In the late 1970s, Chinese designers continued the development of a next-generation main battle tank. At this stage, they already had great experience in studying Western tank building designs, including those of the U.S.A. and Germany. The 116-F3 was a reserve project that differed in its elongated hull and suspension with seven pairs of support rollers. All this provided the opportunity to further improve the engine cooling system, as well as to enhance the frontal armor and integrate alternative designs of the main armament.
