More than 500 United States military personnel have completed training in the United Kingdom since 2020, according to new figures released by the UK Ministry of Defence.
In a letter to Jeremy Corbyn, Defence Minister Alistair Carns confirmed that 501 US armed forces personnel attended UK-based training courses between 2020 and 2025, reflecting ongoing defence cooperation between the two allies.
The data shows a steady rise in participation over recent years, increasing from 54 personnel in 2020 and 56 in 2021 to a peak of 120 in 2023, before easing slightly to 105 in 2024 and 101 in 2025.
Carns said: “The Ministry of Defence offers a very broad range of International Defence Training to our partners. Information regarding the provision of training to the US Armed Forces is therefore spread across a range of sources and providers across Defence.”
US personnel have trained at some of Britain’s most prestigious military institutions, including the Royal Military Academy Sandhurst and RAF Cranwell, as well as strategic centres such as the Royal College of Defence Studies and the Joint Services Command and Staff College in Shrivenham.
Additional training has taken place across specialist schools and operational units, including the Defence Intelligence Academy, Defence Logistics School at Worthy Down, the Royal School of Artillery, and the Combined Arms Manoeuvre School in Warminster.
Several RAF bases — including Halton, Marham, Lossiemouth and Cosford — have also hosted training programmes.
The Ministry of Defence noted that the figures may not capture all training activity.
Carns stated: “Information is taken from a database of International Defence Training. Some activity may not be captured on that database.”
He added that a detailed breakdown by institution could not be disclosed, “as doing so would risk breaching data protection principles.”
The figures underline the continued strength of UK–US military cooperation, with joint training seen as a key element in maintaining operational readiness and strategic alignment between the two nations.
