Naval Sea Systems Command awarded an indefinite-delivery contract to HII Fleet Support Group LLC on July 15, 2021, with a ceiling value of $493.632 million for Carrier Engineering Maintenance Assist Team and Surface Ship Engineering Maintenance Assist Team labor and materials, including Elevator Support Unit services. This is a single-award contract with no set-aside.

Work is performed worldwide across multiple naval installations: Norfolk, San Diego, Bremerton, Everett, Mayport, Pearl Harbor, Sasebo, and Yokosuka, with administrative oversight at various NAVSEA facilities. The originating solicitation sought engineering, technical, repair, and logistics support to aircraft carriers and surface ships, emphasizing capability to manage multiple simultaneous maintenance availabilities and rapidly respond to emergent requirements. Period of performance runs through February 16, 2027.

HII Fleet Support Group is a subsidiary of Huntington Ingalls Industries, the nation's largest military shipbuilding company, and competes full-and-open with no SBA certifications. Recent task-order activity under this IDIQ reflects sustained customer demand: delivery orders issued through April 2026 span Carrier Engineering Maintenance Assist Team support for USS Harry S. Truman (CVN-75) refueling complex overhaul ($5.89 million, September 2025), USS John C. Stennis (CVN-74) refueling complex overhaul ($17.36 million, July 2025), carrier sanitary overhaul and repairs ($4.88 million, December 2025), Surface Engineering Maintenance Assist Team support across Pacific Fleet surface combatants including USS Rafael Peralta, USS Rushmore, and USS San Diego ($8.27 million, July 2025), and Carrier Engineering Maintenance Assist Team Year 5 support to USS Harry S. Truman ($3.86 million, April 2026). Performance locations include Newport News and Hampton, Virginia; San Diego, California; and Japan-homeported carriers. Subcontractors on recent orders include Tecnico Corporation, Delphinus Engineering, QED Systems, Epsilon Systems Solutions, Life Cycle Engineering, Noblis MSD LLC, and Rocky Mountain Hydrostatics, providing specialized hull, mechanical, electrical, and HVAC systems expertise.
