The Kayaba Ku-2 (萱場 2型無尾翼滑空機) was a glider built in Japan in 1940 to investigate the possibilities of tailless aircraft.[1] It was developed as part of an Imperial Japanese Army contract that had been offered to designer Hidemasa Kimura following the successful flights of his HK-1 tailless glider over the previous years.
