C has been known to control big, expensive hardware. One such
example is the mutinode Deep Blue capable of searching a few million
nodes per second. Is the speed critical in this project? If so, I see
on reason to avoid Ada that checks every shift, rotate, add, multiply
in your software.

Maybe you could try to sell the safety critical side of Ada. But
software that does not get tested will crash, kill, dump core, etc...
