Based on current construction performance, the Navy reported in April 2024 that the first (lead) Columbia class submarine is estimated to be delivered 12 to 16 months after its originally planned date. This would result in delivery between October 2028 and February 2029. A late delivery could ultimately jeopardize the lead submarine’s planned availability for operations in 2030.

According to GAO’s analysis of program data from January 2022 through May 2023, cost and schedule performance for lead submarine construction has consistently fallen short of targets. Through early 2024, those trends had not improved, and future risks will likely add to current cost and schedule growth. The program has reported that the shipbuilder needs to take swift and significant actions to address the causes of poor construction performance. However, as GAO has previously reported, the program has tried to mitigate some of these causes—such as late materials and detailed design products—for years.
