QW-19 MANPADS / Qianwei-19 / Vanguard-19

The Qianwei-19 air defense missile (code: QW-19) is the latest member of China's "Qianwei" missile family. It is a new model specially developed for cruise missiles and treetop killer gunships. It uses dual-band infrared passive guidance to detect the target tail flame and other heat sources, so as to firmly lock the target, and the combat transition time is ten seconds. The avant-garde 19 is an improved model of the avant-garde 18, the Avant 18 is actually an improved model of the Avant 1. The Avant 19 can be seen as a depth-boosting model of the Avant 1 (Otherwise it would be impossible to develop that many models in a short period of time.)

The anti-jamming capability of the avant-garde-19 (QW-19) is extremely strong. It adopts advanced "trigger + laser proximity" composite fuze and digital information processing technology, which can make the missile explode when it hits or approaches the target. It is very effective for intercepting small targets such as cruise missiles that are difficult to hit directly, as well as low-altitude helicopter targets.

Ultra-low-altitude penetration tactics are very effective in modern warfare. Whether it is a fighter or a missile, this method is generally used to penetrate. Therefore, how to deal with low-altitude penetration fighters and missiles has become a headache for field air defense forces. In addition to short-range air defense missiles and anti-aircraft artillery, there is another weapon that is also very effective against ultra-low-altitude penetration, which is individual air defense missiles.

Avant-garde individual air defense missiles attracted widespread attention after their first public appearance at the Farnborough Air Show in 1994. Qianwei-19 and other types of individual air defense missiles. In particular, the Qianwei-11 and its later developed models have great interception capabilities for cruise missiles, and can be used as an important supplement to the field air defense of troops.

When cruise missiles and fighter planes use ultra-low altitude penetration, they will find that the distance will be greatly shortened, so the reaction time left for the troops is also very small. General air defense missiles may not respond at all, while avant-garde individual air defense missiles can be used within 10 seconds. Completing combat preparations within a short period of time is perfect for intercepting subsonic cruise missiles.

In addition to the air defense missiles carried by individual soldiers, there are also air defense missile combat units launched by vehicles and warships, which can meet the combat needs in different environments. It can be said that with the avant-garde series of individual air defenses, the frontier protection is greatly improved, and the probability of being attacked during the march and causing heavy casualties will also be greatly reduced.

The launch tube and missile size of the Vanguard 19 is not much different from that of the Vanguard 1. The main performance parameters are also similar. The total weight of the Vanguard 19 missile system is 16.5 kg. The total length of the launch tube is 1.576 meters, the length of the missile is 1.526 meters, the weight of the 71mm warhead of the bullet mirror is 1.42 kg, and the carrying capacity is 0.57 kg. The range is 500 ~ 5,000 meters, the maximum shooting height is 4,000 meters, and the minimum shooting height is reduced from 30 meters to 15 meters, which improves the interception capability of ultra-low-altitude targets such as cruise missiles and armed helicopters. The missile has a maximum flight speed of 600 m/s and can intercept targets with a maximum speed of 300 m/s.

Avant 19 uses world advanced level equipment of Dual frequency infrared seeker non-temperature identification anti-jamming technology. Infrared function obvious target engine tail nozzle accurate detection is possible. Target body skin temperature is caused by friction with air. Infrared characteristics of different bands Perform precise detection. At the same time, for the target, Infrared radiation in two bands identification and tracking than single infrared band tracking, stronger anti-interference ability and higher sensitivity.

All-round attack power can be more effective against highly mobile targets. In addition, the avant-garde 19 uses a large number of digital electronic components to replace the old-fashioned electromechanical analog components, which greatly reduces the weight of electronic equipment and improves the performance of electronic equipment. By comparing the slight difference between the temperature of the target and the characteristic temperature of the surrounding background where the target is located, it is possible to be in a complex background environment. (For example, complex terrain such as dense forests, mountains, etc.)

Compared with the relay-type steering gear used in the avant-garde 1 and avant-18 , although the electric steering gear used in the avant-garde 19 is more expensive, its technical level is much higher, and the flight control of the electric steering gear is more scientific and reasonable, which can eliminate a considerable part of it. The unfavorable factors for the missile flight effectively improve the flight speed and accuracy of the missile, which is very beneficial for intercepting low-altitude small targets such as cruise missiles, armed helicopters, drones and guided bombs.

The avant-garde 1 and Avant 18 adopted a trigger fuze that can only be triggered if it hits the target, which requires a high accuracy of the missile's hit. There are some deviations, and the target can avoid disaster. It is not conducive to intercepting ultra-low-altitude small targets such as cruise missiles and drones. In response to this situation, the avant-garde 19 adopts a more advanced triggering of the Laser Proximity Fuze, can be accurately measured and determined by laser within a certain distance close to the target best kill range. Direct detonation greatly improves the hit rate and killing effect on small targets.

In addition, Qianwei 19 also forward-lookingly uses the missile initial guidance technology, which can guide the missile in the early stage after it is launched, and guide the missile to the incoming direction of the target , so that the missile does not need to do useless work and can be captured more quickly and effectively. To the target, this is similar to the fiber-guided missile , which can greatly improve the anti-jamming capability and hit rate . Moreover, since the missile only needs to be guided at the initial stage , the time required is very short, and the safety of the shooter is also greatly improved.

although the avant-garde 19 is a missile with new wine in an old bottle , the adoption of many new technologies has brought its performance to the world's advanced level. Moreover , many parts of the Vanguard 19 are common to the Vanguard 1 missile , and are highly unified with the Vanguard 1 in terms of daily use and maintenance . This is very attractive to countries that have purchased the Vanguard 1, and the price is also lower. The export of missiles is also more favorable.
