The HQ-22 is a new China's air defense missile system. It was first revealed in 2014 in a downgraded form and was known as the FK-3. The FK-3 was mainly aimed at export customers. The HQ-22 can be seen as an improved and more mature version of the FK-3. It was first publicly revealed in 2016. By 2019 the HQ-22 was already in operational service. So far it is one of the most capable China's air defense missile systems. It replaces in service the ageing HQ-2 air defense systems.
