The HQ-22 (simplified Chinese: 红旗-22; traditional Chinese: 紅旗-22; pinyin: Hóng Qí-22; lit. 'Red Banner-22'; NATO reporting name: CH-SA-20) is a medium- to long-range semi-active radar homing/radio-command guidance air defence system developed and manufactured by the China Aerospace Science and Industry Corporation (CASIC).
The HQ-22 was publicly revealed at the 2016 China International Aviation & Aerospace Exhibition.
The HQ-22 entered service with the People's Liberation Army Air Force (PLAAF) by 2019.
Serbia purchased the FK-3, the export variant, in 2019; they were delivered by PLAAF Xi'an Y-20 transport aircraft and entered service in April 2022. They were the first Chinese medium- or long-range air defence system exported to Europe.
In April 2021, India reported that China had deployed the HQ-22 near eastern Ladakh.

The HQ-22 air defence system is a second generation development of the HQ-12 missile. It is intended as a low-cost replacement for the HQ-2.
The missile is "wingless" compared to the preceding HQ-12. The missile uses semi-active radar guidance to reduce cost, and may switch to radio command guidance in an environment with "strong electronic interference".
An HQ-22 unit includes four to eight transporter erector launchers, each with four missiles. The radar vehicle reportedly permits six targets to be engaged simultaneously.
