The development of the B-29 gave the United States a bomber with sufficient range to reach the Japanese home islands from the safety of American bases in the Pacific or western China. The capture of the Japanese island of Iwo Jima further enhanced the capabilities that the Americans possessed in their strategic bombing campaign. High-explosive and incendiary bombs were used against Japan to devastating effect, with greater indiscriminate loss of life in the firebombing of Tokyo on March 9/10, 1945 than was caused either by the Dresden mission, or the atomic bombs dropped on Hiroshima or Nagasaki. Unlike the USAAF's strategic bombing campaign in Europe, with its avowed (if unachievable) objective of precision bombing of strategic targets, the bombing of Japanese cities involved the deliberate targeting of residential zones from the outset. Bomb loads included very high proportions of incendiaries, with the intention of igniting the highly combustible wooden houses common in Japanese cities and thereby generating firestorms.
