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.
