“The Navy accepted compromises in the bow structure, presumably to save weight, during the building of these ships,” Gilmore wrote lawmakers, including Senate Armed Services Committee Chairman John McCain, in a September letter that wasn’t previously disclosed. “Multiple ships of the class have suffered damage to the bow structure.”  Read more from Bloomberg News here…
