On 15 January 2009, Huntington Ingalls Industries (HII) Northrop Grumman Shipbuilding was awarded a $374 million contract for design work and construction preparation for John F. Kennedy. On 30 September 2010, Northrop Grumman announced that preparations were under way to begin construction. On 25 February 2011, the Navy conducted the First Cut of Steel ceremony at Northrop Grumman in Newport News, signalling the formal start of construction for John F. Kennedy.John F. Kennedy was originally planned to be completed in 2018. This was extended to 2020 after Secretary of Defense Robert Gates announced in 2009 that the program would shift to a five-year building program so as to place it on a "more fiscally sustainable path". By late 2012, delays had occurred in construction, and the Navy Department was investigating extending the construction time of both Enterprise and John F. Kennedy by an additional two years which could delay the carrier's entry into service until 2022. In September 2013, the Government Accountability Office recommended delaying the detail design and construction contract for John F. Kennedy until programmatic shortfalls are sorted out. The Navy and Defense Department have rejected the recommendation. The Navy faces technical, design, and construction challenges to completing Gerald R. Ford, including producing systems prior to demonstrating their maturity to meet required installation dates. Gerald R. Ford had costs increase by 22% to $12.8 billion, and additional increases could follow due to uncertainties facing critical technology systems and shipbuilder under performance. Risk is introduced in the Navy's plan to conduct integration testing of key systems at the same time as initial operational test and evaluation. One action the GAO says could be taken to ensure Ford-class carrier acquisitions are supported is conducting a cost-benefit analysis of required capabilities and associated costs.The ship's keel was laid in Newport News, Virginia on 22 August 2015.  As part of the traditional keel laying ceremony, the initials of ship sponsor Caroline Kennedy, daughter of President Kennedy and the sponsor of the previous John F. Kennedy, were welded into the ship's hull. As of late June 2017 the ship was 50% structurally complete. On 28 February 2018, Huntington Ingalls Industries announced that its Newport News Shipbuilding division had built 70% of the structures necessary to complete John F. Kennedy. On 30 April 2018, Huntington Ingalls Industries announced that she was "75 percent structurally erected and more than 40 percent complete." As of the release date, 341 of the 447 super-lift sections were currently in place. The ship is scheduled to be christened in the latter half of 2019, commissioned in 2020, On 3 May 2018 Huntington Ingalls President & CEO Mike Petters reported that John F. Kennedy was tracking to be launched three months ahead of schedule in the fourth quarter of 2019. On 30 May 2019 the 588 ton bridge and island was installed completing the ship and placing the final piece of the puzzle on deck. Under the island Captain Todd Marzano placed his wing and the first Kennedy half dollar which was donated by Caroline Kennedy was put in place. Caroline could not make it so she had  Lee Murphy gave the order via radio for the crane operator to lift the island and set it down on the deck crushing the ceremonial items and entombing them in the ships superstructure completing the ship.
