Frequently Asked Questions
What is the main difference between Arrow-3 and HQ-9?
The main difference between Arrow-3 and HQ-9 is their intercept altitude and engagement time. Arrow-3 is an exoatmospheric interceptor that can engage ballistic missiles in space before reentry, while HQ-9 is a long-range surface-to-air missile system that operates at lower altitudes and has a shorter engagement time.
Which system is more accurate?
Both systems boast high accuracy rates, but Arrow-3's two-color infrared seeker provides a slight advantage in tracking and engaging targets.
Which system is more cost-effective?
HQ-9 offers better value for money in scenarios requiring high-volume engagements, while Arrow-3's higher cost per interceptor is justified by its unique exoatmospheric intercept capability.
Has HQ-9 been used in combat?
No, HQ-9 has not been used in combat but has been regularly exercised in PLA drills.
Can Arrow-3 engage cruise missiles?
No, Arrow-3 is not designed to engage cruise missiles, which operate at much lower altitudes.
