ST Engineering’s Multi-Role Vessel (MRV) made its European debut at Euronaval 2026 as a scale model of a crewed mothership intended to deploy and coordinate unmanned systems. The proposed ship is 150 metres long, has a stated displacement of 8,000 tonnes and would remain the command-and-control platform while unmanned surface vessels conduct surveillance, reconnaissance and threat-investigation missions at sea, according to EDR Magazine’s report from the show.
The practical answer for operators is that the MRV is presented as a human-led force architecture, not as an autonomous ship operating without supervision. EDR reports that the manned vessel would retain command authority while coordinating multiple autonomous or remotely operated assets. That establishes the intended division of labour: the unmanned vessels would perform offboard tasks, while sailors aboard the MRV would direct the wider mission and make decisions. The report does not establish how individual vehicles would navigate, communicate, hand off tasks or receive operator intervention.
The MRV’s own proposed equipment also separates ship capability from unmanned-system evidence. EDR describes electro-optical systems, fire-control radar, a fixed-panel electronically steered multifunction radar and cybersecurity capabilities, along with proposed MICA and Aster surface-to-air missiles, a surface-to-surface missile system, a 76 mm Strales gun and a 30 mm remotely controlled weapon system. Those details describe the mothership’s planned combat architecture; they do not show that its unmanned vessels have demonstrated those functions. The source reports a scale-model presentation rather than a sea trial or operational deployment of the MRV.
A separate Euronaval report provides useful context for the control model without validating ST Engineering’s ship. Naval News reports that Babcock’s ARMOR Force framework combines crewed, lean-crewed and uncrewed systems under commanded autonomy, with human oversight and decision-making authority. Babcock also describes integration, simulation and testing as part of its delivery approach. That is a stated framework and support model, not performance evidence for the MRV. Taken together, the documents support a concrete distinction: the MRV’s proposed mission and human-control arrangement are documented, while its autonomy boundaries, control performance and operational readiness remain unverified.
