US Gathers Troops, Jets at UK Bases Despite Refusal on Iran Strikes

The United States has been quietly amassing military personnel and aircraft at several bases in the United Kingdom and nearby regions even as the British government declined to permit the use of its facilities for potential airstrikes on Iran, officials and analysts say. The buildup highlights growing tensions between NATO allies over how to respond to Tehran’s nuclear ambitions and broader regional security challenges.
According to open‑source flight tracking data reviewed by analysts, at least 28 U.S. military flights have operated from airfields in Britain and Cyprus in recent days amid a broader surge of personnel, fighter jets, bombers, and support aircraft bound for Europe and the Middle East.
A Surge Despite UK Refusal
British Prime Minister Keir Starmer has refused formal requests from Donald Trump’s administration to allow American forces to launch offensive operations from UK territory, especially for a potential strike on Iranian targets. Under long‑standing bilateral defence agreements, the U.S. may use UK airbases routinely—such as RAF Lakenheath and RAF Mildenhall—but approval is required for combat operations aimed at third countries.

The British government has repeated that no authorization has been granted for strikes from bases including RAF Fairford in England or RAF Akrotiri in Cyprus. Officials have cited concerns about international law and the legal implications of facilitating offensive action from sovereign soil.
Despite this refusal, American strategic aircraft—including tankers, AWACS surveillance planes, and advanced fighters—continue to fly into UK and Cypriot facilities, where they can be refuelled, serviced, and repositioned for eventual deployment to the Middle East if needed.

Diplomatic Friction and Chagos Controversy
The dispute over base access has spilled into broader diplomatic disagreement between London and Washington, particularly over the future status of Diego Garcia, a strategically vital base in the Indian Ocean currently leased to the United States. Reports say President Trump has publicly criticised the UK government’s reluctance, linking it to opposition over sovereignty transfers for the archipelago.
Trump had previously suggested that Diego Garcia and RAF Fairford might be needed “to eradicate a potential attack by a highly unstable and dangerous regime,” a reference to Iran’s nuclear programme, but Starmer’s administration has stood firm in withholding permission.
Wider Military Build‑Up
The U.S. deployment is part of a larger strategic repositioning. Alongside the movements in Britain, American aircraft carriers—including the USS Abraham Lincoln and anticipated arrival of others such as the USS Gerald R. Ford—have been sailing toward the eastern Mediterranean and Arabian Gulf.
Defense analysts say this muscle‑flexing aims to give Washington maximum flexibility: deterrence, regional stability, and readiness for rapid escalation if Tehran refuses diplomatic overtures over its nuclear programme. At least six E‑3 AWACS surveillance aircraft were reportedly repositioned toward the region, alongside dozens of combat and support jets.
UK’s Support for Diplomacy
Despite the military build‑up, the British government has signalled a different approach. Yvette Cooper and other ministers have called publicly for renewed negotiations with Iran, urging that diplomacy and economic pressure remain the primary tools for addressing the standoff.
Cooper’s comments reflect wider UK policy that emphasises international law and collective security mechanisms, even as London underscores the shared priority with Washington that Tehran should not develop nuclear weapons.
Tensions and Strategic Calculations
The situation places the United States in a delicate strategic position. Preparing forces for potential action while not having guaranteed access to key allied facilities complicates operational planning, particularly for long‑range bombers. Yet the buildup of troops and jets suggests Washington is preparing to act unilaterally if it deems necessary.

For its part, the UK must balance its legal and diplomatic principles with maintaining a historic defence partnership with the United States—a challenge now intensified by questions over whether military action against Iran is imminent.
