J20 China’s Fifth Generation Aircraft

J20 China’s Fifth Generation Aircraft

The Chengdu J20 China’s fifth generation aircraft, It is single-seater, twin jet, all-weather, stealthy aircraft developed by China’s Chengdu Aerospace Corporation.The J-20 developed for an air superiority with precision strike capability for the People’s Liberation Army Air Force (PLAAF).
J-20 known as Mighty Dragon because of its features (Stealthy and air superiority fighter) and it is the world’s third operational fifth-generation stealth fighter aircraft after the F-22(US) and F-35(US).

J20 China’s Fifth Generation Aircraft :First flight and Status

China made its first J-20 prototype maiden flight On 11 January 2011 and after went through sevral changes and testing, On Sept 2017 J20 was officially entered in service.
During the initial phase of induction J20 was using russian engine, now J20 came to mass production with own developed Jet engine WS-10,WS-10B.

J20 China’s Fifth Generation Aircraft : Design and structure


The J-20 has a very long and wide fuselage than any other current fifth genation fighter in world, with a chiseled nose section and a frameless canopy. Delta wing with forward-swept trailing edge and moving canard surfaces with pronounced dihedral are placed behind the intakes with conventional round engine exhausts.
And canard design is also known to provide good manuoverability with supersonic performance and improved short-field landing performance.

J20 China’s Fifth Generation Aircraft : Features

J20 is used active electronically scanned array (AESA) radar with transmit/receive modules and it provide 360-degree coverage for pilot with electro-optical targeting system and Electro-Optical Distributed Aperture System to detect and intercept stealth aircraft.
It has glass cockpit, with one main large color LCD touchscreen, three smaller helping displays, and holographic head-up display. J20 has internal weapon bay is can carry shot and long air to air missile(PL15,PL21), also can carry outside of bay.

Is J20 is any Good :

According to chines govt and its frontline news angency they Consider J20 as good as Us F22 and F35. But there are some other controvesries over J20 aircraft too
regarding its stealthyness, super cruise capabilty of jet engine which raise the question on this Fifth generation of aircarft.
So we are comparing in details with world best fighter aircaraft, which is the best aircarft of acuurent Era.
In belwo we are seeing the comparision with F22,F35 and Rafale.

J20 China’s Fifth Generation Aircraft : Controversis

1) “Supercruise”, is the ability to fly supersonic speed without the using of afterburner of jet engine, so according to many defece expert china’s J20 does not have ability to supercruise.
2) The J20 is not good short range dogfight engagements with other aircraft due to lack of an internal autocannon or rotary cannon.
3) Use of canards on a low-observable design, stating that canards would guarantee radar detection and a compromise of stealthiness.
4) There is some rumers that the compromise of the F-35 program may have helped in the development of the J-20.

How many J20 does China have :

Till the today’s date consider month of Sept 2020, in records it shows there are around 50+ aircraft in the active service.

Is Rafale better than J20?

Rafale better than J20

Though Rafale is 4.5 generation aircraft but still it consider as much better than Chinese J20 and below are the reason why?

  1. Rafale aircraft can super cruise but J20 cannot because China yet not able to manufactured Fifth generation Jet Engine. So its J20 powered by low power jet Engine(WS-15)
  2. Rafale has one of the most advanced Electronic warfare system inbuilt in it, so it is very difficult to track Rafale by any Radar system. And Because of its Anti jammer system no other Jammer can Jam its Radar and its missile.
  3. Rafale has battle proven aircraft (In Turkey, Syria ) but J20 has not battled in any war.
  4. The most important Point is Rafale is best at close combat engagement with other aircraft (dogfight), beacuse of inbuilt canon gun in Rafale.
  5. Rafale can carry much variaty of payload weapon greater than its weight.

Is J20 better than F 35?

F35 better than J20

F35 is far better fifth generation fighter aircraft and Proven its worthiness time to time in every war, which is used by most of Nato allies country. Below are the point mentioned why J20 is no comparison to F35.

  1. F35 aircraft can super cruise but J20 cannot because China yet not able to manufactured Fifth generation Jet Engine. So its J20 powered by low power jet Engine(WS-15)
  2. F35 has most advanced Electronic warfare system inbuilt in it, F35 is one the best stealthy aircraft as its engine mounted in side the structure which avoid the heat signature being detected by any Radar. This case not applicable in J20.
  3. F35 is mainly built for air to air and air-to ground operation but still F35 has more advantage over J20 in dogfight as F35 has in built canon gun.

Is J20 better than F 22?

F22 is  better than J20

F22 is the first ftfth generation fighter aircraft which created 23 year ago than J20. Though its very older than J20, but not just J20 or any other fifth generation aircraft has no match to this air superior aircraft.

This is best aircraft till date that US had manufactured, that’s why US govt is so concern and secretive about this aircraft. That Us govt. never gives this master piece to any one even its friendly nation.

So there is no reason to compare this beast F22 with J20.

  1. F22 aircraft can super cruise but J20 cannot because China yet not able to manufactured Fifth generation Jet Engine. So its J20 powered by low power jet Engine(WS-15) as F22 is air-superior highly maneuverable,stealthy aircraft.
