Some new photos of new version of J-20 with new stealth coating have recently been posted on the Internet.
The New J-20 no. 2011 shines bright in the photos with silvery coating.
Some web users exclaimed that it looked like a sci-fi galaxy fighter jet and simply mad one blind by its brightness.
Analysts say that the new coating makes the fighter better undetectable.

Linglong stealth carrier-based fighter jet

J-15 carrier-based fighter jets, though a rival to any existing carrier-based counterparts, is no rival to US F-35 stealth carrier-based fighter jets. There is the disparity of one generation.
Therefore, China must develop a new carrier-based fighter jet to deal with US F-35C.
Recently China’s next generation of heavy stealth carrier-based fighter nicknamed “Linglong” (J-20BH ?) has become a hot topic on the Internet.
It is said that Linglong has been developed on the basis of China’s J-20 stealth fighter.
So far Linglong is only one of the plans for the development of China’s second-generation carrier-based fighter jets. There are many other plans proposed to the State for selection. Linglong is special in having swept wings in its design.
Writer’s note: What differs China from other nations is that aircraft producers may carry out their own plans on their own with their own fund even if their plans are not accepted by the State. They want to compete with the plan accepted by the State. If their plan finally proved better than the accepted plan, they will certainly obtain orders from the State. Even if their version is inferior to the State one, they can export the fighters they have developed to recover their investment. As their production cost is much lower than US, they will certainly grab a large market share from the US.
That is the case with J-31 that China has been developing. The State has only accepted the plan for J-20, J-31 has been developed without any fund from the State. However, if it proves good, the State will certainly place quite a substantial order for it as it provide a lighter stealth fighter to supplement J-20 the heavy stealth fighter.
Chinese weapon producers are all owned by the State. For their management, satisfying the State’s needs for advanced weapons is much more important than profit; therefore, it is common for them to spend the profit earned from civil products in developing the weapons the State needs.

Engine for VTOL aircraft

The injection of huge fund and Chinese scientists and engineers’ enthusiasm to realize their China dream enable China to achieve fast development of its advanced aircraft engines and soon surpass the United States.
For example, Both Russian and US medias speculate that China has made breakthrough in developing WS-15 engine for its stealth fighter jet J-20 so that the fighter will be able to use China-made engines to be free of its dependence on Russian engines.
It is said that WS-15 is the core of China’s SF-A engine with a thrust 28,700 lb, which if used in J-20 heavy stealth fighter will make it surpass the US in power and maneuverability.
Moreover, as China imported Russian Yak-141 VTOL technology, the WS-15 will have a curved nozzle to enable it to take off and land vertically at a short distance so that J-20 will be China’s next generation of carrier-based fighter jets.
However, China’s ambition does not stop here.
It has developed WS-20 engine with a thrust-to-weight ratio above 9 for its Y-20 large transport aircraft and WS-118 (also known as WS-20 or CJ-2000) engine with a thrust of 26,500 lb that has already been used on its J-10 and J-11B fighter jets. Research and development has begun for a new generation of medium-thrust engine with thrust-to-weight ratio exceeding 9. Preparations are being made for test flight of the aircraft installed with WS-15 fourth-generation engine with a thrust-to-weight ratio of 10.
Test flight of its aircrafts using an improved version of Taihang Engine will be conducted in the coming few years to provide power for China’s new generation of stealth drones, stealth attack drones, long-range drones and manned long-range stealth bombers. At the same time preliminary research has begun in developing an improved fourth-generation military engine with a thrust-to-weight ratio of 12.
As the best US engine F-119-PW-100 used by F-22 stealth fighter jet has only a thrust-to-weight ratio of 8, the above engines Chins is developing fully indicate China’s ambition to surpass the United States.
Engines for civil aircraft are not neglected. An engine with a trust of 30,000 lb is being developed in Shenyang not only for large military transport but also for C-919 large airliner China is developing.
