Hydronalix Inc.

Hydronalix Inc., a small business manufacturer of advanced unmanned systems and maritime robotics headquartered in Green Valley, Arizona, operates as a prime contractor (98% of recent awards) on naval research and development work with the Department of the Navy and allied defense agencies, competing predominantly under total small business set-asides and full-and-open designations without reservation for a specific SBA certification category.

Hydronalix's capability portfolio centers on autonomous navigation systems, unmanned surface vehicles (USVs), Mobile Gateway Buoy (MGB) platforms, robotic rescue systems, and mine countermeasures technology. Representative work includes a $10.6 million SBIR Phase III research and development delivery order from the Naval Air Warfare Center (awarded September 2022, completion September 2026) for advanced unmanned systems development; a $10.9 million delivery order from the Naval Information Warfare Systems Command for Mobile Gateway Buoy production, engineering support, and field service (awarded November 2024, completion November 2027); a $7.5 million cost-plus-fixed-fee research contract from the Office of Naval Research (awarded November 2023, completion September 2026); and a $3.0 million firm fixed-price purchase order from the Marine Corps for USV1 HULL 1 development and integration (awarded December 2023, completion March 2025). More recent work includes a $425 thousand delivery order from the Washington Headquarters Service for MGB sustainment and mine countermeasures R&D (awarded July 2026, completion July 2028). Hydronalix also received a $250 thousand STTR Phase I contract from TACOM Life Cycle Management Command in collaboration with the University of Texas at Arlington Research Institute to develop a Swarm Capable Autonomous Robotic Aquatic Bridging System (awarded September 2025, completion March 2026). Non-defense exposure includes a modular drone humanitarian attachment project (HERMES system) funded through a Federal Emergency Management Administration grant from the Institute of Youth, Family, and Community (awarded July 2023) targeting disaster response in rural areas.

Customer concentration is heavily weighted toward naval warfare and research centers. The top five customer agencies account for 93% of combined potential value: the Department of the Navy Information Warfare Systems Command (3 awards, $42 million), the Naval Air Systems Command Naval Air Warfare Center (16 awards, $36.7 million), the Washington Headquarters Service (2 awards, $11.3 million), the Office of Naval Research (5 awards, $9.9 million), and the Department of the Air Force (1 award, $3.2 million). By award count alone, Naval Air Warfare Center dominates with 16 awards; however, Naval Information Warfare Systems Command anchors the dollars through a single $42 million indefinite delivery contract running through October 2029. Other customer agencies include the National Oceanic and Atmospheric Administration, the Defense Advanced Research Projects Agency, the Department of the Interior National Park Service, the Defense Threat Reduction Agency, and US Special Operations Command.

Hydronalix holds two named parent vehicles: a Basic Ordering Agreement N6833514G0039 under which 4 task orders carry $13.8 million in combined potential value, and an Indefinite Delivery Contract N6600125D0008 (the Naval Information Warfare Systems Command award running through October 2029) under which 3 task orders carry $11.3 million. A third vehicle, Basic Ordering Agreement N6833522G0002 from Naval Air Warfare Center, supports 1 task order valued at $10.6 million. The company also holds a single-award Basic Ordering Agreement with Naval Air Warfare Center established January 2022 for SBIR Phase III work, with no specified ceiling.

Activity has contracted year over year after 2023, declining from 8 awards in both 2022 and 2023 to 4 in 2024, 1 in 2025, and 1 in 2026 to date. This reflects the lumpy nature of SBIR/STTR program funding and larger delivery orders that consolidate volume into fewer transactions. Recompete exposure in the next twenty-four months is moderate: 2 awards with ultimate completion dates in that window carry $11.3 million in combined potential value. Hydronalix subcontracts minimally — one identified sub-award under Southwest Research Institute on a Special Operations Command project (December 2023). The company's work is classified across R&D NAICS categories (Research and Development in Physical, Engineering, and Life Sciences: 28 awards) and boat building (8 awards), with corresponding PSC clustering in National Defense R&D Services and Small Craft procurement codes.
