Google USS Fitzgerald as well as Fat Leonard, that will put you on the path to understanding the pervasive problems in 7th fleet. They've chopped off heads in leadership, so maybe things are moving towards better, but it's undeniable there's been a huge problem festering for ages.

Familiarize yourself with the Zumwalt and LCS procurement programs. Both are nearly total failures, with the Navy grasping at straws to find ways to make the ships that have been constructed useful. Congress bears some of the blame here, particularly in relation to Zumwalt, but it's also clear Navy leadership has been often incompetent in planning future acquisitions. Those two programs cost US tax payers about $50 billion.
