The United Kingdom announced Tuesday the deployment of military assets for a defensive mission aimed at securing freedom of navigation in the Strait of Hormuz. While the decision represents a step toward mending relations with Washington, Prime Minister Keir Starmer’s refusal to join the United States in “Operation Epic Fury” against Iran has generated significant friction with President Donald Trump. The American leader dismissed Starmer as “no Churchill” and publicly criticized British military readiness during recent White House meetings.
Trump expressed frustration over the lack of British support during a Sky News interview. “When we asked them for help, they were not there. When we needed them, they were not there… And they still aren’t there,” the president stated. Trump also mocked the Royal Navy’s capabilities in March, calling British aircraft carriers “toys compared to what we have” during discussions about potential deployment to the Middle East region.
Military experts reveal decades of systematic underfunding
Two recent comprehensive reports shed light on why Britain opted out of offensive military action against Iran. Matthew Savill, director of military sciences at the Royal United Services Institute (RUSI), authored a report titled “Iran War Delivers a Tough Lesson in Hard Power to the U.K.” that outlined the practical constraints facing British armed forces. Savill noted that pressure is growing for increased deployment to the region, but the government must answer difficult questions about prioritization and realistic achievable effects.
The RUSI director emphasized that U.K. commitments and visible military presence in the Middle East have been shrinking in recent years due to pressure on the military and conscious decisions to prioritize elsewhere. The “NATO First” approach adopted in the Strategic Defense Review of 2025 redirected resources away from global deployments. On the defensive side, British assets including counter-drone units have been involved in downing Iranian drones while defending Jordan and Iraq, demonstrating limited but focused engagement.
Royal Navy strength reduced by half over three decades
John Hemmings, director of the National Security Center at Henry Jackson, provided detailed analysis of the decline in British military capabilities. The expert told media outlets that U.K. armed forces have been systematically underfunded over the past 15 years, with spending cuts starting in 2009 and 2010 under Prime Minister David Cameron. The Strategic Defense and Security Review at that time acknowledged the world was becoming more dangerous, yet fiscal devastation from the 2008 financial crisis pushed the government into cuts intended to be temporary.
The Royal Navy has suffered particularly dramatic reductions in fighting capability. Current fleet composition includes only 25 out of 63 commissioned vessels as actual fighting ships. In 1996, the service operated 22 frigates, 17 submarines, 15 destroyers, and three aircraft carriers. Today’s First Sea Lord must fulfill the same global responsibilities with just seven frigates, 10 submarines, six destroyers, and two aircraft carriers. This represents a 50% reduction in force size over 30 years, making it impossible to service Britain’s overseas responsibilities adequately.
- Seven frigates currently operational, down from 22 in 1996
- Ten submarines available, compared to 17 three decades ago
- Six destroyers in service, reduced from 15 in the mid-1990s
- Two aircraft carriers operational, versus three in 1996
- Only 25 actual fighting ships out of 63 commissioned vessels
Parliamentary committee warns of dangerous U.S. dependency
The House of Lords International Relations and Defense Committee released a report last month titled “Adjusting to new realities: rebalancing the U.K.-U.S. partnership” that presented several critical recommendations. The committee warned that although Britain has benefited from close collaboration with the United States on defense matters, this relationship has fostered a dependency culture leading to decline in U.K. capabilities and loss of credibility in Washington. The report called for a clear and costed pathway to achieving the commitment to increase defense spending to 5% of GDP.
The assessment highlighted that Britain has underfunded new capabilities including domestic air and missile defenses along with advanced command and control systems. The strategic implications affect not only current operations but also long-term ability to project power globally. Analysts suggest that while some in the Trump administration view the U.K.’s absence from Iran operations as betrayal of the special relationship, others recognize it as a lesson in the limitations of a mid-sized power attempting to maintain global footprint on a shrinking budget.
Government pledges largest defense spending increase since Cold War
The Starmer government has committed to increasing defense spending to 2.5% of GDP by 2027, with total armed forces strength standing at 182,050 personnel as of January 1, 2026. This includes 136,960 regular troops, representing an increase from the previous year and reversing what officials describe as an attrition rate in military recruitment and retention. The government announced plans for what it characterizes as the largest sustained rise in defense spending since the Cold War era.
Military spending is set to reach 2.6% of GDP by 2027, backed by an additional £5 billion (approximately $6.6 billion) this financial year. Total defense investment over the course of the current parliament is projected at £270 billion (nearly $360 billion). Britain has also stated it aims to raise defense spending to 3% of GDP by the end of the next parliament. However, experts caution that this investment may arrive too late to restore the country’s ability to project power globally in the near term, given the scale of capability gaps that developed over previous decades of underinvestment.
