Type 87 self-propelled anti-aircraft gun

The Type 87 is a Japanese self-propelled anti-aircraft gun of the Japan Ground Self-Defense Force, built around the Oerlikon 35 mm twin cannon system also used on the German Gepard. It uses a modified Type 74 tank chassis built by Mitsubishi Heavy Industries, carrying a turret and licence-produced guns from Japan Steel Works. Development began in 1976, a prototype on the Type 61 chassis proved too heavy, and work moved to the Type 74 chassis in 1982, with the vehicle accepted into service in 1987. Its two 35 mm autocannons fire 550 rounds a minute each, the search radar sits at the rear of the turret and the fire control radar on top of it, and a Mitsubishi 10ZF22WT two-stroke V10 diesel powers the chassis. Procurement ended in 2002 after 52 had been built, and about 50 were still in service in 2024. Field officers nicknamed it Guntank.
