Marine Systems Corporation

Marine Systems Corporation, a for-profit Boston-based maritime engineering and naval architecture firm with over 45 years of federal contracting experience, operates as a prime contractor on Navy ship design, habitability, and engineering services—accumulating 1,125 prime awards (99% of its footprint) across a $10.57 billion combined potential value pipeline. The vendor competes predominantly under Total Small Business set-asides on Navy-administered IDIQs and holds positions on the GSA OASIS+ Small Business GWAC and the Military Sealift Command Electrical Services MAC IDIQ.

Navy Sea Systems Command dominates Marine Systems Corporation's customer concentration, accounting for 446 awards carrying $10.42 billion in combined potential value—a concentration that dwarfs secondary customers. Military Sealift Command (31 awards, $92.2 million), the Defense Contract Management Agency (4 awards, $14.2 million), and the Maritime Administration (33 awards, $2 million) round out the top five. The top-customer rankings align closely: Naval Sea Systems Command is both the largest customer by volume and by dollars, anchoring the vendor's entire federal footprint. Across the portfolio, 91% of awards concentrate with Navy organizations, signaling heavy institutional lock-in.

Marine Systems Corporation's capability portfolio centers on naval architecture, ship habitability engineering, barge and vessel design, engineering and technical assessment, and shipboard system integration. Representative prime work includes a $21.4 million Seaport-NXG delivery order (issued February 2022, running through February 2027) for Air Cushion Vehicle crew, safe engineering and operations, and future Seabase connectors program support in Panama City, Florida; a $9 million Seaport-NXG delivery order (September 2024) for barge life-extension ship checks and report writing at Puget Sound Naval Shipyard; a $4.4 million Naval Sea Systems Command habitability delivery order (January 2026, completing January 2027) with cost-plus-fixed-fee structure; and a $44.6 million Military Sealift Command Electrical Services IDIQ (awarded June 2025, running through June 2030) for turn-key repairs and maintenance of shipboard electrical systems across MSC vessels. The vendor also holds a position on the GSA OASIS+ Small Business GWAC (awarded December 2024, no dollar ceiling specified in the source, running through December 2029) with a minimum guarantee of $2,500, enabling task-order competition across seven functional domains—Management and Advisory, Technical and Engineering, Research and Engineering, Intelligence Services, Environmental Services, Facilities, and Logistics.

On vehicle positioning, Marine Systems Corporation sits on two foundational IDIQs. The largest undesignated Navy IDIQ (N0014001DN642) carries 202 task orders; a second large IDIQ (N0040606D6027) carries 149 task orders valued at $8.8 million combined potential value. The Marine Design and Engineering Services 2015–2020 vehicle anchored 50 task orders at $11.6 million; a Basic Ordering Agreement (N0014086D9595) carried 42 task orders. Across these vehicles, Marine Systems Corporation's work centers on ship design, engineering assessment, habitability support, and technical documentation—core naval architecture and marine engineering services.

Activity trajectory shows volatility: the vendor averaged 9 awards annually over the past five fiscal years (2022–2026), with 2022 and 2025 representing the strongest years (13 and 12 awards respectively) and 2023 and 2026 showing decline (7 and 4 awards, respectively). Within the next 24 months, five awards totaling $152.6 million in combined potential value reach ultimate completion, presenting recompete exposure—most significantly, the large Seaport-NXG and habitability delivery orders currently dominating backlog face extension or recompete decisions in that window.

Across SCI-reportable federal service contracts, Marine Systems Corporation invoiced $34.4 million on prime contracts from FY2022 through FY2025, with peak invoicing of $11.9 million in FY2024 supporting 71.2 FTEs (contract-level aggregation). The FY2025 data shows $7.9 million invoiced across 59.2 FTEs. Government-paid hourly rates on federal services contracts run a median of $69.19/hr, with the 10th percentile at $54.69/hr and the 90th percentile at $82.37/hr, reflecting a mix of junior and senior technical labor. Across SCI-reportable prime contracts, Marine Systems Corporation subcontracts an average of 32% of contractor hours to a roster of 24 named subcontractors, including Huntington Ingalls Incorporated, HII Fleet Support Group LLC, SAIC, CACI Federal, Reliability & Performance Technologies, and Sayres and Associates LLC—signaling a balanced build-versus-buy delivery posture on habitability and ship-system work.

The vendor's sub-award activity (12 sub awards, 1% of total awards) concentrates under Huntington Ingalls (six sub awards spanning MSC support, LPD production, and provisioned items), HII Fleet Support Group (two sub awards for technical work document preparation and shipcheck support at Puget Sound Naval Shipyard), SAIC (two sub awards for Air Cushion Vehicle prototype development and engineering), CACI Federal (one sub award for PEO USC professional support and program management), Reliability & Performance Technologies (waterfront support services), and Sayres and Associates (program management and integrated support for PMS 300/325 programs). This teaming profile positions Marine Systems Corporation as a capable subcontractor feeder to large ship-construction and ship-maintenance primes, while maintaining a dominant prime posture across Navy engineering vehicles.

Marine Systems Corporation's engineering services category (497 awards) and support–professional engineering/technical category (284 awards) dominate its NAICS and PSC footprint, with Marine Engineering (PSC code) claiming 417 awards. The vendor's set-aside posture remains consistent: Total Small Business designations recur across the majority of Navy awards, underpinning its competitive positioning on reserved vehicles and sole-source opportunities within Navy small-business set-asides. This posture anchors the vendor to a specific customer and vehicle ecosystem with limited exposure to full-and-open competition or non-Navy federal markets.
