Chengdu J-20 is the fifth generation twin engine ghost fighter aircraft developed by the Chengdu Aircraft Industry Group. The J-20 made its first flight on January 11, 2011 and went into service in 2017.
The 5th generation indigenous force of the Chinese People's Liberation Army Air Force, the J-20, is an indicator of the technological power that China has reached. The aim of the J-XX project, which was initiated in the 1990s, was to obtain the necessary technology for an advanced fighter aircraft needed by China. The J-XX program has been specific since the 2000s. zamIt created 3 new projects at intervals of time. These became: J-20, J-31 and H-20.
The F-35, F-22, Su-57, TF-X, HAL UNCLE, KF-X equivalent 5th generation fighter jet J-20 was adopted by the Chinese Air Force in 2008 and it was decided to be produced as a prototype. J-2011, which successfully performed its first flight in 20, was produced in 2009 and the prototype was made ready for flight in 2 years. Taxi (ground / runway) tests were carried out successfully in 2010. As of the date of entry into service, 10 March 2017 was registered. When the program was started, the unit cost (according to 2011 data) was 120 million dollars, while it is 2016 million dollars according to 60 data.
Some design changes occurred on the plane until it came into service. After the first flight in 2011, many structural designs, hardware features and equipment were changed until October 2017. Chinese media reported that the aircraft gained full combat capability in October 2017.
Currently, there are 28 J-20s in the Chinese Air Force inventory. While mass production continues, the aircraft's development activities continue. In the past weeks, the J-20 has been tested with the WS-10C engine, which is stronger in terms of its 'radar invisibility' feature. However, the WS-10C does not have thrust steering.
If we take a look at the technical specifications of the J-20
The radar type of the J-20 has not been shared with the public, but military experts report that the J-20 is equipped with the Type 1475 (KLJ-5) AESA radar, while some military experts already have an improved version of the Type 1475. reports that an attempt has been made to integrate with.
The aircraft has electro-optical targeting systems. It has similar features to the AN / AAQ-86 used in the EOTS-35 electro-optical targeting system F-37 developed by a Chinese company.
Russian-origin Saturn AL-20F engine was preferred for the J-31, which was designed and produced as a double engine. The first prototypes produced by China were the WS-10B used in the J-10. Working on a new engine that will not risk the invisibility feature on the radar and calling it WS-15, China continues its tests, but military officials believe that China will not be able to raise it until 2020. It comes from efforts to integrate an engine called WS-2020C into the J-10, which China describes as an 'intermediate solution', with the idea that it will not reach 20. WS-10C performs better in radar invisibility technology and serves in 14 (+) tone class. However, the WS-10C is reportedly lacking propulsion steering technology.
The 'low visibility on radar' feature of every 5th generation aircraft is one of the features of the J-20. The biggest problem of the J-20, which has an internal armament station, was its engines. The engines could not meet the requirements of this feature and put the feature in danger. China is in this effort to develop new engines.
W-20's Weapon Systems
- PL-8 Short Range Air-Air Missile
- PL-10 Short Range Air-Air Missile
- PL-12 Medium Range Air-Air Missile
- PL-21 Long Range Air-Air Missile
- LS-6 Precision Guided Bomb
These weapon systems are the systems that support the J-20's 'Stealth' radar invisibility feature.
The United States made a statement to the J-20 program, especially the first flight made in 2011, 'the first flight was not a surprise, we were following the program' and subsequently underestimated the plane with the explanations of 'J-20 will fail in air-air struggles and how secret program can be'. . In its annual reports published in 2011, the Pentagon referred to the J-20 as "a platform capable of serving in long-range and complex air defense areas."
In the reports published in 2014-2015, it was reported that underestimation of the plane was an error and the comments made by looking at the first view of the plane were incorrect. It is reported that the J-20 threatens the U.S. maritime elements with its developing and changing technology, and therefore, the F-22 reinforcement has been implemented in the coastal regions of the USA. For the J-20 with radar invisibility, the US E-2D Advanced Hawkeye relies on the airborne early warning aircraft.
There is another information about the J-20. It is stated that the technology of J-20 is equipped with F-35 technology by Chinese hackers. In a cyber attack carried out by China in the Wall Street Journal report published in 2009, the critical technological software and information of the F-35 was captured by Chinese hackers. A British F-35 pilot told some hackers some of the critical technologies of the F-35 through the Tinder app, according to a recent report. This information was shared with third parties.
The Tinder account of the female pilot was seized and conversations were initiated with another air force officer in the same area. From there, critical digital software information was captured, and the Royal Air Force confirmed that the leaked information was shared with third parties. Experts think this is an attempt to make you forget the incident in 2009 and to divert the error / crime to another side.
