Navy DDG(X) Next-Generation Destroyer Program: Background and Issues for Congress [Updated March 31, 2022] [open pdf - 564KB]
From the Document: "The Navy's DDG(X) program envisages procuring a class of next-generation guided-missile destroyers (DDGs) to replace the Navy's Ticonderoga (CG-47) class Aegis cruisers and older Arleigh Burke (DDG-51) class Aegis destroyers. The Navy wants to procure the first DDG(X) in FY2028. The Navy's proposed FY2022 budget requested $121.8 million in research and development funding for the program. [...] Issues for Congress regarding the DDG(X) program include the following: (1) whether the Navy has accurately identified the DDG(X)'s required operational capabilities and estimated procurement cost; (2) the DDG(X) program's potential total procurement quantity and annual procurement rate; (3) the number of shipbuilders to be used in building DDG(X)s; (4) the Navy's plan for maturing new technologies for the DDG(X); and (5) the Navy's plan for transitioning from DDG-51 procurement to DDG(X) procurement, and the potential impact of that transition on shipbuilders and supplier firms. [...] The Navy's proposed FY2022 budget requested $121.8 million in research and development funding for the program, including $79.7 million in Project 0411 (DDG[X] Concept Development) within Program Element (PE) 0603564N (Ship Preliminary Design & Feasibility Studies), which is line 47 in the Navy's FY2022 research and development account, and $42.1 million for 'DDG(X) Power & Propulsion Risk Mitigation & Demonstration,' which forms part of Project 2471 (Integrated Power Systems [IPS]) within PE 0603573N (Advanced Surface Machinery Systems), which is line 49 in the Navy's FY2022 research and development account."
