On June 3, 2003, the City proudly adopted the USS McClusky, FFG 41 as part of the America Supporting Americans (ASA) Adopt a Ship Program. The America Supporting Americans program was created to provide a mechanism whereby all branches of the United States Armed Services would be "adopted" by an American City. The purpose of the program is to bond Americans with servicemen and women who so bravely serve our country.

On February 7, 2006, the City adopted of the First Battalion of the Fourth Marine Regiment. Following the decommissioning of the USS McClusky in 2015, the City adopted the USS Stockdale, DDG-106. Both units are supported by the City's Laguna Niguel Military Support Committee.
