snip all the personal slights and fluff


This is getting silly, were getting away from the major points with
little headway being made and sniping at each other is childish - What
exactly are we arguing about....


What I say..

Tthe F/A-22 program is too expensive for the uility it provides, and
has severe problems with software and avionics, and is struggling to
survive the review.

It requires several updates to software forcing an upgrade to the
hardware, which also increases costs.

I have provided sources for my assertions, (you have rubbished the GAO
credability),. while you have provided no quotable sources to rebutt
my assertions, you ignore facts, and provide no alternative but your
unsubstanciated opinion.


What You say

The F-22 is the most capable fighter in the world, its development is
comparable to a normal fighter program, there are no major problems,
its all being taken care of.

Issues of reliability, cost, obsolecence are all figments of
someones imagination.

The F-22 has JDAMS cleared for operation use, (something I wasn't
aware of!, how long ago was it cleared for the F-22)

You don't like GAO assesment of the program.



Now for some of those side issues

Ok sources - how about LM, take a look he-

http://lean.mit.edu/Events/workshops...FA22Raptor.pdf

Page eleven- 2.1 for the airframe 3.1 for the engines.

This gives an overall score to the airframe development ie 1 lowest
to 5 highest.

or Jon Ogg on obsolete systems

Try googling " ogg stsc crosstalk " I'm sure you'll find that
interesting. especially the bit about :-


"Q: Why does it cost so much to migrate to new hardware considering
that electronics technology has decreased from five-year cycles to one
year or less?

Ogg: Many of the current architectures are unique and make software
dependent on hardware. So when hardware changes, you have to redo
software at an enormous cost.

Today there is a big push on open systems and to insulate or isolate
the hardware from the functional/program software. At some future
point, the hardware component technology will change. Open systems
minimize the dependency of executing software on the underpinning
hardware. The focus is on making the system more adaptable to future
change.

In addition to the F-22 standing out as an example of this problem, we
had the F-15, F-16, B-1, C-5, and C-130 -- multi-billion-dollar
programs -- all slated for modernization. The end-user [warfighter]
wanted enhanced capabilities and functionality that couldn't be
accommodated with existing avionic architectures. So we were faced
with modernization that typically spans four to six years due to the
need to rebuild existing software for hardware technology that was out
of production."



I like the bit about the end user myself.... capability...
functionality.... can't be done on existing avionics architecture...
Sounds familier to me....
