The United Kingdom plans to build at least six new warships designed to coordinate drones and other autonomous vessels as part of a significant shift in its naval strategy. These “common combat vessels” (CCVs) are intended to replace aging destroyers and frigates within the Royal Navy’s fleet, with deliveries expected in the 2030s. The announcement accompanies the release of the government’s long-delayed ten-year defence investment plan (Dip), which was finalized amid internal disputes over funding and strategic priorities.

The new vessels will act as hubs for uncrewed systems, including underwater drones and sensor platforms, reflecting concerns about increased Russian submarine activity in the Atlantic, particularly near strategically important undersea cables. The CCVs are designed to expand operational reach and firepower without a corresponding increase in crew size or costs and will operate alongside eight Type 26 and five Type 31 crewed frigates. However, previous proposals to develop a new class of guided-missile Type 83 destroyers have been dropped from the plan.

The defence investment plan, originally due last year, faced delays amid repeated ministerial clashes over budgets, culminating in the resignation of former Defence Secretary John Healey. The overall budget has increased by £1.5 billion to £15 billion, though defence officials maintain this still falls short of the estimated £28 billion funding gap over the next four years. New Defence Secretary Dan Jarvis emphasized that the CCVs will be British-built and represent a forward-looking capability for modern warfare. First Sea Lord General Sir Gwyn Jenkins described the programme as part of a broader transition toward a “hybrid navy” combining crewed ships, submarines, and autonomous vehicles supported by artificial intelligence.

The plan also includes initiatives such as three Atlantic-focused programmes—Atlantic Bastion, Atlantic Shield, and Atlantic Strike—aimed at countering Russian activities in the North Atlantic and High North. Additionally, £500 million is earmarked to support the Royal Marines, and £580 million is allocated to enhance research on biological threats at the Defence Science and Technology Laboratory’s Porton Down site.

While some welcome the integration of advanced unmanned systems, others express concern that the move to fewer, lighter-armed CCVs risks weakening the Royal Navy’s surface warfare capabilities. Critics argue that drones and autonomous vessels should complement—not replace—larger, heavily armed warships essential for tasks such as aircraft carrier escort, ballistic missile defence, and protection of maritime trade routes. Observers point out that other NATO members continue to invest robustly in both traditional ships and autonomous technologies, highlighting the UK’s relative decline in defence spending as it falls below the recommended 3 percent of GDP.

The forthcoming change in prime ministerial leadership has also raised discussions about the plan’s future. Sir Keir Starmer is set to announce the Dip before potentially handing over to Andy Burnham, who has been briefed on its broad outlines but does not yet have full security clearance. Some believe the financial and strategic implications may prompt Burnham to revisit certain aspects once in office.

Senior military figures warn that evolving global threats may require increased defence funding during this parliamentary term to ensure the UK’s armed forces remain capable in an era of rapid technological change and geopolitical competition.
