   Incendiary Bomb is not so explosive, rather, it is a type of bomb to set fire on buildings. In order to burn out Japan cities effectively, new incendiary bomb "M-69" was developed. The effectiveness of the bomb was proved through the test in Dugway Proving Ground, Utah. In the test, a real-sized Japan style house was burned to evaluate M-69.

   M69 has three inches diameter and twenty inches length. Since 38 M-69s were combined into a cluster bomb M-19, M-69 has hexagonal cross section and has cloth tail instead of fin in order to save space. The M69 sprays napalm jerry before or after landing by five second delay fuse and TNT. Napalm is dispersed to 100ft * 100ft area, attaches buildings and clothes, and then puts fire by Magnesium.

   The first indiscriminative bombing onto residential area was examined in March 10, 1945. The Great Tokyo Air Raid killed 80,000 people in just one night. After that, other maijor cities like Nagoya, Osaka, Kobe, and so on were also attacked.

   Since June of 1945, relatively small cities like NAGAOKA had also become targets of indiscriminative incendiary bombings.
