Marin,

There are a number of programs here, the F22 being one of them.  I
work on the C27J program which is a joint venture with the Italians
to upgrade their C27 transport aircraft to add the new digital
integrated
avionics package, 5000 shp Allison engines, and Dowty 6 blade props
that are used in our new C130J.  In our Avionics group, we do the 
software (all in Ada, of course) for the two mission computers and their
two backup computers which communicate with and control all the other
electronic systems on the aircraft.

There are a number of other programs here as well but at least the F22,
C120J and C27J programs are at Level 3 and moving towards Level 4.
This is mission critical software and has an estimated life of 20 years.
We also have to meet DO 178B Level A standards, ISO 9000, and a few
others.
Sometimes the process becomes a pain but hopefully it all pays off 
in the long run.

Jerry
