Ōka K1 Trainer Version
National Museum of the U.S. Air Force
Wright-Patterson Air Force Base, Ohio
The National Museum of the U.S. Air Force is the largest military aviation
museum in the world with over 360 aerospace vehicles and missiles on display.
The museum has a few exhibits related to Japan's Kamikaze Special Attack Corps
that made attacks on Allied ships from October 1944 to August 1945.
The Ōka Type 11 was a rocket-powered glider used for suicide attacks on American ships at the end of
the Pacific War from March to June 1945. A Type 1 Attack Bomber (Allied code
name of Betty) served as the mother plane that carried the ōka weapon suspended underneath and then released it when a point was reached near
the intended target. The ōka could reach a speed of 600 mph as it accelerated toward its target
with three rocket engines mounted in its tail. The National Museum of the U.S.
Air Force has an orange-colored K1 trainer version of the ōka on display. The trainer differed from the Type 11 by the addition of a
landing skid and flaps, and water was used as ballast equal in weight to the
1.3-ton warhead carried in the Ōka Type 11's
The museum has on exhibit a restored Zero carrier-based fighter (Allied code
name of Zeke) that was found in Papua, New Guinea. The Zero fighter was the most
frequently used aircraft used by the Kamikaze Special Attack Corps. About 50% of
the Japanese Navy's 2,363 aircraft that took off on kamikaze flights were Zero
fighters, and 530 of the 1,189 Navy planes that completed their suicide missions
were Zeros (Okumiya and Horikoshi 2004, 353).
The Grumman F6F Hellcat and the Vought F4U Corsair fighters were the primary
American aircraft used to combat Japanese kamikaze planes.
Republic P-47 Thunderbolt fighters were also used against the kamikaze aircraft
in May and June 1945 during the Battle of Okinawa. The National Museum of the
U.S. Air Force has on display two P-47 Thunderbolts, a razorback version and a
bubble canopy version.
