The Desperate Tactic of Kamikaze

TL;DR

Japan developed suicide attacks across air, sea, and underwater because conventional forces could no longer stop the advancing Allies.

Key Points

• 1.Shinyo explosive speedboats were the most effective maritime kamikaze method — 6,200 were built using Toyota car engines, wooden hulls, and 595 lb bow charges capable of 23 knots
• 2.Kaiten human torpedoes were modified Type 93 Long Lance torpedoes carrying a 3,420 lb warhead, launched from submarines; only 330 were produced and their first confirmed kill was the USS Mississinewa in November 1944
• 3.Fukuryu "Crouching Dragon" frogmen were suicide divers planned to wait in underwater concrete shelters armed with pole-mounted mines; Japan planned 40,000 of them but the program was abandoned before deployment
• 4.Kamikaze pilots received minimal training — they were taught to take off and dive, but not land; crews were recruited from men aged 16–20, and while technically volunteers, many faced social and command pressure
• 5.Three defensive rings protected American fleets: outer combat air patrols, middle radar-equipped picket destroyers, and inner cruisers/carriers — making kamikaze breakthroughs increasingly rare as the war progressed
• 6.Nearly 4,000 kamikaze pilots died in the final months of the war, killing thousands of Americans, with Okinawa becoming the deadliest naval battle in US history — yet the attacks could not reverse Japan's defeat
