HII’s Ingalls Shipbuilding division and the U.S. Navy’s Supervisor of Shipbuilding, Conversion and Repair Gulf Coast (SUPSHIP GC) broke ground on November 10, 2026, on a 101,000-square-foot customer support complex in Pascagoula, Mississippi, HII announced. The $50 million facility, funded through a partnership between the Navy and Ingalls, will consolidate the Navy oversight workforce assigned to some of the service’s highest-priority surface combatant and amphibious programs. Completion is scheduled for June 2028.

The project lands in the middle of a dense production cycle at the yard. HII announced on November 3, 2026, that the amphibious transport dock Harrisburg (LPD 30) had completed builder’s trials ahead of a planned delivery this year, while the amphibious assault ship Bougainville (LHA 8) and the Flight III guided-missile destroyer Jeremiah Denton (DDG 129) are both slated for delivery in 2027, according to the company. Every one of those hulls must clear SUPSHIP GC before the Navy accepts it. HII reported a corporate backlog of $86.2 billion at the end of the third quarter of 2026.

How SUPSHIP Gulf Coast Oversees Navy Construction at Ingalls Shipbuilding

SUPSHIP GC is an Echelon III field command of Naval Sea Systems Command (NAVSEA) and acts as the Navy’s on-site contracting authority at private Gulf Coast shipyards. It administers Navy shipbuilding contracts across Mississippi, Louisiana and Alabama, and its more than 600 military and civilian personnel handle engineering, quality assurance, contract management and financial oversight from construction start through delivery. The command was formed in 2003 by merging separate SUPSHIP organizations in Pascagoula and New Orleans, and NAVSEA describes it as the largest and most geographically dispersed of its four new-construction field activities.

At Ingalls, that oversight covers three ship classes running in parallel: Arleigh Burke-class (DDG 51) Flight III destroyers, San Antonio-class (LPD 17) amphibious transport docks and America-class (LHA 6) amphibious assault ships. The amphibious line alone includes Bougainville, Fallujah (LHA 9), Harrisburg, Pittsburgh (LPD 31) and Philadelphia (LPD 32), with LPD 33 through LPD 35 and Helmand Province (LHA 10) under contract since September 2024. The yard also completed builder’s sea trials on USS Zumwalt (DDG 1000), in Pascagoula for modernization, earlier in 2026.

Capt. Randy Slaff, who took command of SUPSHIP GC in August 2023, framed the building in delivery-speed terms. “Our job at SUPSHIP is to collaborate with our industry partners and deliver warfighting capability to the Navy at speed,” Slaff said. “Shipbuilding is a national imperative, and this project will bring our team together under one roof, driving efficiency and strengthening alignment as we support shipbuilding across the Gulf Coast.”

Inside the $50 Million Complex: Funding, Site and 2028 Timeline

The complex will rise on property leased from the Port of Pascagoula and will primarily house SUPSHIP GC personnel already based in the city. HII has not disclosed how the $50 million cost is divided between the Navy and Ingalls, the facility’s internal layout, or whether Ingalls program staff will share workspace with Navy personnel. Those details will determine whether the project creates a genuinely integrated government-contractor hub or primarily modernizes Navy office space next to the shipyard.

“By bringing our government partners together, we are strengthening collaboration, improving efficiency and enhancing our ability to deliver the high-quality ships our sailors depend on,” said Eric Crooker, Ingalls vice president of program management.

Attendees at the ceremony included Pascagoula Mayor Jay Willis, Ken Taylor of the Jackson County Board of Supervisors, Jackson County Development Foundation chief executive Mary Martha Henson and Port of Pascagoula Director Charles Tillotson. Ingalls is Mississippi’s largest manufacturing employer.

Analysis: The complex adds administrative infrastructure, not production capacity, but it targets a recognized friction point in Navy shipbuilding: how quickly government engineers, inspectors and contracting officers can review work, adjudicate deficiencies and accept test results. A NAVSEA web page archived in early 2013 put SUPSHIP GC at 400 personnel, against more than 600 today, an expansion that tracks the growing number of concurrent hulls in Pascagoula. Consolidating that workforce is a modest outlay relative to the value of the programs it supervises. Its effect on schedules, however, will be difficult to isolate and cannot materialize before mid-2028.

Construction is set to run through June 2028, which means SUPSHIP GC will oversee the acceptance of Harrisburg, Bougainville and Jeremiah Denton from its current facilities. Open questions include the Navy-Ingalls cost split, whether contractor personnel will be co-located in the building, and whether NAVSEA pursues similar projects at its other new-construction supervisors in Bath, Groton and Newport News.
