Autonomous Systems: Land & SeaBackground
Type 91 is a planned Royal Navy class of uncrewed missile-carrying vessel, roughly 70 to 75 metres long, whose role and size were confirmed in July 2026 alongside three sibling autonomous classes, Type 92, Type 93 and Type 94.
The Ministry of Defence has committed at least GBP 1.5 billion over four years across the four classes, with a prototype missile platform targeted for service by 2030 as part of a wider surface fleet redesign in which crewed mothership vessels direct uncrewed shooters and sensors.
No contractor has yet been named for Type 91, and delivery risk beyond the 2030 aspiration remains unquantified, making the class one of the clearest tests of whether the Royal Navy's autonomy ambitions convert into hulls on schedule.
