The Z-20 is armed with a domestic QJH001 door machine gun
Recently, the domestic Z-20 tactical utility helicopter began to be equipped with the domestic QJH001 helicopter door machine gun, and the domestic helicopter door machine gun is being rolled out of equipment.
The domestic QJH001 helicopter door machine gun, with a caliber of 12.7 mm, was originally named the M17G type 12.7 mm helicopter door machine gun, from this number we can know that the gun is equipped with a Mi-17 transport helicopter. The M17G helicopter door machine gun is relatively rudimentary, the base is a simple tripod, which is inconvenient to move, which limits the firing range, and the helicopter vibration is directly transmitted to the machine gun, affecting the shooting accuracy.

The Z-20 tactical utility helicopter is equipped with a scale scale QJH001 door machine gun with a noticeable improvement. It is believed that after a period of application, the relevant units have been perfected and improved based on practical experience. The new QJH001 door machine gun replaces the original tripod with a hinge, and the hinge can also be adjusted. In this way, the QJH001 door machine gun can extend out of the hatch and expand the firing range like similar foreign models. In addition, the machine gun and the base do not seem to be fully combined, and it should have been installed flexibly to reduce the adverse effects of helicopter vibration on shooting.

The new gun carriage is similar to the foreign hinge gun carriage, with a better firing range
According to relevant information, the QJH001 helicopter door machine gun was developed from the QJC88 vehicle-mounted anti-aircraft machine gun, and the QJC88 anti-aircraft machine gun is a vehicle-fired anti-aircraft machine gun widely equipped by the Chinese Army, and the main anti-aircraft machine gun for domestic tanks and combat vehicles. Therefore, the QJH001 helicopter door machine gun can share logistics support resources with the QJC88 12.7mm vehicle-mounted machine gun, reducing costs and expenses. The QJC88 12.7 mm anti-aircraft machine gun is a derivative version of the domestic W85 12.7 mm anti-aircraft machine gun, the biggest feature of the W85 anti-aircraft machine gun is light weight, the total combat weight of the W85 anti-aircraft machine gun is only 38 kg, and the M2HB heavy machine gun empty gun weight reaches 38 male guns. Considering the high volume and weight requirements of the helicopter door machine gun, we chose the W85 anti-aircraft machine gun as the prototype gun.

It should be pointed out. The W85 12.7 mm anti-aircraft machine gun is the main model of our exports, since the 80s of the last century, the W85 anti-aircraft machine gun has been exported to dozens of countries, with more than 10,000 units. Therefore, the domestic helicopter door machine gun is developed from the W85 anti-aircraft machine gun, which is also conducive to performing tasks overseas, obtaining logistics support from the local area, and reducing the difficulty and pressure of our overseas logistics support.
According to outside information, the W85 anti-aircraft machine gun is powerful and has an effective firing range of more than 1500 meters. In the case of the use of armor-piercing incendiary shells, it is possible to penetrate 800 mm homogeneous steel armor at an inclination of 30 degrees at 10 meters. If a shell-piercing projectile is fired, it can penetrate 12 mm homogeneous steel armor with a 60-degree inclination at 600 meters, which is even more powerful than a 20 mm machine gun. In the modern battlefield, there are more and more light armored combat vehicles, and even military trucks are generally equipped with bulletproof materials to improve protection, so it is important to improve the armor-piercing ability of machine guns.

From here, we can see why the domestic Type 1 helicopter door machine gun chose a 12.7 mm caliber, that is, because of its high power, long range, and strong suppression ability. Based on the power of the domestic 12.7mm armor-piercing projectile, the QJH001 door machine gun can deal with most armored fighting vehicles in Taiwan, such as the CM21 armored personnel carrier, which is widely equipped in Taiwan, and the latest clouded leopard fighting vehicle can also penetrate its side armor. In this way, it will be able to significantly suppress the firepower of our airborne assault troops, and it will also help the airborne troops resist the counterattack of the opponent's armored forces after landing, and consolidate the airborne positions.
