Known as the "Red Banner," the HQ-9 SAM is China's indigenous long range air defense system, complementing Russian made S-300 missiles. The system is mounted on an 8x8 wheeled truck, each carrying 4 missiles. The missile itself has a top speed of Mach 4.2, range of 200km and a flight ceiling of roughly 27-30km. In addition to the ability to target aircraft, drones and cruise missiles, the HQ-9 also has a limited anti-ballistic missile and anti-surface capability. While the missile currently uses semi-active radar homing and infrared guidance to hit targets, future upgrades would increase range and add on an active radar seeker. Compared to most Patriot and S-300 variants, the HQ-9 uses a more advanced AESA radar, the giant HT-233 truck mounted radar, for its fire control, which offers better performance against enemy jamming and stealth aircraft. The U.S. Defense Department estimated that China had about 96, 4 missile HQ-9 launch vehicles, in addition to over a dozen Type 052C and 052D guided missile destroyers, which respectively can carry 48 and 64 HQ-9 SAMs. The HQ-9 launcher is compact enough, with a height of 3.2 meters, 2.8 meters wide and 10-11 meters long, to fit into the Y-20 heavy transport aircraft, or a Type 726 overcraft.
