The development of anti-tank missiles in China began in the late 1950s and early 1960s. At that time, the alliance between China and the big brother of the world socialist countries-the Soviet Union took a sharp turn for the worse. Overnight, the Soviet Union not only withdrew all kinds of experts who helped China, but also tore up all kinds of cooperation agreements signed with us. As a result, on the originally calm Sino-Soviet border, thousands of kilometers, both sides are eyeing up, and the Soviet Union is facing a million soldiers, as if a national war is on the verge! However, what our leaders are most worried about is not the Soviet nuclear weapons or their new missiles, but the Soviet world-class flood of steel and armor-all kinds of tanks and armored vehicles. At that time, China faced great threat from Soviet armored assault cluster in Inner Mongolia grassland and Sanjiang Plain, especially in Inner Mongolia grassland. Soviet armored cluster can attack China's strategic heart, the capital, without hindrance. Therefore, the Central Military Commission put forward the slogan of "three strikes and three defenses", the first of which is to fight tanks. It can be seen that how to attack the Soviet Union's fast armored assault group became the primary task of our army at that time. Especially after the Sino-Soviet armed conflict at the beginning of 1968, the demand for anti-tank weapons by China's frontline troops became more urgent. In addition to vigorously developing all kinds of flat-fire anti-tank guns and their ammunition, China has followed the world trend and started to develop its own first-generation anti-tank missiles.
