About the company
Thayermahan, Inc., based in Groton, Connecticut, develops autonomous mobile maritime systems, tactical surveillance platforms, and undersea warfare technologies for the Department of the Navy, the Coast Guard, and related defense agencies, operating predominantly as a prime contractor (83% of recent awards) across research and development, systems development, and vessel services without set-aside designations.
Thayermahan holds a portfolio anchored in defense maritime capabilities. The Department of Homeland Security US Coast Guard dominates customer concentration by potential value — two awards totaling $99 million, driven by an April 2026 multiple-award IDIQ (ceiling $99 million, five-year term through March 31, 2031) for command, control, and logistics support services including time-charter vessel services capable of operating across the Caribbean Basin, Gulf of America, Pacific Area, and Polar Regions. The Department of the Navy Secretary of the Navy Office of Naval Research accounts for $38.8 million in combined potential value across two awards, including a $19.3 million cost-plus-fixed-fee contract (awarded October 2023, completion October 2027) for development of autonomous mobile maritime systems for tactical surveillance, undersea warfare, and subsea and seabed warfare. The Office of the Secretary of Defense contributed a $2.1 million Other Transaction Agreement (awarded August 2022, completed November 2023) for autonomous perimeter security development. Thayermahan's R&D footprint spans multiple Navy commands: Naval Sea Systems Command placed two SBIR awards ($1.9 million combined potential value), and Naval Strategic Systems Programs awarded a $239,829 SBIR Phase I contract (November 2025, completion May 2026). The National Oceanic and Atmospheric Administration funded a $1.1 million SBIR Phase III contract (awarded March 2023, completion November 2025). Across the portfolio, research and development in physical, engineering, and life sciences dominates the NAICS category (seven awards), with Deep Sea Freight Transportation representing two awards and reflecting the Coast Guard vessel charter work.
Activity has been episodic over the source period — one award in 2022, three in 2023, one in 2024, two in 2025, and two in 2026 (most recent April 2026). Combined potential value stands at $143.1 million with $25.6 million obligated to date (18% of potential). Two awards carrying $19.3 million in combined potential value reach completion within the next twenty-four months, creating recompete exposure. Thayermahan subcontracts under Parsons Government Services Inc. on Bold Venture Services work (awarded June 2025) and under Raytheon on research and development (awarded November 2024). The company holds a named subsidiary, Ocean Acoustical Services And Instrumentation Systems, Inc., signaling acoustics and instrumentation depth in maritime applications.
