About JMS Naval Architects LLC
JMS Naval Architects LLC, a veteran-owned small business based in Mystic, Connecticut, delivers naval architectural design, marine engineering analysis, and ship inspection and maintenance services to federal civilian agencies as a prime contractor, competing full-and-open with no set-aside designation across its recent award footprint.
JMS operates entirely as a prime contractor (100% of awards) across marine and coastal research missions. The vendor's customer base concentrates heavily with the Department of the Interior's U.S. Geological Survey Office of Acquisitions and Grants, which accounts for 20 awards (82% of awards by count, $6.1 million combined potential value) under a $2 million single-award indefinite delivery contract extending through October 2027. The Department of Commerce's National Oceanic and Atmospheric Administration represents the second major customer with 7 awards ($5.2 million combined potential value), followed by the National Science Foundation, which placed a $4.3 million delivery order on August 16, 2026, for ship inspection and maintenance services under the GSA Multiple Award Schedule. These three customers account for 93% of JMS's combined potential value across the portfolio. Within the USGS relationship, JMS performs naval architecture, engineering analysis, noise reduction studies, directional stability assessments, and shipyard packaging in support of coastal and marine science programs, with delivery orders ranging from approximately $6,000 to $220,000 over the contract life.
JMS holds positions on the GSA Multiple Award Schedule (17 task orders, $14.3 million combined potential value) and operates under a USGS single-award indefinite delivery contract valued at up to $2 million. The vendor's GSA Schedule labor portfolio spans seven categories, ranging from $98.72 per hour for a Designer role (High School Equivalent, five years experience) to $189.55 per hour for a Principal Engineer (bachelor's degree, fifteen years experience), with intermediate naval architect, marine engineer, and project manager positions covering the mid-range. No security-cleared labor is offered. Work is performed primarily in Connecticut (Mystic and Stonington) and Michigan (Ann Arbor), with recent awards representing coastal research, maritime infrastructure assessment, and oceanographic support for federal science agencies.
Activity has declined over the past five years, from two awards in 2022 to one award annually in 2023–2026, with only two awards reaching ultimate completion within the next twenty-four months (combined potential value $1.5 million). Combined obligated dollars across all 38 awards total $6.5 million against combined potential value of $23.4 million (28% obligation rate). The vendor's award portfolio reflects specialized expertise in marine engineering and naval architecture; NAICS coding shows 37 awards under Engineering Services, with PSC coding dominated by Architect and Engineering—General: Marine Engineering (20 awards) and ship inspection and repair categories.
