The Royal Navy has launched the most extensive fleet overhaul since the Second World War.
First Sea Lord General Sir Gwyn Jenkins announced the modernization drive on 10 November 2026 at the International Sea Power Conference in Norway.
The recapitalization effort combines ongoing construction with longer-term procurement plans. The program includes thirteen frigates. Eight Type 26 anti-submarine frigates are built on the Clyde. Five Type 31 general-purpose frigates are under construction at Rosyth.
Underwater capabilities feature four Dreadnought-class submarines intended to replace Vanguard-class boats carrying the UK nuclear deterrent. The program includes the completion of the Astute attack submarine program. It adds up to twelve next-generation submarines under the AUKUS partnership.
The design incorporates six Common Combat Vessels intended to direct uncrewed maritime systems. Four new amphibious ships support Royal Marines operational reach. Fleet support ships join them.
Construction across existing programs represents about 280,000 tonnes of new steel. That total is projected to rise to about 450,000 tonnes if planned programs proceed.
The renewal program follows a period of decline in available front-line hulls. Official equipment statistics document that four frigates and two landing vessels left the fleet between April 2025 and April 2026.
The Navy counted 52 surface vessels in April 2026. That total encompasses varied vessel types rather than operational combat warships.
Parliament’s Defence Committee warned in an October 2026 report that the service maintained only five towed-array-equipped anti-submarine frigates. The established requirement stands at eight. The committee raised parallel concerns regarding the availability of destroyers and attack submarines. It urged the government to establish a readiness improvement plan ahead of 2030.
The Navy is advancing a hybrid fleet model. It features an autonomous squadron in Portsmouth and uncrewed surface vessels. Upcoming trials test a carrier-capable uncrewed aircraft demonstrator.
