FN-6A

FN-6A is the vehicle-mounted version of FN-6 first revealed to the public in 2005. The system is based on a Dongfeng EQ2050, weighing 4.6 tons in total. A one-man turret is sandwiched between two quadruple launchers, and the electro-optical fire control system (FCS) with IR, laser, and TV sensors. Contrary to the common arrangements on similar systems, the FCS of FN-6A is mounted under the launchers. Due to space limitations, the FCS is distributed between two places, one portion under one launcher and the other portion in the opposite launcher across the turret. A 12.7 mm heavy machine gun is added for additional protection. The vehicle is operated by a two-man crew, one driver, and one weapon system operator. Communication gear and land navigation gear are standard. The modular design of the system enables other subsystems to be incorporated easily, such as IFF. The auxiliary power unit provides enough power for the system to operate continuously for more than 8 hours.

The FCS of the FN-6A can lock on to a target 10 km away, and the reaction time is less than 5 seconds. Each vehicle can fight independently but can be integrated with others to fight as a coherent unit by incorporating a command vehicle that is also based on the same vehicle chassis. The command vehicle provides a light solid-state passive phased array radar to increase situational awareness and can direct up to 8 launching vehicles simultaneously. A command vehicle and 8 launching vehicles form an air defense company when fighting as a coherent unit, and this in turn can be integrated into larger air defense networks. Alternatively, the launching vehicle can be directly integrated into larger air defense networks without the need for the command vehicle.

Each launching vehicle needs a support vehicle for resupply, and the support vehicle is also based on Dongfeng EQ2050 to reduce logistic costs. Each supply vehicle carries 24 missiles and reloading each missile takes less than a minute. Similar to the M1097 Avenger, each launcher is designed so that each missile can also be removed and fired by a soldier manually like a regular MANPAD. Although effective against supersonic aircraft, for UAVs and missiles the maximum target speed is limited to 300 meters per second.

FB-6A

FN-6A did not enter mass production and served only in very limited numbers in Chinese forces, mainly for trial purposes. In the subsequent Zhuhai Airshows followed by its original debut, FN-6A is replaced by its successor FB-6A, which did see greater numbers in service with Chinese forces. The general designer of the FB-6A system is Mr. Wei Zhigang (卫志刚), rumored also to be the general designer of FN-6A, the predecessor of FB-6A.^[6] The main difference between FN-6A and its successor FB-6A is that the SAM system is broken down into two portions in the latter, as opposed to a single unit in the former: FB-6A SAM system consists of two vehicles, one carrying the engagement radar, while the other carrying the missile.^[7][8] The search/engagement radar of FB-6A is planar array, and can be folded down in transit, but the developer has not revealed whether the radar itself is a phased array or not.^[9] However, the developer did claim that both the mechanically scanned planar array and the electronically scanned passive phased array are both available upon customer's request, but it's not clear which one is in service with Chinese forces.

The missile launching platform of FB-6A differs from its predecessor in that both the 12.7 mm heavy machine (HMG) for self-protection and the electro-optical fire control sight on that of FN-6A are removed, but a backup operator console is incorporated with bulletproof glass added between the launchers, though the FB-6A system can be operated with the vehicle. Although the 12.7 mm HMG no longer comes as standard equipment for the FB-6A, it can be added as an option and can be changed to other machine guns. The total numbers of missiles carried by the launching vehicle of FB-6A remain the same as FN-6A, which is eight.^[10]

An upgraded version FB-6C was unveiled at the 2016 Zhuhai Airshow.^[11]

FN-16

At the 7th Zhuhai Airshow held at the end of 2008, China revealed a new addition to FN series MANPAD, FN-16. FN-16 is an improvement of earlier FN-6, with better all aspect attack capability and better resistance against electronic countermeasures. Another major improvement is in its seeker, which in addition to the original IR guidance, UV guidance is also incorporated,^[12] a practice adopted in the later version of FIM-92 Stinger. Like its predecessor FN-6, FN-16 can also be fitted with both IFF systems used on FN-6, and just like FN-6, FN-16 is re-designated as FY-16 (Fei Ying = 飞鹰, meaning Flying Eagle) when equipped with IFFs. The missile system is designed to counter fighter-bomber, attack aircraft, and helicopters. UAV, cruise missile etc.^[12]

HN-6

HN-6 is a further development of FN-16 in Chinese military service. HN-6 utilizes fire control systems (FCS) of earlier FN-6 and FN-16 MANPADS, but a new FCS sight of unknown designation has also been developed.^[13]

In addition to improved performance over the original FN-6/16 MANPADS, HN-6 incorporates a protective cap over the seeker of missile, offering better protection against the environmental elements.^[14] Based on the photos and video clips of PLA training, this protective cap needs to be manually removed before firing the missile.^[15]

HN-6 can also be incorporated into a portable tripod firing station similar to that of RBS 70 and Mistral. A seat is attached to the lightweight tripod firing stand that can be folded for transportation and storage, and the operator is protected by a bulletproof glass shield.^[16]

Syrian Civil War

The combat debut of the FN-6 came during the 2013 phase of the Syrian civil war.^[17] By March 2013, two Syrian Air Force Mil Mi-8 or Mi-17 were shot down.^[18]

The New York Times reported that Qatar supplied the Syrian rebels, possibly through purchase from the Sudanese inventory, with the FN-6 and that several units have now fallen into the hands of ISIS. However, spray paint had been used to obscure serial numbers in an effort to impede tracking of the weapon's supply chain.^[19]

The Global Times, states that, though Chinese-made missiles have downed aircraft in the past, the Syrian war "is the first time such a success has been recorded on video." The news outlet further raises the possibility of this improving the sales and image of Chinese defense products abroad.^[18] The New York Times, though claims that rebels have complained the missile's performance, such as failings to fire or lock on and two premature explosions while firing, which killed two rebels and wounded four more.^[19]

On 18 August 2013, the first recorded kill of a fixed-wing aircraft took place when a team from the Islamic Harakat Ahrar ash-Sham Al Islami brigade downed a SyAAF MiG-21 over Latakia province. The jet's pilot was filmed parachuting but his fate is not known. This downing is also the FN-6's first jet kill.^[20]

ISIL in Iraq

In the aftermath of the 2014 ISIL offensive in Iraq, on 3 October, an FN-6 allegedly supplied by Qatar was used by the militant group to shoot down an Iraqi Army Mil Mi-35 attack helicopter near Baiji.^[21] It also may have been used to destroy a Bell 407 scout helicopter in the same area on 8 October, killing both pilots.^[22]
