This document is a detailed historical account of the U.S. Army Air Forces' strategic air campaign against Japan during World War II. The narrative traces the evolution of the offensive from Lt. Col. James H. Doolittle's daring raid on Tokyo from an aircraft carrier to long-range bombing missions conducted with the B-29 Superfortress. It outlines how bases such as North Field on Tinian, Saipan in the Marianas, and staging facilities in Chengtu, China, were established to support operations. The text details the logistical challenges of transporting fuel and bombs over the Himalayas, known as flying "the Hump," and discusses pivotal missions including the incendiary raids on Tokyo that destroyed 17 square miles of urban area and the precision bombing of targets like the Musashino aircraft factory. It also covers the significant roles played by key personnel such as Brig. Gen. Haywood S. Hansell, Maj. Gen. Curtis LeMay, and Col. Paul W. Tibbets, Jr. in refining tactics, building up formation sizes, and ultimately employing atomic weapons that forced Japan's surrender, all of which reshaped the strategic use of air power in the Pacific theater.
