Kamikaze (, [kamiꜜkaze]; "divine wind" or "spirit wind"), officially Tokubetsu Kōgekitai (特別攻撃隊, "Special Attack Unit"), were a part of the Japanese Special Attack Units of military aviators who initiated suicide attacks for the Empire of Japan against Allied naval vessels in the closing stages of the Pacific campaign of World War II, designed to destroy warships more effectively than possible with conventional air attacks. About 3,800 kamikaze pilots died during the war, and more than 7,000 naval personnel were killed by kamikaze attacks.
Kamikaze aircraft were essentially pilot-guided explosive missiles, purpose-built or converted from conventional aircraft. Pilots would attempt to crash their aircraft into enemy ships in what was called a "body attack" in planes laden with some combination of explosives, bombs, torpedoes and full fuel tanks. Accuracy was much better than a conventional attack, and the payload and explosion larger; about 19% of kamikaze attacks were successful. A kamikaze could sustain damage which would disable a conventional attacker and still achieve its objective. The goal of crippling or destroying large numbers of Allied ships, particularly aircraft carriers, was considered by the Empire of Japan to be a just reason for sacrificing pilots and aircraft.
These attacks, which began in October 1944, followed several critical military defeats for the Japanese. They had long since lost aerial dominance due to outdated aircraft and the loss of experienced pilots. Japan suffered from a diminishing capacity for war, and a rapidly declining industrial capacity relative to the Allies. Japan was also losing pilots faster than it could train their replacements. In combination, these factors, coupled with the unwillingness to surrender, led to the use of kamikaze tactics as Allied forces advanced towards the Japanese home islands.
