The HQ-9 development program started in the 1970s, with full-scale development beginning in the late-1980s.[8]
According to Western analysts, the HQ-9 is "equivalent"[9] to or a derivative of the Russian S-300, which China started importing in 1993.[10][3][4] Justin Bronk of the Royal United Services Institute describes the missile as a "hybrid design based on the Russian SA-20 but with radar, seeker head and C2 elements heavily influenced by American and Israeli technology."[9]
The missile uses track-via-missile (TVM) guidance combining inertial guidance, mid-course uplink, and terminal active radar.[11] The TVM used on earlier missiles may have been developed from a United StatesMIM-104 Patriot missile purchased from Israel or Germany.[6]
According to a 2001 article from Defence International, the HQ-9 is 6.8 m. long with a mass of nearly two tons. The diameters of the first and second stages are 700mm and 560mm, respectively. The warhead mass is 180kg, and the maximum speed is Mach 4.2. The HQ-9 may use fire-control radars from other Chinese SAM systems.[12]
Variants

Air defense
HQ-9 — Original variant. NATO reporting name: CH-SA-9.
Changchun (150) equipped with HHQ-9.
HHQ-9 — Naval surface-launched variant.[3] NATO reporting name is CH-SA-N-9.[7]
HQ-9A — Improved version, first tested in 1999 and service entry in 2001.[1]
HQ-9B — Improved version with a range of up to 260km and added passive infrared seeker.[4] Reportedly tested in February 2006.[1] NATO reporting name is CH-SA-21.[7]
HHQ-9B — Naval surface-launched variant of HQ-9B; NATO reporting name is CH-SA-N-21.[7]
HQ-9C — Improved ground-based missile system, can intercept ballistic missile targets at their terminal phases.[13] The HQ-9C also has slimmer missiles compared to the regular HQ-9, with each vehicle capable of carrying eight interceptors.[14]
HHQ-9C — Naval surface-launched variant of the HQ-9C.[14]
Ballistic missile defense and anti-satellite
HQ-19 (NATO reporting name: CH-AB-2)[15] – Anti-ballistic missile variant, reportedly designed to counter medium-range ballistic missiles. It targets ballistic missiles in their midcourse and terminal phases, and it is comparable to the US THAAD.[16] The missile may have "begun preliminary operations" by 2018.[17]
Export
FD-2000 (Chinese:防盾-2000; pinyin:Fáng Dùn-2000; lit.'Defense Shield-2000') – Export variant with a range of 125km.[6] May be fitted with YLC-20 passive radar against stealthy targets.[18] May use the HT-233 target-acquisition radar,[19] Type 120 low-altitude search radar, and Type 305A AESA search radar.[18]
FD-2000B – Export variant with a range of 250km.
HQ-9P – Custom variant for Pakistan. Range of 125km for interception against aircraft and around 25km against cruise missiles.[20][21]
Foreign interest
Turkey
The HQ-9 was a contender in Turkey's T-LORAMIDS program, and it was reportedly selected as the winner in September 2013.[22] The United States responded by blocking funds to integrate the Chinese system into NATO defenses.[23] However, through 2013 there was no confirmation that the deal had been finalized.[24][25][26] In February 2015, the Grand National Assembly of Turkey was informed by the Ministry of National Defence that the evaluation of bids was complete and that the chosen system would be used by Turkey without integration with NATO; the system was not explicitly named. However, other Turkish officials reported that no winner had been selected.[27] Later in the month, Turkish officials revealed that negotiations were ongoing with multiple bidders; the Chinese bid had not yet satisfied requirements concerning technology transfer.[28] In March 2015, a China Daily article reported that it was "well-known that the Chinese FD-2000 system, a HQ-9 model for export, was chosen for the contract with Turkey in 2013" based on comments made by a CPMIEC representative at the 2015 Langkawi International Maritime and Aerospace Exhibition; the article was misleadingly called "Missile sale to Turkey confirmed."[29] In November 2015, Turkey confirmed it would not purchase the HQ-9, opting for an indigenously developed system instead.[30]
The naval variant, the HHQ-9, was deployed by the PLAN by 2009. It was first carried by the Type 052C destroyer.[37]
Pakistan
The Pakistan Army operates the HQ-9/P variant.[21] Negotiations for the purchase of the HQ-9 and HQ-16 by Pakistan began in early 2015.[38] The system officially entered service on October 14, 2021.[21] The HQ-9/P's first combat use was during the 2025 India–Pakistan conflict[39][40]
Egypt
It was reported that Egypt had acquired HQ-9B systems in mid-2025 by the Middle East Monitor,[41] and in December 2025, it was reported that the Egyptians had deployed the system as part of an A2/AD system in the Sinai near Israel in a major move to boost aerial defenses not done since 1979.[42]
