HUNTINGTON INGALLS INCORPORATED

Huntington Ingalls Inc. specializes in the design, construction, and post-delivery support of complex U.S. Navy surface combatants and amphibious vessels, with deep expertise in shipbuilding and repair operations at its Pascagoula, Mississippi facility. The contractor delivers full lifecycle naval platform services, including advance procurement, post-shakedown availability, modernization periods, and yard support for classes such as DDG 51, DDG 1000, LPD 17, and LHA(R). Their technical capabilities encompass integrated planning and engineering efforts, dry-dock construction, combat systems integration, and systems availability management, all executed under strict naval specifications and defense acquisition protocols. A key differentiator is their sole-source authority to perform critical post-delivery support for advanced warships, reflecting unmatched institutional knowledge and facility readiness for classified and mission-critical naval maintenance. The company maintains a sustained partnership with the Department of Defense, particularly through Naval Sea Systems Command (NAVSEA), delivering shipbuilding, repair, and lifecycle support for the U.S. Navy’s surface fleet. Additional work for the Department of Homeland Security indicates involvement in maritime security platforms, though defense programs dominate their portfolio. Their relationship with NAVSEA is characterized by recurring, mission-critical contracts requiring specialized shipyard infrastructure and security clearance. Their primary focus is NAICS 336611—Ship Building and Repairing—where they operate as a Tier-1 naval shipbuilder with vertical specialization in guided-missile destroyers, amphibious transport docks, and large-deck amphibious assault ships. They are positioned as a strategic industrial base asset for national defense, capable of end-to-end production and sustainment of high-complexity warships. Huntington Ingalls Inc. is a large-scale, multi-site defense contractor structured as a 2L entity with no public certifications listed. Its Pascagoula facility serves as a cornerstone of U.S. naval industrial capacity, anchoring its role as a primary contractor for the Navy’s most advanced surface combatant programs.
