Greensea Systems, Inc.

Greensea Systems, Inc., doing business as Greensea IQ, manufactures custom software and hardware for unmanned and autonomous maritime systems, competing as a prime contractor (86% of recent awards) on full-and-open Navy and Marine Corps production and sustainment contracts without set-aside designation. The Richmond, Vermont–based small business holds two single-award indefinite-delivery contracts worth a combined $31.2 million ceiling and has delivered amphibious unmanned ground vehicles, underwater controllers, remotely operated vehicle simulation systems, and autonomous maritime platforms to Navy and Marine Corps customers since 2022.

Greensea's customer concentration is almost entirely Navy and Marine Corps. The top five Navy and Marine components account for 72% of recent awards by count and 99% of combined potential value. The Marine Corps leads by dollars ($29.5 million across 4 awards), followed closely by Naval Information Warfare Systems Command ($25.9 million across 5 awards) and Naval Sea Systems Command ($12 million across 7 awards). The gap between award count and potential value reflects Greensea's heavy reliance on two large IDIQs: a $13 million single-award Marine Corps vehicle for Amphibious Unmanned Ground Vehicle procurement (awarded August 2025, through August 2030) and an $18.2 million single-award Naval Information Warfare Systems Command vehicle for Greensea Controller Integration and Sustainment (awarded June 2026, through June 2033). Against the latter, Greensea has booked a $5.8 million delivery order for bayonet underwater controllers and kits (July 2026). Representative prime work includes a $9 million firm-fixed-price Marine Corps delivery order for AUGV production units (August 2025, completion August 2030), a $3.7 million Marine Corps Other Transaction Agreement for Autonomous Amphibious Response Vehicle prototyping (awarded May 2022, completed May 2024), and four Naval Sea Systems Command SBIR Phase I and Phase II awards totaling roughly $6.3 million for Space-Based Infrared System High research and development (2024–2025).

Activity has accelerated in the past two years — one award in 2023 to seven in 2025 — though 2026 year-to-date shows four awards. Six awards with combined potential value of $11.9 million face ultimate completion within the next twenty-four months and therefore carry recompete risk. Greensea operates as a subcontractor to Leidos on Naval Information Warfare Center Pacific autonomous systems design and engineering (awarded August 2025) and holds grant sub-awards with Woods Hole Oceanographic Institution on a National Science Foundation deep submergence facility remotely operated vehicle project (January 2025) and with the National Center for Manufacturing Sciences on automated marine corrosion inspection systems (March 2024). Greensea's capability stack spans submersible controllers, amphibious unmanned vehicles, explosive ordnance disposal platforms, forward-looking sonar integration, and simulation systems for remotely operated vehicle training, with all recent prime activity routed through Navy and Marine Corps contracting offices and no DoD agency diversification visible in the award record.

Greensea Systems, Inc., makes marine vehicles smart by providing integrated inertial navigation systems, autopilots, mission planning, and automation based on their patent-pending technology, openSEA. Greensea's technology is robust, precise and operator friendly, making it the system of choice for some of the biggest names in the business, such as MBARI, ROPOS, NOAA, MOOG, Vulcan, NPS, US Army Corps of Engineers, NavSea, Oceaneering, Tritech, Kongsberg, Teledyne SeaBotix and many more. For nearly a decade, Greensea has been devoted to developing technology that helps man and machine work together. Greensea now offers commercially available products as well as custom engineering solutions that utilize the powerful openSEA core technology to provide robust, turnkey solutions that are offshore ready.
