    AIS on Navy ships
    From: Lu Abel
    Date: 2017 Jun 24, 16:37 +0000
    Here's a question for people (such as recent US Navy veterans) with direct knowledge:

    I can understand why naval vessels (of any nationality) do not broadcast AIS data even though commercial ships are required by law to broadcast AIS.   After all, we don't want drug smugglers or the Iranians or whoever else to know the position of US naval vessels.

    But do Navy ships receive AIS broadcasts and plot the positions of AIS-equipped vessels -- and sound a collision alarm if the CPA is too close??

    Having just said "wait for the official inquiries" I'll have to admit I wonder about whether this way for the Fitzgerald to "spot" the container ship would have been available on its bridge.
