The Type 88 75 mm AA gun (八八式七糎野戦高射砲, Hachi-hachi-shiki nana-senti Yasen Koshahō) was an anti-aircraft gun used by the Imperial Japanese Army during the Second Sino-Japanese War and World War II. The Type 88 number was designated for the year the gun was accepted, 2588 in the Japanese imperial year calendar, or 1928 in the Gregorian calendar.^[3] It replaced the earlier Type 11 75 mm AA gun in front line combat service, and at the time was equal in performances to any of its contemporaries in Western armies^[4] and was considered capable of handling any targets the Japanese army was likely to encounter on the Asian mainland. Although it was soon overtaken by improvements in aircraft technology and was largely obsolete by 1941, it continued to be used on many fronts until the end of the war.
