The piston engines that powered Second World War fighters, the men who designed them, and the secret intelligence work carried out by both Britain and Germany would determine the outcome of the first global air war. Advanced jet engines may have been in development but every militarily significant air battle was fought by piston-engined fighters. Whoever designed the most powerful piston engines would win air superiority and with it the ability to dictate the course of the war as a whole. This is the never before told story of a high-tech race, hidden behind the closed doors of design offices and intelligence agencies, to create the war's best fighter engine. Using the fruits of extensive research in archives around the world together with the previously unpublished memoirs of fighter engine designers, author Calum E. Douglas tells the story of a desperate contest between the world's best engineers - the Secret Horsepower Race.

Proceedings of a symposium co-sponsored by the Air Force Historical Foundation and the Air Force History and Museums Program. The symposium covered relevant Air Force technologies ranging from the turbo-jet revolution of the 1930s to the stealth revolution of the 1990s. Illustrations.

Includes the Aerial Warfare In Europe During World War II illustrations pack with over 180 maps, plans, and photos. Gen Henry H. “Hap.” Arnold, US Army Air Forces (AAF) Chief of Staff during World War II, maintained diaries for his several journeys to various meetings and conferences throughout the conflict. Volume 1 introduces Hap Arnold, the setting for five of his journeys, the diaries he kept, and evaluations of those journeys and their consequences. General Arnold’s travels brought him into strategy meetings and personal conversations with virtually all leaders of Allied forces as well as many AAF troops around the world. He recorded his impressions, feelings, and expectations in his diaries. Maj Gen John W. Huston, USAF, retired, has captured the essence of Henry H. Hap Arnold—the man, the officer, the AAF chief, and his mission. Volume 2 encompasses General Arnold’s final seven journeys and the diaries he kept therein.

First ever narrative history of the famous aero engine that powered the Spitfire, Hurricane, Lancaster, Mosquito and Mustang, the aircraft that made the difference between victory and defeat at critical moments in the Second World War - the Battle of Britain and the allied aerial offensive against Germany.
