Since the Government is no longer mandating the use of Ada and programs have
mostly migrated to other platforms, what happened to all the Ada software that
the government purchased?  The reason I am asking this question, we have a
number of legacy systems and sometimes they ask that we purchase Ada products,
such as an Ada compiler.  Do inventories exist for Ada products?  Thanks--

Ada software projects and vendors have hardly become endanged species!

There are several Ada vendors active in the marketplace, among them Ada Core
Technologies, Aonix, DDC-I, Green Hills, RR software, and Rational.

Please contact any of these vendors for information regarding the acquisition
of the compilers, tools, and support necessary to support your customers. (For
a list of vendors with links to their Websites, go to

I presume you will get several answers.  In fact
there are still a significant number of projects using
Ada (e.g JTF, International Space Station, NYC subway,
Channel tunnel, many nuclear power systems, etc.).
There are several companies still actively selling
and supporting Ada compilers (for a variety of hosts
and targets), including:

   AdaCore Technologies                 --
   Aonix                                --
   DDCI                                 --
   Green Hills Systems                  --
   Irvine Compiler Corp                 --
   Rational (now part of IBM)           --
   RR Software                          --
   SofCheck, Inc. (formerly Intermetrics/AverStar/AverCom) --

There are a number of websites devoted to Ada, including the
Ada Information Clearinghouse, sponsored by the Ada Resource
Association, which may be your best starting place:

I hope this answers your questions.

As the other people here have mentioned, Ada is not dead. See and for more information on the
state of Ada.

Anyway, this is the wrong forum for this question. This mailing list is for
questions and proposals about the Ada standard itself. General questions on the
usage of Ada aren't appropriate here; they should be directed to the team-ada
mailing list (, to which I've forwarded this message) or to the
comp.lang.ada newsgroup.

"programs have mostly migrated to other platforms"

That's certainly not what we see. yes, there is some migration, but then
there are completely new projects as well.
