Autonomous Systems: Land & SeaBackground
The Royal Navy is the United Kingdom's principal maritime warfare service, built around two Queen Elizabeth-class aircraft carriers, six Type 45 air-defence destroyers and eight Type 23/26 frigates, with a standing Gulf presence under Operation KIPION anchored at HMS Jufair, Bahrain, since 1980.
Since early 2026 it has taken on a heavier institutional role as operational lead of the multinational Hormuz maritime Coalition, convening planning at PJHQ Northwood in north-west London under the Macron-Starmer Maritime Freedom of Navigation Initiative. Notably, the United States was excluded from that planning room by design, a structural inversion of the normal transatlantic command relationship, leaving the Royal Navy to draft the rules other navies, including France and Italy, are now committing hardware against.
That Coalition leadership sits alongside a deliberate shift in force structure towards uncrewed systems, positioning the Navy's long-term relevance less on hull numbers than on its ability to command a mixed crewed-and-robotic fleet.
Royal Navy swaps crewed hulls for robots
The Royal Navy is mid-transition from crewed to uncrewed mine-countermeasures. On 30 June the Defence Investment Plan named four new uncrewed classes, Type 91 through Type 94, covering missile, anti-submarine, extra-large underwater and air-sensing roles, the first robot warships formally written into the fleet's structure.
That plan is now visible at sea: on 13 July the Navy retired HMS Chiddingfold, a Hunt-class minehunter in service since 1984, alongside two Type 23 frigates, with mine-hunting duties passing to autonomous underwater vehicles and newer Type 26/31 frigates. The doctrine behind it, set out by the First Sea Lord in May, is "crewed where necessary, uncrewed wherever possible, integrated always".
