I forgot the price but in the news paper about 10 years ago it cost the
military about $ 20 K just to get a diode that should have cost a couple of
dollars. The military was out of them and the manufacture had to make a run
of a few thousand . You just can not make one simiconductor.

It is not just a question about MAKING, the army must use MIL-SPEC
devices, and how do they go on making such.... They probably cannot
use an ordinary device for any reason - even in non-critical
applications. Take 2N525 , it is MIL-spec'ed, but most of them are
probably defective today and it has been much better devices to find
for the last 40 years

The difference between a mil-spec'd part and a commerical part is mainly
one of documentation. A series of tests are then specified for the
completed parts to make sure they meet their specifications. The care
imposed on the manufacturing process ensures that the parts are built
correctly. It says nothing about the robustness of the design though, it
just ensures that the design parameters are met.
