Marine Systems Corporation

Marine Systems Corporation, a Boston-based maritime and naval engineering firm, operates as a prime contractor on over 1,100 federal awards (99% of recent activity) with a small business designation spanning Total Small Business set-asides and full-and-open competition, serving the Department of the Navy with specialized shipboard engineering, design, and technical support across multiple contract vehicles.

Marine Systems Corporation holds more than 45 years of federal contracting experience as a for-profit entity headquartered in Boston, Massachusetts. The company competes under Total Small Business set-aside designations on a significant portion of its work, particularly under Naval Sea Systems Command purchase orders and delivery orders, while also winning full-and-open competition awards on larger engineering task orders, notably under Seaport-NXG and GSA vehicles. The vendor's capability footprint centers on naval architecture, ship design, habitability engineering, shipboard system integration, barge engineering and overhaul design, technical assessment services, and waterfront engineering support. Representative prime work includes a $21.4 million Seaport-NXG delivery order for Air Cushion Vehicle crew and operations support through February 2027 (Panama City, Florida, with SCI-reported labor growth from $1.2 million and 8.9 FTEs in FY2022 to $3.8 million and 18.0 FTEs in FY2024); a $4.43 million cost-plus-fixed-fee habitability support extension to Naval Sea Systems Command through January 2027 (Norfolk, Virginia); and a $9.24 million Seaport-NXG delivery order from NAVSEA for ship checks and report writing supporting barge life extension at Puget Sound Naval Shipyard through September 2026 (Bremerton, Washington).

Customer concentration is overwhelming and Navy-centric. Naval Sea Systems Command anchors 445 awards (combined potential value $10.42 billion), representing 91% of the portfolio's award count and essentially all of the vendor's dollar exposure. Military Sealift Command contributes 30 awards ($92.2 million), Naval Supply Systems Command 25 awards ($13.3 million), and the Maritime Administration 32 awards ($1.9 million); these four Navy-aligned customers account for 91% of all awards. Defense Contract Management Agency, which issues habitability delivery orders, carries four awards totaling $14.2 million. The concentration signal is categorical: Marine Systems Corporation is a Navy engineering services vendor with minimal diversification across other federal agencies.

The vendor's primary parent vehicles are multiple Navy IDIQ contracts. The top vehicle, Indefinite Delivery Contract N0014001DN642, carries 202 task orders; Indefinite Delivery Contract N0040606D6027 holds 149 task orders ($8.8 million combined potential value); Marine Design and Engineering Services 2015–2020 anchors 50 task orders ($11.6 million); Basic Ordering Agreement N0014086D9595 contains 42 task orders; and Indefinite Delivery Contract N0014088DRJ41 lists 35 task orders. Additionally, Marine Systems Corporation holds its own small business multiple award IDIQs: an OASIS+ Total Small Business set-aside awarded by GSA Federal Acquisition Service in December 2024 (ceiling $999,999,999,999, performance through December 2029) for integrated professional services across management, technical, engineering, R&D, intelligence, environmental, and logistics domains; and an Electrical Services MAC IDIQ awarded by Military Sealift Command in June 2025 (ceiling $44.6 million, performance through June 2030) for turn-key repairs and maintenance of shipboard electrical systems on MSC vessels. These vehicles position Marine Systems Corporation as both an order-placer on Navy engineering vehicles and a holder of downstream small business set-aside vehicles.

Activity has remained modest and flat across the past five years—13 awards in 2022, declining to 7 in 2023, rising to 9 in 2024, 12 in 2025, and 2 so far in 2026—though combined potential value across all awards reaches $10.57 billion, indicating that recent awards are relatively small relative to the historical ceiling values on the Navy vehicles. Six awards face ultimate completion within the next twenty-four months with combined potential value of $166.1 million, representing meaningful recompete exposure but concentrated in what appear to be smaller task orders. SCI-reported invoiced revenue on federal service contracts shows growth: $8.2 million (59.4 FTEs) in FY2022, declining to $6.4 million (53.9 FTEs) in FY2023, then expanding to $11.9 million (71.2 FTEs) in FY2024. Government-paid median hourly rates on prime SCI contracts run $68.77/hr, with rates ranging from $54.97/hr (10th percentile) to $86.33/hr (90th percentile), positioning Marine Systems Corporation in the mid-range of federal engineering labor. Across SCI-reportable prime contracts, the vendor subcontracts approximately 31% of total contractor hours to an average of 18 named subcontractors, indicating material reliance on sub-teaming; named recent subs include Huntington Ingalls (MSC support and LPD contracts), HII Fleet Support Group (technical work documents at Puget Sound Naval Shipyard), SAIC (Air Cushion Vehicle hull and electrical systems engineering), CACI Federal (PEO USC professional support services), and Reliability & Performance Technologies (PMS 377 waterfront support).

Marine Systems Corporation competes almost exclusively as a prime (99% of awards), with only 12 sub awards on record—a profile consistent with a Navy-centric engineering firm that wins vehicle positions and then manages its own supply chain rather than feeding work to larger primes. The vendor's market position rests on sustained presence across established Navy engineering vehicles, small business set-aside eligibility, and specialized maritime technical expertise, with minimal customer diversification and relatively flat recent award velocity offsetting a substantial cumulative backlog of multi-billion-dollar ceiling values on Navy IDIQs.
