Kamikaze attacks — known as "special attacks" by Japan — were an infamous tactic designed to not only destroy American ships but also strike fear in the Allied navies.
But two months before the first kamikaze attacks were carried out at the Battle of Leyte Gulf in Oct. 1944, a Japanese transport pilot pitched the idea of a kamikaze super weapon, the Oka "Cherry Blossom" Type 11 plane.
The pilot would be left sitting in the cockpit, piloting his coffin into the ocean with no chance at destroying a target.
In the end, the more than 850 Oka 11s produced sank only one ship and damaged six others. Longer range variants were produced that could fly up to 81 miles. They would have been a serious threat to Navy ships during an invasion, but none ever saw combat.
