40-mm T92 anti-aircraft gun

The 40mm/L70 anti-aircraft gun was jointly developed by Taiwan and Singapore. It started in early 1982 and continued until 2012.

In the 1970s, there was a rift in the relationship between Taiwan and the United States, and the purchase of weapons from the United States was blocked. As a result, Taiwan took advantage of its economic boom and turned to purchase European arms, including Swiss Double 35 anti-aircraft guns. Before purchasing the twin 35mm anti-aircraft guns from the Swiss Oerlikon Company, Taiwan compared the guns with the L70 40mm single-barrel towed anti-aircraft guns from the Swedish Bofors Company. The result of the comparison was that the performance of the two guns was comparable, and the opinions within the Taiwan military were not unified. The comparison work ended hastily.

When these anti-aircraft guns arrived in 1981, Taiwan found itself facing greater air defense pressure. The Taiwan military believed that such an air defense network is not enough to deal with the attack of nearly a thousand fighter planes from the mainland, and it is necessary to strengthen the anti-aircraft artillery force. As a result, the Swedish Bofors 40mm anti-aircraft gun, which had been dormant for a long time, was brought out to compete with the double-35 anti-aircraft gun. At that time, the Swiss double-35 anti-aircraft gun had just entered Taiwan.

In the past few decades, the Taiwan military has conducted many live-fire target shooting tests on single 40-type anti-aircraft guns and dual-type 35-type anti-aircraft guns. Especially in 1983, the Taiwan military's navy, army and air force participated in the target shooting tests of the two types of anti-aircraft guns. The results showed that the dual-type anti-aircraft guns were The hit rate of the 35mm anti-aircraft gun is about 78%, and the hit rate of the single 40mm anti-aircraft gun is about 62%. However, the hit and damage rate of a single gun was exactly the opposite. Taken together, the two guns were evenly matched,

In 2005, a radically upgraded 40-mm T92 anti-aircraft gun was demonstrated to the general public. This sample, created on the basis of the Bofors L70, is a joint development of the Singaporean company AOS and the 202nd Artillery Arsenal. Joint Logistics Factory 202 was previously committed to developing the T-92 40mm cannon, while the Joint Logistics Factory 205 only had production experience with the T-75 20mm cannon, so neither had experience in developing 30mm cannons; after negotiation , the research and development of the 30mm cannon fell on the Lianqin 202 Factory. To this end, Lianqin 202 Factory specially removed the 30mm cannon from the A-3 attack aircraft prototype converted from an AT-3 trainer aircraft by the aviation development center for research, and introduced the country's Flying Tiger 30mm air defense to South Korea through pipelines The KCB 30mm cannon of the gun carriage, however, this cannon and artillery shells are mainly designed for air defense and do not have suitable anti-armor ammunition (this problem is similar to the domestic T-75 20mm cannon), and its design is also relatively old.

According to widespread promotional materials, the new 40-mm anti-aircraft gun weighs about 6 tons, and its effective range against air targets is 4 miles. In addition to the standard ammunition for the Bofors L000, the T330 mount can fire programmable projectiles with detonation at a given point or projectiles equipped with a radar fuse that fires when flying close to the target. An increased probability of defeat is obtained thanks to ready-made lethal elements in the form of tungsten balls. The installation is capable of rotating in any direction with a pointing speed in the horizontal plane up to 85 ° / sec. Elevation angles: from -4° to +80°, pointing speed in the vertical plane 45°/sec.

The barrel of the T92 anti-aircraft gun is equipped with a heat-insulating casing, which makes it possible to exclude the influence of external meteorological factors and improve firing accuracy. In this case, the barrel has forced cooling.

The gun is served by 5 people, but it is controlled by one gunner. To aim at the target, the shooter uses an optoelectronic system with a built-in thermal imager and a laser rangefinder. The detection range of OLS reaches 10 km. Own sights provide shelling of air targets flying at speeds up to 700 m/s. In case of failure of complex electronics, the installation is equipped with an optical sight.

It is possible to remotely control the T92 installation when the shooter is in a safe shelter. A battery of four guns is attached to a small-sized Tianbing search and sighting radar, with the help of which group guidance of 40-mm anti-aircraft guns is carried out. A radar station operating in the centimeter frequency range can detect and track a cruise missile at a distance of 20 km and simultaneously track 20 targets. The target can be fired upon 4,5 seconds after being detected.

The T92 anti-aircraft gun is towed by a 5-ton truck with a maximum speed of up to 60 km/h. Transfer from marching to combat position takes 5 minutes. During tests, the 40-mm installation showed good results when firing at small speed boats. In the case of equipping firing positions on the coast, the battery of T92 guns is able to control the sea area at a distance of up to 8 km.

The T-92 is actually just a prototype. After the Chinese Academy of Sciences took over and incorporated the Jinnu project, it also spent a lot of time on fire control improvements. At the 2017 Taipei Aerospace Exhibition, the commentator said that 6 rounds can destroy an aerial target.

Factory 202 lacks advanced technology. The ability to integrate air defense systems means that the manufactured equipment will be out of date before it is put into service. There is no possibility of defeating the products of foreign manufacturers. Naturally, it is impossible to create weapons that meet the military's urgent needs for future war environments. They can only imitate the artillery body. If you make a hasty communication, failure is inevitable.
