Defense Spending Concerns Emerge Amid Shrinking UK Military
Following recent assessments of the UK’s security posture, former NATO secretary general Lord Robertson has raised alarms, claiming the government’s Strategic Defence Review (SDR) jeopardizes national defense. He argues that reliance on growing welfare budgets is insufficient to safeguard Britain, asserting that “We cannot defend Britain with an ever-expanding welfare budget,” as per a

in the controversy.
UK Military Forces: A Decade of Reductions
Since the end of the Cold War in 1990, the UK military has undergone significant downsizing. The army, which once fielded 153,000 regular soldiers, now stands at 73,790. The 2025 SDR aims to stabilize the British Army’s strength at 73,000, yet the Ministry of Defence (MoD) reported a 40% decline in recruitment applications in 2025 compared to 2024.
The Royal Navy has also seen a reduction in its fleet, with 48 major combat ships in 1990—comprising 13 destroyers and 35 frigates—now down to 11 frigates and 6 destroyers. A recent incident highlighted concerns over naval readiness, as HMS Dragon took weeks to reach the Gulf to support a Royal Air Force base in Cyprus.
The RAF, once boasting over 300 combat jets, now operates 137 Eurofighter Typhoons and at least 37 F-35 Lightning II aircraft. These newer models are more advanced than their predecessors, though the force’s overall size has shrunk. Uncrewed aircraft systems, or drones, have emerged as a critical component of modern air capabilities—a development unseen in 1990. Their impact in the Ukraine conflict, where they surpass traditional artillery in lethality, has underscored the need for greater investment in such technologies.
Government’s Defense Spending Ambitions
In response to criticism, the government claims it is set to increase defense spending to 2.5% of GDP by April 2027. This target, however, is seen as modest given the long-term decline in defense budgets since the fall of the Berlin Wall. The plan includes an “ambition” to reach 3% of GDP on defense during the next parliamentary session.
Lord Robertson specifically contrasts defense funding with welfare expenditures. While mid-1980s spending on working-age benefits was lower than on defense, current figures show the reverse, with benefits projected to rise to 4.3% of GDP by the end of the decade. This increase is driven by higher claims for Personal Independence Payments (PIP), though the exact causes of this trend remain debated among researchers.
Procurement Challenges and Project Delays
The MoD manages some of the UK’s largest procurement initiatives, overseeing 47 of the 213 Government Major Projects Portfolio (GMPP) in 2024-25. A National Audit Office (NAO) report revealed that 12 of these projects were rated ‘Red,’ indicating their success is “unachievable” under current timelines. The NAO also noted that the MoD typically takes six and a half years to award contracts for projects exceeding £20 million, highlighting systemic delays.
The 2025 SDR proposed a “segmented approach” to streamline defense procurement, aiming to complete contracts within two years. Analysts cite rising threats from Russia since 2022, the Middle East conflict, and uncertainties about U.S. NATO commitments as reasons for the UK to boost its defense investment. Meanwhile, the MoD’s plans to meet NATO’s 5% GDP national security target by 2035—split into 3.5% for core defense and 1.5% for infrastructure and civil preparedness—have drawn scrutiny.
