From what I understood the recent Navy collisions are caused by under-staffing => sailors having to work too long days => sailors literally falling asleep at their posts / seeing things that aren't there / not seeing things that are there

They seem to work twelve on, twelve off, with requiring that some of their personal time being used to maintain physical fitness, so does seem like a disaster waiting to happen.

There is zero evidence of enemy tampering in recent Navy ship collisions / allisions. It was simple incompetence and bad luck. There's really no way to tamper with shipboard surface radars, binoculars, horns, and VHF radios. As long as that equipment is working correctly all collisions can be avoided.
