About Mccullough Engineering Services Inc.
Mccullough Engineering Services Inc., a self-certified small disadvantaged business based in Moss Point, Mississippi, provides technical engineering services for naval and maritime applications as a prime contractor (75% of recent awards) and occasionally as a subcontractor to larger defense primes. The firm operates as a Subchapter S corporation and specializes in ship system repair, power systems integration, and technical commissioning support for the Department of the Navy and Department of the Army.
Mccullough's customer concentration is entirely within the defense maritime sector. All four recent awards split between the Department of the Navy Naval Sea Systems Command (three awards, $392 thousand combined potential value) and the Department of the Army (one award, $100 thousand). The Navy work centers on mission-critical power and backup systems: a $377.5 thousand firm fixed-price purchase order for technical data and a mission clean power and backup system completed in April 2024, and a $14 thousand purchase order for uninterruptible power supply start-up commissioning and familiarization training on the T-AGS 67, with completion scheduled for December 1, 2026. The Army contract was a $99.9 thousand definitive contract for TLI system repair on the McFarland. All three prime awards carried total small business set-aside designations.
Award activity is sparse and episodic — one award in 2022, one in 2024, and two in 2026 — with a combined potential value of $491 thousand across the portfolio. One award (the T-AGS 67 commissioning contract) reaches ultimate completion inside the next twenty-four months and therefore faces recompete exposure. Mccullough subcontracts to BAE Systems Maritime Solutions Norfolk Inc. on a February 2024 sub-award tied to LPD 29 Full Operations Assessment work. Service Contract Inventory data shows minimal SCI footprint: 0.2 FTEs in FY2022 under a single subcontractor record, indicating that Mccullough's federal work is dominated by small-value product and equipment contracts rather than labor-intensive service delivery. The firm's capability portfolio, grounded in recent awards, targets ship-systems engineering, uninterruptible power supply commissioning, and tactical systems repair on Navy vessels and Army watercraft.
