ACUA Ocean’s new uncrewed surface vessels (USVs) will be named the Pioneer-class, and will feature a hybrid-electric propulsion system.
The Pioneer-class USVs will also be built ready to receive either a gaseous hydrogen or a low-emission diesel powertrain dependent on end-user specifications or mission parameters.
The prototype first of its class vessel “USV PIONEER” is currently in build at Aluminium Marine Consultants (AMC) on the Isle of Wight. Future vessels in the class will be named after leading pioneers in the fields of exploration, science and technology.
The 14 meter Pioneer-class vessel has recently been granted a UK patent for the inventiveness of the modular small water-plane twin hull (SWATH) design which enables both modularity of build and also the deployment of modular sensor and system payloads.
Research conducted by the University of Southampton, including wave tank testing and digital simulations, show the Pioneer-class USVs outperforming the seakeeping stability of a monohull vessel 3x its length and 10x its displacement.


USV Pioneer’s exceptional platform stability, payload versatility, portability and scalability meet the increasing need of end users for high-quality data and operational availability and reliability in open ocean conditions but delivered at a fraction of the cost of larger crewed or autonomous platforms.
In addition to the Pioneer, ACUA is developing a 24m long-endurance high-powered USV called Maelstrom. The Maelstrom will deliver enhanced and scalable capabilities for a range of commercial and defence customers.
USV Pioneer is scheduled to commence sea trials in Q4 2024, whilst the Maelstrom is scheduled to enter service in 2026.
