Type 75 155 mm self-propelled howitzer

The Type 75 was a 155 mm self-propelled howitzer built for the Japan Ground Self-Defense Force, adopted in October 1975 and entering service that year alongside the Type 74 105 mm self-propelled howitzer, with which it shared automotive components. Mitsubishi Heavy Industries built the chassis and Japan Steel Works developed the turret and gun. A crew of six operated the vehicle, whose hull and turret were protected by heat-treated aluminium alloy armour, and its 155 mm L/30 gun was loaded automatically from two nine-round drum magazines while the propelling charges were loaded by hand. Power came from a Mitsubishi 6ZF21WT two-stroke V6 turbocharged diesel engine of 450 horsepower. Procurement ran from 1977 to 1985 and 201 were built, most of them posted to Northern Army units in Hokkaido. The Type 99 replaced it, and the last were retired by March 2014.
