Nakajima Ki-27 (Nate) Type 97
Initially conceived of as a private venture design by Nakajima corporation, the Ki-27 debuted and was accepted by the Japanese Army and entered service in 1937. The fighter was very maneuverable and fast, but lacked self-sealing fuel tanks, pilot protection and had only two 7.7mm machine guns.
Nicknamed 'Nate' or 'Abdul' by the Allies. In the early years, the Ki-27 enjoyed a period of success against the Chinese and Allied fighter pilots in the early Pacific war. As Allied fighter designed continued to improve, aircraft like the Ki-27 was relegated to second line duty, training or kamikaze use. Also, the Mansyu Ki-79 trainer version built by Manshūkoku Hikōki Seizo KK, in four sub-versions.
