Hardly a stealth profile in normal sea conditions.

Both vessels, are required to have an AIS system. I know the Navy would be operating under “stealth” mode, but the container ship would show on their system. Bridge to bridge communication should have come into play, to avoid the accident.
The AIS on my vessel is interfaced with the radar and plotter and set to 3 nautical miles. Alarms would have been sounding when another vessel entered that range.
What kind of action was taken to avoid the accident?
If the Navy ship had invisibility it had jolly well be watching out, being in a traffic zone too. Somebody slept at the helm?
