HQ-22

A Chinese medium/long-range surface-to-air missile system designed as a lower-cost complement to the HQ-9, exported as the FK-3 and notably operated by Serbia — the first European customer for a Chinese strategic air-defense system.

Overview

The HQ-22 (Hongqi-22, export designation FK-3) is a medium/long-range, road-mobile surface-to-air missile system fielded by the People’s Liberation Army Air Force (PLAAF) and exported to Serbia. Developed as a more economical partner to the high-end HQ-9B, it fills the layer between medium-range systems and the longest-range area-defense batteries, engaging aircraft, cruise missiles, UAVs and helicopters. Its delivery to Serbia in 2022 via PLAAF Y-20 transports made it the first Chinese strategic SAM to enter service on the European continent, a shift that carries both air-defense and geopolitical weight.

Development

The HQ-22 was developed by CASIC as a successor to the earlier HQ-12/KS-1 family, with a focus on balancing capability and cost. Initial operational capability with the PLAAF is estimated at around 2017, according to the Mitchell Institute for Aerospace Studies. The export variant, FK-3, was first delivered to Serbia in April 2022, with China’s Y-20 transport aircraft flying the system directly to Belgrade in a move that both showcased the PLAAF’s strategic-airlift reach and cemented Sino-Serbian defense cooperation, as reported by Defense News. Serbia reportedly received approximately three batteries and around 300 missiles by early 2023.

Design & capabilities

The HQ-22 is a vertical-launch system that employs semi-active radar homing, with multiple open-source accounts also pointing to an inertial mid-course guidance with track-via-missile (TVM) capability, as detailed by Missilery.info. Its H-200 multifunction PESA engagement radar works alongside a JSG-100 acquisition radar to detect and track targets. The Mitchell Institute cites a published engagement range of approximately 170 km, though other estimates place the figure closer to 120 km; the altitude ceiling is widely assessed at up to 27 km. The missile family, whose full designations have not been publicly released, is housed in four-round canisters on a wheeled 8×8 transporter-erector-launcher (TEL) that provides a road range of about 800 km at speeds reaching 65 km/h. The system is designed to engage aerodynamic targets — aircraft, UAVs, cruise missiles and helicopters — and the manufacturer claims a limited ballistic-missile capability as well.

Variants

The baseline HQ-22 has a reported improved variant designated HQ-22A, while the export FK-3 is the configuration delivered to Serbia. Little open-source information delineates the differences between these sub-variants.

Combat record / operational use

As of mid-2026 the HQ-22/FK-3 has not seen combat, so no empirical performance data exists. The Serbian FK-3 batteries have, however, been exercised in air-defense and counter-drone scenarios, a development noted by RFE/RL. These drills reflect Serbia’s integration of the system into its larger air-defense architecture, but no live-fire engagements have been publicly recorded.

Advantages

• Lower-cost complement to the HQ-9B, allowing a deeper deployment of medium/long-range SAM coverage.
• Road-mobile 8×8 TEL enables rapid relocation and complicates adversary targeting.
• Places Chinese strategic SAM technology inside a European NATO-adjacent state, giving Beijing a geopolitical and industrial foothold.
• Simplified logistics relative to the more complex HQ-9 family.

Drawbacks / limitations

• No combat record; all performance claims are untested outside training and testing.
• Lower-tier compared with the HQ-9B — shorter published range, likely less advanced radar and missile seekers.
• Key parameters (reaction time, simultaneous engagements, missile designations) are not publicly established, limiting independent assessment.
• PESA-based fire-control radars reflect an older technology baseline relative to contemporary AESA trends.
• The Serbian FK-3 deployment, while symbolically significant, sits within a modest fleet of only a few batteries.

Counterparts

• Patriot PAC-3 (USA)
• S-400 Triumf (Russia)

Outlook

The HQ-22 remains in production and active PLAAF service, though open-source fleet numbers are not available. Serbia’s adoption has demonstrated that the FK-3 can be a viable export product, and China may leverage that reference to pursue additional customers, particularly among states seeking a politically neutral, lower-cost SAM. Until combat data emerges, however, the system’s reputation rests on paper specifications and the strategic signal of its European deployment.
