Background
RFA Lyme Bay is a Royal Fleet Auxiliary landing ship dock that is serving as the mothership for the Royal Navy's autonomous mine-countermeasures force package. On 27 May 2026 the crewless minehunter RNMB Ariadne docked inside Lyme Bay off Gibraltar on its first attempt, marking the first successful at-sea recovery of an autonomous minehunter into a mothership in Royal Navy history. Lyme Bay had sailed from Gibraltar two days earlier toward a potential mine-clearance mission in the Strait of Hormuz.
The ship carries both RNMB Ariadne and the Project Beehive Kraken K3 Scout USVs, making it the platform from which the Royal Navy's first operational autonomous mine-countermeasures force would be commanded and controlled. The use of a large support ship as an autonomous vessel carrier rather than a combat vessel reflects the Royal Navy's concept of crewed platforms as motherships for uncrewed systems, with the crew ashore or aboard the mother vessel rather than above the minefield.
Lyme Bay's Hormuz deployment is the operational realisation of the First Sea Lord's 19 May 2026 doctrine. The mission is described as strictly defensive; clearance operations had not begun as of the departure.
