Heavy machine gun fire direct to bridge killing the command crew.
It might be the Iranians have figured out how to hack the computerized controls.
I believe the AIS code is NUC, or “Not Under Command”. Technically, this code should be used when you have a loss of steering, throttle or propulsion and cannot maneuver, or “command” the ship. But, it’s not that uncommon for ships just drifting offshore waiting to pull into port to set their AIS to NUC. They are telling ships in the area that they are not able to maneuver. In many cases, there is no one on the bridge capable of maneuvering the ship. I believe this is a misuse of AIS, but I’ve seen it a lot.
It’s possible the ship’s AIS was transponding NUC when they were boarded, and this code had nothing to do with the boarding, hijacking or whatever is happening.
