HN-5C

A vehicle-mounted version of HN-5B that first entered production in 1986, but was not revealed to public in China until early 1990s. A total of eight missiles are configured into two groups of four missiles mounted on a 4x4 vehicle with an electro-optical fire control system. The size of the vehicle determined whether reloads could be used. Although the missiles of the vehicle-mounted version can be used as MANPADs, they can not be used as such in the field, they need to be retrofitted first.

HQ-5C

HQ stands for Hong Qi, or Red Flag, the common Chinese designation for their surface-to-air missiles. The missile was specifically developed in the 1980s for export, and it is an Westernized HN-5B by adopting western standards. The reason was because despite its low price, when the Soviet style HN-5 had been exported to third world countries mainly armed with western weaponry, the compatibility issues and associated logistical problems increased the overall life cycle cost of the missile. To avert this, the missile is modified to be compatible with western standards. Philippines reportedly was the customer of HQ-5C, and Thailand was rumored to be the other customer of HQ-5C
