Navy DDG-51 and DDG-1000 Destroyer Programs: Background and Issues for Congress [April 16, 2018] [open pdf - 1MB]
"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 procured DDG-51s from FY1985 through FY2005, and resumed procuring them in FY2010. The three DDG-51s requested for procurement in FY2019 are to be the 80th, 81st, and 82nd ships in the class. The Navy procured three DDG-1000s in FY2007-FY2009 and plans no further procurement of DDG-1000s. The 13 DDG-51s planned for procurement in FY2018-FY2022 are to be procured under a multiyear procurement (MYP) contract that Congress approved as part of its action on the Navy's FY2018 budget. DDG-51s procured in FY2017 and subsequent years are being built to a new design (the Flight III DDG-51 design), which incorporates a new and more capable radar called the Air and Missile Defense Radar (AMDR) or SPY-6 radar."
