The Nakajima Ki-43 Hayabusa (隼, "Peregrine falcon"), formal Japanese designation Army Type 1 Fighter (一式戦闘機, Ichi-shiki sentōki) is a single-engine land-based tactical fighter used by the Imperial Japanese Army Air Service in World War II.

Often mistaken for Mitsubishi’s A6M Zero, the Hayabusa (reporting name Oscar) was the Imperial Japanese Army Air Service’s primary land-based fighter during WWII. Sometimes called the “Army Zero” by American Pilots, the Hayabusa had generally similar lines to its more well known Imperial Japanese Navy cousin.

The Nakajima Ki-27 (九七式戦闘機, Kyūnana-shiki sentōki, Type 97 Fighter) was the main fighter aircraft used by the Imperial Japanese Army Air Service up until 1940.

Assigned letters included 甲 (Ko) for Nieuport, 乙 (Otsu) for Salmson, 丙 (Hei) for SPAD, 丁 (Tei) for Farman, 戊 (Bo) for Caudron, and 己 (Ki) for Hanriot. The "Ki" (キ; abbreviation of kitai = airframe) designation was also used and became prominent in later years.

May 10, 2016 · At the time of its inception, the Ki-27 became the first Japanese monoplane to achieve operational service with the military. While fighting on until the end of the war in 1945, Nates were quickly withdrawn from direct contact against the more modern Western fighters as they were wholly outclassed.

Aug 1, 2015 · Several publications on the Nakajima Ki 43-1 (or Oscar Mark 1) state that this aircraft came in three sub-types, which differed in their armament. These were the types ko, otsu, and hei, the Ki 43-IA (2x7.7mm), Ki. 43-IB (1x7.7mm and 1x12.7mm), and Ki 43-IC (2x12.7mm).

The Nakajima Ki-43 Hayabusa, or ‘Oscar,’ was a symbol of Japan’s innovative approach to World War II fighter aircraft. Its agility and speed set it apart, challenging Allied pilots across the Pacific. But what drove its design, and how did it fare in the heat of battle?

キ47 は、 大日本帝国陸軍 が計画した軽 爆撃機。 実機の製造には至らずに終わっている。 1937年 （昭和 12年）、陸軍は 九三式双発軽爆撃機 の後継機となる新たな 航空撃滅戦 用の軽爆撃機の開発を計画した。 これを受けて、 三菱重工業 に対して計画名称「キ47」の試作発注が予定されていたが、発注されることなく終わった。 なお、同時に計画されたキ48は実際に 川崎航空機 に発注され、のちに 九九式双発軽爆撃機 となっている。 予定されていた乗員数は、九 …

Mar 28, 2007 · It was a slow, fragile and lightly armed, but an extraordinarily maneuverable, fast climbing plane of fame. Although it was very vulnerable in battle, most who flew it would agree it was a beautiful airplane to handle. Production started in 1941 and continued until 1944, with 5,751 aircraft produced.

As with the Japanese Navy’s A6M Zero fighter the Army’s Ki-43 Hayabusa or Peregrine Falcon came as a shock to American and British pilots when war broke out in the Pacific in 1941. The low wing, all metal monoplane fighter was more maneuverable and faster than most of the fighters available to the Allies at the beginning of the war.
