Navy DDG(X) Next-Generation Destroyer Program: Background and Issues for Congress [Updated August 2, 2021] [open pdf - 551KB]
From the Introduction: "The Navy's DDG(X) program envisages procuring a class of next-generation guided-missile destroyers (DDGs) to replace the Navy's aging Ticonderoga (CG-47) class Aegis cruisers. The Navy wants to procure the first DDG(X) in FY2028. The Navy's proposed FY2022 budget requests $121.8 million in research and development funding for the program. The issue for Congress is whether to approve, reject, or modify the Navy's FY2022 funding request and emerging acquisition strategy for the program."
