Type 5 is the biggest AA gun that the Japanese has developed. Two guns of Type 5 were deployed at Kugayama in the suburbs of Tokyo in August, 1945, just before the end of WWII. They brought down two B-29s by the first engagement. However, they had no chance to fire after that, because B-29 avoided to fly over Kugayama.
