CHL-906

History

The CHL-906 is a Chinese mobile integrated electronic warfare system combining electronic reconnaissance, passive detection, electronic attack, and command-and-control functions. It is designed to detect and track radar emitters while using dedicated jamming elements to reduce the effectiveness of hostile radar systems.

The system is intended to protect key areas, critical targets, and combat operations. Its architecture combines several specialized stations for radar reconnaissance, passive emitter location, long-range jamming, multifunction radar jamming, and countermeasures against millimeter-wave radar threats.

Algeria has procured CHL-906 systems as part of its broader electronic warfare and air-defense network. Vehicles associated with the system have appeared in imagery from Algerian military exercises, while a separate 2026 claim that a CHL-906 was positioned approximately 6 km from the Moroccan border has not been officially confirmed or supported by conclusive publicly available imagery. Pasted text

Technical descriptions of the CHL-906 were available by 2023 and identified the system as an integrated surface-based radar reconnaissance and jamming complex. The available evidence does not establish its original development date, first Chinese service date, or initial production date.

Design

The CHL-906 is organized as a mobile, multi-element electronic warfare system rather than a single radar or jammer. Its component stations divide the tasks of detecting electromagnetic emissions, classifying and tracking emitters, locating targets passively, and transmitting interference against selected radar systems.

Electronic reconnaissance

The ESM/ELINT station is intended to intercept, monitor, and track radar emissions in real time. Reported frequency coverage extends from approximately 0.1 to 40 GHz. Information collected by the reconnaissance element can support identification of radar types and the tracking of aircraft, unmanned aircraft, and other emitters through their electromagnetic activity.

A separate three-dimensional passive radar element is intended to intercept, locate, and track multiple radiation sources without relying on conventional active radar transmission. Its reported detection range against large radar emitters exceeds 600 km.

Electronic attack

The long-range radar jamming station operates against airborne early-warning radars in the L, S, and P frequency bands. Its purpose is to reduce radar detection performance, with a claimed jamming distance exceeding 300 km.

The multifunction radar jamming station combines reconnaissance and electronic attack against airborne multifunction radars. Its claimed jamming range exceeds 250 km.

A millimeter-wave radar jamming station is intended to conduct reconnaissance and jamming against millimeter-wave radars used by helicopters and precision-guided weapons. Its specified jamming-distance relationship is greater than 1.2 times the working range of the targeted seeker.

Command and control

The CHL-906 integrates reconnaissance and jamming functions under a command-and-control architecture. This arrangement allows detected radar emissions to be used for electronic intelligence while supporting the selection and coordination of appropriate jamming elements.

Additional descriptions attribute the system with the ability to interfere with communications, unmanned-aircraft data links, and satellite-navigation signals. These capabilities and the quoted range figures should be treated as claimed system performance because the available evidence does not establish demonstrated combat effectiveness at those distances.

Operational history

Algeria is a confirmed foreign customer for the CHL-906. Vehicles associated with the system have been shown during exercises in Algeria's 3rd Military Region in the southwest of the country. The procurement places the CHL-906 within a wider Algerian network of ground-based air-defense and electronic-warfare equipment.

In February 2026, an unverified claim stated that Algeria had deployed a CHL-906 approximately 6 km from the Moroccan border. No official Algerian confirmation, conclusively verified geolocation, or definitive imagery establishing the system at the stated position was available in the supplied evidence. The claimed border deployment therefore remains unconfirmed.

Operators

• Algeria — CHL-906 systems have been procured and vehicles associated with the system have appeared during military exercises. The number acquired is not established by the available evidence.
