About this IDV
The Naval Sea Systems Command awarded an indefinite-delivery contract to Fathom 4 LLC, a service-disabled veteran-owned small business, on January 2, 2019, under the Seaport Next Generation (Seaport-NXG) program with a $10 billion ceiling. This is a multiple-award vehicle with no set-aside at the IDIQ level, though individual task orders carry SDVOSB and other set-aside designations.
Seaport-NXG procures engineering, technical, and programmatic support services across twenty-three functional areas supporting the Department of the Navy and Marine Corps. The contract covers C4ISR engineering, integration, and technical sustainment work with a base ordering period of five years plus an option for five additional years, extending through January 1, 2029. NAICS 541330 (professional, scientific, and technical services) is the primary classification.
Place of performance spans multiple South Carolina locations, including Cainhoy, North Charleston, and Hanahan, with work supporting naval platforms and defense systems across the continental United States.
Recent task-order activity demonstrates heavy Marine Corps engagement. The Marine Corps issued two large sensing and information operations orders on February 17, 2026—one valued at $76.7 million for integrated product team engineering and technical support to terrestrial and human intelligence programs (North Charleston, completion August 2031) and another at $25.6 million for classified projects at Naval Information Warfare Center Atlantic (North Charleston, completion August 2031). An earlier September 2023 order for Distributed Common Ground Surface System engineering and technical support totaled $58.2 million (Cainhoy, completion April 2028), with FY2024 invoicing of $5.9 million across 31 FTEs and 64,563 contractor hours at a blended rate of $91.66 per hour, utilizing subcontractors including Science Applications International Corporation and Vickers & Nolan Enterprises LLC. A June 2026 Marine Corps delivery order for intelligence engineering sustainment and cyber support carries a $30.2 million ceiling (Hanahan, completion December 2031).
