Photograph of the delivery of first 'Thor' Ballistic Missile to an RAF Base in Norfolk, 19th September 1958. Sixty-five feet long, it was carried to the site from a nearby American base on a 90 foot long transporter. The 'Thor's' nuclear war-head was retained by the Americans and any British decision to launch this missile would have been subject to American approval. RAF Regiment guards can be seen in the foreground, ready to deter any naughty ideas.
