It doesn’t seem to be the case. Looks more like dereliction of duty to me.
That is not to say the Navy may be hiding some pertinent information for politically correct reasons, or so as to avoid an international incident.
Anyway, you are certainly forgiven. But to me it doesn’t appear to be the case.
Oh I agree that someone needs to be watching outside for those elusive and hard to see 1000’ long cargo ships. Still, it seems odd to me that the warships don’t have a proximity warning system like aircraft have these days. Meaning I expect that they DO have such a system and then I wonder why it didn’t work? Was it being blinded or tampered with?
