The gun was based on the German 2 cm Flak 30/38/Flakvierling.Taki’s Imperial Japanese Army: "AA Weapons" It was driven by electric motors, obtaining its power from a generator trailer. The Type 2 number was designated for the year the gun was accepted, 2602 in the Japanese imperial year calendar, or 1942 in the Gregorian calendar.War Department TM-E-30-480 Handbook on Japanese Military Forces, September 1944, p. 400.
