Navy DDG-51 and DDG-1000 Destroyer Programs: Background and Issues for Congress [Updated June 4, 2021] [open pdf - 1MB]
From the Introduction: "This report presents background information and potential oversight issues for Congress on the Navy's Arleigh Burke (DDG-51) and Zumwalt (DDG-1000) class destroyer programs. The Navy began procuring DDG-51s, also known as Aegis destroyers, in FY1985, and a total of 87 have been procured through FY2021, including two in FY2021. The Navy procured three DDG-1000 class destroyers in FY2007-FY2009 and plans no further procurement of DDG-1000s. The Navy's proposed FY2022 budget requests the procurement of one DDG-51 in FY2022, rather than the two DDG-51s that are called for in FY2022 under the FY2018-FY2022 DDG-51 multiyear procurement (MYP) contract, and that were projected for FY2022 under the Navy's FY2021 budget submission. Procuring a second DDG-51 in FY2022 is the number one item on the Navy's FY2022 Unfunded Priorities List (UPL)--the service's list of programs it would prefer to be funded in FY2022, if additional funding were to become available. A key issue for Congress for the DDG-51 program in FY2022 is whether to fund the procurement of one DDG51, two DDG-51s, or some other number of DDG-51s (such as zero or three)."
