“Realizes from AIS they just passed a USN”
There has been no indication the Fitz had it on from what I’ve found. USN ships track AIS but wouldn’t broadcast it for obvious reasons.
I would agree. I monitor ship traffic from my house on the BI of Hawaii all the time. You will see AIS IDs of navy ships sometimes, usually near Pearl Harbor, never out at sea.
Watched the RIMPC operations west of here last year on AIS and a number of foreign ships that were part of the execise had theirs on, but no US navy.
