The upgraded version of the 121 Chinese medium tank, developed in the 1960s. Unlike the prototype, the 121B was equipped with a modern 105-mm rifled gun, improved suspension, and reinforced front armor. The vehicles of this modification were equipped with infrared lamps and a laser rangefinder. The 121B aiming system had a higher firing accuracy than that of the Type 59.
