Is it possible that someone is in fact utilizing GPS "hacking" that is assisting in the likelihood of these collisions? I believe there was a story here on hckrnews about GPS "hacking" last week, although most people said the issue was known and not that big of a deal.
The Fitzgerald's captain was relieved of command and other sailors would be punished after the Navy found poor seamanship and flaws in keeping watch contributed to the collision, the Navy announced last week.
