A J-10 purchase would force Egypt to build a new support system

What would Egypt gain or lose by buying J-10 fighters and Chinese missiles instead of Rafales and Western weapons?

The aircraft could add useful capability, but Egypt would have to change its training, maintenance, and supply system while Chinese missile factories are also described as heavily committed.

A J-10 purchase could give Egypt a useful fighter and access to Chinese weapons under the question's assumption that suitable Western missiles remain unavailable. Supporting the aircraft would require changing the entire logistics and training system supporting it. Existing skills would need replacing or adapting more extensively than when upgrading within the same design and supply system. Gripen is mentioned as another possible aircraft option, without a detailed comparison. Chinese missile factories are also described as heavily committed, alongside Western and Russian production. The wider industrial point is that production capacity sized for continuing peace cannot immediately meet wartime equipment demand.
