Many military fans already know about the situation of domestic transportation 20B replacement WS20 aircraft engine. Of course, even if the WS-20 is already very mature, after a major upgrade of a model of aircraft engine, a series of regular tests will inevitably be carried out. Although this is cumbersome as a model production, it is also an indispensable step. Recently, there has been reports that the yellow paint version of Yun 20B appeared. This is after the green skin version of Yun 20B, and the Yun 20B was unveiled again. Military fans speculated that Yun 20B is about to enter the final production stage.

According to social media reports, we have seen the unveiled version of the Y20B yellow paint. The biggest feature of this version is that it has been replaced with a WS-20 engine and no longer relies on Russian aircraft engines. It not only improves performance, but also lays the supply chain foundation for the further increase of quantity.

From the picture, the yellow paint version of Yun 20B is not much different from the green leather version of Yun-20B, and it should have been re-primed. The green leather version is generally used for testing and test flights, while the yellow paint means that the test has been completed and the mass production stage is entered. A layer of low-visibility Air Force gray paint is applied on the outside of the yellow paint primer, which is the official appearance of the Y20B. It can be said that this Yun20B will be the first complete body of the Yun20. Its WS-20 aircraft engine can truly take advantage of the design advantages of the Yun20, and this improvement will continue to appear on the Yu-20. The new model is probably the Yu-20B. At that time, the domestic Yun20 platform will basically achieve the best performance.

Many military fans speculated that after the Y20 reached its complete body, the utilization range of its platform would be wider. It is currently speculated that the new generation of large strategic early warning aircraft, large electronic warfare aircraft, nuclear submarine long-wave communication aircraft, nuclear war air command center, etc. may use Y20 as a platform. For the Air Guard 2000, which uses the Il-76 platform, due to the limited number of aircraft models and the need to be introduced, the actual number of aircraft is actually difficult to increase. Although the performance of the digital phased array radar in the later stage has been improved and is a third-generation early warning aircraft, the Y9 platform used is a medium-sized transport aircraft after all, and the carrying capacity, range and air stagnation time are limited by the platform, so it is difficult to become a strategic transport aircraft to replace the Air Guard 2000. The complete body of the Y-20 that is replaced with WS-20 can obviously adapt to the tactics of large special fighters going out in the future and can provide better flight performance in the depths of the ocean.

As for models such as long-wave nuclear submarine command aircraft and nuclear combat air command posts, it is also very common in the West, such as Il 80, E-6B "Mercury", etc. These models are all strategic uses. In fact, China does not lack relevant technologies. The only thing we need is a platform that can meet the performance. After the WS-20 version of the Y20 is finalized, it will obviously solve the platform problem. I believe that the strategic command model based on the Y20B will not be too far away.

Overall, the current development of the domestic Yun-20B is still very smooth, thanks to the smooth development of large bypass engines such as WS-20. In the past 10 years, all domestic aircraft engines have invested a lot of manpower and material resources. As the material technology and processing level gradually reach the level of an industrial power, domestic engines have also ushered in a booming harvest period. This time, the WS-20 of the 20B is just the beginning, and more small bypass ratios, medium push and vector vent aeronautical engines are also developing rapidly. At that time, the rapid development of the domestic strategic air force is still very likely to be achieved.
