UK-British Nuclear Test Chart

UK and Australian Atmospheric Nuclear Tests

Can offer this info only in reference to the Air Force, but AF SAC units spent 3 month rotational duties to England (Upper Heyford, Lakenheath, Mildenhall, Marham, Sculthorpe and Wyton), attached to the RAF, during the period of the British Nuclear test development. Maybe some vets from other service branches can shed light on presence at UK tests.
