killing one American soldier will do. ... You must aim for the abdomen." They were expected to serve as a "second defense line" during the Allied invasion, and to conduct guerrilla warfare in urban areas and mountains. The Japanese command intended to organize its Army personnel according to the following plan: Total mobilized: 3,150,000 Kyushu – 900,000 Kanto (Tokyo) – 950,000 Korea – 247,000 For the Decisive Battle Kyushu – 990,000 Kanto – 1,280,000 Allied re-evaluation of Operation Olympic Air threat US military intelligence initially estimated the number of Japanese aircraft to be around 2,500. The Okinawa experience was bad for the US—almost two fatalities and a similar number wounded per sortie—and Kyūshū was likely to be worse. To attack the ships off Okinawa, Japanese planes had to fly long distances over open water; to attack the ships off Kyūshū, they could fly overland and then short distances out to the landing fleets. Gradually, intelligence learned that the Japanese were devoting all their aircraft to the kamikaze mission and taking effective measures to conserve them until the battle. An Army estimate in May was 3,391 planes; in June, 4,862; in August, 5,911. A July Navy estimate, abandoning any distinction between training and combat aircraft, was 8,750; in August, 10,290. By the time the war ended, the Japanese actually possessed some 12,700 aircraft in the Home Islands, roughly half kamikazes. Ketsu plans for Kyushu envisioned committing nearly 9,000 aircraft according to the following sequence: 140 reconnaissance planes to detect the approach of the Allied fleet. 50 "land attack planes," 50 seaplane bombers, and 50 torpedo bombers flown by highly trained pilots for night attacks on convoy escorts. 825 Navy kamikazes to attack the landing convoys prior to their arrival off Kyūshū. 2,500 Army aircraft (conventional as well as suicide), together with 2,900 Naval trainers for kamikaze attacks against the landing fleet as it arrived and anchored (5,400 total). 2,000 Army and Navy "air superiority" fighters to escort the kamikazes and strafe landing ships. 330 Navy bombers flown by highly trained pilots to attack the Allied carrier task force to prevent it from supporting the invasion convoys. 100 transport planes carrying 1,200 commandos for a raid on the US airbases on Okinawa, following the success of earlier smaller-scale operations. The Japanese planned to commit the majority of their air forces to action within 10 days after the Allied fleet's arrival off Kyūshū.
