China has developed a new self-propelled anti-aircraft missile and gun system, designated SWS3 (in other sources WS-3) designed to counter low-flying threats such as drones, cruise missiles, and precision-guided munitions. Details are reported by Army Recognition, citing Chinese specialized and open sources.
The system combines twin 35mm autocannons with FB-10A short-range surface-to-air missiles, mounted on an armored 4x4 or 6x6 wheeled chassis that enables autonomous operation. In essence, SWS3 is a highly mobile, short-range air defense system optimized for rapid deployment and close-range engagements.

For detection, tracking, and targeting, the SWS3 employs a combination of electro-optical sensors and radar guidance. The platform also supports integration into a larger, layered air defense network, enhancing its effectiveness through coordination with other systems.
One notable feature of the SWS3 is its fire control system, which enables simultaneous, coordinated use of both guns and missiles. This dual-mode capability is intended to boost effectiveness during complex, large-scale attacks involving diverse targets at varying speeds and altitudes.
According to available information, SWS3 units have already been deployed within the Chinese military’s light motorized infantry brigades — a logical choice given the system’s mobility and its designed ability to counter drone swarms.
The system clearly draws conceptual parallels with russia’s Pantsir-S1 air defense system. Compared to its russian counterpart, the SWS3 offers improved mobility due to its wheeled platform, which allows for faster and more flexible deployment. The Pantsir-S1, however, retains an edge in all-terrain mobility thanks to its tracked variant, which, despite being slower, offers superior off-road performance.
That said, all of the SWS3’s claimed capabilities remain based on Chinese military statements. Without verified field data or operational performance records, any direct comparison remains speculative. Nonetheless, the system reflects a broader trend: the PRC is actively applying lessons from contemporary conflicts, investing not only in so-called "UAV innovation studios" and other drone projects but also in technologies countering them.
