Trump confirms 'threat' prompted US bomber withdrawal from RAF Fairford

The Pentagon moved roughly a dozen B-1 bombers out of RAF Fairford in Gloucestershire and back to their home stations in America, a decision President Trump confirmed on Monday was driven by security concerns rather than routine rotation. Speaking to reporters as he prepared to depart for Nebraska, Trump said the aircraft had not left by accident—there were threats, he explained, and rather than leave the expensive, sensitive planes exposed, the US decided to relocate them. He added that Washington knew who had made the threat but declined to say more.

The withdrawal followed an incident on September 27 when police responded to three suspicious vehicles near the airbase and launched a counter-terrorism investigation. Five men were arrested on suspicion of terror offences and later released on bail; a sixth man, identified as a UK-Iranian national, was also arrested and released on bail. Trump criticized the decision to release the first five men, and US officials began suggesting Iran could have been involved.

The exact nature of the threat remains officially unconfirmed, but sources in Washington told the BBC it likely centered on sabotage attempts or strikes against the aircraft themselves. One White House source pointed to Ukraine's Operation Spiderweb—a covert drone attack on five Russian bases in June of the previous year—as an example of what an adversary could accomplish even from a distance. US media outlets including the New York Times, Wall Street Journal, and Axios reported, citing unnamed officials, that the potential attack may have been designed to damage the bombers and kill personnel. Whatever the specific concern, the source said, it was treated with extreme seriousness.

Trump's public acknowledgment of a threat stood in contrast to the more cautious language used by Secretary of State Marco Rubio, who characterized the bomber movement as routine. Rubio noted it was not unusual for military units and assets to rotate around the world based on exercises and redeployments. He said the US retained full confidence in the security of all its bases and praised British authorities for their cooperation since the incident. Vice President JD Vance later described the decision as an "abundance of caution," suggesting Washington believed Iran was continuing behavior it had pursued for decades—acts of terrorism against the US and others.

Prime Minister Andy Burnham said days after the incident that there were "strong indications" Iran had played a role, though he offered no specifics. Rubio acknowledged the incident "clearly involve[d] the hands of a foreign actor" without elaborating. Tehran has categorically denied involvement. In July, Iran had declared that "any base used for aggression against Iranian territory constitutes a legitimate target for our forces."

RAF Fairford, located near the village of Whelford, has served as a forward operating location for the US Air Force for decades. In recent months, B-1 and B-52 bombers have flown from the base for operations in the Middle East after the UK approved US requests to use it for defensive strikes on Iran. The redeployment will reduce America's capacity to rapidly surge sorties against Iran, according to Christoph Bergs, a research analyst at the Royal United Services Institute. However, that capacity had already been constrained by London's requirement that the base be used only for defensive operations. The relocated aircraft could potentially be stationed at Diego Garcia or bases in the Gulf, though such moves would depend on available capacity, negotiations with allies, and security considerations.
