Pasting the slide here:

====================================
Ada may not be appropriate

    - When some other language has lower lifecycle costs
    - For some R&D applications where the intent is for concept
development only and the system will not be fielded
    - For some prototype applications, however the prototype must not
be carried into E&D for subsequent fielding
    - When a compiler does not exist for the hardware platform
    - When timing and/or sizing constraints make Ada a technical
infeasibility
====================================

So he specifically mentions R&D with no "fielding", where "fielding"
is probably where people's lives depend on it, in the context of DoD.

I don't think that makes sense in his context and time. The whole
comparison was C++ vs Ada. Why suddenly assume he meant some other
language on this particular slide?
