Portable anti-aircraft missile system HongYing 6 (FN-6)

The main element of the FN-6 man-portable air defence system is an anti-aircraft guided missile (SAM) located in a fibreglass transport and launch container (see photo). The SAM consists of a hull, infrared homing head (HID), electronic control equipment, fuse, fragmentation warhead, marching and dropping launch engines. The missile is designed according to the aerodynamic scheme of the "duck" and has four stabilizers in the tail and four rudder in the front, which provides it with high maneuverability, allowing it to hit a target that performs maneuvering with an overload of up to 4g with a probability of at least 0.7.

The infrared homing head (HID) with four cells is placed inside a pyramidal fairing. Such its form has advantage over usual spherical (typical for the previous models of man-portable air defense systems of Chinese manufacture), as essentially reduces frontal resistance. To achieve high sensitivity, deep cooling of the receiver is applied (the refrigerant tank is attached to the trigger from below). It is assumed that the CLO is capable of guiding the missile when the interference is active in the infrared range.

Man-portable air defense systems can be equipped with a telescope sight and identification equipment "in-situ". The sight and the requester are mounted in the head part of the complex.

As well as previous versions of man-portable air defence systems, this system can be installed on tracked vehicles, helicopters and ships. The ship version of the FN-6 complex has a stabilized remote-controlled launcher with four missiles.
