Only 40 Nakajima Ki-43 fighters (Allied code name Oscar) had been deployed to the Malay Peninsula. at the start of WW II. They were assigned to escort duties for bombers on missions over Hong Kong and Burma.

Nakajima Ki-43 aircraft were a match for early World War II Allied fighters.

The Japanese Navy Zero is better known than the Nakajima Ki-43, while being only slightly faster. In fact, the Ki-43 could out turn and had a better initial climb rate than the Zero.

Initial shortcomings of the Nakajima Ki-43 were its lack of armor protection for the pilot and fuel tanks, plus the aircraft being equipped with only two 12.7 mm machine guns. Later models had a more powerful engine, armor, and self sealing fuel tanks. One version was even produced with clipped wings.

Eventually over 5,900 Nakajima Ki-43 Oscars of all types were built. They were the most numerous fighters used by the Japanese Army during World War II. Only the Japanese Zero, used by their navy, was produced in greater numbers.
