Been out for a couple of years, but naming Russian and Chinese kit definitely didn't stop in the late 1990s. J-10 FIREBIRD. I think Su-57 FELON was announced last year, or maybe even this year? Confirmed it again today, J-20 FAGIN. It's the name of the character from the book, nothing to do with any Chinese words. If you know any fast jet aircrew or INT types they will be able to confirm it.
