Re: Safety-Critical Systems Developed Using C++

Not entirely true. The DoD doesn't get into approving languages for use -
they simply make the contractor justify their choice.

I hear tell that the THAAD program is going to be getting done in C++. I
think this is a mistake - for reasons of safety - but the program
management seems to think that if this is what the rest of the world does
then they should be doing it too. (And I can hear my mother in the
background saying "...so if Johnny decides to jump off a cliff, are you
going to do it too???" :-)

Windows as a foundation for a safety critical real-time app would be a bad
idea. You can't guarantee latency and priority with Windows. I've seen
Windows add-ons (see: http://www.vci.com/ for example) where someone wrote
a real-time OS that executes Windows as an application. Then you might be
O.K.
