The {{nihongo|'''Nakajima Ki-11'''|キ11 (航空機) |Ki-jyuichi Kokūki}} was an unsuccessful attempt by [[Nakajima Aircraft Company]] to meet a 1935 requirement issued by the Japanese government for a modern single-seat [[monoplane]] [[Fighter aircraft|fighter]] suitable to meet the needs of both the [[Imperial Japanese Army Air Force]] and [[Imperial Japanese Navy Air Service]]

==Design and development==
Development of the Ki-11 began as a private venture in 1934, based on a [[Flying wires|wire]]-braced low-wing monoplane, inspired by the [[Boeing P-26 Peashooter]]. The [[fuselage]] wing center section and [[Landing gear|undercarriage]] were constructed in [[duralumin]], while the wings and tail were of wood and canvas. The aircraft was powered by a single {{convert|410|kW|hp|-1|abbr=on}} [[Nakajima Kotobuki]] Ha-1-3 [[radial engine]]. Proposed armament consisted of twin 7.7&nbsp;mm (.303&nbsp;in) [[machine gun]]s firing from between the engine cylinders.<ref>{{Harvnb|Wieliczko|Prusza|2004|pp=9–10.}}</ref>

The Ki-11 was entered into competition with the [[Kawasaki Ki-10]] [[biplane]] design. Although technically more advanced and faster than the [[Kawasaki Heavy Industries Aerospace Company|Kawasaki]] design, the [[Imperial Japanese Army]] command was split between supporters of "maneuverability" and supporters of "speed". The supporters of the "maneuverability" scheme won, and the Ki-10 became the main army fighter until 1937.<ref>{{Harvnb|Wieliczko|Prusza|2004|pp=10–11.}}</ref> Nakajima continued to refine the Ki-11 design, and it re-emerged in the form of the [[Nakajima Ki-27]] "Nate" several years later.<ref>{{Harvnb|Mikesh|Abe|1990|p=218.}}</ref>

Nakajima later sold the fourth prototype as '''AN-1 Communications Aircraft''' to the ''[[Asahi Shimbun]]'' newspaper, who registered it as '''J-BBHA''' and used it as a [[Liaison aircraft|liaison]] and courier plane, and for [[reconnaissance]] and news-gathering flights.<ref>{{Harvnb|Mikesh|Abe|1990|p=219.}}</ref>
