Navy Virginia (SSN-774) Class Attack Submarine Procurement: Background and Issues for Congress [September 29, 2021] [open pdf - 2MB]
From the Introduction: "This report provides background information and issues for Congress on the Virginia (SSN-774) class nuclear-powered attack submarine (SSN) program. The Navy has been procuring Virginia-class SSNs since FY1998, and a total of 34 have been procured through FY2021. Since FY2011, Virginia-class boats have been procured at a rate of two per year. The Navy's proposed FY2022 budget requests the procurement of the 35th and 36th Virginia-class boats. A key issue for Congress concerns the SSN force-level goal and procurement rate. Decisions that Congress makes on this issue could substantially affect U.S. Navy capabilities and funding requirements, and the U.S. shipbuilding industrial base."
