American military aviation made an outstanding contribution to the victory of the allies in the anti-Hitler coalition in World War II. Thousands of American aircraft delivered to the USSR left a good memory among the Soviet aviators who fought on them against the common enemy. The book, prepared on the basis of archival materials, describes almost all US aircraft and their modifications that took part in World War II. The text is complemented by documentary paint schemes for American aces and detailed three-dimensional diagrams of the most famous aircraft.
