4000 Subscribers Thankyou Special – The Royal Navy if I were Prime Minister

The fleet exercise is uncosted, yet it confines itself to coherent capabilities based on existing or projected equipment and keeps the rest of defence in view.

The CVA-01 dispute illustrates how attacking another service's programme can make the case for cutting both, weakening national defence and each service's own position.

The proposed fleet is built around two strike carriers and three large amphibious ships, with logistics and escorts treated as the means that make distant power useful.

A Queen Elizabeth-class carrier could normally embark about 400 Royal Marines, with room for roughly 800 in cramped conditions, alongside a mixed air group of F-35B fighters and Merlin helicopters.

Three Canberra-class-sized landing helicopter docks would combine dock, stores, accommodation, hangar, and flight deck capacity while providing limited back-up for a carrier or amphibious ship in refit.

Forward-based landing and logistics ships would handle routine regional tasks, leaving carrier and amphibious task groups available as a larger reaction force.

Six Type 45 destroyers and nine Type 26 frigates would form three high-end escort groups sized around the simultaneous protection of carrier and amphibious forces.

The larger escort and task-group structure would require roughly 25 percent more Royal Navy personnel, making recruiting and crewing part of the capability proposal rather than an invisible assumption.

Nine Type 45 successors would preserve high-end escort availability and allow occasional forward presence, while Type 31 frigates would reinforce battle groups as close escorts in war.

A larger Type 31 force would keep ships in the Falklands, Gibraltar, Bahrain, and Singapore, giving Britain a visible regional stake before a crisis demands a task group.

A modified Batch 3 River class could combine heavier guns, Martlet missiles, StanFlex modules, UAV support, a stern ramp, and optional towed sensors for flexible regional patrol work.

Regional naval stations led by senior captains would coordinate ships, diplomats, partner relationships, disaster relief, and the advance knowledge that makes a fleet more useful in a crisis.

Using amphibious combat vehicles across Royal Marine and strike formations would let troops drive ashore, reinforce one another, and reduce dependence on landing craft for every movement.

A ballistic-missile submarine kept continuously at sea avoids the visible activation and deployment that can make a nuclear force more escalatory during a crisis.

Five compatible Dreadnought-type hulls could support three declared ballistic-missile boats, two conventional cruise-missile SSGNs, and reserve capacity against accidents or refit delays.

Britain's single nuclear-submarine construction yard constrains how quickly SSBNs, Astute-class boats, and a future attack-submarine class can be built, even when a larger fleet is desirable.

A conventional submarine successor could use a Japanese design or a joint sensor-led project, with two boats based in the Falklands for South Atlantic awareness.

Alliances multiply British power, but dependence on American logistics and post-Cold War European cuts mean Britain still needs its own regional forces if it wants influence and warning.

Four regular and two reserve Royal Marine battle groups could form larger amphibious formations, but their scale depends on Point-class strategic lift as well as LHD and dock-landing-ship availability.

Sixteen regular and eight reserve P-8 Poseidons would provide maritime patrol reach from Diego Garcia, the Falklands, and the United Kingdom.

Expanding the Archer-class force to twelve craft would preserve practical training links between universities, reservists, and the wider Royal Navy.

Forward-based mine countermeasures vessels and a retained hydrographic squadron would keep overseas approaches, British ports, and operational waters usable.

Small Royal Marine companies embarked on forward-deployed landing ships would give the fleet a rotating force for independent regional missions while preserving larger commandos for battle groups.
