. "processor
challenged???"



Out of curiousity, why do you have this visceral hatred of the F/A-22? Does
it perhaps stem from the fact that you know your own nation can never afford
it, or what?

I don't hate it, I just think its not worth the money, if it had been
half the price and worked as advertised I would be impressed.
As it is the price is $150M and development is not mature, production
has started, How would you describe the F-22 process?.

Its not a model that every industry is adopting is it.

I do not doubt that Australia can't afford it, however its looking
increasing likely that the US may join us in that.

Normally a program this far into production can't be cancelled, but
this program seems to be trying real hard...

The JSF seems (at least so far) to be much more aware of getting
development right first, then moving onto production. (and it doesn't
need the F-22 SMURFS:-))
