Type 91
A planned Royal Navy class of uncrewed surface missile platform named in the 2026 Defence Investment Plan.
Type 91, the Royal Navy's planned 70 to 75-metre uncrewed missile vessel, had its size and role confirmed on 16 July 2026, targeting a 2030 prototype, but the Ministry of Defence has yet to name a shipyard or contractor.

Type 91 is a planned Royal Navy class of uncrewed missile-carrying vessel, roughly 70 to 75 metres long, one of four autonomous classes named alongside Type 92, Type 93 and Type 94. It sits within a GBP1.5bn, four-year Ministry of Defence funding line covering all four classes, part of a wider surface fleet redesign in which crewed motherships direct uncrewed shooters and sensors rather than fighting alone.
No contractor has yet been named for Type 91, and delivery risk beyond the 2030 prototype aspiration remains unquantified, making the class one of the clearest tests of whether the Royal Navy's autonomy ambitions convert into hulls on schedule.
