"Serbia" plans to purchase the Chinese "HQ-9" surface-to-air missile systems, announced President "Aleksandar Vučić". If the deal is finalized, Belgrade will acquire one of the longest-range ground-based air defense systems in Europe – a step which, according to specialized publications like "Military Watch Magazine", could significantly change the balance of power in the region.
Abandoning Russian S-300s and S-400s, course towards Chinese HQ-9
The decision to orient towards the "HQ-9" comes after Serbia abandoned its plans to acquire Russian "S-300" or "S-400" systems. Instead, Belgrade has gradually built cooperation with the Chinese defense industry. As early as 2022, the Serbian armed forces commissioned medium-range "HQ-22" systems, which can work in conjunction with the "HQ-9" as part of a multi-layered air defense system.
Such a configuration allows for the combining of systems with different ranges and characteristics – "HQ-22" for medium distances and "HQ-9" for long distances. Thus, the national air defense can build a denser and more flexible defensive belt around key facilities and territories.
Range up to 300 km and comparison with other systems
According to available data, the "HQ-9" can engage aerial targets at a distance of up to "300 kilometers". For comparison, the American "Patriot" system in its standard configurations has a maximum range of about "200 kilometers", and the French-Italian "SAMP/T NG" – approximately "150 kilometers".
If the information about the deal is confirmed, the only systems with a longer range in Europe could be the Russian "S-400s" deployed in "Belarus", provided they use "40N6" missiles with a maximum range of up to "400 kilometers". At the moment, there is no official confirmation that these specific missiles have been delivered to the Belarusian armed forces.
What the long range provides: aircraft, cruise and ballistic missiles
The long range of the "HQ-9" allows the system to intercept not only aircraft but also "cruise and ballistic missiles" long before they reach their targets. Instead of protecting only individual facilities, the complex can create a wide defensive perimeter that simultaneously covers military and civilian infrastructure – airports, command centers, power plants, transport hubs.
An additional advantage is the high speed of the missiles – they travel at a "speed of over 5000 km/h". The long range and high speed increase the probability of a successful interception: if the first missile does not destroy the target, the operators have time for a second or even a third attempt before the target leaves the engagement zone.
HQ-9 and the A2/AD concept
The "HQ-9" is also designed for creating a so-called "A2/AD" (Anti-Access/Area Denial) zone. Such a zone significantly complicates the operations of long-range radar surveillance aircraft, aerial tankers, and other key support assets. They are forced to operate at a greater distance from the front line and from potential targets, which reduces their effectiveness.
The complex also possesses "more powerful radars" compared to the "HQ-22s" already used in Serbia. The greater power and range of the radars allow long-range systems to improve the effectiveness of other elements of the national air defense – to detect targets earlier and provide information to other air defense assets.
Fast delivery: an advantage over Patriot
For Belgrade, a significant advantage is also the "relatively fast delivery" of the Chinese systems. In recent years, delivery times for the American "Patriot" have significantly lengthened due to the war in "Ukraine" and conflicts in the "Middle East", which have led to the depletion of interceptor missile stocks and the straining of production capacity.
In this context, Chinese manufacturers can offer shorter lead times, which is key for a state that wants to modernize its air defense in a relatively short time. Thus, Serbia is trying to avoid waiting many years for Western systems and to receive a functional complex in the foreseeable future.
How many HQ-9s will Serbia buy and who else uses the system
At the moment, Serbian authorities "have not announced" how many "HQ-9" batteries they intend to purchase, nor when the final contract might be signed. This leaves the question of the scale of the future Serbian air defense shield open.
Besides "China", the "HQ-9" system is also operated by "Azerbaijan", "Morocco", "Turkmenistan", "Uzbekistan", "Pakistan", and "Egypt". This shows that the complex has already been chosen by a number of countries with different regional challenges, which further reinforces interest in it as an alternative to Western and Russian systems.
For Serbia, the potential acquisition of the "HQ-9" means not only a technological leap in air defense but also a political signal: the country is strengthening its defense cooperation with China and aims to build a multi-layered shield that covers both national territory and key facilities in a wider perimeter.
