Ocean Power Technologies Inc (NYSE-A:OPTT) said 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.
The annual exercise, run with NATO, the University of Porto, and the European Defense Agency, brings together military forces, academia, and technology companies to test and integrate unmanned systems into real-world maritime operations, with a focus on interoperability among allied unmanned systems.
OPT vessels supported five mission sets during the exercise: 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 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 used 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, COO 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.”
