USS Lyndon B. Johnson (DDG-1002) is to be the third and final ship of the Zumwalt-class destroyer. The contract to build her was awarded to Bath Iron Works located in Bath, Maine, on 15 September 2011. The award, along with funds for the construction of USS Michael Monsoor (DDG-1001), was worth US$1.826 billion.[1][5] On 16 April 2012, Secretary of the Navy Ray Mabus announced the ship would be named Lyndon B. Johnson in honor of Lyndon B. Johnson, who served as the 36th President of the United States from 1963 to 1969. DDG-1002 is the 34th ship named by the Navy after a U.S. president.[6]

Lyndon B. Johnson is a Zumwalt-class destroyer, 32 units of which were originally planned, the U.S. Navy eventually reduced this number to three units.[7] Designed as multi-mission ships with an emphasis on land attack and littoral warfare,[8] the class features the tumblehome hull form, reminiscent of ironclad warships.[9] In January 2013 the Navy solicited bids for a steel deckhouse as an option for DDG-1002 instead of the composite structures of the other ships in the class.[10] This change was made in response to cost overruns for the composite structure, but due to the tight weight margins in the class, required weight savings in other parts of the ship.[11]
