Navy Shipyards: Actions Needed to Address the Main Factors Causing Maintenance Delays for Aircraft Carriers and Submarines, Report to Congressional Committees [open pdf - 4MB]
From the GAO (Government Accountability Office) Highlights: "For fiscal years 2015 through 2019, the Navy spent $2.8 billion in capital investments to address shipyard performance, among other things. However, the shipyards continue to face persistent and substantial maintenance delays that hinder the readiness of aircraft carriers and submarines. The Senate Armed Services Committee, in a report accompanying a bill for the National Defense Authorization Act for Fiscal Year 2019, included a provision for GAO to review Navy shipyards' performance. GAO evaluated the extent to which the Navy (1) completed maintenance at its shipyards on time on aircraft carriers and submarines in fiscal years 2015 through 2019, (2) has identified the main factors leading to maintenance delays, and (3) has addressed the main factors affecting any delays in that maintenance. GAO reviewed data related to Navy shipyard maintenance for fiscal years 2015 through 2019, analyzed factors contributing to delays and plans to address them, visited all four Navy shipyards, and met with Navy and shipyard officials."
