About the company
HII Fleet Support Group LLC, a division of Huntington Ingalls Inc., the nation's largest military shipbuilding company, delivers engineering, technical maintenance, and logistics support for naval vessels and shore facilities as a prime contractor on full-and-open Naval Sea Systems Command (NAVSEA) and Naval Information Warfare Systems Command (NAVWAR) vehicles, with no small business set-aside certifications. The Virginia Beach–headquartered division competes across cost-plus-fixed-fee and firm fixed-price delivery orders, anchoring its portfolio to carrier engineering maintenance assistance, hull and mechanical electrical systems engineering, C4ISR installations, and surface fleet readiness operations across Nimitz-class and Gerald R. Ford-class carriers, guided-missile destroyers, submarines, and amphibious platforms.
HII Fleet Support Group's customer base concentrates heavily in naval commands. The top five funding agencies account for 92 percent of recent awards: Naval Sea Systems Command leads with 2,708 awards valued at $4.54 billion combined potential value, followed by Naval Information Warfare Systems Command with 801 awards and $2.44 billion, then Navy Pacific Fleet Forces (615 awards, $270.2 million), Navy Fleet Forces Command Atlantic (511 awards, $229.8 million), and Army TACOM Life Cycle Management Command (9 awards, $190.1 million). Dollar concentration is even steeper—NAVSEA and NAVWAR together represent approximately 87 percent of combined potential value. The division also executes work under U.S. Fleet Forces Command through a $48.45 million Engineering Maintenance Support IDIQ extending through May 2027.
HII Fleet Support Group holds substantial NAVSEA vehicle positions. The Engineering and Technical Services IDIQ (Contract N00024-21-D-4114) carries a $496.1 million ceiling extending through July 24, 2029, and has generated 569 task orders under HII Fleet Support Group execution, serving as the parent vehicle for recurring carrier engineering maintenance assist team (CEMAT) and surface engineering maintenance assist team (SEMAT) labor and technical repair work. The Engineering and Support Services for Hull, Mechanical and Electrical Systems IDIQ supports mass modification work, voyage data recorder installations, and specialized systems engineering across multiple ship classes. HII Fleet Support Group also holds positions on the SPAWAR Afloat C4ISR Installations 2019 IDIQ issued by NAVWAR for command, control, communications, and reconnaissance hardware installations across submarines, surface combatants, and mine countermeasures vessels, and operates under Army Watercraft Sustainment Maintenance–Zone 3 (AWSM) for unprogrammed repairs to Army Landing Craft Utility vessels at Virginia Beach.
Recent representative prime work includes a $17.36 billion delivery order (July 2025) for CEMAT support during USS John C. Stennis (CVN-74) refueling and complex overhaul, a $22.06 million order (January 2025) for elevator support unit operations across Nimitz-class carriers, a $28.79 million order (August 2025) for CEMAT labor support across multiple carriers including racks and ovens work, a $14.65 million order (August 2025) for elevator support unit staging and repair aboard CVN-74, and a $12.52 million order (July 2025) for surface engineering maintenance assist team task order 24-M1507 with air compressor, HVAC, and pneumatic systems work. Activity has grown from 61 awards in 2022 to 107 in 2025. Awards with ultimate completion inside the next twenty-four months total 29 with combined potential value of $126.9 million, presenting recompete exposure concentrated in NAVSEA and NAVWAR vehicles.
HII Fleet Support Group operates predominantly as prime (98 percent of awards) and builds substantial internal delivery teams with targeted subcontracting for specialized trades and engineering disciplines. Across SCI-reportable prime contracts, subcontractors performed approximately 7 percent of total contractor hours. The division engages recurring named subcontractors including Tecnico Corporation (hull, mechanical, electrical repair), Delphinus Engineering (shipboard labor and SUBSAFE work), Life Cycle Engineering (technical repair and engineering support), QED Systems (ship maintenance), Epsilon Systems Solutions (ship maintenance and repair), Noblis MSD (technical program management), Colonna's Ship Yard (structural and elevator repair), and smaller specialists for welding, rigging, HVAC, ventilation cleaning, and materials handling. SCI-reported invoiced revenue declined from $9.1 million in FY2022 to $2.8 million in FY2025 across 19 to 50 FTEs; government-paid rates on prime SCI contracts ranged from roughly $53/hour at the 10th percentile to $166/hour at the 90th percentile, with a median of approximately $114/hour. The division also subcontracts to major defense primes including Huntington Ingalls Inc. (parent), The Boeing Company (XLUUV/ORCA systems design work), Northrop Grumman (gun mission modules), and BAE Systems (labor funding and material support on various task orders), demonstrating capacity as a feeder to larger enterprise programs while maintaining core NAVSEA prime relationships.
