Dubbed the 'Oscar' by the Allies, the Ki-43 Hayabusa Peregrine was the most prolific Japanese fighter of World War 2. Designed for manoeuverability and speed, the low-wing model meant that firepower and safety had to be sacrificed, with only two machine guns per plane. Despite this, more Japanese pilots achieved Ace status flying the Hayabusa than any other plane. This book expertly charts the experiences of the pilots and discusses the early stages of the war in South-East Asia, China, Burma and New Guinea. Accompanied by detailed appendices and specially commissioned artwork, this is the first volume in English to focus exclusively on the exploits of the Ki-43.
