History[]
The Type 3 was developed in 1943 and it was used until 1945 despite the fact that it's production ended much earlier. It's only use was defending the Japanese Home Islands. The plane it shot down most were American B-29 Superfortresses and in Tokyo, the Type 3 was recoreded shooting down at least ten. However, when the bombers came in large numbers, the Type 3's effectiveness decreased. Only 120 Type 3's were made by World War II's end mainly because metal was scarce.
