UK probe into Lakenheath drone reports cost nearly £608,000, but no drones were confirmed
The British investigation into suspected drone activity over three US military airbases in eastern England in November 2024 cost an estimated £607,883.87. Police logs show that some of the original sightings could not be verified as drones.
The UK Ministry of Defence has disclosed that its investigation into suspected drone activity over three US air bases in eastern England in November 2024 cost an estimated £607,883.87. The sites are RAF Lakenheath, RAF Mildenhall and RAF Feltwell, which are used mainly by the US military. Newly released documents raise questions about the reliability of some early sightings, as police at the time could not establish whether the reported objects were actually drones.
Costs and outcome of the investigation
The figure was given in a written parliamentary answer on 2 September, in reply to a question from Labour MP Graeme Downie. The probe was led by the Ministry of Defence Police. The government stressed that this is not the full financial impact: any costs from operational disruption would have to be provided by US authorities. The investigation, covering sightings between 20 and 22 November, identified no suspects, and no evidence of drone activity was presented.
Police logs
Incident logs from Norfolk and Suffolk Constabularies, obtained by independent drone researcher Ian Hudson, show uncertainty. A quadcopter reportedly seen over Lakenheath on 17 November was only reported to police on 19 November, and a search by military personnel did not find it. A 20 November entry for Lakenheath initially mentions about seven drones, but officers could not locate the objects or determine whether they were drones. A Mildenhall report refers to up to five objects circling above all three bases, but they were not independently identified. None of the logs contains independent technical confirmation.
Aircraft mistaken for drones
On 22 November 2024, a police helicopter crew assisting the search near Lakenheath reported what they believed was an approaching drone. The UK Airprox Board found it was a US Air Force F-15 fighter jet whose size and distance the crew had misjudged. There was no real risk of collision. A similar case occurred in December 2024 at Wright-Patterson Air Force Base in Ohio, where several reported objects turned out to be conventional civilian aircraft.
New incident
On 13 November 2026, US Air Force personnel responded to a new report of alleged drone activity over RAF Lakenheath. Personnel were told to shelter in place, but no people, aircraft or infrastructure were affected. Hudson says the base had asked the public to report suspected drones shortly before, which may have caused confirmation bias.
