Japanese kamikaze pilots were formed in response to Japan losing momentum in WWII. Vice Admiral Takijiro Onishi decided to form a suicide attack unit called the Kamikaze Special Attack Force. Kamikaze pilots willingly crashed their explosive-laden planes into enemy ships, causing extreme damage. By the end of the war, kamikaze pilots had sunk 34 US ships and damaged 288 ships, accounting for up to 80% of US losses late in the war in the Pacific.
