Navy Ships: Timely Actions Needed to Improve Planning and Develop Capabilities for Battle Damage Repair, Report to Congressional Committees [open pdf - 2MB]
From the Highlights: "The ability to repair and maintain ships plays a critical role in sustaining Navy readiness. After the Cold War, the Navy divested many wartime ship repair capabilities. With the rise of great power competitors capable of producing high-end threats in warfare, the Navy must now be prepared to quickly salvage and repair damage to a modern fleet. House Report 116-120, accompanying a bill for the National Defense Authorization Act for Fiscal Year 2020, included a provision for GAO [Government Accountability Office] to assess the Navy's efforts to identify and mitigate challenges in repairing battle-damaged ships during a great power conflict. GAO's report (1) discusses the challenges the Navy has identified in using its regular maintenance capability for battle damage repair, and (2) evaluates the extent to which the Navy has begun developing the battle damage repair capability it requires to prevail in a great power conflict."
