Britain’s delayed Defense Investment Plan, due for publication later Tuesday, puts drones and uncrewed systems at the center of a future military—while a hard dispute over spending levels leaves lawmakers and opposition arguing over whether the country is doin
London woke up to the promise of a new defense road map, but the real story behind Britain’s future military is the fight over money—one that has already cost the country a defense secretary.
Self-flying fighter jets, uncrewed submarines and drones are expected to anchor Britain’s Defense Investment Plan, being announced Tuesday. The shift toward autonomous systems reflects how the world’s conflicts are being rewritten by technology. Yet the plan has been repeatedly delayed as military leaders and Treasury officials wrestled over what it would cost to equip the U.K. forces for a more dangerous era.
John Healey resigned as defense secretary on June 11. accusing the government of not willing to spend enough on the military amid “rising threats.” His argument was blunt: U.K. defense spending should reach 3% of GDP by 2030. Healey pointed to a British intelligence assessment that Russia could attack a NATO member country by that time.
In Healey’s account, the plan proposed by the Treasury would lift spending to 2.68% of GDP in 2030, after hitting 2.6% next year.
The government says the spending plan has been “refocused” in the past few weeks under Healey’s successor. Defense Secretary Dan Jarvis. That refocusing includes more money than the 13.5 billion pounds ($18 billion) Healey said he was offered. but it is likely far less than the 28 billion pounds ($37 billion) defense officials had called for.
Prime Minister Keir Starmer said the plan will ensure “our servicemen and women have the cutting-edge capabilities they need to deter evolving threats and keep the British people safe.” The full document is due to be published later Tuesday.
Starmer’s assurances land in a wider pressure campaign. Like other NATO countries, the U.K. is being pushed to increase defense spending to counter a more aggressive Russia and a less reliable United States. Britain. in particular. has watched how drones have reshaped war in Ukraine—where that country uses 200. 000 drones a month to defend against Russian forces.
The plan’s technology emphasis is meant to go beyond slogans. Britain intends to invest billions in drone systems across all branches of the military. Instead of a planned fleet of new destroyers, the Royal Navy will receive hybrid vessels that will function as command hubs for drones.
The spending fight also sits inside a broader alliance dispute. Britain and other NATO members have faced pressure from U.S. President Donald Trump to increase military spending. Trump has long questioned the value of the NATO alliance and complained that the United States provides security to European countries that do not pull their weight.
By design, the Defense Investment Plan is a road map for bringing U.K. spending to NATO’s target of 3.5% of GDP by 2035. It comes as Britain’s military seeks to reverse years of decline while Russia’s actions in Europe grow more assertive. Russia invaded Ukraine in 2022 and has increasingly tested European defenses with both overt and covert activity.
The personal fallout around the plan has been just as consequential as the policy itself. Healey’s resignation. along with the resignation of junior Defense Minister Al Carns. were among a series of blows that prompted Starmer to announce last week that he will resign. He is likely to attend a NATO summit in Turkey on July 7 and 8 in one of his last acts as prime minister.
Starmer’s successor—likely the former Greater Manchester Mayor Andy Burnham—is expected to inherit the problem the plan is trying to solve: how to commit to long-term defense upgrades without running into the same budget wall that derailed earlier timelines.
In Parliament, the opposition is already trying to frame the plan as insufficient. Opposition Conservative Party defense spokesperson James Cartlidge said it was “too little. too late.” He added: “The plan is now almost a year overdue and only being rushed through because Keir Starmer is desperate for a legacy.”.
Whether the new Defense Investment Plan closes that gap—or deepens the divide—will likely be decided not in the language of the rollout Tuesday, but in what the promised spending levels actually allow Britain to build next.

So basically drones are the new fighter jets? Cool I guess… wait where’s the money coming from then?
Britain delayed it again because they can’t decide on the spending like always. Meanwhile people act like self-flying stuff is automatically “safer” but I’m like… Russia still gonna Russia.
Healey quit over it and they say it’s “refocused” now… so did they just fire him because he wanted the 3% GDP thing? 2.68% vs 3% sounds like the same to me, like what’s the difference? Also drones in the fight sounds like Star Wars propaganda.
Every time they talk about “autonomous systems” it feels like nobody’s asking the public if we even want that. Then it’s all this NATO Russia timeline stuff and lawmakers arguing numbers in pounds like that fixes anything. If the defense secretary resigned, does that mean they already had the plan but were stalling on purpose? London woke up to the road map lol but they still can’t road map spending.
