ww2dbaseThe Ki-27 Army Type 97 Fighters were the Japanese Army's first monoplane fighters, replacing the venerable biplane Ki-10 Type 95 Fighters produced by Kawasaki. Yasushi Koyama was the chief engineer behind the design. They performed superbly in the war on continental Asia, particularly at the Battle of Khalkhin Gol where Soviet fighters were helpless against the maneuverability of the Ki-27 fighters; the Soviets scored a few victories largely due to the Ki-27 aircraft's shortcomings in armor. Ki-27 aircraft were superseded by the Ki-43 design, but remained in service as bomber escorts during the opening stages of the Pacific War. Shortly after, they were slowly transferred away from the front lines, relegated to rear area patrol and training duties. Combining production numbers by Nakajima and Tachikawa, a total of 3,368 Ki-27s were built in Japan. A small number of them were built by the Manshu Aircraft Company in the Japanese-sponsored puppet state of Manchukuo in northeastern China, all of which were designated Ki-79 and were all in the configuration of trainers.
ww2dbaseThe Allied code name for the Ki-27 design was Nate.

"particularly at the Battle of Khalkhin Gol where Soviet fighters were helpless against the maneuverability of the Ki-27 fighters"
lack of combat experience and correct tactics were main reasons of Soviet defeat at early stage of Nomonhan air war. Another factor were outdated I-15bis biplanes which can't hold against superior Ki-27. I-16 type 10 could (and did) fight on par
"the Soviets scored a few victories largely due to the Ki-27 aircraft's shortcomings in armor"
Soviets depleted Ki-27 Sentais in such degree that Japanese pulled to Nomonhan about all fighters they had, including obsolete Ki-10s. Total score of Ki-27 lost in Nomonhan air combat ONLY was 66. And you name it "a few"???
