The other side – The Nakajima Ki.27

ki-27_3The air war in Malaya began on December 8, 1941. And contrary to popular belief,  the few Commonwealth fighter squadrons were not opposed by the lethal Mitsubishi A6M “Zero’s” but initially by the nimble Nakajima Ki.27 fighter.

This airplane was the winner of a 1935 competition for an advanced fighter, the specification drawn up by the Imperial Japanese Army. It was chosen because of its simple, rugged construction (air cooled engine, non-retractable landing gear, easily maintainable in the field) and its superlative manoeuvrability. Known as the Army Type 97 Fighter Model A, the Ki.27 went into production in 1937 and soon won the Japanese air-superiority in China in 1938. Nakajima built 2.020 Ki.27’s until production ended in 1942.   When the type was phased out of front line units, replaced by the Ki.43 Hayabusa (“Oscar”), it was relegated to homeland defence duties and – later – to ‘Kamikaze’ units.

According to one Japanese officer, this strip was pivotal in the early Malayan Campaign.

 “…it played a vitally important role in effecting a landing at Kota Bharu, for the Japanese Air Units could operate freely from this newly acquired base, thus accomplishing perfect protection of our convoy of transports and air cover for the landing of our troops at Singora, Patani, and Kota Bharu”.

Once the Japanese invasion forces had secured the Singora and Patani airfields, their fighters could stage through Phu Quoc and start operating in Malaya. This was quickly done and by the end of December 8, 1941, a force of 117 Ki.27 Fighters was assembled in Siam (Thailand). It consisted of

1st Sentai 42 Ki-27
11th Sentai 39 ki-27
77th Sentai 27 ki-27
4th Chutai  9 I-27

From mid December 1941 on, their offensive role would gradually be taken over by the 56 battle ready Ki-43 “Hayabusa” (Oscar) fighters of the 59th and 64th Sentais.

And although most Ki-27’s of the 77th Sentai went to fight in Burma, it left the Japanese forces with an overwhelming 9 against 1 majority in the air battles of December.

The Brewster Buffalo was certainly a match for the lightly armed and relatively slow Ki.27. But their overwhelming numbers and the battle experience of their pilots tilted the scales in their favor.

About Kingsleyr

Thank you for visiting my blog! The posts you find here are a direct result of my research into aviation and military history. I use the information I gather as a foundation and background for my books. You may call the genre historical fiction, a story woven into a background of solid and verifiable historical facts. However, the period and region I have chosen to write about (late 1930's - 1950's in South-East Asia) are jam-packed with interesting information and anecdotes. If I'd used them all I would swamp the stories. So this blog is the next best thing. It is an "overflow area" in which I can publish whatever I think will interest you. And from the reactions I get, I deduce I am on the right track. A lot will be about aviation in the former Dutch East Indies. This, because my series of books ("The Java Gold") follows a young Dutch pilot in his struggle to survive the Pacific War and its aftermath. But there's more in the world and you'll find descriptions of cities, naval operations and what not published on this blog. Something about myself; I am a Dutch-Canadian author, living in, and working out of the magical city of Amsterdam. My lifelong interest in history and aviation, especially WW2, has led me to write articles and books on these subjects. I hope you'll enjoy them!

    In reality, the Ki-27s were mostly used for airfield defence and air protection over the reinforcement convoys coming into Singora. The bulk of the damage inflicted on the RAF in northern Malaya was down to the Ki-43s of the 64th and 50th Sentai.
