these accidents are starting to smell like that to me. i bet the lower down in rank you get in these incidents the clearer the peril and the greater clarity about exactly what should have been done.
it can not possibly be lack of nav info, my guess is the nav station is awash in really good info on collision and target tracking.
On a typical navel vessel their are 6 to 10 people ( McCain had 12) performing the same task and reporting up the chain to a commander who makes decisions to maneuver down through the chain. What could possibly go wrong?
I operated many types of oilfield support vessels in all weather and high traffic areas. You must have a comprehensive situational awareness and be able to react to unusual situations in seconds. My opinion is that reaction time and judgement is compromised through the military mind set. When seconds count you cannot wait for someone to come on the bridge, acquire situational awareness and make a judgement call to tell a group of sailors to turn the helm and reverse one or more throttles. That sets up a cluster that might be to late anyway.
