Barbarossa was the biggest German invasion of World War II. Comprehensively illustrated, this study explores the air campaign that spearheaded it, and how it evolved during the rest of 1941. The German invasion of the USSR, Operation Barbarossa, was the apex of Hitler's aggression. The strength of the Luftwaffe was gathered from across Europe for its opening strikes, where it faced a huge but badly equipped and ill-prepared Soviet Air Force (VVS) of 20,000 aircraft, which it quickly destroyed. In this book, Eastern Front expert William E. Hiestand examines this shattering first campaign, as well as how the Barbarossa air war developed over the following months. He describes how between June and December 1941, Luftwaffe losses rose and aircraft readiness steadily decreased under the pressure of combat. He also analyses the evacuation of Soviet industry – including aircraft production – to the Urals, and the rebuilding of the VVS; by the time German columns stalled 25km from Moscow, the VVS had more operational aircraft at the front than the Luftwaffe. He also covers aspects such as the abortive VVS strikes on Berlin and other strategic targets, and the Luftwaffe's strategic bombing raids on Moscow. With striking original artwork, 3D diagrams, maps and rare photos, this book reveals the full story of the aerial campaign in Barbarossa, as the devastation began in the most brutal theatre of World War II.
