I got an MSCS from the Naval Postgraduate School when Ada was "required" for all DoD projects, so it was the intro programming language then. I haven't touched it since 1993, so I can't comment on current version of it, but there are still several people at NPS who swear by it, and, as another commenter said, it is an Apple level of fanboy-ism. Anyone who doesn't like Ada just doesn't get it and needs to be preached to.
The main argument for Ada is that it contains many mechanism to prevent errors, so that the code produced will be much safer and reliable, and thus should be used in any system where failure causes significant problems, i.e., aircraft, weapons, etc.
There was one faculty member at NPS who would send an e-mail any time a military project was held up by software delays and basically say, "Had they used Ada, this wouldn't have happened." No acceptance of the fact that Ada doesn't protect against logical errors, or that since the libraries are much scarcer than other languages, they probably wouldn't have gotten anywhere near completion had they used Ada. Not to mention needing pretty much EVERY Ada programmer on the planet for any project bigger than "Hello World."
