Ocean Power Technologies Operates Three WAM-V Classes Across Five Mission Sets at REPMUS 2026

OPT’s WAM-V unmanned vessels saw operational use and U.S. forces training roles during the NATO-linked REPMUS 2026 exercise in Portugal.

Rhea-AI Summary

Ocean Power Technologies (OPTT) deployed three classes of its WAM-V unmanned surface vessels across five mission sets during the REPMUS 2026 multinational robotic experimentation exercise in Portugal.

The WAM-V 8 performed rapid environmental assessment and bathymetric surveys in amphibious surf zones, while the WAM-V 16 supported mine countermeasures and harbor security in beach and harbor approaches. The WAM-V 22 executed above‑water warfare tasks, including surface target identification and intelligence, surveillance and reconnaissance. OPT vessels integrated with U.S. command and control and were the only U.S. unmanned surface vessels to do so, with a WAM-V 22 also used to train U.S. Navy and Marine Corps personnel in basic autonomous operations.

unmanned surface vessels technical

"three classes of its WAM-V® unmanned surface vessels operated across multiple mission sets"

Autonomous or remotely controlled boats that operate on the water’s surface without an onboard crew, like self-driving cars for rivers, lakes and oceans. Investors watch them because they can cut labor and fuel costs, enable new services (surveying, shipping, surveillance) and win government or commercial contracts, but their value also depends on regulatory approval, reliability and cybersecurity—factors that affect revenue and risk.

mine countermeasures technical

"The WAM-V 16 supported mine countermeasures tasking"

Mine countermeasures are the tools and activities used to find, disable, remove or avoid explosive mines in water and on the seabed, protecting ships, ports and offshore operations. Think of it like a specialized cleanup crew that detects hidden hazards and clears safe passages; for investors, demand for these services and technologies affects defense contractors, marine-service providers and companies involved in shipping and port security, especially in regions with heightened naval risk.

bathymetric survey data technical

"delivering bathymetric survey data in amphibious surf zones"

Measurements and maps of the shape, depth and features of the seabed or riverbed collected with tools like sonar, multibeam echo sounders, lidar and GPS. Like a topographic map for underwater ground, this data matters to investors because it informs project planning, safety, permitting, dredging, navigation and asset placement for marine and shoreline activities, helping estimate costs, engineering needs and regulatory compliance risks.

intelligence, surveillance and reconnaissance technical

"conducted intelligence, surveillance and reconnaissance"

Intelligence, surveillance and reconnaissance (ISR) are the activities and systems used to gather information about people, places and events—like a combination of watching with cameras and sensors, collecting clues, and making sense of them to know what is happening or likely to happen. Investors care because ISR drives demand for specialized equipment, software and services and affects national security spending and risk assessments; companies involved can see steady contracts, technology-driven growth, or heightened scrutiny depending on geopolitical developments.

WAM-V unmanned surface vessels integrated with U.S. command and control and supported training for the U.S. Navy and Marine Corps personnel in autonomous operations during the multinational exercise in Portugal

MONROE TOWNSHIP, N.J., Sept. 21, 2026 (GLOBE NEWSWIRE) -- Ocean Power Technologies, Inc. (“OPT” or the “Company”) (NYSE American: OPTT), a leader in maritime operational infrastructure and autonomous ocean systems, today announced that three classes of its WAM-V^® unmanned surface vessels operated across multiple mission sets at REPMUS 2026, the multinational robotic experimentation exercise led by the Portuguese Navy in close collaboration with NATO, the University of Porto, and the European Defense Agency (EDA).

The annual exercise brings together military forces, academia, and technology companies from across the globe to test, develop, and integrate unmanned systems into real-world maritime operations. The exercise is designed to drive multi-domain interoperability among allied maritime unmanned systems under realistic operational conditions.

Over the course of the exercise, OPT vessels supported five mission sets: rapid environmental assessment; mine countermeasures; harbor security; surveillance and reconnaissance; and above-water warfare.

The WAM-V 8 conducted rapid environmental assessment, delivering bathymetric survey data in amphibious surf zones in support of landing and raiding forces, and was beach-launched ahead of amphibious operations. The WAM-V 16 supported mine countermeasures tasking in the beach and harbor approaches for harbor security. The `WAM-V 22 operated in above-water warfare, including surface target identification under operational tasking, and conducted intelligence, surveillance and reconnaissance.

OPT vessels integrated with U.S. command and control during the exercise and were the only U.S. unmanned surface vessels to do so. A WAM-V 22 was also employed to train U.S. Navy and Marine Corps personnel in basic autonomous operations.

“The test of an unmanned system isn’t whether it performs at a demonstration. It’s whether an operational commander will task it alongside everything else he’s responsible for,” said Jason Weed, Chief Operating Officer of OPT. “At REPMUS, our vessels weren’t on display; they were given work. Three different classes, five different missions, inside someone else’s operational picture. That’s the capability our customers are actually buying.”
