Unlike the previous two Arleigh Burke-class ships USS Jack H. Lucas (DDG-125) and USS Louis H. Wilson Jr. (DDG-126) which were inserted into the previous multi-year contract and are planned to be built in the Flight III configuration, Patrick Gallagher was separately added to Navy shipbuilding plans by Congress and will be built in the Flight IIA configuration.^[8][9] Bath Iron Works was awarded the contract for Patrick Gallagher on 28 September 2017^[10] and construction started on 9 November 2018.^[11] On 30 March 2022, her keel was laid down at Bath Iron Works.^[2]

The ship was christened at Bath Iron Works shipyard on 27 July 2024. US Senator Susan Collins of Maine was in attendance.^[3] Outside the north gate, a group of around 75 protesters of the Gaza war were blocking roads, criminal trespass and dumping red liquid on the area in front of BIW's main building. Several were arrested.^[12]
