GAO: Navy “Overly Optimistic” On Columbia Sub Costs

The Navy's most expensive shipbuilding program and the key to the country's nuclear triad is under increasing pressure to keep to its tight schedule, and hit its budget.

Current Navy plans call for construction on the first of 12 Columbia-class nuclear-armed submarines to begin in 2021, with an overall price tag of $128 billion. But the GAO’s latest audit of the program found that the Navy both failed to account for typical shipbuilding cost increases, and the complexity of actual “hands-on” labor hours it will take to build the boats.

GAO didn’t venture its own estimate, but it cited a study by its sister agency, the Congressional Budget Office, that the Columbia program might cost almost $145 billion — 13 percent above the Navy figure.
