About this award

The Marine Corps issued a $25.6 million delivery order to Fathom 4 LLC, a service-disabled veteran-owned small business, on February 17, 2026, under Seaport Next Generation (Seaport-NXG) for sensing and information operations classified projects at Naval Information Warfare Center Atlantic.

Seaport-NXG is a Navy-administered indefinite delivery vehicle for C4ISR engineering, integration, and technical sustainment services to the Department of Defense. Place of performance is North Charleston, SC. The order runs through August 16, 2031, on a cost-plus-fixed-fee basis with incremental funding. Fathom 4 operates as a prime on Seaport-NXG task orders and subcontracts to major defense integrators; the company's recent portfolio is weighted toward Navy and Marine Corps programs, with current recompete exposure on two awards carrying combined potential value of $72.6 million due within the next twenty-four months.
