Manchukuo Imperial Air Force

The Manchukuo Imperial Air Force (Chinese: 飛行隊; pinyin: Fēixíng Duì; Japanese: 大満州帝国空軍, romanized: Dai Manshū Teikoku Kūgun) was the air force of Manchukuo, a puppet state of Imperial Japan. The air force's predecessor was the Manchukuo Air Transport Company (later renamed the Manchukuo National Airways), a paramilitary airline formed in 1931, which undertook transport and reconnaissance missions for the Japanese military.
