You might well be correct--I don't know--but having viewed the video of the same class destroyer accelerate and turn sharply at speed that someone else earlier posted a link to, I suspect it might be even worse than that.
It was reported on MSM (yeah, 'fake news'--I know) that the destroyer had 3 minutes 'warning' prior to the collision to prevent it. If I recall correctly, the destroyer in the video did a 180 degree turn in about half that time, plenty of time to take evasive action if capable of doing so, and easily enough time to avoid being t-boned.
That suggests that it was incapable, or in other words, was somehow temporarily incapacitated in many, if not all functions. That the destroyer was then able to get to port on its own power, suggests that it was a temporary and reversible condition. To me, that suggests the destroyer was somehow electronically hijacked, but who knows by whom?
As per Sherlock Holmes (and also as a self-acknowledged conspiracy realist) I wouldn't rule out ANY of the technologically capable suspects, no matter how chillingly unlikely. #sittingducks
Lastly, concerning the recent firings, I consider them to be the equivalent of sacrificial anodes, to prevent the badly corroded superstructure from failing completely and sinking, if you get my drift. #sacrificiallambs
Obviously, itís just my speculation, and I welcome othersí points of view. I'm waiting for the verbal barrage and/or better explanation, fellow sailors, and I live to learn.
