Chengdu j20 China’s most powerful stealth fighter jet


In this blog, I am going to tell you about the 5th generation fighter plane of China Chengdu j20.

Many countries in the world are engaged in making the 5th generation fighter plane, but so far only a few countries have been able to acquire this technology, including America, Russia and China. India is also involved in this race and shortly after The pass will also have its own Fifth Generation fighter plane.

While the US worked on the f-22 Raptor and f-35 for the fifth-generation fighter plane, Russia has developed the Su-57 as the 5th generation fighter plane.

China has worked on Chengdu j20 as a 5th generation fighter plane.

Chengdu J20 is a 5th generation fighter aircraft equipped with stealth features. This fighter is developed by Chengdu Aerospace Corporation for PLA (people liberation army/airforce).

China has tried to keep this project as a super-secret project.

As America and Russia, China also started making the fifth-generation fighter in the 90s, at that time, China worked on the j-x6 program.

Under the j-x6 program, China was to develop Fourth Generation Fighter for PLA as well as Fifth Generation Fighters, and under the Fifth Generation Fighter Program, Chengdu Aerospace was awarded a project of j-20 in 2008.

PLA officially released in 2009, stating that the first flight of Generation Fighter will be done again from 2010 to 2011 and this fighter will be in service by 2019.

By 2010, Chengdu Aerospace has developed two prototypes. The first prototype was also tested on 22 December 2010, followed by Chengdu j20 completing its first flight on 11 January 2011, a test flight of about 15 minutes.

After the first flight test was successful, it had its second flight test on 17 April 2011, which was a flight test of about 20 minutes. On 5 May 2011, it had another flight test which was about 55 minutes in which this fighter jet’s landing gear Was tested.

On 26 February 2012, Chengdu j20 also performed manoeuvres on low altitude.

On 10 May 2012, a taxi trial of the second prototype of the Chengdu j20 was also carried out, and its flight tests started soon after.

On 20 October 2012, a picture of a new prototype was revealed in which the AESA radar was tested and even after that, every prototype that made it had some other changes.

The test of another new prototype started on 13 September 2015, marked as 2016.

In 2016, a number of improvements were made such as the use of divertless supersonic inlet intakes which reduced its weight, radar signature and design complex.

The Chengdu j20 uses a Russian-made engine called the AL31 and the Chinese WS, although China has planned that the WS-15 engine will be fitted in the j20 by 2020.

The 2016 engine is housed inside the stealthy fuselarge as compared to the prototype 2014 and 2015, which has further increased its stealth.

Another prototype 2017 flight test was done in November 2015. Some changes were made to the cockpit of this prototype which increased the visibility of the pilot.

The prototype was the last prototype of the 2017 j20. Since then, the initial production of the j-20 has been started. However, despite the design and development of this fighter, technical problems such as its control system, stealth coating and infrared sensors have been identified. But still wor


Chengdu j20 was introduced in March 2017, so far it has built eight prototypes and 20 initial production fighters which have been inducted into the PLA.


The j-20 has a long and wide fuse large with jijldnose section and frameless canopy.

The j20 canopy matches the f-22 raptor’s canopy to a great extent, to the point of the intakes, which are not easily placed behind the cockpit and canards are placed behind the intakes.

Its rear section uses two outworlds canted all moving fance caught and deep ventral strics and the Conventional round engine and exhaust.

1856 transmitter-receiver module with type 1475 KLJ5 active electronically scanned array radar.

Its nose section has an electro-optical and infrared targeting system as well as an advanced communication suite with the help of which it can share fighter data with any friendly platform.

Like EODAS (electro-optical Apparcha system), it has six electro-optic sensors that provide 360-degree coverage to the pilot; the same sensors process the fusion system radar signal with IR image, which causes the pilot from every situation Can be aware.

The Chengdu j20 is equipped with an EOTS86 electro-optical targeting system, and the system has been built by the Chinese company Astar Science and Technology, and with its help, this fighter can detect and kill other stealth fighters.

Its cockpit is equipped with a glass cockpit, which has two large main display which is a colour display which has been installed side by side, while it has three small auxiliary display, as well as wide-angle head of display. has been applied

The helmet mountain display has also been installed in the j20, which helps to target the pilot and use battle management information more efficiently.

Is Chengdu j20 really stealthy?

The front design of the Chengdu j20 is designed to be stealth saping like the f-22 raptor so that its front end performance is similar to that of the f-22 rapper.

But the design of its rear can expose it in front of the radar. That is why one of its prototypes was fitted with the WS10G engine, but it has not been so successful, the design of its rear is still in the works. It cannot be called a completely stealth fighter jet.

The engine has been the biggest problem for this fighter jet, mainly in China, the WS10 and Russia’s al31 engine have been used.

China is working on the ws15 engine for this fighter jet which is an advanced turbofan engine. The same thing has also come to light that China will use the S10 or 1175s engine in the j-20 which will be bought from Russia, but still, no such deal has been done.

Both short-range and long-range air-to-air missiles can be placed in the Chengdu j20 armament, while two short-wave ways are also placed behind the inlets in which the short-range air to air missile can be placed. Might

Along with this, PL8, PL12 short-range air to air missile PL12 medium-range air to air missile can be placed in j20.

Along with this, LS6 guided bombs can also be placed in it.

All the features of this fighter jet make it a true 5th generation fighter aircraft. If it can overcome the engine problem, then it will be a deadly fighter plane as fighter jet f-22 raptor.

So this was the complete information about the Chinese fifth-generation fighter aircraft Chandu j20.
