HN-6
HN-6 is a further development of FN/FY-6/16. The Chinese name for this missile is actually Hong Ying (红樱), meaning Red Tassel. However, HY, the Pinyin abbreviation of Hong Ying was already taken by the name of another Chinese missile family, the Silkworm series anti-shipping missile, whose Chinese name is Hai Ying (海鹰), meaning Sea Eagle. As a result, the designation of this follow-on of FN-6 MANPADS is changed to HN-6 to avoid confusion, following the earlier MANPADS HN-5. HN-6 utilizes fire control systems (FCS) of earlier FN/FY-6/16 MANPADS, but a new FCS sight of unknown designation has also been developed and publicized by Chinese state media.
In addition to improved performance over the original FN/FY-6/16 MANPADS, HN-6 incorporates a protective cap over the seeker of missile, offering better protection against the environmental elements. Based on the photos and video clips of PLA training, this protective cap does not appear to be automatically ejected when the missile is fired, but instead, it is manually removed before firing the missile. Another improvement of HN-6 over the earlier FN/FY-6/16 MANPADS is that it incorporates a fire station similar to that of RBS 70 and Mistral: a seat is attached to the light weight tripod firing stand that can be folded for transportation and storage, and the operator is protected by a bulletproof glass shield.
