OPT reports WAM-V maritime trials at REPMUS 2026

Three WAM-V classes supported maritime experimentation and US operator training, according to their manufacturer.

Ocean Power Technologies reported on 21 September that its WAM-V 8, 16 and 22 surface vessels participated in REPMUS 2026 in Portugal. The company described activity spanning environmental assessment, mine countermeasures, harbour security, surveillance and above-water warfare.

OPT also reported integration with US command-and-control systems and training for US Navy and Marine Corps personnel.

Why it matters

Testing several vessel sizes within an allied exercise provides evidence of integration work beyond a standalone demonstration. These are manufacturer-reported exercise results. The announcement does not establish a new procurement award or fleet-wide operational acceptance.
