Navy DDG-51 and DDG-1000 Destroyer Programs: Background and Issues for Congress [Updated September 29, 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. [...] 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). Other issues for Congress concern the Navy's future force-level goalfor large surface combatants (or LSCs, meaning cruisers and destroyers) and how the Navy proposes to transition several years from now from procurement of DDG-51s to procurement of a successor destroyer design now in development called the DDG(X). Decisions that Congress makes on these issues could substantially affect Navy capabilities and funding requirements, and the U.S. shipbuilding industrial base."
