Navy’s estimate of Columbia Class cost “not realistic”; Giant box ships face Houston Ship Channel limits

April 1oth 2019
April 10, 2019 — A GAO (U.S. Government Accountability Office) report says that the Navy’s cost estimate to construct 12 Columbia class submarines—$115 billion—is not realistic because it is based on several overly optimistic assumptions, such as the amount of labor needed for construction. The Navy has identified the Columbia class submarine program as its top acquisition priority. It plans to invest over $100 billion to develop and purchase 12 nuclear-powered ballistic missile submarines to replace aging Ohio class submarines by 2031.
