When the revolutionary twin jet-powered Arado Ar 234 first appeared in the skies over north-west Europe in the summer of 1944, it represented the state-of-the-art in terms of aeronautical and technical development. The Ar 234 was a formidable aircraft – powered by Jumo 004Bs, the same engine used by the Me 262, and with a maximum speed of 735 km/h and range of 1600 km/h, it was very difficult for the Allies to ‘catch’. Here was a machine that with its superior speed could operate with impunity as both a bomber and in the reconnaissance role. This highly detailed title explores the history of this incredible aircraft, from its development in the early 1940s to its deployment in both reconnaissance and bomber roles throughout the rest of the war. Illustrated throughout.
