Officially announced in 2010, the Type 10 is the fourth generation main battle tank serving the Japan Ground Self Defense Force (JGSDF). It is equipped with a domestically-developed smoothbore 120mm main gun and automatic targeting system that allows tracking of targets while the highly mobile Type 10 is on the move. Modular armor on the turret and hull not only provides top level protection, it can also be removed to allow swift transportation across the Japanese archipelago on trailers and the like. Delivery to units commenced in 2012 and the Type 10 is envisaged to replace the long-serving Type 74.
