I know just enough to say something stupid here, but I believe the reasons
(a) the military was experimenting with a wide range of networks and it
was already clear when the TCP/IP effort started that different
types of media had different strengths -- and the military didn't
want to risk picking the wrong one. (An impression perhaps
reinforced part way through the TCP/IP research effort by the
Autodin II effort -- which did pick one network, which the
contractor then was not able to deliver).
(b) long military refit cycles -- I spent a few years at the start
of my networking career figuring out how to attach new TCP/IP networks
in shipboard command centers to 15+ year old equipment already on
the ships. Expressed another way: the network you choose now will
be installed sometime in the next 10 years and then will be on that
ship another 20 years -- how is it going to interact (as it often
must) with equipment that's already there (and has what was then
the latest and greatest comms technology) and the technology that
is to come?
