You seem to be right about the Navy. As an example, I looked at the information at http://www.chinfo.navy.mil/navpalib/factfile/ships/ship-dd.html. They don't just use inch-pound units in the primary position. They also show the metric conversions with a ridiculously high degree of precision -- a tactic common among those who want to discredit SI. As to your more general question, I'll leave that to others more knowledgeable in the military area. Bill Potts, CMS Roseville, CA http://metric1.org [SI Navigator]
