The Pentagon says all 12 B-1 bombers have left RAF Fairford

The United States has removed every bomber it had at RAF Fairford. A Pentagon spokesman said on Sunday that all US bombers deployed to the Gloucestershire base had gone back to their home stations in the United States. A dozen B-1B Lancers had been there. They left over the course of Sunday, aircraft spotters told Air and Space Forces Magazine, and US European Command confirmed the departure.

The move came a week after arrests at and around the base. Six people have been held on suspicion of preparing terrorist acts. Prime Minister Andy Burnham said on Wednesday that Britain had strong indications Iran was involved in a suspected plot against Fairford. Iran called the accusation baseless and summoned the British ambassador in Tehran. The Wall Street Journal reported the aircraft removal first. The Pentagon email, quoted by Reuters, said operational security had kept the movement quiet in real time, and that it could now be acknowledged.

What the base was for

Fairford, north-west of London, is the US Air Force's bomber bed-down in Britain. During the peak of Operation Epic Fury the United States had about two dozen bombers there at once, some 18 B-1s and half a dozen B-52s, Air and Space Forces Magazine reported. The B-52s left months ago. Since a shaky ceasefire with Iran in April, the remaining B-1s had mostly flown training sorties. Before that, Britain had allowed bombers at Fairford to strike Iranian missile sites that were firing on ships in the Strait of Hormuz.

A B-1 does not need Fairford to reach the Gulf. It needs a base, tankers, and a political permission. Sending the 12 home removes the aircraft from a site British police are still treating as a target. It also removes the most visible US strike asset on British soil. Training flights from the continental United States can replace some of that presence. They cannot replace the alert posture of jets already in Gloucestershire.

The B-1B carries a conventional load and has been the workhorse of the Iran strikes flown from Britain. Ellsworth Air Force Base in South Dakota and Dyess in Texas are the US homes for the type. A redeployment to home station, in Pentagon language, means those wings, not a third country. Spotters at Fairford recorded the departures across a single day, which is fast for 12 heavy aircraft that need tankers and a route clear of civilian corridors.

The arrest count and the Iranian denial

Six arrests is the figure given by Air and Space Forces Magazine for the suspected plot. Reuters said several men were arrested on suspicion of preparing terrorist acts. Burnham's phrase, strong indications of Iranian involvement, is a political claim short of a criminal charge. Tehran's response was a summons, which is the standard diplomatic reply to an accusation of this kind. No indictment naming an Iranian official has been reported.

The timing is still tight. Wednesday: the prime minister links the plot to Iran. Sunday: the bombers are gone, and the Pentagon confirms it. A hostile service that wanted the aircraft moved has, on this sequence, watched them move. A service that wanted them destroyed has watched them leave intact. Both readings are available. The Pentagon has not said the departure was ordered because of the plot. It has said the departure happened, and the plot is the context every British and American account places next to it.

What stays at Fairford

The base does not close because the B-1s leave. Tankers, maintainers and a runway built for heavy aircraft remain. The question for the next week is whether any bomber returns, or whether Fairford goes back to the quieter tempo it had before Epic Fury. Spotters who watched 12 departures in a day have a checklist. A single B-1 on approach would be the sign that the Pentagon has decided the security concern is managed. Until then, the strike aircraft that were using British concrete to reach Iranian targets are back on American concrete.

For London the departure is also a hosting question. Britain authorised the use of Fairford against Iranian missile sites. That authorisation is harder to defend if the base is treated as an active target and the aircraft have to leave for their own safety. Burnham's government now has a week of arrests, a public Iranian denial, and an empty bomber ramp. The next statement that would change the picture is either a charge that names a foreign service, or a Pentagon note that bombers are coming back.
