HII Fleet Support Group LLC

HII Fleet Support Group LLC, a subsidiary of Huntington Ingalls Industries Inc., provides engineering, technical maintenance, and logistics support services for U.S. Navy naval vessels and shore facilities as a prime contractor (98% of recent awards) with no set-aside posture. The division is headquartered in Virginia Beach, Virginia, and competes full-and-open across Naval Sea Systems Command (NAVSEA) and Naval Information Warfare Systems Command (NAVWAR) indefinite delivery vehicles anchoring the majority of its federal work.

HII Fleet Support Group's customer concentration is heavily weighted to Navy engineering and maintenance customers. The top five funding agencies account for 92% of recent awards: Naval Sea Systems Command leads with 2,714 awards worth $8.52 billion combined potential value, followed by Naval Information Warfare Systems Command with 805 awards worth $6.86 billion, the Department of the Navy broadly with 729 awards, U.S. Pacific Fleet Forces with 615 awards worth $270.2 million, and U.S. Fleet Forces Command (Atlantic) with 511 awards worth $229.8 million. The concentration is extreme—NAVSEA and NAVWAR together represent approximately 60% of all awards and roughly 87% of combined potential value across the recent portfolio.

Capability delivery centers on carrier engineering maintenance assistance, hull and mechanical electrical systems engineering, C4ISR hardware installations, elevator support unit services, and surface fleet readiness operations. Representative recent work includes a $17.4 million delivery order from NAVSEA for Carrier Engineering Maintenance Assist Team (CEMAT) labor support to USS Harry S. Truman (CVN-75) refueling complex overhaul with advanced planning; a $14.6 million NAVSEA delivery order for elevator support unit services supporting USS John C. Stennis (CVN-74) refueling complex overhaul; a $11.4 million NAVSEA delivery order for elevator support unit technical repair and advanced planning on USS Harry S. Truman (CVN-75) with subcontractors Colonna's Ship Yard and Main Industries; and a $6.2 million Naval Information Warfare Systems Command delivery order for C4ISR installations aboard USS Nitze (DDG-94) with subcontractors including Glotech, Tecnico Corporation, and Valkyrie Enterprises.

Vehicle position reflects deep NAVSEA embedding. The top parent vehicle, a $496.1 million multiple-award Indefinite Delivery Contract for Engineering and Technical Services supporting Code 41/43 divisions (extended through July 24, 2029), carries 569 task orders under HII Fleet Support Group; two related NAVSEA IDIQs—the Engineering and Support Services for Hull, Mechanical and Electrical Systems vehicle and the HM&E Modernization Program—collectively support hundreds of task orders. HII Fleet Support Group also holds a $266.5 million multiple-award Indefinite Delivery Contract awarded July 24, 2025, by Naval Education and Training Command for Naval Training Products and Services, extending through January 31, 2031, covering training development, curriculum planning, and simulation delivery. Naval Information Warfare Systems Command's SPAWAR Afloat C4ISR Installations 2019 IDIQ is a secondary vehicle generating substantial C4ISR installation task orders. Over the past five years, annual award volume has grown from 63 awards in 2022 to 109 in 2025, indicating sustained customer demand.

Activity trajectory shows steady growth. Awards per year increased from 63 in 2022 to 98 in 2024 to 109 in 2025—a 73% rise over the period. The recompete cliff is moderate: 44 awards with ultimate completion dates in the next twenty-four months carry combined potential value of $169.8 million, representing routine delivery order churn rather than a single-vehicle re-compete risk.

On federal service contracts captured in the Service Contract Inventory, HII Fleet Support Group reported $18 million in SCI-reportable invoiced revenue across FY2022 through FY2024 (FY2022: $9.1 million, FY2023: $5.8 million, FY2024: $3 million). SCI-reported workforce scaled from 64.6 FTEs in FY2022 to 34.4 FTEs in FY2024 across prime and subcontractor records combined. Government-paid hourly rates on federal services contracts ran median around $144/hr, with senior labor pricing through $165.70/hr at the 90th percentile. Across SCI-reportable prime contracts, subcontractors accounted for approximately 7% of total contractor hours, and the division engaged 11 named subcontractors across the SCI dataset. This modest sub-hours share reflects HII Fleet Support Group's model of building substantial internal delivery teams rather than relying on subcontractor-heavy execution; when subcontracting occurs, the division engages firms including Tecnico Corporation, Delphinus Engineering, QED Systems, Noblis MSD LLC, Epsilon Systems Solutions, Life Cycle Engineering, and various small businesses specializing in marine repair and HVAC services.

Teaming pattern across prime work is predominantly in-house execution with targeted subcontracting. The 98% prime split shows HII Fleet Support Group operates as a direct prime contractor across NAVSEA and NAVWAR vehicles rather than functioning as a feeder subcontractor. Where the division does subcontract—across representative delivery orders—named subs typically provide specialized trades (welding, electrical, HVAC, lagging, structural fabrication) or engineering discipline expertise rather than program management or systems integration, positioning HII Fleet Support Group as the systems integrator and prime relationship manager with the Navy customer. The division subcontracts to established small business maritime specialists (Tecnico, Delphinus, QED Systems), staffing providers (Aerotek, Insight Global, Leed Staffing), and component suppliers (Rockwell Automation, AFP Industries, Colonna's Ship Yard), and has demonstrated willingness to engage minority-owned, 8(a), and women-owned small business subcontractors (Glotech, JRF Ship Repairs, Greentoes GRP & Coatings, Ems Ice).

As a division of Huntington Ingalls Industries—the nation's largest military shipbuilding company—HII Fleet Support Group operates at scale and carries no SBA set-aside certifications; all of its federal work is full-and-open competition on Navy vehicles. The division also subcontracts to prime contractors including The Boeing Company (XLUUV/ORCA system design work), Northrop Grumman Systems Corporation (gun mission modules), BAE Systems Technology Solutions & Services Inc., Huntington Ingalls Incorporated (parent), and others, representing a secondary role on select defense programs. However, the overwhelming majority of HII Fleet Support Group's footprint is Navy direct prime work under NAVSEA and NAVWAR IDIQs, making the division a core Navy fleet support contractor rather than a sub-dependent or transactional subcontractor to larger primes.
