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

In British Telecom we had to use CV-numbered semiconductors, although
we could use normal types in the IMTR labs, but it should be
equivalent for a CV-numbered device, the only one I remember now - 25
years later is CV7127. Fortunately not so stupid in Norwegian Telecom
