World War II in the Pacific
Japanese Suicide Attacks at Sea.

---

It is not uncommon in warfare for a wounded soldier to "Take one with him." The most dramatic is that of a pilot on either side with a damaged plane, with no hope of getting home, to ram the enemy, either in the air, on the ground, or at sea.

14 October44. Japanese aerial counterattacks continue on TF 38, inflicting damage on light cruiser Reno (CL-96) by a suicide plane.

Late in the war, the Japanese established a policy of intentional suicide, called "special attack".  From 23 October 1944, the policy of suicide attack inflicted much damage on the US fleet.

Kamikaze -- Japanese Navy suicide plane. The Army also used suicide planes.

• 21 Oct44  Two planes with volunteers flew from the Philippines to attack U.S. carriers and crashed HMAS Australia.
• 25-26 Oct44.  Off Leyte, 55 Kamikaze pilots, in the first planned mass suicide attacks of the war, coordinated with the IJN attack in Leyte Gulf, hit the escort carriers and sank St. Lo (CVE-63) and damaged the large escort carriers Sangamon (CVE-26), Suwannee (CVE-27), Santee (CVE-29), and small escort carriers White Plains, Kalinin Bay, and Kitkun Bay.   In all, 7 carriers were hit and 40 other types damaged; five ships were sunk, 23 heavily damaged, and 12 moderate damage.
• 25Mar45-21Jun45. Off Okinawa -- Ten "Kikusui", swarms of Kamikaze, up to 350 attackers at a time, 1,900 in total, damaged 250 ships with 34 destroyers and smaller ships sunk.  Several ships were damaged so badly they were not repaired. One in seven of all naval causalities occurred off Okinawa.
• 3,500 naval planes and an additional 1,500 army planes are hidden on Kyushu for the "final battle" and just as many for orthodox use ; once suicide planes were used up, the orthodox pilots would become Kamikazes. This is a number sufficient to sink or damage 1,000 ships of an invading fleet.

Mitsubishi J8M/Ki-200 Shusui -- rocket powered interceptor.

Nakajima Ki-115.  -- Specially built, basic aircraft that could carry a bomb for kamikaze attacks.

Shinten Special Unit 47th Air Regiment -- to defend the Tokyo Metropolitan Area.

Reppu.  -- Specially designed kamikaze for use against B-29 ;  the war ended before production.

Yokosuka Ohka. --   A piloted glide bomb, called "BAKA" (idiot) by the allies.

• 21Mar45. Japanese make first known operational use of Baka piloted bombs in unsuccessful air attack against TF-58.
• 12Apr45. Off Okinawa, destroyer Mannert L. Abele (DD-733) is sunk by Baka -- she is the first U.S. Navy ship to be sunk by that type of weapon.  Destroyer Stanly (DD-478) is damaged by Baka.  High speed minesweeper Jeffers (DMS-27) is damaged by Baka and kamikaze.
• 4 May45. Light minelayer Shea (DM-30) is damaged by a Baka.  Minesweeper Gayety (AM-239) is damaged by near-misses of kamikaze and Baka.
• 10May45 -- In a crash program to counter the Japanese Baka (suicide) bomb, the Navy authorized development of Little Joe, a ship-to-air guided missile powered with a standard JATO unit.
• 11May45. Destroyer Hugh W. Hadley (DD-774) is damaged by Baka.

Ki-167 or Hiryu To-Go --   Bomber with 3 ton thermite bomb.

Nikaku -- Human anti-tank mine - Soldiers with explosives strapped to their bodies.
