ACUA Ocean's Mk1 USV PIONEER has successfully completed a five-day remotely operated offshore demonstration, validating the concept of persistent, multi-domain maritime operations using a long-endurance uncrewed surface vessel.

On Monday June 22, 2026, PIONEER departed Turnchapel Wharf and operated continuously for more than 100 hours at sea without physical intervention. The demonstration combined two independent mission systems operating simultaneously:

A CommsAudit SPECTRA Super Resolution Direction Finding (SRDF) surveillance system, with antenna and receivers installed aboard PIONEER.
An advanced Multi-Beam Echo Sounder (MBES) undertaking hydrographic survey operations. Both these systems were integrated, tested and commissioned within just two days—a testament to the utility and versatility of the PIONEER platform.

To demonstrate seamless Land/Sea operations, the RF surveillance capability was supplemented by a second land-based Electronic Warfare system, Guardian Vantage, provided by Leonardo and deployed on England’s south coast.
