Why doesn't the PLA go for Chinese airliners for its requirements?
This issue has sparked heated debate on Chinese social media platforms, but there's no clear conclusion.
IMO.
We won't see the PLA undergo a large-scale transition of its military special aircraft platforms from the Y series (Y8/Y9/Y20......) to the C9x9 series (C909/C919/C929......).
Military and civilian aircraft platforms differ significantly in practical applications.
Fuselage structure and interior space, runway requirements for takeoff and landing, aircraft flight performance, and the ease of platform modification......
If you are interested, you can ask AI for the specific details.
Both platforms have their own advantages and disadvantages. There's no clear comparison of which is better. Each country should make its own choice based on its own circumstances.
The PLA's current military special aircraft fleet is in the hybrid phase of manned and unmanned operations. According to official sources, major Chinese military enterprises are fully committed to increasing investment in unmanned military special aircraft. This means that the PLA will largely unmanned its military special aircraft in the future, with manned aircraft only performing a very small number of missions. I believe this may take about 10-20 years.
The PLA currently possesses a large number of Y-series military special aircraft. If the PLA were to fully convert these to the C9x9 series, it would be equivalent to completely rebuilding the PLA's military special aircraft maintenance system, a process that would take at least 10-20 years.
The C9x9 series of civil airliners is manufactured by COMAC in full compliance with the universal rules of the international civil aviation system. Many of its components come from foreign suppliers. This isn't because China can't manufacture these components, but rather the result of a trade-off in commercial interests.
In the early days of COMAC's development, in order to expand into the international market, we had to make some trade-offs with Western developed countries. If all the components of the C9x9 series of civil airliners were 100% manufactured in China, Western developed countries would never allow these aircraft to appear in their countries. But, the PLA is unlikely to allow its military special aircraft to contain a large number of Western components.
Therefore, COMAC must first reach agreements with Western countries and adopt a large number of Western components. After gradually gaining market share, they can then gradually increase the proportion of domestically produced parts. Regarding the engine issue raised by some friends, this is not the core issue. The CJ-1000/CJ-1000A is already ready.
Summary:
When the C9x9 series civilian aircraft platform meets the PLA's requirements (in terms of domestic production ratio), the PLA's military special aircraft will have entered the next era and will no longer require such platforms in large quantities.
A small number of experimental modifications are not within the scope of this discussion.
