When the revolutionary Messerschmitt Me 262 jet first appeared as a bomber in the skies over north-west Europe in late 1944, it represented both a new dawn in aeronautical development and a great shock to the Allied air forces and armies. In mid-1944, Adolf Hitler, having seen the impressive and formidable performance of Me 262 prototypes, stated his firm desire to see the aircraft enter service as a bomber. There was nothing which the Allies had in their air forces which could touch the Me 262. Although, due mainly to problems associated with delays in engine deliveries, its debut was too late to contest the Allied landings in Normandy, when it finally did enter initial service in the autumn of 1944, the bomb-carrying Me 262s conducted several hit-and-run raids against RAF airfields in Belgium and Holland. From then until the end of the war the Me 262 remained one of the most feared weapons in the Axis arsenal. This book covers the complete history of the Me 262 bomber and reconnaissance units during World War II.
