>>Ummm, what was the ‘series of missteps’? That’s what people want to know...<<
Try googling. I recall reading a decent explanation of the series of missteps several month ago. The Navy released details.
As I recall, primary steering was suddenly mucked up and was transferred to a different station that could have corrected the situation, but the transfer order wasn’t understood properly and mistakes multiplied from there. (all of the above is in non-Navy talk, including “mucked up,” by the way.)
The report...Singapore Safety Report on USS John S. McCain Aug. 21, 2017 Collision
Read it for yourself to know.
Perhaps the professional negligence is based in part on the fact that once navigation was in jeopardy it would have been prudent to slow or even stop while at the same time assuring a sufficient number of lookouts.
Thanks...
