China Unveils Yitian II 8x8 SHORAD System with 20 km Missiles as US Forces Face Drone Threats.

China’s GAS8 Yitian II short-range air defense system was unveiled as a mobile counter to drones, helicopters, and low-flying threats, with its debut at the SAHA 2026 exhibition in Istanbul highlighting Beijing’s push to strengthen frontline air defense against increasingly dominant aerial risks. The system’s introduction, showcased during the May 5–9 event, signals a focus on protecting maneuver units from precision strikes and persistent UAV surveillance that now define modern combat environments.

Mounted on an 8x8 armored vehicle, the Yitian II integrates search radar, fire-control radar, and eight ready-to-launch missiles into a single platform, enabling rapid detection and engagement without external support. This self-contained design enhances battlefield survivability and mobility, reflecting a broader trend toward highly autonomous short-range air defense systems built to keep pace with fast-moving ground forces.

The Yitian II follows the original Yitian concept, which appeared publicly in 2004 and used the TY-90 missile, a weapon derived from Chinese helicopter air-to-air missile development. Earlier Yitian versions combined a 3D radar, electro-optical sighting, automatic target tracking, and eight TY-90 missiles on vehicles such as the WMZ-551 6x6 armored personnel carrier, creating a compact air defense layer for troops on the move and fixed sites.

The project’s development reflects a clear Chinese shift from very short-range infrared missile carriers toward more autonomous, sensor-rich SHORAD vehicles. Open-source exhibition references link the Yitian II to Chinese displays from the 2022 Zhuhai Airshow, where it was also associated with the Sky Dragon 20 designation, TY-20 missiles, a search radar, and a tracking radar on an 8x8 armored chassis.

The Yitian II moves the design into a heavier and more capable class. Display information describes an 8x8 armored chassis with a road speed above 100 km/h, a launcher search radar range of at least 18 km, a command vehicle search range of 50 km, and a reaction time of seven seconds or less, figures that indicate a system intended to keep pace with fast mechanized formations rather than sit as a static point-defense asset.

Its sensor architecture is the core difference from older Yitian vehicles. The combination of a 3D surveillance radar, solid-state AESA tracking radar and 10 km infrared electro-optical channel allows the crew to detect, classify and engage low-altitude targets while retaining a passive option when radar emissions would expose the unit. That mix is particularly relevant against small unmanned aerial vehicles, hovering helicopters and cruise missiles flying close to terrain.

The armament consists of eight Tianlong/TY-series missiles, with the Yitian II promoted around TY-20I imaging-infrared and TY-20R active-radar homing interceptors while retaining compatibility with TY-90 missiles. The TY-20 family extends engagement reach to about 20 km, while the TY-90 remains a close-layer missile generally associated with 6 km range and about 4 km altitude in land-based Yitian service.

This missile mix is tactically important because it gives a battery different seeker options against different target signatures. An active-radar missile can attack targets with weak heat signatures or difficult closing angles, while an imaging-infrared missile can engage with reduced radio-frequency emission and better discrimination against decoys. A two-way datalink, as described in exhibition material, further allows mid-course updates and improves the probability of intercept against maneuvering targets.

In a mechanized brigade, the Yitian II would normally operate as a mobile SHORAD troop attached to the air defense battalion. Vehicles could move behind main battle tanks, infantry fighting vehicles and self-propelled howitzers, halt briefly under camouflage, receive a target track from their own radar or a higher-echelon early warning sensor, fire one or two missiles, then displace before hostile artillery, loitering munitions or anti-radiation weapons can respond.

For a country acquiring the Yitian II, the most effective use would be a layered defense rather than an isolated deployment. The system would cover command posts, bridging sites, air bases, ammunition dumps and advancing armored columns, while longer-range systems deal with combat aircraft at medium altitude and gun or laser systems defeat very small quadcopters at lower cost.

The development path also shows how NORINCO is adapting the Yitian family for export demand. Laos displayed Chinese-made Yitian, or Tianlong 6, air defense systems in 2019, while Mauritania received the lighter Yitian-L armed with four TY-90 missiles on a Dongfeng tactical vehicle; open-source reporting in April 2026 also indicated that Mali had taken delivery of Chinese-made short-range air defense systems assessed as Yitian-L vehicles.

No confirmed operational user of the Yitian II itself has been publicly identified, but the presence of Yitian-family vehicles in African and Southeast Asian inventories suggests that China is offering a scalable product line: Yitian-L for light forces and border defense, original Yitian/Tianlong 6 for short-range mechanized protection, and Yitian II for forces needing greater range, mobility and sensor autonomy.

Compared with the U.S. AN/TWQ-1 Avenger and older French SANTAL-style missile carriers, Yitian II offers a larger missile reach and a more complete onboard sensor package. Against Russian Pantsir-S1 or Tor-M2E, it lacks an integrated cannon or deeper vertical-launch missile magazine, but its dual-seeker missile concept, 8x8 mobility and lower apparent complexity could appeal to armies that want a brigade-level air defense vehicle without the cost and sustainment burden of heavier systems.

The main limitation is magazine depth. Eight ready missiles are adequate for ambush defense or a short engagement sequence, but a drone swarm or repeated cruise missile raid would force rapid resupply unless the Yitian II is combined with guns, electronic warfare systems and cheaper interceptors. The system’s effectiveness will therefore depend less on the launcher alone than on command integration, reload discipline, radar survivability and the density of supporting sensors.

Yitian II’s operational relevance is clear: it is designed to close the gap between man-portable missiles and medium-range air defense in the area where modern armies are suffering most losses from unmanned aerial vehicles and low-altitude precision weapons. For potential buyers, the attraction is a mobile missile carrier able to accompany armored units, protect dispersed infrastructure and contribute to a layered air defense network; for China, it reinforces a broader push to sell export-ready ground-based air defense systems into markets where drone warfare has changed procurement priorities.
