Construction costs for the Navy’s proposed 355-ship fleet could ring in at more than $26 billion per year over 30 years, the nonpartisan Congressional Budget Office reported Monday. The Navy proposal tracks closely with President Trump’s promise to build to a 350-ship Navy.

The annual shipbuilding cost, which would dramatically increase the service’s current 275-ship fleet, is 40 percent more than what Congress approved in 2016 and dwarfs such annual ship spending over the past three decades, according to the CBO.
