Surrounded by exhibits at the Steven F. Udvar-Hazy Center, NASM. The Kikka resembled the Me-262, although it was smaller and had straight wings. It was powered by Kugisho Ne-20 turbojets that were developed from notes of an officer who survived the submarine voyage from Germany to Japan. The prototype Kikka was flown by Lt. Cdr. Susumu Takaoka from Kisarazu Naval Air Base on Aug. 7, 1945, days before Japan surrendered.
