My point is that LRIP is unique to American defense procurement; countries like Russia and China may use similar processes but it's not the same. You have to remember, various F-35 models during the LRIP process couldn't even fire their guns. In the United States' case, it's a sort of a scam, an attempt to say that an aircraft that's still in the beta process is fully operational and that issues are with the production process, not the development process.
In China's case, the J-20 was declared operational by the PLAAF. Moreover, LRIP in the J-20's context implies that either the WS-10X or AL-31-engined J-20s are going to be put into mass production at some point, when we expect the J-20 instead to go through A, B, C stages like the J-11s and J-10s.
That is to say, the J-20s and J-20As may ALWAYS be in the equivalent of LRIP; LRIP is simply not applicable. The J-20B and J-20Cs using more advanced engines, on the other hand, may be produced at higher volumes. In this context, does it make sense to claim that the J-20 is in LRIP?
