The Type 11 75 mm AA Gun (十一年式七糎半野戦高射砲 Jyūichinen-shiki nana-senti-han Yasen Koshahō) was an anti-aircraft gun used by the Imperial Japanese Army after World War I. It was the first anti-aircraft gun in Japanese service, but only a small number were produced, and it was superseded by the Type 14 10 cm AA Gun and the Type 88 75 mm AA Gun in active service before the start of World War II.
History and development
Due to combat experience at the Battle of Tsingtao against the Imperial German Luftstreitkräfte’s fledgling squadron of combat aircraft, planners on the Imperial Japanese Army General Staff quickly realized that this new technology posed a threat which required countermeasures. This evaluation was further reinforced by reports from military observers on the European front in World War I.
The Type 11 75 mm AA Gun was placed into production in 1922, taking design features from a number of overseas design, including the British Vickers QF 3 inch 20 cwt AA gun [1] However, it was expensive to produce and lacked both accuracy and range of fire. Only 44 units were completed before production was terminated. [2]
Design
The Type 11 75 mm AA gun had a single piece Gun barrel with sliding breech, mounted on a central pedestal. The firing platform was supported by five legs, each of which (along with the central pedestal) had adjustable screwed foot for leveling. It fired a 6.5 kilogram projectile to an effective altitude of 6,650 meters. [3]
Combat record
The Type 11 75 mm AA gun saw limited service with Japanese combat forces during the invasion of Manchuria, Soviet-Japanese Border Wars and the Second Sino-Japanese War. It was withdrawn from active service prior to the start of the Pacific War. [4]
