WASHINGTON, DC – October 6, 2026 (STL.News) The United States removed all 12 B-1B Lancer bombers deployed at RAF Fairford in Britain because of concerns about a suspected plot involving Iran to launch a complex drone attack against the base, according to two U.S. officials cited by Reuters.
The officials, who spoke on condition of anonymity because of the matter’s sensitivity, said concerns about the suspected attack prompted the United States to remove the aircraft from RAF Fairford, the principal European operating location for American bombers.
Iran has denied involvement in any alleged plot against the base.
The disclosure provides the clearest explanation yet for the sudden departure of the entire remaining B-1B contingent from Fairford on Oct. 4.
The Pentagon and U.S. European Command have confirmed that all American bombers deployed at Fairford returned to their home stations in the United States.
European Command, however, has declined to publicly discuss the intelligence behind the decision or specific measures taken to protect the aircraft.
The development comes as British counterterrorism authorities conduct a widening investigation into suspicious activity near RAF Fairford that has resulted in seven arrests.
The British investigation remains active, and authorities have not publicly established that Iran directed the people arrested or that the suspects were preparing the drone attack described by the two U.S. officials.
No suspect has been convicted in connection with the investigation.
All 12 B-1 bombers leave Britain
The dozen B-1B Lancers remaining at RAF Fairford departed during Oct. 4 in an unusually rapid movement of the deployed bomber force.
The U.S. military subsequently confirmed the redeployment.
“All U.S. bombers that were deployed to RAF Fairford have redeployed to their home stations in the United States,” the Pentagon and U.S. European Command said in statements provided to Air & Space Forces Magazine.
The military emphasized that returning the aircraft to the United States does not eliminate America’s ability to conduct long-range bomber missions.
European Command said America’s B-1, B-2 and B-52 bombers remain capable of conducting precision global strike operations, including missions launched from and recovered at bases in the continental United States.
The command declined to discuss the threat itself.
“It is inappropriate to discuss matters of intelligence, and we will not discuss specific force protection measures,” a European Command spokesperson told Reuters.
The explanation provided by two U.S. officials is nevertheless significant.
According to Reuters, the officials said a suspected plot involving Iran to conduct a complex drone attack against the British base prompted the United States to remove the B-1s.
Iran has denied involvement.
British investigation began Sept. 27
The events surrounding RAF Fairford began during the early morning hours of Sept. 27.
At approximately 12:45 a.m., police received a report concerning three suspicious vehicles that appeared to be traveling toward RAF Fairford, according to Counter Terrorism Policing and Gloucestershire Constabulary.
Armed officers responded and arrested five men in the Whelford area on suspicion of offenses under Britain’s Explosives Act.
The men were subsequently also arrested on suspicion of preparation of a terrorist act under Section 5 of the Terrorism Act 2006.
Authorities established a 400-meter cordon around the vehicles while the Army’s Explosive Ordnance Disposal unit examined them.
Authorities advised approximately 85 households to evacuate as a precaution.
Counter Terrorism Policing then assumed control of the investigation.
Military assets and forensic experts extensively examined the vehicles.
Authorities later announced that no improvised explosive devices had been discovered.
Police did, however, recover a quantity of petrol.
Police released the five men on bail Sept. 28, subject to what Counter Terrorism Policing described as stringent conditions on their movement and contact with others.
Authorities emphasized that their release did not end the investigation.
Investigation expands to London
The investigation subsequently widened.
On Oct. 1, British authorities arrested a 25-year-old dual UK-Iranian national in London on suspicion of preparing terrorist acts.
Police later released him on bail.
Counter Terrorism Policing announced another arrest on Oct. 6.
A 22-year-old British national was arrested in the Borough of Westminster in London on suspicion of preparing terrorist acts under Section 5 of the Terrorism Act 2006.
Officers also searched a property in Westminster.
The latest arrest brings the total number of people arrested during the investigation to seven.
The six previously arrested men remain on police bail.
The 22-year-old arrested Tuesday remained the latest suspect in the continuing investigation at the time of the police announcement.
All allegations remain unproven. The suspects are presumed innocent unless and until proven guilty in court.
Police still trying to establish motive
British counterterrorism authorities have been careful not to publicly conclude who may ultimately have been responsible for the activity near Fairford.
Vicki Evans, senior national coordinator for Counter Terrorism Policing, said Oct. 6 that investigators continue to pursue “multiple lines of inquiry” surrounding the events.
Authorities are working to establish the motivation behind the activity and say they remain committed to investigating all possible explanations.
Earlier in the investigation, Assistant Commissioner Laurence Taylor addressed speculation that the international geopolitical situation could be connected to the case.
Taylor said investigators were keeping an open mind and examining the incident from every possible angle.
He specifically said investigators were considering whether the activity could have involved proxies or individuals knowingly or unknowingly working on behalf of a foreign state.
That is an investigative possibility — not a police finding that Iran directed the alleged activity.
The distinction is important.
Reuters’ latest reporting concerns the intelligence assessment that influenced the American military decision to move the bombers.
Two U.S. officials said fears of a suspected Iranian drone plot prompted the withdrawal.
British police, meanwhile, are conducting their own criminal and counterterrorism investigation and have not publicly announced that the arrested suspects were acting for Iran.
RAF Fairford is critical to U.S. bomber operations
RAF Fairford is one of the most important locations supporting U.S. strategic bomber operations in Europe.
The installation does not permanently host assigned American bombers, but it contains infrastructure dedicated to supporting U.S. operations and has regularly hosted B-1Bs, B-2 Spirits, and B-52 Stratofortresses during temporary deployments.
Fairford’s location lets U.S. bombers operate much closer to Europe and the Middle East than aircraft launching from bases in the continental United States.
Its importance increased considerably during the conflict with Iran.
According to Air & Space Forces Magazine, citing open-source aircraft tracking, 29 individual American bombers had deployed through Fairford at various points during the conflict.
At the peak of the deployment, about two dozen American bombers were positioned there simultaneously—about 18 B-1Bs and six B-52Hs.
By Oct. 4, the remaining deployed force consisted of 12 B-1Bs.
All 12 left that day.
The Pentagon and European Command later confirmed that the aircraft had returned to their U.S. home stations.
B-1 remains a powerful conventional bomber
The B-1B Lancer remains an important component of America’s conventional long-range strike capability.
The four-engine bomber can carry a large payload of conventional weapons and conduct long-distance precision-strike missions.
Although the B-1 was originally developed with a nuclear mission, it was subsequently converted to a conventional-only role.
Its ability to carry substantial quantities of precision weapons makes the aircraft valuable during large-scale conventional operations.
Deploying B-1s overseas reduces the distance between the aircraft and potential operating areas.
But forward deployment also requires military commanders to protect valuable aircraft on the ground.
The Fairford episode demonstrates how quickly those calculations can change when commanders receive information indicating a potential threat to a deployed force.
In this case, the United States did not merely disperse several aircraft or move them temporarily to another European installation.
It removed the entire remaining 12-aircraft B-1 contingent from Fairford and returned the bombers to the United States.
Drone threat remains an intelligence assessment
Another distinction is essential to understanding the developing story.
British police have not publicly announced that they discovered drones during the Sept. 27 incident.
They have not announced that the seven arrested men possessed drones.
And they have not publicly stated that those suspects were preparing a drone attack against RAF Fairford.
The drone allegation comes from the two U.S. officials who described to Reuters the intelligence concern behind the American military decision.
That distinction prevents the military intelligence assessment and the British criminal investigation from being improperly presented as if they were already one proven case.
British investigators continue to examine the motivation behind the activity near Fairford.
Authorities have confirmed the arrests, suspicious vehicles, petrol recovery and absence of improvised explosive devices.
They have also acknowledged that possible foreign-state or proxy activity is among the angles being considered.
They have not publicly established Iranian responsibility.
What is confirmed
The established facts now provide a clearer picture of what happened.
Police arrested five men near RAF Fairford on Sept. 27 after receiving a report about three suspicious vehicles traveling toward the air base.
The five were arrested on suspicion of Explosives Act offenses and subsequently on suspicion of preparation of a terrorist act.
No improvised explosive devices were discovered in the vehicles, although police recovered a quantity of petrol.
Police released the five suspects on bail.
A sixth man, a 25-year-old dual UK-Iranian national, was arrested in London on Oct. 1 and subsequently released on bail.
A seventh suspect, a 22-year-old British national, was arrested in Westminster Oct. 6.
British authorities continue to investigate the incident’s motivation and circumstances.
Separately, all 12 B-1B bombers remaining at RAF Fairford departed Oct. 4 and returned to their home stations in the United States.
The Pentagon and European Command confirmed the redeployment.
Two U.S. officials told Reuters on Oct. 6 that concerns about a suspected plot involving Iran to conduct a complex drone attack against RAF Fairford led to the decision to remove the aircraft.
Iran denies involvement.
What remains unknown is whether the continuing British investigation will establish a connection between the people arrested near Fairford and the suspected Iranian drone plot described by U.S. officials.
Until investigators establish that connection, the two elements must remain carefully distinguished.
The military response, however, is no longer in question.
A threat serious enough for U.S. officials prompted the removal of all 12 B-1B Lancers deployed at one of America’s most important European bomber installations from Britain and their return to the United States.
