Cash-strapped British military embarks on radical new course

Following London’s belated publication of a long-awaited, highly controversial Defense Investment Plan, political and defense circles in Britain are in an uproar, with the prime minister and the opposition leader sparring Wednesday in fiery exchanges in Parliament.

Depending on whom you ask, the “transformational” DIP is either bold and radical, or relies too heavily on unproven unmanned technologies that require America’s leading ally to fight a Ukraine-style poor-man’s war.

Since the 81-page DIP was released on Tuesday, politicians, pundits and the media have been furiously debating it — particularly its budget shortfall and its striking plans for the future Royal Navy.

The debate reflects ongoing turmoil in Britain’s defense, bureaucratic and political establishments.

It is back-dropped by a recent national humiliation. At the outset of the Iran conflict, Britain’s once-vaunted Royal Navy was found incapable of swiftly deploying a warship to the crisis zone.

Agonized funding, delayed release

The DIP lays out funding called for in June 2025’s Strategic Defense Review. It has had a long, troubled gestation, only to finally appear amid a leadership crisis.

Originally expected in the fall of 2025, the DIP was repeatedly delayed amid a funding fight that pitted the Ministry of Defense against the Treasury.

The latter was reportedly angered by the MOD’s history of delivering faulty projects late and over-budget.

On June 11, defense chiefs acted.

Secretary of State for Defense John Healey and his deputy, Armed Forces Minister Al Carns, resigned in protest of the funding shortfall.

That piled pressure onto Prime Minister Keir Starmer, who led the Labor Party to a decisive general election victory in June 2025 but whom polls now find to be hugely unpopular.

On June 22, prime-minister-hopeful Andy Burnham, having just won a by-election, made clear that he would challenge for the leadership of the party (hence also the country).

The same day, Mr. Starmer announced that he would not fight the challenge. He will head a caretaker government until the party confirms a new leader.

So far, no other candidate has appeared, offering Mr. Burnham a “coronation” in mid-July. However, Mr. Carns, a charismatic former Royal Marine Commando, has hinted that he may step up.

In that case, the winner would take office in September. The Labor Party’s electoral term expires in August 2029.

“This plan commits more investment in our armed forces — £298 billion pounds ($395 billion) over the next four years — that includes an additional £15 billion on top of last year’s spending review settlement, of which most is extra day-day spending on training and availability of ships and aircraft,” Dan Jarvis, who was appointed Defense Secretary on June 11, told Parliament Tuesday.

That represents a modest win.

“That is £1.5 billion more than when I took on this job just a couple of weeks ago,” the former paratroop officer said.

“We made some difficult but necessary decisions to fund this,” Mr. Jarvis revealed, noting that government agencies had been required to surrender some allocated funds to defense.

On Wednesday in Parliament, Conservative Party Leader Kaemi Badenoch took aim at Mr. Starmer during Prime Minister’s Questions.

She called the DIP “too weak, too little, too late,” and accused him of leaving a budget shortfall in the DIP of almost $7 billion for his successor. Calling it “a mess,” she demanded where that cash would come from.

According to The Guardian, an unnamed ally of Mr. Burnham has called the DIP’s budget hole “an unexploded bomb.”

Mr. Burnham did not attend PMQ, and has stayed mum on the DIP — perhaps for good reason.

A party member familiar with the 2017-2026 mayor of Manchester told The Washington Times that he had never once heard Mr. Burnham discuss either foreign policy or defense.

Ms. Badenoch urged Mr. Starmer to fill the DIP cash gap from welfare funds.

Mr. Starmer returned fire, accusing Conservative administrations of “hollowing out” defense and calling the DIP the biggest defense-spending upgrade in 40 years.

It looks less impressive on a per-capita basis. It represents 2.7% of GDP by 2030 while NATO’s mandate is 3%, and offers no clear path toward the 3.5% of GDP called for by NATO for 2035.

What is Britain buying?

Among the DIP’s standouts are the doubling of nuclear weapon delivery options.

For decades, London’s sovereign nuclear deterrent has been based solely on Trident-equipped nuclear submarines. Now, with nuclear superpower Russia fighting a devastating war in Europe, the Royal Air Force, too, will take a role.

Ten nuclear-capable F-35As — a different variant to the 48 F-35Bs that make up London’s existing stealth fighter force — will be acquired by the early 2030s. Some $84 billion will be spent on these, along with new nuclear submarines and nuclear sub maintenance facilities.

Funding of $12 billion has also been confirmed — there had been jitters that it would not be — for a sixth-generation stealth fighter program Britain is developing with Italy and Japan.

The RAF’s current wing of Typhoon fighters will also gain a $1.3 billion upgrade, and investments were announced in drone wingmen to fight alongside manned jets.

On land, $15 billion will be spent replenishing weapons and munitions, from infantry anti-tank rockets to mobile artillery, that London sent to Ukraine, while $4.4 billion will be spent on tanks and all-terrain vehicles.

Air defense will require another $1 billion to pay for sensor arrays and anti-drone weapons, but London’s capability to down ballistic, and particularly hypersonic missiles, remains questionable.

Mr. Carns has warned British forces to prepare for the “next war, not the last” and the most striking changes in that sphere are to the Royal Navy.

It will get new submarines and frigates, but a planned new destroyer flotilla has been nixed. Instead, the Royal Navy will get at least six “Common Combat Vessels” — hybrid warships controlling organic squadrons of air, surface and underwater drones.

Funding is also allocated for aircraft carrier drones and mine-hunting drones.

Unmanned systems solve recruitment shortfalls, and slash political risks for governments, which may suffer popularity drops if body bags mount up.

But the DIP’s pivot away from manned surface warships to unmanned systems has generated controversy. So, too, has the document’s heavy focus on Ukraine’s combat experience.

“Britain needs a Navy to control the seas around it for its security and prosperity, not just deny their use to an adversary as Ukraine has done,” wrote ex-Royal Navy officer John Foreman, who commanded two ships in his career, in The Spectator magazine.

“Much of the [unmanned] technology remains unproven at sea,” he added, noting the need for “extensive and realistic trials for which the Navy scarcely has enough sailors and ships to spare.”

New capabilities, “will have to be proven and operational in less than 10 years,” stated independent specialist media Navy Lookout on X, adding that the $1.7 billion budget looks insufficient.

Navy Lookout called the changes “Full speed into the unknown,” while Mr. Foreman warned, “Britain cannot afford to mistake experimentation for transformation.”
