    I had some answer in mind until I saw the "in military application" part. The military (I assume you are referring to the U.S. Military) goes out of their way to re-invent the wheel on everything. FTDI, as previously mentioned, would have been my answer, but because that's so simple, I would have to assume that FTDI is not what the miltary uses. They probably payed some government contractor to design some off the wall gadget and test it over a span 10-15 years before installing it.

    However, as I was leaving the military I started to notice a gradual shift toward acceptance of what they call COTS (common off the shelf) parts used in military applications, so who knows.

    I'm still not 100% sure what you want. If you are looking for a USB>Serial converter that is MILSPEC (meeting standards established by the military for military applications) then search for a MILSPEC USB>Serial converter. I was not able to find any, but I only looked for about 5min; not my project. If you want to hear of specific instances where the military employs USB>Serial converters, then search something like "USB>Serial converter military application" but you probably won't find anything because the military doesn't advertise how they do things.

    Go Google MIL-STD-1553, it is the serial bus the military uses in jets, it controls the wire in fly by wire. Well... not really, but it does arm the bombs.

    Company I work for makes transceivers for it.

    Been around since the 70's or 80's.

    They are not cheap.

    Anywhere where they need to connect to a serial bus and have only usb available. It may be used in offense too.

    Just so we keep our terms accurate, RS232 is serial but it's not a bus.
