The HQ-9B, HQ-19 [THAAD counterpart], HQ-26 [SM-3 counterpart] and HQ-29
[PAC-3 counterpart] are designed primarily for Anti Ballistic Missile
capabilities. While the HQ-9A air defense variant of the HQ-9 series is
very well attested, the remaining theater missile defense interceptors
are poorly attested, and verge on being little more than rumors.
The only official document that clearly states the designation
HQ-19 is a
document entitled "The needs analysis propulsion system of tactical
missiles and direction of development for solid propellant engine",
dating from 2000 and written by the Institute 41 CCAC Group (China
Aerospace Science and Technology Corporation). This paper analyzes
firstly the risks and types of conflict that China may face up to 2010
(The document is dated 2000, and speaks of "in 10 years"), and gives
types of tactical missiles to develop a priority to deal with these
external threats. In subsection 3.4, a priority is given to the need for
an anti-missile system capable of intercepting high altitude heads
ballistic missile whose range is 3000km, phase re-entry. And in response
to this paragraph 3.4, in section 4.4 it is clearly stated "Developing
solid propellant engines that meet the needs of anti-missile systems
area at high altitude," a concept close to American THAAD ( Terminal
High Altitude Area Defense).
Finally, in paragraph 5.4 of the document, it gives the status of the
development of the HQ-19 motor - a solid propellant engine demonstration
with a specific impulse of 260s, mass ratio of 0.85 and able to provide
the necessary power for maneuverability 60g to track down the head of
ballistic missile, a "completed the design phase, fabrication and
testing", "testing validated the carbon fiber shell and propellant
N-15B."
The
HQ-19 missile is a project launched in the late 1990s. In 1995 the
Chinese started serious studies of a kinetic kill vehicle KKV under
Program 863. In 1986, to meet the global challenges of new technology
revolution and competition, four Chinese scientists, WANG Daheng, WANG
Ganchang, YANG Jiachi, and CHEN Fangyun, jointly proposed to accelerate
China’s high-tech development. With strategic vision and resolution, the
late Chinese leader Mr. DENG Xiaoping personally approved the National
High-tech R&D Program, namely the 863 Program. Implemented during
three successive Five-year Plans, the program has boosted China’s
overall high-tech development, R&D capacity, socio-economic
development, and national security. In April 2001, the Chinese State
Council approved continued implementation of the program in the 10th
Five-year Plan. As one of the national S&T program trilogy in the
10th Five-year Plan, 863 Program continues to play its important role.
In 1999, the first Chinese KKV made the suspension tests successfully
flight, China became the second country in the world to have mastered
the technology. The first test of V & V was held in 2003 with
success. It was in final certification. HQ-19 has a KKV of about 35kg,
the system performance would be similar to the US THAAD. Another R &
D document mentions a technology demonstration at the HQ-19 engines in
2000, led by the Academy 4 CCAC group. The demonstration also validated
"hull carbon fiber" and "rocket N-15B".
S-400 Triumf
It is believed by some that the Russian S-400 Triumf surface-to-air
missile system was a joint development program, but others say that
HQ-19 has nothing to do with S-400 [according to one source, "and I say
this with certainty." China has shown interest in acquiring Russia’s
newest long-range SAM, the S-400 TRIUMF, but a contract has not been
signed yet and Russian officials have stated China would not receive the
S-400 until at least 2017. This SAM can target aircraft, cruise
missiles, and tactical and medium-range ballistic missiles.
The deployment of the Russian S-400 surface-to-air missile system will
substantially improve China's air defense capability, military experts
said as Russian media reported 16 April 2015 that China has bought the
cutting-edge weapon.
"The S-400 is definitely one of the top anti-aircraft weapons in the
world. It will greatly supplement the People's Liberation Army's air
defense system, which now has some loopholes in long-range,
high-altitude defense of airplanes or ballistic missiles," said Wang
Ya'nan, deputy editor-in-chief of Aerospace Knowledge magazine.
"The system has multiple types of missiles with various ranges, enabling
it to safeguard a very large area of airspace. Some of its missiles are
even specifically designed to intercept ballistic missiles," Wang said.
"Moreover, some of its launch tubes can store and launch several
different missiles, which makes it very convenient and fast to use."
Russia has a long history of developing anti-aircraft and missile
defense weapons, so the S-400 is a concentration of some of the most
advanced missile technologies Russia has, such as an active
electronically scanned array radar, according to Wang. "China still
lacks experience in the development of long-range air defense systems,
especially those that can intercept ballistic missiles. There is no
shortcut because the development of such sophisticated weapons requires a
great number of experiments and tests. It is a matter of time and
resource input," he added.
According to Russian media reports, the S-400 is a new-generation,
anti-aircraft weapon system capable of engaging any aerial target,
including airplanes, helicopters and drones, as well as cruise and
tactical ballistic missiles, with a maximum speed of 4.8 km per second.
The system's 40N6 missile can destroy airborne targets at ranges up to
400 km.
Anatoly Isaikin, chief executive of the Russian state-run arms trader
Rosoboronexport, confirmed on Monday that China has a contract with his
company for the purchase of the S-400 air defense systems. "I will not
disclose the details of the contract, but yes, China has indeed become
the first buyer of this sophisticated Russian air defense system. It
underlines once again the strategic level of our relations," Isaikin
told the Russian newspaper Kommersant.
China clinched the deal in September at a cost of more than $3 billion
for the delivery of at least six S-400 battalions, Moscow Times
reported. Currently, China relied on its domestically developed HQ-9 and
the Russian-made S-300 missile system, according to Western military
observers.
Du Wenlong, a senior researcher at the PLA Academy of Military Science,
said the operational ranges of modern military aircraft and missiles are
much longer than their predecessors, so an effective defense system
must have long-range missiles that can hit aircraft as well as cruise
missiles and tactical ballistic missiles. "Our air force has deployed
the Russian S-300 systems, which are good at dealing with aircraft, but
their performance in intercepting cruise missiles and tactical ballistic
missiles is not very satisfactory," he said. "After we commission the
S-400, it can work with the HQ-9 and S-300 to form a fully covered air
defense network."
Zhao Zhihua, a senior missile researcher at China Aerospace Science and
Industry Corp, a major developer of China's missiles, said that through
the introduction of the S-400, China can gain a lot of experience and
expertise on how to operate a missile defense system. "Operating such a
complex system will go beyond our current knowledge and experience,
which in turn will teach us things that we don't know, so it is worthy
spending big money buying it," he previously told the Ordnance Industry
Science and Technology magazine.
HQ-19
HQ-9 launching

HQ-9 air defence system, with a range of about 200km (125 miles)
HQ-9’s guidance system is modeled on the Patriot’s. Which means that
the
HQ-9 might use the Patriot’s “track-via-missile” guidance system—allowing the HQ-9 interceptor to fly directly at an incoming
missile. The HQ-9—like the Patriot—would either explode as it nears the
target or directly hit the incoming missile.
Either way, the incoming
target is either destroyed or knocked off its trajectory.
Further, some sources suggest that the HQ-9—unlike its American and
Russian contemporaries —uses active electronically scanned array radar
technology.
