United Kingdom is preparing to abandon long-standing plans to replace its ageing Type 45 destroyers with a new class of traditional warships, opting instead for a fleet of at least six advanced hybrid combat vessels designed to operate alongside drones and autonomous systems as part of a sweeping overhaul of Britain’s military strategy.

The significant change, expected to feature prominently in the government’s long-delayed Defence Investment Plan (DIP), reflects a growing belief within the Ministry of Defence (MoD) that future conflicts will rely less on a small number of heavily crewed, high-cost warships and more on flexible, technology-driven platforms capable of coordinating autonomous operations across multiple domains.

Rather than continuing development of the proposed Type 83 destroyer a concept vessel intended to replace the Royal Navy’s current Type 45 fleet the government has decided to invest in at least six Common Combat Vessels, which defence officials say will deliver greater operational flexibility while reducing long-term costs and personnel demands.

According to the Ministry of Defence, the new vessels will be specifically designed to deploy and coordinate uncrewed systems operating in the air, on the sea surface and beneath the water, creating an integrated combat capability suited to the realities of modern warfare.

The Ministry of Defence indicated that the hybrid ships would provide “more resilient air defence” while extending “the Navy’s reach, resilience and firepower without a proportional increase in crew or cost.”

The vessels are expected to play a central role in protecting British and allied interests in strategically important waters, including operations aimed at countering Russian naval activity in the North Atlantic and the High North, safeguarding critical underwater infrastructure such as communication cables and energy pipelines, and strengthening NATO’s collective deterrence posture.

Although the Ministry has not disclosed how much funding has been allocated for the programme, officials described the initiative as part of a “once in a generation investment in new maritime capability.”

Alongside additional support ships, the project is also expected to generate significant work for British shipyards, providing a boost to the domestic defence industry while modernising the Royal Navy’s fleet.

The decision comes amid a long-running political dispute over Britain’s defence spending priorities. The Defence Investment Plan has been delayed for months as ministers negotiate budget levels with the Treasury, exposing internal divides within the government about how quickly military investment should expand in response to emerging threats.

Those disagreements recently led to the resignations of Defence Secretary John Healey and Armed Forces Minister Al Carns, both of whom argued that the proposed spending plans fell short of what Britain’s armed forces require.

Healey warned that Prime Minister, Keir Starmer had been “unable” and the Treasury “unwilling” to provide the resources necessary to strengthen Britain’s military at what he described as “this time of rising threats.”

Carns similarly criticised the draft strategy, stating that it was “neither transformative enough nor sufficiently funded.”

The appointments of a new defence leadership team have since raised expectations that additional resources could be secured before publication of the final strategy.

Defence Spending Focus Shifts to Emerging Technologies

Defence Secretary Dan Jarvis has positioned the revised investment plan as a decisive break from traditional procurement approaches, arguing that Britain’s armed forces must be equipped to respond to rapidly evolving security challenges.

Announcing the shift toward the Common Combat Vessel programme, Jarvis revealed that the new fleet would be “designed and built for the increasing threats we face.”

Earlier, the Ministry of Defence unveiled a separate £500 million package to provide Britain’s elite Commando Force with new boats as well as cutting-edge drone and autonomous technologies.

Along with other NATO countries, UK government has pledged to raise defence spending to 2.5% of GDP by 2027 and to support a longer-term goal of 3.5% of GDP by 2035.

However, according to NATO’s most recent data, Britain’s defence spending in 2025 was 2.3% of GDP, which is just less than the alliance average when US expenditures is taken out.

Healey disclosed in his resignation letter that the version of the Defence Investment Plan that was in place at the time he left office predicted that defence spending would only amount to 2.68% of GDP by 2030 much less than what he believed was required to get Britain ready for future conflicts.

Despite the political disagreements surrounding the strategy, the government remains determined to publish the long-awaited Defence Investment Plan before the NATO summit in Turkey on 7 July, where alliance members are expected to discuss collective security priorities and long-term defence commitments.
