>There is no such thing as a next gen engine.

The , next gen jet engine have stealth feature and also engine with adaptive cycle are under development.

>Also 5th or 6th gen planes...claimed ones? developed ones? claimed to be developed ones? If we are talking about the latter then shooot we have many of those, even former Yugoslavia claimed to have developed a stealth fighter.

I am talking about jet engine not planes

>Calling out certain brands also makes little sense since most NATO members and NATO alies are codeveloping engines now a days. EJ200 was British/German/Italian/Spanish companies co-developing it. F136 upgrade to P-W F135 was a G-E/Rolls Royce co-development.

Most of the development was still done my one of 2 Major countries so it does makes sense

>No idea where China stole it's designs, but they did upgrade them past what they were.

Chinese engine are very similar to Russian ones and they also took the same approach of upscaling engine like Russian which caused it to be very inefficient

>The indian engine has been in a test/research stage for ages and will continue to be in a test research/stage for at least a decade or two.

No, it just completed its test with new core recently in russia and it's dry variant will be uses in the Ghatak UCAV by 2024-2026

And if u just count making engine , then india has been making engine for su-30mki and Mirage 2000 from scratch for quiet a while

Also india is working in co-development with saffran or Rolls-Royce to develop a new 140kn engine
