LCS production meets all milestones while the combat capable Virginia-class submarines fall to 1.4 hulls produced per year. Base Closures of the past 30 years have forced the U.S. Navy to push submarine maintenance onto private shipyards… and those shipyards stopped performing maintenance on our submarines over a decade ago. Who maintains the US Navy sub fleet? 4 shipyards and they can’t keep up. We were warned this would happen and Congress and the Navy leaders of a decade ago authorized it.
