The simple truth of the matter is that the US surface Navy has, for the last 20 some years, been deferring maintenance and training of its core assets in order to fund prestige projects like the super carriers. 7th fleet is particularly egregious on this front, but this comes down to a resource allocation issue. Congress and the admiralty have shrunk the surface Navy, and forced the existing fleet to "do more with less." What this means is a higher operational tempo, with no down time, no repair schedule, and no training. In the investigation into the most recent destroyer crash, the board found that the bridge crew hadn't been trained on the basics of navigation, but rather on the basics of how to operate the computer system that navigated for them. Additionally, because of man power constraints, where junior officers would once spend the first few months of their career shadowing a senior officer, now they're thrown into command of a watch with no physical training, just a stack of DVDs they're supposed to go through before deployments.
It's an embarrassment, but it's an embarrassment of command, not to the sailors who are trying to make do with no time to do their jobs.
